    Name of the invention
    Probe for a sublance with radial acquisition of images
    Technical field
    The present invention is based on a probe for a sublance of a converter vessel having a lance axis,
    the probe can be connected to the sublance, in particular can be plugged onto the sublance,
    the probe has a camera system,
    at least one image from the surroundings of the sublance can be captured by means of the camera system when the probe is connected to the sublance,
    the image having a large number of pixels,
    - The camera system is shielded from the surroundings of the sublance by means of a transparent structure, so that for those pixels which represent an image of a location from the surroundings of the sublance, a respective connecting line from the respective pixel to the respectively depicted location from the surroundings of the Sublance penetrates the transparent structure at a respective penetration point.
    The present invention is also based on a sublance of a converter vessel, the sublance being connected to such a probe, in particular the probe being plugged onto the sublance.
    State of the art
    Such a probe is known for example from JP H10 088 221 A. With this probe, the camera is arranged inside a cladding tube, the front end of which is closed by a disk made of quartz glass. This probe can be used during a process break (if there is no liquid / 27
    201700013 ges metal in the converter), for example, an image of the converter bottom can be captured.
    A camera system for use in a converter is known from CN 205 133 651 U, the camera of which is designed as an infrared camera.
    Summary of the invention
    Converters (so-called Basic Oxygen Furnace = BOF) are often used in the steel producing industry. These converter vessels are heavily soiled during operation. In order to be able to guarantee a flawless and above all fault-free operation, the condition of the contamination of such a converter vessel must therefore be checked regularly.
    Contamination is particularly evident in the area of the converter opening (= converter mouth) as an accumulated slag with metallic influences. Such caking is often referred to as a "bear" in specialist circles. The English technical term for this is converter skull.
    To check the converter vessel for contamination, the (empty) converter vessel is tilted forward in the prior art, so that the converter axis is oriented horizontally. In the further sequence, optical checks are then carried out or sensor systems are introduced into the converter opening. Such checks - be it by a human being or by sensor systems - are usually carried out while the converter vessel is empty, but remains heated up. The controls are therefore exhausting and also stress and strain possible sensor systems. Furthermore, these controls are also dangerous since the converter housing (dog house) has to be opened for the control of the converter vessel and the inspecting person has to stand in front of the converter vessel which is tilted forward. Furthermore, due to the fact that the converter vessel / 27
    201700013 must be tilted forward, due to the system, a check is only possible while the converter vessel is empty. Furthermore, due to the system, the control is only possible during a long process break that has to be scheduled in the production.
    The object of the present invention is to create possibilities by means of which the converter vessel can be checked for caking even during short process breaks - in particular during the process break between emptying the converter and refilling the converter in normal operation.
    The object is achieved by a probe with the features of claim 1. Advantageous embodiments of the probe are the subject of dependent claims 2 to 13.
    According to the invention, a probe of the type mentioned at the outset is designed such that for at least some of the penetration points, a respective vector, which is orthogonal to the transparent structure at the respective penetration point, has a radial component relative to the lance axis when the probe is connected to the sublance.
    In contrast to the probe of the JP document mentioned at the outset, the camera system of the present invention does not “look” to the front (onto the converter base), but to the side.
    It is possible that, for all penetration points, their respective orthogonal vector on the transparent structure not only has the radial component but also an axial component relative to the lance axis when the probe is connected to the sublance (a tangential component is often not useful). Preferably, however, for at least some of the penetration points, their respective orthogonal vector on the transparent structure, with the probe connected to the sublance, is oriented purely radially relative to the lance axis, thus not only points / 27
    201700013 no tangential component, but also no axial component.
    It is possible that the penetration points, the vector of which orthogonally on the transparent structure has a radial component when the probe is connected to the sublance, form an area which only partially revolves around the lance axis. In this case, for example, a camera can be used that looks directly "to the side" or actually looks forward, but whose field of vision is deflected to the side by a mirror. In the event that a surface is formed which only partially revolves around the lance axis, the camera in the probe or the sublance can preferably be rotated together with the probe and the camera around the lance axis.
