Definitions

  • the invention relates to a method for producing flat products made of steel from continuously cast slabs of large or medium thickness or thin strands, which are compressed and then undergo a roughing and a finishing train.
  • a roller conveyor for transporting the flat products and for reversing.
  • the process is carried out by means of a hinged section provided with hinged, heat-insulating and cover hoods, an induction heating device for the controlled heating of pre-belts to a defined temperature over the pre-strip length and width, in a multi-stand finishing train, with a discharge roller table with means for cooling the conveyor Flat product and in downstream winding machines for winding the finished strip.
  • the transformation start temperature of the transition into the two-phase region is raised and, in order to lower the forming resistances, the conversion time is shortened.
  • the Vorband is uniform over its length and width by the combined effect of the closed covers and an inductive heating device to a targeted Temperature adjusted so that rolling takes place in the finishing mill for all stitches in the two-phase area.
  • the tinder scrubber is mounted in the rolling direction behind the roughing train and immediately before the finishing train and serves for descaling the surfaces, not the edges of the slabs.
  • a hot rolling method in which a compression device is provided for the lateral upsetting of the rolled strip in front of the roughing stand.
  • a descaling device is provided between the upsetting device and the roughing stand, by which the continuous casting slabs are descaled on their surfaces by water jets. Therefore, shielding plates are attached to the upsetting device on both side upsetting rollers to prevent the water of the descaling device from cooling the rolled strip at the sides.
  • the shield plates are attached to lateral guides, so that changes with a change in the bandwidth and the distance of the shielding plates to the rolled strip.
  • this object is achieved in the aforementioned method in that the flat products are descaled before upsetting at their band edges. Without the descaling of the strip edges, there is the danger that the scale will be rolled during upsetting and thus the quality of the rolled strip will be impaired.
  • the invention remedies this drawback of the prior art rolled strip.
  • the flat products are descaled once again at their strip edges after passing through the roughing train and before passing through the finishing train. Then they can be upset again.
  • the flat products are descaled at their strip edges by a fluid under high pressure, in particular at least one high-pressure water jet.
  • At least one high-pressure water jet is directed onto the flat products at an angle of 60 ° to 90 ° relative to the lateral surface of the flat products, in particular at an angle of 75 °.
  • the Entzu mattersstation before the roughing are preferably directed from three superimposed nozzles water jets on the band edges.
  • the invention also relates to a rolling mill for producing flat steel products from continuously cast slabs of large or medium thickness or from thin strands having a first upsetting device, a roughing train and a finishing train.
  • the rolling train is characterized in that a first descaling device for descaling the strip edges of the flat products is arranged in front of the first crushing device. Furthermore, in a development, a second upsetting device can be provided in front of the finishing train, and in front of this a second descaling device for descaling the strip edges of the flat products.
  • the first descaling device comprises at each of the two strip edges of the flat products a plurality of nozzles directed onto the strip edges, in particular three nozzles each.
  • the second descaling device corresponding to the lower thickness of the strip due to rolling, has at least one nozzle directed at each of the two strip edges of the flat products from which a fluid, in particular water, can be irradiated under high pressure onto the strip edges.
  • the nozzles on the side guides of the rolling train are attached to the ends of the side guides facing the compression device and are width-adjustable together with the side guides, in particular with the rulers.
  • the attachment of the nozzles to the side guides or rulers has the specific advantage that the distance between the nozzles to the band edge is always constant / equal, provided that the side guides or rulers are always moved out to the band edges (which always the case in practice is).
  • the constant distance of the nozzle to the band edge advantageously causes a constant impact of force (impact) of the water jet from the nozzles on the strip edges and thus a uniform Entzutitisrial.
  • the nozzles radiate the fluid respectively at an angle of 60 ° to 90 °, based on the lateral surface of the flat products, in particular at an angle of 75 °, on the band edges of the flat products.
  • Fig. 1 is a sectional view of the pre-strip and its leadership in one
  • Rolling mill for the production of steel flat products with a top view of a descaling device for removing scales from the side edges of the flat products and
  • Fig. 2 is a side view of the rolling mill of FIG. 1 in the area in front of a compression frame, partially cut.
  • a rolling train for example, downstream of a casting machine for producing large or medium-sized continuous slabs, comprises a pair of scissors for dividing the cast strand into slabs, a heating or equalizing furnace for heating the cold or warm continuously cast slabs or for balancing the thin strands to rolling start temperature and before a compression device 1 (FIG. 2) for laterally compressing the flat products, a descaling device 2 (FIGS. 1, 2) for descaling the lateral strip edges of the flat products, wherein the compression device 1 in turn is arranged in front of the roughing train.
  • the flat products or ribbons are conveyed via rollers 3.
  • At their two longitudinal edges of the flat products are guided by rulers 4, 5, depending on the width of the flat products at different positions. This requires that the two rulers 4, 5, symmetrically to the center in the direction of a double arrow A transversely to the rolling direction of the flat products are arranged slidably.
  • High pressure water jets arranged on the strip edges of the rolled strip. From each of the nozzles 6a, 6b, 6c, 7a, 7b and 7c, the water becomes conical blasted, covering the water jets to fully impact the side edges of the flat products and remove the scale
  • a protective wall 8, 9 which is preferably fixed in place by the spray walls 8, 9 in each case a flexible Medie ⁇ ket- te 10 or 11 runs, each having a high-pressure hose 12, 13 for supplying the water from a common supply line 14 with the change in the position of the nozzles 6a, 6b, 6c, 7a, 7b and 7c according to the width of the rolled strip can also be the media chains 10, 11 and with these the tubes 12, 13 relocate.
  • the nozzles 6a, 6b, 6c and 7a, 7b and 7c are respectively integrated on both sides with spray bars 15, 16 which form the mechanically rigid end piece of the tubes 12, 13.
  • the spray bars 15, 16 are mounted on the rulers 4, 5 and movable therewith. This ensures a constant effect of the water jets independent of the width of the rolled strip on the side edges of the rolled strip to remove the scale from them, so that this is not is rolled in the compression device 1, whereby the quality of the rolled strip is improved.

Abstract

L'invention concerne un procédé de fabrication de produits plats en acier à partir de brames coulées en continu de grande ou moyenne épaisseur ou à partir de barres minces qui sont refoulées et traversent ensuite un train ébaucheur et un train finisseur. Ce procédé se caractérise en ce que les produits plats sont décalaminés sur leurs bords avant le refoulement. Le procédé est mis en oeuvre dans un train de laminage comprenant au moins un premier dispositif de refoulement (1), un train ébaucheur et un train finisseur. Ce train de laminage est caractérisé en ce qu'un premier dispositif de décalaminage (2) servant à décalaminer les bords des produits plats est placé en amont du premier dispositif de refoulement (1).
