    description
    Background of the Invention The present invention relates to a heating system with a container for holding liquid metallic material, comprising a heating device for heating the container and a conversion for the container and a method for heating such a container in such a heating system.
    In metal processing, containers for holding liquid metallic material are heated and dried by heating before they are filled with the metallic material. The container or the wall of the container is generally heated by a burner flame extending into the interior of the container. Heating the container, e.g. a pouring ladle, is imperative to avoid thermal shock of the container when filling it with the liquid metal. If the container were not heated, it would be severely damaged by thermal shock when it was filled with the liquid metal, and the filled-in liquid metal would run out of the container through cracks in the container which are formed in the container due to the temperature shock.
    Suitable containers for holding liquid metal or for filling with liquid metal, e.g. Casting ladles often have a wall, which at least in some areas comprises an outer wall area made of a metallic material such as steel, and an inner wall area, the inner wall area serving as a protective area to avoid contact of the outer wall area with the liquid metal to be filled. This inner wall area usually has refractory or heat-resistant materials that can withstand the high temperatures of the liquid metal and, in particular due to their low thermal conductivity, protect the outer wall area from exposure to an excessively high temperature. This prevents damage, in particular melting of the outer wall area when the container is filled with the liquid metal. Typically, the inner wall area usually comprises masonry made of pitch-bonded and / or resin-bound refractory bricks.
    In the heating of the container or the wall of the container described above - in particular e.g. Exhaust gases are formed as a result of the heating of the wall via a burning flame extending into the interior of the container. These usually flow out of the container via gas discharge channels or sweat holes in the container and / or the gap between the cover for covering the filling opening of the container and the container together with other gases, in particular air. The exhaust gases can in particular also be hydrocarbons, which are contained in the binder of the stones of the masonry of the inner wall area and escape through heating at temperatures from approximately 350 degrees Celsius. In the device known from DE 20 2004 012 566 U1, these exhaust gases are collected together with the other gases in the interior of a modification of the container in the form of a pot-like pan pit. In the device known from DE 20 2004 012 566 U1, exhaust gases that have entered an interior can be partially extracted from the interior via a ring line provided in the upper region of the interior. However, it has been shown in practice that this suction solution known from DE 20 2004 012 566 U1 is in need of improvement.
    Underlying object The present invention has for its object to provide a heating system with a conversion for heating the container and a method for heating the container with such a heating system for a container for receiving liquid metallic material, with which the heating up of the container-forming exhaust gases that have flowed into the interior of the conversion can be better extracted from the interior.
    Solution according to the invention This object is achieved according to the invention with a heating system with the features of claim 1 and with a method with the features of claim 5.
    The heating system according to the invention with a container for heating the container for holding liquid metallic material or for holding liquid metal comprises a heating device and a conversion for the container.
    The container has a container opening through which the container can be filled with the liquid metallic material.
    The remodeling delimits an interior space with a floor or the remodeling delimits an interior space that is also delimited by a floor.
    The conversion, which can in particular also be a conversion that can at least partially consist of a metallic material, has an insertion opening for introducing the container into the interior.
    The heating device has at least one burner, a covering device for covering the insertion opening and a cover for covering the container opening.
    CH 710 496 B1 The burner is attached to the lid. The burner is configured to generate a burning flame that extends into the container to heat the container when the container opening is covered by the lid. The burner can be a conventional burner known to the person skilled in the art for heating a container for holding liquid metallic material or for holding liquid metal, in which the burning flame is obtained in particular by burning a supplied fuel gas / air mixture or fuel gas. Oxygen mixture is generated.
    The lid for covering the container opening serves, among other things, to prevent the outflow of gases - in particular exhaust gases which arise during the heating of the container with the flame - into the surroundings of the heating system or the interior. In particular, the cover serves to avoid excessive loss of the thermal energy introduced into the interior by the burner. However, the fact that the lid prevents the outflow of gases through the container opening does not necessarily mean that the lid completely prevents the outflow. In practice, the structural conditions are usually characterized in particular by the fact that the container openings of differently designed containers, such as in particular ladles, are usually covered with a cover of the same design, the container openings also being designed differently and / or being partially soiled. Due to these structural conditions, gaps usually form between the lid and the container, through which the gases or exhaust gases can flow out. The same also applies to the covering device for covering the insertion opening. The covering device can hinder the outflow of gases from the interior via the introduction opening, but this does not necessarily mean that the covering device completely prevents the outflow. In practice, gases or exhaust gases can flow out into the surroundings of the heating system via gaps between the covering device and the conversion.
