Definitions

  • the invention relates to a method for producing a metallic strip by means of endless rolling, in which a slab is first cast in a casting machine and this is then rolled continuously in a rolling train with at least one roll stand (it can also be pre-rolled endlessly and the strip can be finished discontinuously), wherein the casting machine has a strand guide in which the cast slab is guided in the conveying direction in the direction of the rolling mill, the material of the slab in the region of the strand guide being cooled by spraying a cooling medium by means of a number of cooling devices, each cooling device having a number of spray nozzles which are arranged side by side in the direction transverse to the conveying direction and via which the cooling medium is applied to the slab.
  • the invention further relates to a device for producing the band.
  • a casting machine usually has to produce different material qualities.
  • soft carbon steel is cast at a high speed and a casting machine length is designed based on this.
  • high-strength materials e.g. micro-alloyed steels and high-carbon steels
  • silicon steels the casting speed is reduced for quality reasons. This leads to a solidification further inside the casting machine.
  • a generic method is in the WO 2008/145222 A1 described.
  • Other solutions reveal that WO 89/11363 A1 , the DE 690 07 240 T2 , the DE 10 2010 022 003 A1 , the EP 2 527 061 A1 , the DE 32 30 866 A1 , the DE 10 2009 019 784 A1 , the DE 100 51 959 A1 , the WO 2012/107143 A1 , the DE 10 2008 049 537 A1 and the WO 2008/025325 A1 ,
  • the invention is therefore based on the object of further developing a generic method in such a way that it is possible with little effort to improve the slab or strip quality, in particular in the edge region.
  • the compensation distance is preferably not longer than 120%, maximum 200%, of the above-mentioned minimum value.
  • the slab is preferably heated in its edge region along the compensation path between the casting machine and the rolling mill.
  • the average temperature in the edge area of the slab is preferably kept at least 20 K higher, preferably at least 100 K higher than the average temperature in the central area of the slab, at least at one location along the conveying direction of the slab.
  • the edge area of the slab is preferably kept free of sprayed-on cooling medium or with a reduced cooling effect over a range between 40 and 150 mm from the lateral slab end.
  • the spray zone width is preferably divided into narrow width sections which can preferably be acted upon separately by cooling medium, preferably between 50 mm and 300 mm, particularly preferably between 50 mm and 100 mm, in order to be able to optimally adapt the active water quantity to different slab widths.
  • a further development provides that a temperature increase between the temperature of the slab in the edge area and the temperature of the slab in the middle area from the start of solidification of the slab to the end of solidification of the slab is preferably carried out continuously.
  • the slab is preferably heated within a thermal insulation.
  • At least one segment of the casting machine can be replaced by a lateral shift by a thermally insulated roller table that can be moved transversely to the conveying direction.
  • the device for producing a metallic strip by endless rolling comprising a casting machine for casting a slab and a rolling mill adjoining it in the conveying direction of the slab with at least one rolling stand, the casting machine having a strand guide in the material of the slab in the conveying direction in the direction of the rolling mill is guided, with a number of cooling devices being provided with which the slab can be cooled in the region of the strand guide by spraying on a cooling medium, each cooling device having a number of spray nozzles which run in the transverse direction Are arranged next to each other to the direction of conveyance and via which the cooling medium can be applied to the material of the slab, is characterized according to the invention in that control means are provided in order to be able to operate at least one of the cooling devices in such a way that only a number in the central region of the slab Arranged spray nozzles cooling medium is applied to the slab, while no or only a limited amount of cooling medium is applied to the slab via the spray nozzles located in the edge region of the slab, with thermal insulation in the area
  • a heating device is preferably arranged, which is designed to heat the slab along the compensation section between the casting machine and the rolling mill in its edge region.
  • the zone widths or distances of the spray nozzles in the width direction of the slab are preferably between 50 and 300 mm, preferably between 50 and 100 mm. This makes it possible to positively influence the temperature distribution across the width.
  • the thermal insulation in the direction transverse to the conveying direction can be arranged displaceably.
  • a thermally insulated roller table with thermal insulation that can be moved transversely to the conveying direction can be arranged.
