    description
    Stirring coil arrangement in a continuous caster
    The present invention is based on a stirring coil arrangement in a continuous casting installation, by means of which a metal strand is cast in a casting direction, the metal strand extending across a width in a width direction and a thickness in a thickness direction, orthogonal to the casting direction,
    the stirring coil arrangement has a plurality of stirring coils,
    - The stirring coils each have a winding which rotates about a respective winding axis and which is acted upon by a respective alternating current during operation of the stirring coil arrangement.
    The present invention is further based on a continuous casting installation, by means of which a metal strand is cast in a casting direction, the metal strand extending across a width in a width direction and a thickness in a thickness direction, orthogonally to the casting direction,
    the continuous caster has a strand guide with a plurality of strand guide rollers,
    the strand guide rollers have axes of rotation running parallel to the width direction and are set against the metal strand,
    - The continuous caster has a stirring coil arrangement of the type mentioned.
    Such stirring coil arrangements are generally known. They are used in particular in the continuous casting of steel to influence the formation of the metallurgical structure in the solidification area of the metal strand. They generate corresponding (liquid) flows in the area of the not yet solidified metal strand by means of magnetic fields that change over time and location. This affects crystal growth. This leads to a desired globu2 / 20
    201600235 literal solidification of the metal strand. For this purpose, the stirring coils are generally loaded with the individual phases of a multi-phase three-phase system. The number of phases is usually three.
    A high magnetic flux density is required to generate the desired (liquid) flows. High coil currents are therefore required in order to produce the necessary eddy currents in the area of the metal strand which has not yet solidified, which in turn produce sufficiently high flow velocities in the liquid area of the metal strand.
    The magnetic flux density depends to a considerable extent on the distance between the stirring coils and the stirring area, the stirring area being approximately 50-100 mm from the strand surface in the thickness direction. In particular, the magnetic flux density is approximately inversely proportional to the square of the distance. The closer the stirring coil arrangement can be arranged to the metal strand, the better the stirring effect and the less electricity is required to ensure good stirring performance.
    This advantage in terms of distance is exploited by means of so-called stirring rollers. In the case of stirring rollers of this type, the stirring coils are built into the strand guide rollers. This allows the distance to the surface of the strand to be kept very small. The distance to the strand surface is usually in the range of approx. 40-50 mm. Advantages of this configuration are the lower stirring currents with a simple construction of the coils. One disadvantage is the number of stirring rollers required per system. Four rollers per bending zone are required for a good stirring effect. Bending zones are changing parts and therefore available in the appropriate quantity (approx. Three pieces per casting thickness and strand). So you need 12 stirring rollers for a strand with a casting thickness. The roller constructions around the stationary stirring coil are still wear parts that have to be repaired regularly. The roll material must be anti-magnetic, corrosion-resistant, wear-resistant and a good warm 3/20
    201600235 have strength. A high-temperature steel with a high chromium and nickel content is used, with an austenitic structure, carbides and intermetallic phases and a hard chrome coating to minimize surface wear. Such steel costs about 25 times more than steel commonly used for strand guide rolls.
    Because the usual intermediate roller supports are missing, a larger roller diameter is still required in order to be able to transmit the occurring forces. In order to accommodate a corresponding spool inside the reel, the usual reel diameter must therefore be increased from around 150 mm to around 240 300 mm. Because of the larger roll diameters, however, larger distances between the rolls are required. The stirring rollers therefore have a poorer supporting effect on the not yet solidified, hot and soft strand due to the larger roller spacings. Bulging and pushing back the strand shell can lead to undesirable internal cracks. Bulging effects can also occur to an increased extent.
    So-called box-type stirrers are known as an alternative embodiment to the stirring rollers. Here the stirring coils are not arranged in the strand guide rollers, but are positioned behind the strand guide rollers. The stirring coils are combined in a water-cooled box and fastened on a sliding trolley. The trolley allows entry into a working position and extension into a maintenance and changing position. In the maintenance and changing position, the bending zone or the strand guide segments can be changed without having to remove the stirrer. This means that not every bending zone or segment has to be equipped with its own stirrer. The maintenance costs are therefore considerably lower than with stirring rollers.
    The disadvantage of the box-type stirrer is the greater distance between the stirring coil arrangement and the surface of the strand. The distance is often in the range of approx. 230-260 mm. In comparison is / 20
    201600235 the distance for the stirring roller is only 40-50 mm. To produce the same stirring effect, a box-type stirrer therefore requires a considerably greater electrical output than a design with stirring rollers. This has a negative impact on operating costs. Furthermore, due to the higher required electrical power of the box-type stirrer, there is also more heat loss. The power loss must be dissipated by water cooling.
    In the prior art, strand guide rollers are also used in the case of a box-type stirrer which, as seen in the width direction, are supported only on the outside but have no intermediate supports. Even with a box-type stirrer, the strand guide rollers must therefore have an enlarged roller diameter. The increase in diameter compared to the diameter of normal strand guide rollers is not quite as large as that of agitator rollers, but it is still considerable. From the approach, however, there are the same disadvantages that have already been mentioned above in connection with stirring rollers.