    The lid and the covering device can be designed in a manner known to those skilled in the art. In particular, the cover and the covering device can consist of a metallic material or metallic material at least in regions.
    The container or the wall of the container can be heated or heated by the burning flame generated by the burner in such a way that a thermal shock of the container when it is filled with the liquid metal or liquid metallic material can be effectively avoided.
    In particular when the container or the wall of the container is first heated, exhaust gases are formed due to the heating of the wall, which in particular as a result of the excess pressure built up by the flame inside the container and / or due to other causes in the wall of the Exhaust gas discharge channels or exhaust gas discharge holes or sweat holes provided in the container and / or flow out of the container via gaps between the cover for covering the filling opening of the container and the container and / or via further leaks together with other gases, in particular air.
    The from the container provided in the wall of the container exhaust gas discharge channels or exhaust gas discharge holes or sweat holes and / or through gaps between the lid to cover the fill opening of the container and the container and / or any other leaks from the container escaping gases flow into the interior of the conversion, in which the container, which in particular, for example can be a ladle, has been inserted before heating. The conversion or the interior of the conversion is provided in particular for the collection or interception of these exhaust gases so that they do not escape unhindered into the environment, which is problematic in particular for reasons of environmental protection and personal protection.
    The exhaust gases can in particular be exhaust gases which, e.g. a container with an inner wall area escape from this wall area. The inner wall area - which serves as a protective area to avoid contact of an outer wall area with the liquid metal to be filled - can, e.g. In ladles, it is customary to deal with a wall region which comprises heat-resistant or refractory materials and which can in particular be in the form of masonry. In this embodiment of a container, the exhaust gases escape from the masonry as a result of heating by the burning flame of the burner, the exhaust gases in particular being hydrocarbons which are in the binder of the stones or refractory stones (which are usually pitch-bonded Refractory bricks and / or synthetic resin-bonded refractory bricks are contained in the masonry and escape from the binder by heating to temperatures above approx. 350 degrees Celsius.
    The heating system according to the invention has at least one suction device for suctioning (or sucking out) gases from the interior. The gases are any gases in the interior, in particular also air. In particular, the exhaust gases which are produced or released when the container or the container wall is heated can be extracted from the interior into which the container was introduced via the introduction opening. The exhaust gases are the exhaust gases (cf. also above), which together with other gases (in particular air) via exhaust gas discharge channels or exhaust gas discharge holes or sweat holes of the container or the container wall and / or via gaps between the cover to cover the Filling opening of the container and the container and / or other leaks, in particular as a result of the excess pressure built up by the flame in the interior of the container, or have flowed into the interior.
    CH 710 496 B1 The exhaust gases sucked out of the interior by the extraction device can be burned to avoid environmental pollution, the exhaust gases together with the other extracted gases being e.g. can be supplied to the burner or the flame of the burner.
    The suction device can be a typical suction device known to the person skilled in the art, which e.g. may comprise a turbomachine or a mammal pump with one or more fans.
    In the heating system according to the invention, the conversion for extracting the gases through the extraction device has at least one extraction channel through the conversion with an inflow opening. The inflow opening is provided on an inner side of the conversion facing the interior. The gases can flow into the suction channel via the inflow opening. The suction channel can be designed in a manner known per se. In particular, the suction channel can comprise an opening penetrating the wall of the container or a cutout penetrating the wall of the container, which extends from the inside of the container to outside of the container or into the outside of the container.
    The heating system according to the invention is characterized in that the height difference between the highest point of the inflow opening and the lowest point of the floor is at most 0.8 times the greatest height extension of the interior. As a result of the lowering of the inflow opening provided in this way in comparison with the device known from DE 20 2004 012 566 U1, the exhaust gases formed as a result of the heating up of the container and flowing into the interior from the container can be extracted much better. This is a consequence of the fact that the exhaust gases formed in the interior of the container are exposed to temperatures e.g. typically above 360 degrees Celsius, when they enter the interior at a temperature of at most 30 degrees Celsius, are cooled very strongly. This strong cooling results in a large increase in the density of the exhaust gases, which in turn is accompanied by a decrease in the exhaust gases. It has also been shown in practice that the gases which enter the interior via exhaust gas discharge channels or exhaust gas discharge holes or sweat holes of the container or the container wall are already cooled during the passage through the container or the container wall, while the gases , which penetrate into the interior through a gap between the lid and the container, do not experience such a cooling and therefore tend to linger in the upper region of the interior.