  • the proposed measures improve in particular the slab and thus the strip quality at the edge.
  • the invention is based on the knowledge that normal cooling in the rear area of the casting machine and during subsequent transport to the first roll stand, this has a particularly negative effect on the edge. In order to prevent this, it is provided that within the casting machine by deliberately switching off or reducing the segment cooling in the area close to the slab edges, these are kept warmer.
  • the slab edge region is preferably kept in the range between 40 to 150 mm from the edge up to being warmer than the middle of the slab by solidification by at least 20 K, preferably by at least 100 K.
  • the proposed measures regarding both the procedure and the design of the corresponding device result in addition to the temperature increase in the edge region of the slab or the strip, compressive stresses on the edge, which have a positive effect on edge cracking.
  • the slab on the top and bottom as well as on the slab edges can be provided Optimally less to cool, to insulate, to keep warm or to warm the edge until shortly before the first rolling stand.
  • Descaling of the slab for example in front of the first inline stand, is optionally dispensed with, preferably in the case of high-strength materials; this area can be thermally insulated.
  • the proposed solution advantageously results in an improvement in the slab or strip quality at the edge, in particular in the case of high-strength materials.
  • slab edge cracks during subsequent forming can be avoided.
  • a casting strand or slab 1 can first be seen, which in the conveying direction F (which in FIG Figure 1 stands vertically on the drawing plane) the strand guidance of a casting machine happens.
  • a cooling device in the form of a cooling beam 6 is arranged above the slab 1, the cooling device having a number of spray nozzles 7 arranged next to one another.
  • Cooling medium 5 water or a water-air mixture can be sprayed onto the strand surface in order to cool it.
  • the casting strand 1 extends in a direction Q transverse to the conveying direction F and has a central region M in and an edge region K.
  • the overheating of the edge region K of the cast strand or slab 1, ie. H. the temperature increase of the edge region K relative to the central region M is advantageously increased successively from the start of solidification to the end of slab solidification.
  • the segment cooling (for the entire casting machine or only in the area of the front or rear half of the casting machine in the conveying direction or alternately over the length of the casting machine) can be very finely structured across the width in order to be able to optimally set the desired effect for the different widths.
  • Zone widths between 50 and 300 mm and particularly preferably between 50 and 100 mm above the width in the range of 90% from the minimum slab width to the maximum slab width are provided in order to avoid cold slab edges.
  • the zones on the top and bottom and from roll to roll can be arranged offset by a half (or integer divided) nozzle pitch.
  • Quantity-controllable two-substance nozzles are advantageously used as spray nozzles.
  • the water quantities of the individual spray nozzles, which should remain passive, in the slab edge area and next to the slab can be reduced to zero, so that only a little nozzle cooling water or only air (to protect the nozzles) flows out. This effect can be supported by the use of dry segments in the rear area of the casting machine.
  • the deactivated ones can alternatively be used Nozzle bar can also be moved out of the casting line or swung out.
  • the absolute slab edge is somewhat colder than the slab in the middle or the mean temperature over the thickness in the area, because water partially flows over the edge and there is a two-dimensional radiation of heat. Due to the overheated slab edge area provided according to the invention and the subsequent additionally provided optional thermal insulation, however, there is advantageously a further temperature rise of the absolute slab edge there due to the temperature compensation or the heat conduction from the center to the edge or the lateral outer surface.
  • Curve a shows the temperature distribution up to the slab edge after solidification, which is generated by reduced segment cooling or by switching off nozzles in the edge area.
  • Curve b shows the temperature distribution after solidification in the casting machine without overheating of the slab edge according to the invention. It can be seen that the slab edge has become significantly colder.
  • Curve c shows the temperature distribution up to the slab edge at the inlet of the inline stand with the slab edge overheated according to the invention or reduced segment cooling in the casting machine (without insulation).
  • Curve d shows the temperature distribution up to the slab edge at the inlet of the inline stand without overheating the slab edge in the casting machine (without insulation).

  • the arrow f indicates the potential that can be achieved according to the invention for increasing the slab edge temperature at the inlet of the inline stand.
