Definitions

  • the invention relates to a device for heating a metal strip and to apparatuses, equipped with a device of this type, for producing hot-rolled metal strip.
  • a particularly critical drop in temperature occurs during what is known as Steckel rolling, as during reversing the respective strip end is not jointly heated in the coilbox.
  • the procedural flexibility is crucially dependent on the possibility of a purposeful adjustability of the strip temperature in order to produce a required product mix, including different process parameters (casting rate, degree of deformation, etc), resulting from the need for different steel qualities or strip thicknesses.
  • a further problem in the production of hot-rolled metal strips consists in the fact that a non-uniform temperature distribution occurs over the cross section of the stock to be hot-rolled. This inhomogeneity may lead, on the one hand, to unflat or askew strips, owing to locally varying flow properties, and, on the other hand, to a non-uniform structure formation. In principle, a non-ideal initial thickness profile (inconstancies) may also cause the above-mentioned unflat or askew strips during hot-rolling, despite the uniform temperature distribution over the strip cross section.
  • the advantage of using an induction furnace for heating or warming the stock to be rolled consists in the fact that the rolling stock may be heated to a relatively precisely predeterminable temperature in a short application time.
  • induction furnaces that had, in the past, been provided for this purpose did not yield results that satisfied the increasingly stringent requirements.
  • the space available in the entry region of the hot-rolling stand was frequently insufficient for fitting a conventional furnace.
  • the overall size of conventional continuous furnaces means that there has to be a considerable distance between the outlet of the furnace and the entry region of the hot-rolling stand, so the strip leaving the furnace is again exposed to cooling on its path to the rolling stand.
  • Step rolling stands such as are disclosed, for example, in DE 195 81 737 T1
  • the strip which is hot-rolled to a specific thickness, is reeled between each rolling step in a furnace, in which it is then maintained at a high temperature, which is optimal for carrying out the following rolling pass.
  • the object of the invention was to provide a device for heating a metal strip, which device allows the metal strip to be heated precisely and rapidly to a predetermined temperature, while taking up little space.
  • Apparatuses of the above-described type that are intended for producing hot-rolled metal strip, with which apparatuses, despite the small overall space available, optimal heating, in terms of the hot-rolling process, of the rolling stock may be carried out, were also to be specified. This includes the compensation of problems during hot-rolling resulting from the thickness profile, which problems may result in unflat or askew strips.
  • a device of this type is equipped, according to the invention, with an inductively operating heating devices, each of which comprises an inductor inducing an electromagnetic field, which inductor extends over the conveying path of the metal strip to be heated and the position of which is adjustable transversely to the conveying path depending on of the width of the metal strip.
  • the invention provides at least one heating device, which carries an inductor.
  • This inductor extends, in each case, in the transverse direction over the transportation path, through which the rolling stock to be heated passes. During its transportation, the rolling stock therefore passes through the electromagnetic field generated by the inductor, which field causes a concentrated heating of the rolling stock.
  • the inductor of the heating device is adjustable transversely to the conveying direction of the metal strip to be heated. This transverse adjustability allows the position of the inductor to be optimally adapted, in each case, to the course and the width of the metal strip.
  • the invention therefore provides a transverse field heating device that allows concentrated heating of a metal strip to a desired temperature within very short application times, while taking up as little space as is conceivable.
  • the device according to the invention is particularly suitable for heating steel strips that are hot-rolled immediately after the reheating process.
  • a device according to the invention may therefore be arranged in immediate proximity to a rolling stand, so the temperature losses between the heating process and the hot-rolling process are reduced to a minimum.
  • a particular advantage of the invention consists in the fact that the precise adjustability of the temperature characteristic allows, as a result of the adjustment of a specific temperature profile over the width of the strip to the rolled, equally specific deformation properties to be adjusted during the rolling process.
  • the predetermined temperature characteristic thus allows unflat strips, directional stability and other geometrical defects of the strip to be minimised, without requiring expensive additional measures or devices.
  • a configuration of the invention that has in practice proven particularly advantageous is characterised in that it is equipped with at least two inductively operating heating devices arranged in pairs.
  • the heating devices each carry an inductor.
  • a paired arrangement of this type allows increased quantities of heat to be introduced into the rolling stock.