    With a height difference between the highest point of the inflow opening and the lowest point of the floor, which is at most 0.8 times the greatest height extension of the interior, the highest point of the inflow opening is so deep that the interior suction is opposite the solution known from DE 20 2004 012 566 U1, in which the suction takes place in higher areas of the interior of a conversion, is significantly improved. In particular for the heating of containers in the form of pouring ladles, which are provided with exhaust gas discharge channels or sweat holes for discharging the exhaust gases into the interior of the conversion, the extraction or the extraction performance can be significantly improved by means of the heating system according to the invention. A suction device known from DE 20 2004 012 566 U1 in higher areas of the interior space, on the other hand, has the disadvantage that the cooled gases or exhaust gases accumulating in the interior space at the bottom cannot be effectively sucked out of the interior space or are not sufficient from the suction flow can be detected, which results in a disadvantageously high concentration of the exhaust gases in the interior, which in practice is often also characterized by a disadvantageous clear darkening of the interior.
    Considered overall, can be provided by providing the height difference between the highest point of the inflow opening and the lowest point of the floor, which is at most 0.8 times the greatest height extension of the interior - or by providing an inflow opening, the highest point in a height which is measured from the lowest point of the floor and which is at most 0.8 times the greatest height extension of the interior - the exhaust gases which form when the container is heated and which have flowed into the interior of the conversion are extracted much better from the interior ,
    The greatest height extension is to be understood (in a known manner) from all possible vertical distances from different points or areas of the floor to the upper end of the interior, or the greatest distance is (in a known manner) from all possible vertical distances from different points or areas of the floor to the upper end of the interior to understand the distances that all have the same or the same greatest vertical distance from all vertical distances.
    It is understood that there can be not only a single highest point of the inflow opening, but also several highest points of the inflow opening, all of which are at the same or the same highest height, which are z. B. dimensioned from a predetermined horizontal reference plane. The same applies to the lowest point on the floor. Of course, there can be not only a single lowest point of the floor, but also several lowest points of the floor, all of which are at the same or the same lowest height, e.g. measured from the given horizontal reference plane.
    It also goes without saying that the conversion which delimits the interior does not necessarily have to be a conversion without passages extending into the interior which enforce the conversion or the conversion does not necessarily have to be a conversion which completely completes the interior encloses seamlessly or seamlessly. As a conversion that only limits the interior, this can also be a passage e.g. to accommodate a door frame
    CH 710 496 B1 have a door or the like. In particular in the case of a heating system for heating a casting ladle, the interior space delimiting the conversion can generally be accessed via a door arranged in a passage in the conversion, in particular for carrying out maintenance work and / or assembly work.
    In a practical embodiment of the heating system according to the invention, the lid is part of the covering device. If the cover for covering the container opening is part of the covering device, the container opening can be covered in a simple and practical manner by covering the insertion opening with the covering device, provided the container is in a suitable position in the interior.
    Particularly preferably, the difference in height between the highest point of the inflow opening and the lowest point of the bottom is at most 0.1 times or at most 0.2 times or at most 0.4 times or at most 0.5- Times or at most 0.7 times the greatest height extension of the interior or particularly preferably the highest point of the inflow opening is arranged at a height measured from the lowest point of the floor, which is at most 0.1 times or at most 0, 2 times or at most 0.4 times or at most 0.5 times or at most 0.7 times the greatest height dimension of the interior. By lowering the inflow opening in this way, the exhaust gas extraction performance can be significantly increased or improved again.
    Preferably, the height difference between the highest point of the inflow opening and the lowest point of the bottom can also be 0.1 times (or essentially 0.1 times) or 0.2 times (or essentially) 0.2 times) or 0.4 times (or essentially 0.4 times) or 0.5 times (or essentially 0.5 times) or 0.7 Times (or essentially 0.7 times) the greatest height extension of the interior.