    In a particularly preferred embodiment of the probe, the penetration points, the vector of which orthogonally on the transparent structure has a radial component when the probe is connected to the sublance, form on the transparent structure an at least substantially annular surface around the lance axis. It can therefore be seen as an all-round view. Corresponding camera systems are known. For example, there are corresponding imaging optics (fisheye lens), panoramic cameras and omnidirectional cameras (so-called 360 ° cameras). It is also possible to use several cameras, each of which covers only a partial area around the lance axis, but together covers the full angular area around the lance axis.
    The transparent structure is preferably made of quartz glass. Alternatively or additionally, special coatings can be used that reduce infrared radiation. This means that the transparent structure can withstand the thermal loads to which it is exposed.
    / 27
    201700013
    In many cases, the probe has a front and a rear end structure, the probe being connectable to the sublance in the area of the rear end structure. In this case, the front end structure can be connected to the rear end structure in particular via a plurality of rods running parallel to the lance axis when the probe is connected to the sublance. The number of bars is usually two, three or four. The bars can be made of steel.
    In individual cases, the rods can be arranged outside a volume enclosed by the transparent structure. As a rule, however, they are arranged within this volume.
    In a particularly preferred embodiment of the present invention, the probe is optically opaque at its front end structure. As a result, the protection of the probe and in particular of the camera system can be optimized, in particular regardless of the optical properties.
    It is possible that the images are led outside as they are captured by the probe. Alternatively, an intelligence for preprocessing or complete processing of the images captured by the camera system can be arranged in the probe.
    In a particularly preferred embodiment, the camera system has at least one camera which is designed in such a way that it captures a sequence of images at an image rate which is considerably greater than 24 images per second. The frame rate can in particular be at least 96 frames per second, for example 120 frames per second. This makes it possible to minimize the acquisition period during which the probe is in the (empty, but hot) converter. The captured images can be reproduced as required at the same frequency as they were captured or at a different frequency, in particular / 27
    201700013 with a lower frequency. It is even possible to display the images individually and to switch them through or to scan them manually.
    The signal transmission from the camera system to an evaluation device arranged outside the probe can be wired or wireless as required. In the case of wired transmission in particular, transmission can take place via the standardized interface of the sublance.
    It is possible that the camera system is designed as a purely optical camera system (designed for light in the visible range). However, the camera system preferably has at least one camera which is designed as a thermal imaging camera. This enables particularly simple and reliable image acquisition.
    The probe preferably has a gas supply, by means of which a gas can be supplied to the probe which flows around the camera system. This makes it possible to cool the camera system. Alternatively, if required, the gas can only be supplied and discharged from the probe into the converter vessel or returned via its own return line.
    The object is further achieved by a sublance of a converter vessel with the features of claim 14. According to the invention, the sublance is connected to a probe according to the invention, in particular the probe is plugged onto the sublance.
    The object is further achieved by the use of a probe according to the invention connected to a sublance for the detection of deposits of slag on the converter vessel, in particular on the converter mouth.
    A probe is normally attached to the sublance, by means of which only / or at least among others the / 27
    201700013
    Temperature of the molten metal in the converter vessel is detected. The associated evaluation system for signals detected by means of a probe, which is connected to a sublance of a converter vessel during the detection of the signals, generally has a multi-pole receptacle arranged in the sublance for contacting the probe and an evaluation device for evaluating the detected signals, wherein the evaluation device is arranged at a distance from the sublance and the converter vessel.
    In order to be able to use the sublance both for the “normal” temperature measurement and for the acquisition and evaluation of images according to the invention, this evaluation system is preferably designed in such a way that
    that the receptacle is connected to a switching device via common sections of connecting lines,
    the switchover device is connected to a first sub-device of the evaluation device via first separate sections of the connecting lines and is connected to a second sub-device of the evaluation device via second separate sections of the connecting lines,
    - That by means of the switching device, depending on the switching state of the switching device, either the first own sections of the connecting lines or the second own sections of the connecting lines can be connected to the common line sections of the connecting lines and
    - That the first partial device is used to determine or evaluate at least one temperature recorded by the probe on the basis of the signals detected, and that an image recorded by the probe is determined or evaluated using the second partial device.