  • the transverse field generated by said inductors may be configured in such a way that it always reliably encompasses the entire width of the strip to be heated.
  • the inductors carry metal sheets, which influence the orientation and extent of the electromagnetic field generated by the inductors.
  • the transverse field may, for example, if required be configured in such a way that a desired overheating occurs in the region of the strip edges.
  • the metal sheets may also be oriented in such a way that a higher temperature is generated in the region of the strip centre than in the edge regions. It is not necessary to change the metal sheets for each application; rather, the intensity with which the field, which is influenced by the metal sheets, acts on the stock to be heated may in turn be varied by means of a transverse adjustment of the inductors.
  • a particularly practical configuration of the invention is characterised in that it comprises at least four heating devices. These four heating devices may be arranged in pairs opposing one another in such a way that the heating devices are arranged in alternation laterally of one side and of the other side of the conveying path in the conveying direction of the metal strip. In the case of this arrangement of the heating devices, a particularly uniform effect of the transverse fields induced by the inductors on the stock to be heated is achieved.
  • a first heating device is positioned laterally of one side, two heating devices are positioned laterally of the other side, and the fourth heating device is positioned laterally of the side of the transportation path with which the first heating device is associated.
  • Heating devices comprise a respective converter and in that the converters of all of the heating devices are in forced synchronisation.
  • the surface of rolls on which the metal strip passes, for example, on its route through the device according to the invention may in this way be protected from damage. This protection may be additionally improved by means of suitable insulation measures, as a result of which an undesired current flow is prevented.
  • a further fundamental point for the effect of the device according to the invention is the configuration of the respectively used inductors or the heat conductors thereof. It has thus proven beneficial in practical tests if, in a plan view of the conveying path, the inductors exhibit an elongate, rectangular shape.
  • the heat conductors thereof may be arranged in such a way that they cover a large surface extending parallel to the transportation path of the metal strip.
  • the inductors of the heating devices used according to the invention comprise a respective heat conductor, which comprises a first longitudinal portion, which, starting from a connection portion, extends along the outside of one longitudinal side of the respective inductor, a second longitudinal portion, which extends along the outside of the other longitudinal side, a third longitudinal portion, which extends along the inside of the first longitudinal portion, a fourth longitudinal portion, which extends along the inside of the second longitudinal portion and is connected to a second connection portion, a first short portion, which externally connects the end of the first longitudinal portion that is remote from the connection portion to the end of the second longitudinal portion that opposes this end, a second short portion, which connects the other end of the second longitudinal portion to the end of the third longitudinal portion that opposes it, and a third short portion, which internally connects the other end of the third longitudinal portion to the end of the fourth longitudinal portion that opposes it.
  • connection portions and the second short portion should preferably be arranged parallel to one another. It has also proven beneficial if the first and the third short portions are curved in their configuration, so an optimal effect of the electromagnetic field generated is also achieved in the region of the free end of the heat conductor formed by the relevant portions.
  • the device according to the invention is particularly suitable for heating cast strip, which, after the casting process, is hot-rolled to its final thickness in a hot-rolling stand.
  • the abovementioned object is therefore achieved in that it comprises a device for casting a molten metal to form a cast metal strip, a device for hot-rolling the cast metal strip and a device, which is arranged between the device for casting and the device for hot-rolling and is configured according to the invention, for reheating the cast strip prior to the hot-rolling process.
  • the device according to the invention may also be used in an apparatus for hot-rolling, carried out in a reversing manner, of a metal strip, which apparatus is equipped with a reversing rolling stand and with at least one device configured according to the invention, which device is arranged on one of the entry/exit sides of the reversing rolling stand and by which the stock to be hot-rolled is reheated prior to a rolling pass.

  • FIG. 2 is a schematic plan view of a device, used in the apparatus shown in FIG. 1 , for heating the cast strip;
  • FIG. 3 is a schematic plan view of an alternative configuration of the device, used in the apparatus shown in FIG. 1 , for heating the cast strip;
  • FIG. 4 is a diagram showing, for various operating tests, the temperature profile determined, in each case, in the cast strip prior to entry into the hot-rolling stand of the apparatus.