    In a further practical embodiment, the heating system has at least one gas line which is connected to an outlet side of the suction device, wherein the gases sucked out or extracted from the interior via the gas line can be fed to the burner as fuel gases and / or into the flame of the burner can be inserted. By providing the at least one gas line, especially polluted exhaust gases - in particular the exhaust gases formed as a result of the heating of the container and flowing into the interior from the container - can be completely or at least partially burned with the aid of additional air / oxygen, namely by Exhaust gases are burned as part of the fuel gases by the burner and / or by introducing the extracted gases, which also include the exhaust gases, into the flame for combustion. As a result of the combustion, the environmentally harmful exhaust gases can mostly be advantageously converted into harmless or largely harmless combustion products, e.g. Water and carbon dioxide.
    [0033] The method according to the invention for heating a container for holding liquid metallic material by means of a heating system according to the invention described above comprises the following steps:
    (A) inserting the container into the interior delimited by the conversion, (B) covering the insertion opening with the covering device and covering the container opening of the container with the cover, (C) heating the container by a burning flame generated by the burner until the wall of the container has a temperature which is at least partially or entirely at least 360 degrees Celsius, and (D) sucking out or sucking out gases from the interior during the heating of the container or the wall of the container and / or after the heating of the container or the wall of the container by the suction device or by activating the suction device.
    By naming steps A to D, of course, no link to a chronological order is pursued. The letters are only used to name or name the steps. Step D is thus carried out during step C or after step C, that is to say during the heating of the container or after the container has been heated. Step C comprises heating the container by a burning flame generated by the burner until the wall of the container has a temperature which is at least in some areas at least 360 degrees Celsius.
    Step B is carried out after step A and step C is preferably carried out after step B, but can also have a time period common to step B.
    The inventive method advantageously enables improved suction or removal of the exhaust gases flowing into the interior of the conversion in step C due to the lowering of the highest point of the inflow opening of the suction channel, as already explained above for the heating system.
    The gases are preferably sucked out of the interior and fed to the burner as fuel gases and / or introduced into the combustion flame via at least one gas line connected to an outlet side of the suction device.
    CH 710 496 B1 In this way, polluted exhaust gases can be burned entirely or at least partially with the aid of air or additional air and / or oxygen, specifically by burning the exhaust gases as part of the fuel gases or gases sucked out by the burner and / or by introducing the extracted gases, which also include the exhaust gases, into the burning flame, in particular to at least partially or completely burn the exhaust gases. By burning the environmentally harmful exhaust gases can mostly be turned into environmentally friendly or largely harmless combustion products, e.g. Water and carbon dioxide. Especially harmful or environmentally harmful hydrocarbon compounds (e.g. phenol, cresol and benzo (a) pyrene) can be completely or almost completely converted into largely harmless water and carbon dioxide by burning. Environmentally harmful hydrocarbon compounds typically arise when heating up a type of container that is provided with masonry that, as the inner wall area or as the inner partial wall of such a container, protects the mostly metallic outer wall area of such a container from direct contact with the liquid hot metal or metallic material to be filled , Containers in the form of ladles, in particular, are provided with such masonry, wherein environmentally harmful hydrocarbon compounds can escape from binders of the masonry when it is heated.
    In a practical embodiment, a container is heated with a wall which has a masonry facing the interior of the container or which has a masonry with a side facing the interior of the container. The masonry serves as a protective area to avoid contact of a mostly metallic outer wall area of the container with the hot liquid metallic material, for the receptacle of which the container is intended.
    BRIEF DESCRIPTION OF THE DRAWINGS Exemplary embodiments of the invention are explained in more detail below with reference to the accompanying drawings. It shows:
    Fig. 1 is a schematic partially sectioned representation of an embodiment of a heating system according to the invention, and
    Fig. 2 is a very schematic cross-sectional view of a container for holding liquid metallic material.
    The heating system 10 for heating a container 12 for receiving liquid metallic material or liquid metal comprises a heating device 14, a conversion 16 for the container 12 and a suction device 34 for suction of gases 36, 62 from the interior 20 Container 12 has a plurality of feet 76.
    The container 12 (see also the explanatory, very schematic cross-sectional illustration according to FIG. 2) has a container opening 18. The container 12 can be filled with the liquid metallic material (not illustrated) via the container opening 18. The container 12 has a wall 54 which has a masonry 56 facing the interior of the container 12 (or a masonry 56 with a side facing the interior of the container 54), which has an inner partial wall 66 or an inner wall region 66 of the wall 54 forms. An outer partial wall 64 or an outer wall area 64 of the container 12 consists largely of a metallic material. The masonry 56 comprises a large number of refractory bricks (not illustrated in more detail).