    As a result, the signals detected by the respective probe can be fed to the “correct” sub-device in a simple manner.
    / 27
    201700013
    As already mentioned, “normal” probes are usually used - at least among other things - to record temperature signals. In this case, at least the first separate sections of the connecting lines, via which the temperature signals are transmitted, each consist of the same material as the common sections of the connecting lines, to which they are connected in the corresponding switching state via the switching device.
    In the course of the temperature measurement and evaluation, signal falsifications that would result from a transition from one metal or one alloy to another metal or another alloy can thereby be avoided.

    Description of the embodiments / 27
    201700013
    1 to 3 show a probe 1 for a sublance 2 of a converter vessel 3 (see FIG. 4). The probe 1 can be connected to the sublance 2. For example, the probe 1, as indicated by an arrow 4 in FIG. 2, can be plugged onto the sublance 2 in the direction of a lance axis 5 of the sublance 2. Preferably, the probe 1 emits a “sign of life” immediately after being connected to the sublance 2. For example, a short visual or acoustic message can be given. A purely signaling message can also occur, which a person cannot sense with his sensory organs without technical aids.
    In the state in which the probe 1 is connected to the sublance 2, the probe 1 is fixed to the sublance 2. Your position and orientation are therefore fixed. The following explanations always refer to this state, that is to say the state in which the probe 1 is connected to the sublance 2.
    Insofar as the terms “axial”, “radial” and “tangential” are used below, they are always related to the lance axis 5. “Axial” is a direction parallel to the lance axis 5. “Radial” is a direction orthogonal to the lance axis 5 towards or away from the lance axis 5. "Tangential" is a direction that is orthogonal to both the axial and radial directions. "Tangential" is therefore a direction which, with a constant axial position and at a constant radial distance from the lance axis 5, is directed in a circle around the lance axis 5.
    When connecting the probe 1 to the sublance 2, there is usually not only a purely mechanical connection, but also an electrical contact. For example, the sublance 2 usually has a multipole receptacle 6, into which a corresponding multipole plug pin 7 of the probe 1 can be inserted — this also applies to probe 1 according to the invention. The number of poles of the receptacle 6 and the plug pin 7 is usually in / 27
    201700013 digit range, for example with six Poles. However, receptacles 6 and connector pins 7 with more than 10 poles are also known, in particular with 12 poles.
    The probe 1 has a camera system 8. The camera system 8 is shielded from the surroundings of the sublance 2 by means of a transparent structure 9. The transparent structure 9 can consist of quartz glass, for example. Alternatively or additionally, the transparent structure 9 can be coated with at least one layer that absorbs infrared radiation.
    At least one image B can be captured by means of the camera system 8. As a rule, multiple images B can even be captured by means of the camera system 8. According to the illustration in FIG. 5, it applies to each image B that it is a two-dimensional arrangement of pixels P. Each image B thus has a large number of pixels P or pixels P. Each pixel P represents an image of a location P 'from the surroundings of the camera system 8.
    It is possible that, for some of the pixels P, the imaged location P 'originates from the surroundings of the camera system 8, but lies within the probe 1. For example, the probe 1 can have a front and a rear end structure 10, 11 as viewed in the direction of the lance axis 5, as shown in FIGS. 1 and 2. In this case, the probe 1 can be connected to the sublance 2 in the region of the rear end structure 11. In this case, the front end structure 10 is connected to the rear end structure 11. The connection can be made, for example, via rods 12 running parallel to the lance axis 5. The number of bars 12 is usually two, three or four. The material of the rods 12 can be steel, for example. The rods 12 can in particular be arranged within a volume enclosed by the transparent structure 9. The camera system 8 is generally connected to the rear end structure 11. If the camera system / 27
    201700013 system 8 also detects the area in the direction of the lance axis 5 and the front termination structure 10 is optically opaque, only the front termination structure 10 is imaged in this part of the detection area, but not an area outside the probe 1.