    The object of the present invention is to design a stirring coil arrangement of the type mentioned at the outset such that the cast metal strand can also be supported in the region of the stirring coil arrangement by means of a segmented strand guide roller (that is to say a strand guide roller which is divided in the direction of its axis of rotation).
    The object is achieved by a stirring coil arrangement with the features of claim 1. Advantageous embodiments of the stirring coil arrangement are the subject of dependent claims 2 to 4.
    According to the invention, a stirring coil arrangement of the type mentioned at the outset is designed
    - That the winding axes of the stirring coils are oriented orthogonally to the width direction and / 20
    201600235
    - That the stirring coils are arranged side by side as seen in the width direction and have a distance from one another as viewed in the width direction.
    This configuration creates a box-type stirrer in which an intermediate support can be arranged in the area between two stirring coils due to the spacing of the stirring coils in the width direction. It is therefore possible that the stirring coil arrangement is arranged in the region of at least one strand guide roller, and that the at least one strand guide roller not only seen in the width direction
    - As in the prior art - at its two ends, but also between the two ends at several points on supports and that the stirring coils are arranged between the supports when viewed in the width direction.
    In a preferred embodiment, the stirring coil arrangement has an iron core. The iron core in turn has a yoke that extends across all the stirring coils when viewed in the width direction. Extenders extend from the yoke to the metal strand, each of which dips into one of the stirring coils.
    The stirring coil arrangement preferably has a positioning device, by means of which the stirring coils can be moved in between the supports and can be moved out of the area between the supports.
    The object is further achieved by a continuous caster with the features of claim 5. According to the invention, a continuous caster of the type mentioned at the outset has a stirring coil arrangement according to the invention. Furthermore, the strand guide rollers in the area of the stirring coil arrangement have at least approximately the same diameter as the strand guide rollers outside this area.

    The above-described properties, features and advantages of this invention and the manner in which they are achieved can be more clearly understood in connection with the following description of the exemplary embodiments, which are explained in more detail in conjunction with the drawings. The following are shown in a schematic representation:
    1 shows a continuous caster from the side,
    2 shows a section of FIG. 1,
    3 shows a top view of a strand guide roller and a stirring coil arrangement and
    4 shows the strand guide roller and the stirring coil arrangement from FIG. 3 from a direction IV-IV in FIG. 3.
    The figures are explained together below.
    A metal strand 1 is cast by means of a continuous caster. The metal strand 1 can be made of steel, for example. To cast the metal strand 1, liquid metal 2 is poured into a continuous casting mold 3 and then withdrawn from the continuous casting mold 3. A strand guide 4, which has a multiplicity of strand guide rollers 5, is arranged below the continuous casting mold 3. The metal strand 1 is supported and guided by means of the strand guide rollers 5. The distance between the strand guide rollers 5 from one another is shown in an exaggerated manner in the figures. In practice, the strand guide rollers 5 follow one another closely.
    The casting in the continuous casting mold 3 takes place in a casting direction x. The pouring direction x is usually initially directed vertically from top to bottom. However, the pouring direction x can also form an angle with the vertical that is different from 0 °. Often the metal strand 1 continues to be deflected gradually in an arc into the horizontal after exiting the continuous casting mold 3. The pouring direction x follows this movement. The casting direction x is therefore not rigid and unchangeable the direction in which the metal strand 1 leaves the continuous casting mold 3, but dy7 / 20
    201600235 Namely the direction in which the cast metal strand 1 moves at its respective location.
    The metal strand 1 has not yet solidified when it leaves the continuous casting mold 3. It therefore has a strand shell 1 'and a still liquid core 1 ". The metal strand 1 extends orthogonally to the casting direction x, viewed in a width direction over a width b and in a thickness direction over a thickness d. The width b is larger than the thickness d. As a rule, a ratio of width b to thickness d is above 2: 1. The strand guide rollers 5 are employed on the broad side of the metal strand 1 on the metal strand 1. Their axes of rotation therefore run parallel to the width direction.
    The continuous caster also has a stirring coil arrangement 6. The stirring coil arrangement 6 can be water-cooled as required. Alternatively, however, it can also be air-cooled.
    The stirring coil arrangement 6 has a plurality of stirring coils 7. The stirring coils 7 are acted upon by a respective alternating current during operation of the stirring coil arrangement 6, if flows are to be generated in the liquid core 1 “by means of the stirring coil arrangement 6. As a rule, the alternating currents with which the stirring coils 7 are applied form the phases L1, L2, L3 (N = neutral conductor) of a three-phase system. Furthermore, the three-phase system generally has three phases L1, L2, L3, so that there are also three stirring coils 7. However, the present invention is not limited to configurations with three stirring coils 7. There can also be four or five stirring coils 7. Under certain circumstances, it may be necessary in this case to feed the stirring coils 7 from a three-phase system with a different number of phases, for example from a three-phase system with two, four or five phases.