    The modification 16 delimits the interior 20 with the floor 22 or the modification 16 delimits the interior 20, which is also delimited by the floor 22.
    The modification 16 has an insertion opening 24 for introducing the container 12 into the interior 20.
    The heating device 14 has a burner 26, a covering device 28 for covering the insertion opening 24 and a cover 30 for covering the container opening 18.
    The burner 26 is attached to the lid 30.
    The lid 30 is part of the covering device 28. If the lid 30 for covering the container opening 18 is part of the covering device, the container opening 18 can, when the container 12 is in the interior 20 in the position illustrated for this purpose in FIG. 1 , are covered by covering the insertion opening 24 with the covering device 28 in a simple and practical manner.
    The burner 26 is configured to generate a burning flame 32, which extends into the container 12 for heating the container 12 when the container opening 18 is covered by the lid 30.
    An exhaust gas discharge 59 is mainly provided for the discharge of burner exhaust gases which are generated by the burner during the combustion of a supplied fuel gas-air mixture or fuel gas-oxygen mixture. To discharge the burner exhaust gases, the exhaust gas discharge is connected to an exhaust gas passage 72 provided in the cover 30.
    The element 74 is a fan.
    CH 710 496 B1 When the container 12 or the wall 54 of the container 12 is heated, exhaust gases 62 are formed due to the heating of the wall 54, which, owing to the excess pressure built up by the flame 32 inside the container 12 and / or due to other causes via the exhaust gas discharge channels 58 or sweat holes 58 provided in the wall 54 of the container 12 and / or at least one gap 60 between the cover 30 and the container 12 and / or via further leaks together with other gases 36, in particular air, Flow out of the container 12 and flow into the interior 20. The exhaust gases 62 are in particular also environmentally harmful hydrocarbon compounds which are formed from the binders of the masonry 56 when the container 12 is heated by the burner 26.
    For the extraction of gases by the suction device 34, the conversion 16 furthermore has an extraction channel 38 with an inflow opening 40 passing through the conversion 16. Gases located in the interior 20 and thus also the gases 36, 62 flowing into the interior from the container 12 can be flowed into the suction channel 38 via the inflow opening 40 and can be sucked out or sucked out of the interior 20 via the suction channel 38 by means of the suction device 34.
    The inflow opening 40 is provided on an inner side 42 of the wall 16 facing the interior 20. The difference in height 68 between the highest point 44 of the inflow opening 40 and the lowest point 46 of the bottom 22 is at most 0.8 times the greatest height extent 70 of the interior 22, namely approximately 0.3 times the greatest height extent 70 of the interior 22. This lowering of the inflow opening 40, which is provided in comparison with the device known from DE 20 2004 012 566 U1, in particular allows the exhaust gases 62 formed as a result of the heating of the container 12 and flowing into the interior 20 from the container 12 together with the other gases 36, in particular air, are sucked out of the interior 20 much better, due to the fact that the inflowing gases 36, 62 sink down as a result of the cooling as they enter or flow into the interior 20.
    The heating system 10 also has a gas line 48 which is connected to an outlet side 50 of the suction device 34. Gases sucked out of the interior 20 - in particular the gases or exhaust gases 36, 62 formed as a result of the heating of the container 12 and flowing into the interior 20 from the container 12 - can be supplied to the burner 26 as fuel gases via the gas line 48. Cumulatively or alternatively, the gas line can also be set up in such a way that the gases can be introduced directly into the combustion flame 32 of the burner 26 as fuel gas.
    [0056] A method for heating the container 12 for holding liquid metallic material by means of the heating system 10 comprises the following steps:
    (A) inserting the container 12 into the interior space 20 delimited by the conversion 16, (B) covering the insertion opening 24 with the covering device 28 and covering the container opening 18 of the container 12 with the cover 30, (C) heating the container 12 by a Burning flame 32 generated by the burner 26 until the wall 54 of the container 12 has a temperature which is at least in some areas at least 360 degrees Celsius, and (D) sucking gases out of the interior 20 during the heating of the container 12 by the suction device 34.
    For this method, the situation during the execution of the steps C and D is illustrated in FIG. 1 - after the steps A and B have been carried out.
    In the method, gases (especially air) located in the interior 20 and in particular also the gases or exhaust gases 36, 62 which have flowed from the interior of the container 12 into the interior 20 are sucked out of the interior 20 and via the outlet side 50 of the suction device 34 connected gas line 48 fed to the burner 26 as fuel gases.