    In the context of the present invention, this is the fact that, for some of the image points P, the imaged location P 'may originate from the surroundings of the camera system 8, but lies within the probe 1 - but is of secondary importance. It is crucial that at least for a portion of the pixels P the imaged location P 'not only comes from the area surrounding the camera system 8, but also lies outside the probe 1. These pixels P thus each represent an image of a location P 'from the surroundings of the sublance 2. For these pixels P, a respective connecting line 13 from the respective image point P to the respectively depicted location P' from the surroundings of the sublance 2 penetrates the transparent structure 9 at a respective penetration point 14.
    The transparent structure 9 generally has a uniform thickness d and is otherwise flat. For each penetration point 14 there is therefore a respective vector 15 which is oriented normal to the transparent structure 9, i.e. stands orthogonally on the transparent structure 9, clearly determined. The vector 15 can have a radial component, an axial component and a tangential component. This can be the case, for example, if the transparent structure 9 is designed as a relatively small viewing window, by means of which viewing in the tangential direction allows only a relatively small area. In many cases, however, the transparent structure 9 is rotationally symmetrical about the lance axis 5. In this case, the tangential component is not present or has the value 0.
    / 27
    201700013
    According to the invention, the transparent structure 9 surrounds the camera system 8 at a radial distance. At least for some of the penetration points 14, the respective vector 15 has a radial component relative to the lance axis 5.
    The detection range of the camera system 8 extends over a polar angle α (see FIG. 2) and an azimuth angle β (see FIG. 3). The polar angle α and the azimuth angle β are related to a cylindrical coordinate system, the axis of symmetry of which is identical to the lance axis 5. The origin of this coordinate system on the lance axis 5 can be determined suitably and, for example, coincide with the location of the camera system 8.
    In the following, only the polar angle α is dealt with first.
    Depending on the design of the probe 1, it is possible that the vector 15 is not oriented exclusively radially for any of the penetration points 14. For example, the transparent structure 9 can have a hemispherical shape and surround the camera system 8 in this form. In such a case, if the camera system 8 is arranged in the center of the transparent structure 9, the direction of the connecting line 13 is identical to the direction of the vector 15 for each penetration point 14. If in such a case the detection range of the camera system 8 is still smaller than a hemisphere, ie the polar angle α of the detection range is smaller than 180 °, each vector 15 also has an axial component in addition to the radial component. On the other hand, if in such a case the detection range of the camera system 8 is a hemisphere or is even larger than a hemisphere, there are also vectors 15 which are oriented purely radially relative to the lance axis 5. Such camera systems 8 are also well known to experts. For example, so-called fisheye lenses can have a detection area that is larger than a hemisphere.
    / 27
    201700013
    According to the preferred embodiment shown in FIGS. 1 to 3, however, the transparent structure 9 is cylindrical. In this case, the respective vector 15 is oriented purely radially relative to the lance axis 5 not only for a part, but even for all penetration points 14.
    So far, the detection range of the camera system 8 has been considered in connection with FIGS. 1 and 2 in an axial plane. The detection area of the camera system 8 is now considered in a radial plane in conjunction with FIGS. 1 to 3.
    Regardless of its concrete size, the polar angle α has a certain value. The penetration points 14 therefore extend in axial direction over a certain length l. Furthermore, the azimuth angle β also has a certain value. The penetration points 14 therefore extend in the tangential direction over the azimuth angle β. The penetration points 14 therefore form a surface independently of the concrete values of polar angle α and azimuth angle β. It is possible for some camera systems 8 that the penetration points 14, whose vector 15 orthogonally on the transparent structure 9 has a radial component, form a surface that only partially revolves around the lance axis 5. For example, the camera system 8 can have a single camera with a “conventional” detection area, the optical axis of the camera coinciding with the lance axis 5, but the imaging takes place via a mirror oriented at an angle. In this case, the sublance 2 can preferably be rotated as a whole or the mirror can be rotated.
    The penetration points 14, the associated vector 15 of which preferably have a radial component, form on the transparent structure 9, however, an at least substantially annular surface around the lance axis 5. An exception can be, for example, that in Azimuth / 27
    201700013 direction small angular ranges covered by the rods 12. Such camera systems 8, which enable all-round detection in the azimuth direction over 360 °, are known to those skilled in the art.