    The stirring coils 7 each have a winding 8. The respective winding 8 runs around a respective winding axis 9.
    / 20th
    201600235
    The winding axes 9 of the stirring coils 7 are oriented orthogonally to the width direction. The winding axes 9 are further oriented at a noteworthy angle to the (local) casting direction x - as a rule uniform for all winding axes 9. The angle should be as close as possible to 90 °. Ideally, it is exactly 90 °. Slight deviations are possible.
    The stirring coil arrangement 6 (and with it the stirring coils 7) is arranged in the region of at least one strand guide roller 5. The at least one strand guide roller 5 is viewed in the width direction at its two ends in end bearings 10. Forces exerted by the metal strand 1 on the at least one strand guide roller 5 are thus diverted via the end bearings 10 into corresponding supports 11. Furthermore, the stirring coils 7 are arranged side by side as seen in the width direction. However, they do not adjoin one another in the width direction, but are at a distance a from one another in the width direction. This configuration - namely the spacing a of the stirring coils 7 from one another - enables the at least one strand guide roller 5 to be additionally mounted in intermediate bearings 12 between the two ends. Forces exerted by the metal strand 1 on the at least one strand guide roller 5 are thus derived not only via the end bearings 10 in their supports 11, but also additionally via the intermediate bearings 12 into corresponding supports 13. This applies, although during operation of the stirring coil arrangement 6, the stirring coils 7 in Seen width direction are arranged between the supports 11, 13.
    The number of intermediate stores 12 can be determined as required. In an embodiment with three stirring coils 7, there are generally two intermediate bearings 12. In individual cases, however, it is also possible for only a single intermediate storage 12 to be present. With - for example - four stirring coils 7, either a single intermediate bearing 12 or three intermediate bearings 12 are present.
    / 20th
    201600235
    As a rule, the stirring coil arrangement 6 has an iron core 14. The iron core 14 has a yoke 14 '. The yoke 14 ′ extends over all stirring coils 7, as seen in the width direction. From the yoke 14 ′, extensions 14 ″ extend toward the metal strand 1. The runners 14 ″ immerse in one of the stirring coils 7.
    As a rule, the stirring coil arrangement 6 can be set against the metal strand 1 or the strand guide rollers 5 there. The stirring coil arrangement 6 therefore generally has a positioning device 15, by means of which the stirring coils 7 can be moved in between the supports 11, 13 and can be moved out of the area between the supports 11, 13. The positioning device 15 can be designed, for example, as a carriage 16 which can be moved on a corresponding running surface 17 via wheels. Alternatively or additionally, it is possible, for example, to move the stirring coil arrangement 6 along a linear guide by means of a hydraulic cylinder unit.
    The strand guide rollers 5 outside the range of
    Stirring coil arrangement 6 have a diameter D1 which is generally in the range between 120 and 200 mm, for example approximately 140 mm to 160 mm. The strand guide rollers 5 in the region of the stirring coil arrangement 6 can have a diameter D2 which - at least approximately, for example to within ± 10% - is equal to the diameter D1 of the strand guide rollers 5 which are arranged outside this region.
    In summary, the present invention thus relates to the following facts:
    A metal casting 1 is cast in a casting direction x by means of a continuous caster. The metal strand 1 extends in a width direction over a width b and in a thickness direction over a thickness d. A stirring coil arrangement 6 in the continuous casting installation has a plurality of stirring coils 7. The / 20
    201600235
    Stirring coils 7 each have a winding 8 which rotates about a respective winding axis 9 and which is acted upon by a respective alternating current during operation of the stirring coil arrangement 6. The winding axes 9 of the stirring coils 7 are oriented orthogonally to the width direction. The stirring coils 7 are arranged side by side as viewed in the width direction. As seen in the width direction, they are at a distance a from one another.
    The present invention has many advantages. In particular, the magnetic stray field losses can be reduced by the inventive design of the stirring coil arrangement 6. Furthermore, the electrical connected load of the stirring coil arrangement 6 can be reduced to approximately half compared to a stirring coil arrangement of the prior art. By reducing the diameter D2 of the strand guide rollers 5 in the area of the stirring coil arrangement to the usual size, the risk of internal cracks in the metal strand 1 can be significantly reduced. Bulging effects are also reduced. Interference from other electrical and in particular electronic components (for example sensors) caused by the electromagnetic stray fields is reduced. The steel required for the strand guide rollers 5 in the area of the stirring coil arrangement 6 can be the usual austenitic, stainless steel that is also used for strand guide rollers 5. The use of special steel is not necessary. As a result, the advantages of a design with stirring rollers can be implemented with the advantages of the box-type stirrer.
    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 variations can be derived therefrom by a person skilled in the art without departing from the scope of protection of the invention.