  • the apparatus 1 for producing hot-rolled steel strip 2 from cast strip 3 comprises, in succession in the conveying direction F of the cast strip 3 , a casting device 4 for casting a molten metal 5 to form the cast strip 3 , a rolling unit 6 for guiding the cast strip 3 , a device 7 for reheating the cast strip 3 , a rolling stand 8 for hot-rolling the cast strip 3 to form the steel strip 2 , and a roller table 9 , via which the steel strip 2 passes to a reeling device (not shown).
  • the casting device 4 is constructed in the manner of a conventional double roller known from the prior art.
  • the rolling unit 6 and the rolling stand 8 are also configured in a manner known per se.
  • the device 7 for heating the cast strip 3 which is conveyed to the rolling stand 8 , is equipped with four heating devices 10 , 11 , 12 , 13 of substantially identical construction.

  • a corresponding inductor 14 a , 15 a , 16 a , 17 a extends, in each case, in an identical manner transversely to the lower side of the conveying path 18 , so the strip 2 passes, in each case, through a coupling gap K formed between the inductors 14 , 14 a , 15 , 15 a , 16 , 16 a , 17 , 17 a.
  • the inductors 14 to 17 a are each equipped with a heat conductor 19 , the course and arrangement of which are selected in such a way that an electromagnetic transverse field, which is optimised with respect to its effect on the strip 3 to be heated passing under the inductors 14 to 17 a , is generated.
  • the heat conductors 19 each have a first longitudinal portion 19 b , which, starting from a connection portion 19 a , extends along the outside of one longitudinal side L 1 of the respective inductor 14 to 17 a , a second longitudinal portion 19 c , which extends along the outside of the other longitudinal side L 2 of the inductor 14 to 17 a , a third longitudinal portion 19 d , which extends along the inside of the first longitudinal portion 19 b , and a fourth longitudinal portion 19 f , which extends along the inside of the second longitudinal portion 19 c and is connected to a second connection portion 19 e .
  • the end of the first longitudinal portion 19 b that is remote from the connection portion 19 a is connected to the end of the second longitudinal portion 19 c that opposes this end by means of a first short portion 19 g , which is externally arranged and outwardly curved, while the other end of the second longitudinal portion 19 c is connected to the end of the third longitudinal portion 19 d that opposes it by means of a second, straight short portion 19 h .
  • the other end of the third longitudinal portion 19 d is internally connected to the end of the fourth longitudinal portion 19 f that opposes it by means of a third short portion 19 i , which is guided in a curved manner in a curvature extending parallel to the curvature of the first short portion 19 g .
  • the connection portions 19 a , 19 e and the second short portion 19 h are arranged parallel to one another.
  • the individual portions of the respective heat conductors 19 are jointly arranged in a plane extending parallel to the conveying path 18 .
  • the coil end of the inductors 14 to 17 a which is arranged in the region of the housing of the respective heating device 10 to 13 , comprises metal sheets (not shown), by means of which the field generated by the inductors 14 to 17 a is controlled in such a way that optimal heating, in terms of the particular features of the respectively treated steel material, of the edges 3 a , 3 b of the cast strip 3 is achieved.
  • the inductors 14 , 14 a , 15 , 15 a , 16 , 16 a , 17 , 17 a of each heating device 10 to 13 are carried, in each case, by the piston of an actuating cylinder 20 , which, as illustrated for the heating device 10 by means of broken lines, is arranged in the housing of the heating devices 10 , 11 , 12 , 13 .
  • the actuating cylinders 20 perform, in each case, independently of one another a linear actuating movement, directed transversely to the conveying path 18 , by means of which movement the position of the inductor pairs 14 , 14 a , 15 , 15 a , 16 , 16 a and 17 , 17 a , respectively associated with said cylinders, of the heating devices 10 to 13 is adjusted above the conveying path 18 .
  • the conveying path 18 is formed by rolls 21 , which are electrically insulated with respect to their environment or are made of a non-conductive material, in order to prevent undesirable current flows resulting from the electromagnetic fields generated by the inductors 14 to 17 a.
  • the inductors 14 to 17 a are supplied with electricity in a manner known per se by means of medium voltage generators, transformers and medium frequency converters (not shown), which are accommodated, in each case, in the housings of the heating devices 10 to 13 , which housings are oriented, with respect to the longitudinal orientation of said inductors, transversely to the conveying path 18 .