    An evaluation device 16 is arranged outside the probe 1. The images B are transmitted from the camera system 8 to the evaluation device 16. The signal transmission from the probe 1 or the camera system 8 to the evaluation device 16 can alternatively (see FIG. 6) be wired or (see FIG. 7) be wireless. It is possible that only those components are arranged in the probe 1 that are necessary for the acquisition of the images B as such. In this case, the images B are transmitted to the evaluation device 16 as they are captured. However, an intelligence 17 is preferably arranged in the probe 1, by means of which the images B captured by the camera system 8 are preprocessed or completely processed before being transmitted to the evaluation device 16. Temporary storage is also possible.
    The camera system 8 itself can be designed as required. For example, the camera system 8 can have a camera, which - similar to a photo camera - captures a single image B only upon corresponding triggering. Alternatively, the camera system 8 can have at least one camera, which - similar to a film camera - continuously captures an image B again and again, in total thus a sequence of images B. The frame rate, that is the number of images B captured per second, can be as required be determined. However, the images B are preferably captured at an image rate that is considerably greater than 24 images per second. The frame rate can in particular be at least 96 frames per second, for example 120 frames per second. This embodiment has the advantage that the - relatively sensitive - probe 1 can be moved into the converter vessel 3 at high speed and then quickly moved out of the converter vessel 3 again. The time during which the / 27
    201700013
    Probe 1 is subjected to high thermal stress, can therefore be kept low. The images can alternatively be displayed in real time or at a later time. In the case of a reproduction at a later point in time, the reproduction of the images B can alternatively take place at the frame rate at which the images B were taken or at a slower rate. Individual images B can also be reproduced. Alternatively or additionally, it is also possible for the camera system 8 to have at least one camera which is designed as a thermal imaging camera. In the present case, thermographic images can be evaluated particularly efficiently.
    To reduce the thermal load on the camera system, the probe 1 can also have a gas supply 18 (see FIG. 2). In this case, a gas 19 can be supplied to the probe 1 by means of the gas supply 18, which flows around the camera system 8 and thereby cools it. In individual cases, it may be possible to release the gas 19 directly into the environment, for example via a spring-loaded valve. However, a gas recirculation 20 is preferably also present.
    The supply of the gas supply 18 with the gas 19 and possibly also the removal of the gas 19 from the gas recirculation 20 can take place via corresponding lines 21 of the sublance 2. Such lines 21 are usually present in the sublance 2.
    The probe 1 or the sublance 2, including the probe 1 connected to the sublance 2, is preferably used for the detection of deposits 22 of slag on the converter vessel 3, in particular for the detection of deposits 22 on the converter mouth 23. For this purpose, when the converter vessel 3 is empty, the probe 1 according to the invention connected to the sublance 2 and then inserted vertically into the converter vessel 3. After the retraction, however, the probe 1 is retracted immediately or immediately thereafter. During the retraction and / or during the retraction, the images B are captured by the camera system 8. It is possible to insert the probe 1 deep into the converter vessel 3. In the Re / 27
    201700013 gel, however, it is entirely sufficient to insert the probe 1 only slightly into the converter vessel 3. For example, typical converter vessels 3 - see FIG. 4 - have a cone area 24 which extends in the vertical direction over a height h of several meters. As a rule, it is only necessary to move the probe 1 into the converter vessel 3 over a range of, for example, a maximum of 50% of the cone region 24, for example over approximately 0.5 m.
    The present invention has many advantages. In particular, it is possible in a simple manner to recognize deposits 22 of slag (“bears”) early and comprehensively. Nevertheless, the probe 1 can be manufactured simply and inexpensively. Due to the shortness of the high thermal load, the probe 1 can be made reusable and can have a long service life in this case.
    Although the invention has been illustrated and described in detail by the preferred exemplary embodiment, the invention is not restricted by the disclosed examples and other variants can be derived therefrom by a person skilled in the art without departing from the scope of protection of the invention.
