Definitions

  • the invention relates to a casting and rolling plant and a method for producing metallic rolling of carbon steel.
  • Such casting machines and methods are basically known in the prior art; see, for.
  • European Patent Specification EP 1 833 623 B1 discloses a cast roll mill for producing slabs with a mold, a mold guide downstream of the mold for deflecting the cast strand from the vertical to the horizontal, a heating furnace, a descaling device, a roughing stand, a Steckel mill Scissors, a cooler and a reel. After passing through the heating furnace, the cast strand or slabs first pass through the roughing stand before they enter the Steckel mill. All components of the system are in one line.
  • European Patent EP 1 940 566 B1 discloses a thin slab caster with a tandem rolling device. Already in the strand guide a reduction in thickness of the cast strand is provided; a so-called Liquid Core Reduction LCR area. The radius for the deflection of the casting strand in the horizontal is less than 2 m, the casting thickness is 25 - 32 mm and the casting speed is 6 to 16 m / sec.
  • German publication DE 196 81 466 T1 discloses a casting and rolling plant for producing metallic rolling stock, comprising a casting line with a mold for vertical casting of a cast strand and with a strand guide, which has a carpet for deflecting the casting strand from the vertical to the horizontal, a straightening device, a pair of scissors for distributing the casting strand in slabs and an outlet roller conveyor.
  • the casting rolling mill comprises a rolling line with an inlet roller table and a Steckel rolling mill for rolling the slabs of rolling stock, a Steckel rolling mill downstream cooling device and a cooling device downstream winding device.
  • a transverse displacement device is arranged for transversely transporting the slabs from the outlet roller conveyor of the strand guide to the inlet roller conveyor of the rolling line.
  • An oven is provided for heating the slabs during transverse transport.
  • the invention has the object of developing a casting and a method for producing metallic rolling material according to the type described in the last paragraph to the effect that the heat losses during transporting the slabs from the casting line are further reduced in the rolling line.
  • This object is achieved by the claimed in claim 1 casting rolling.
  • This casting and rolling plant is characterized in that the furnace includes the complete transverse displacement device and at least part of the outlet roller table of the strand guide and at least part of the inlet roller table of the rolling line and that the inlet of the furnace for the slabs in the casting line and the outlet of the furnace for the slabs is arranged in the rolling line.
  • the claimed embodiment of the furnace has the advantage that the slabs are not only secured during their transverse transport, but already on the outlet roller conveyor of the strand guide and on the inlet roller table of Steckel rolling against unwanted cooling, because the furnace extends over these areas.
  • the widths of the openings or the doors in these openings can be substantially limited to the width of the Brannnnen. This is particularly advantageous in view of the energy losses or the energy balance of the furnace compared to the design of furnace doors in the prior art, where the furnace doors extend over the entire length of a slab, because the slab is retracted transversely into the furnace.
  • both claimed measures serve to reduce the temperature losses of the slab and to increase the efficiency of the furnace.
  • the claimed cast-rolling mill is used to produce rolling stock in the form of flat steel with an annual production of less than 700,000 t per year of carbon steel.
  • the system is characterized by a compact system layout and z. B. due to the lack of a Vorgerüstes and the high efficiency of the furnace by low investment and production costs. It is therefore particularly suitable for (new) steel producers in regions without their own flat steel production. It is used for casting slabs with widths between 700 and 1, 700 mm.
  • the heating gas is conducted in the oven in a flow direction which runs counter to the direction of movement of the slabs in the oven.
  • This countercurrent principle also leads to a significant increase in efficiency of the furnace, because the slabs are kept better warm in this way.
  • the furnace has a further opening, which either serves as an outlet for slabs, which are not to be introduced into the rolling line or acts as an inlet for slabs, which should not be supplied via the casting line of the rolling line.
  • the run-out roller conveyor of the strand guide is extended beyond the transverse displacement region of the furnace through the said further opening to the outside of the furnace in the casting line.
  • the roller carpet of the strand guide is formed from a plurality of segments, which are arranged one behind the other in the casting direction.
  • three to seven pairs of rollers are initially arranged vertically one above the other to form a vertical guide region for the cast strand.
  • five to eleven further pairs of rollers within the first segment which are arranged in an arc shape to form a bending region for bending the casting strand out of the vertical into a casting radius between 3.5 and 6.5 m, are arranged downstream of this vertical guide region.
  • the bending area which is still attributed to the first segment, followed by two to four other arc segments for further guidance of the casting strand.
  • the said compact design of the system is particularly evident in its supported length of ⁇ 12 m and in a low overall height of the casting rolling mill between 5 and 8 m.
  • the above object is further achieved by a method for producing metallic rolling stock according to claim 15.
  • This method is characterized in that the slabs enter the front side in the casting direction in the oven and backward end face in the rolling direction from the oven.
  • the advantages of this solution correspond to the advantages mentioned above with reference to the claimed cast rolling mill.
  • the casting rolling mill is planned for casting speeds between 1 and 3.5 m / min. After leaving the furnace, the slabs run directly into the rolling stand of the Steckel mill, are thinness reduced there in a first pass and are subsequently wound downstream of the rolling stand on a Steckel located there, ie a winding furnace located there Steckelwalzwerks. To increase the production efficiency of the slab is not first wound in a winding furnace located upstream of the rolling mill of the Steckel mill and cached before it enters the rolling mill of the Steckel mill.

  • the distributor is typically covered with cover powder and the mold with casting powder.
  • the mold 1 10 may be formed either of four parts, two broad sides and two narrow sides or as a frame mold. It preferably has an integrated level measurement, which for example works radiometrically or with eddy current.
  • the mold in particular if it has two narrow sides, preferably has a narrow side adjustment for format adjustment during the casting operation.
  • the mold is positioned vertically below the casting platform. It can be formed with or without funnel on the upper Kokillenkopf.
  • the crown When forming a funnel mold, the crown is 10 to 60 mm at the top mold head.
  • the exit of the mold preferably runs parallel, but in the case of a funnel mold it can also have a residual embedment ⁇ 10 mm.

  • the supported length of the casting machine is less than 12 m.
  • no appreciable thickness reduction of the casting strand is provided by means of Liquid Core Reduction LCR.

Les installations de laminage de coulée continue (100) connues de ce type comprennent une ligne de coulée et une ligne de laminage disposée décalée parallèlement à la ligne de coulée. Un transport de brames de la ligne de coulée transversalement à la direction de coulée vers la ligne de laminage a lieu à l'aide d'un dispositif de déplacement transversal. Pour réduire au minimum les pertes de chaleur du four et pour optimiser le transfert de chaleur du gaz chaud dans le four aux brames, selon l'invention le four (150) enferme dans la ligne de laminage le dispositif complet de déplacement transversal (130) ainsi qu'au moins une partie du train à rouleaux d'évacuation (128) du guidage de barre (120) de coulée continue et au moins une partie du train à rouleaux d'entrée (140) pour les brames. L'entrée du four pour les brames dans la ligne de coulée et la sortie du four pour les brames dans la ligne de laminage sont disposées de manière que les brames puissent entrer du côté frontal et sortir du four à l'arrière du côté frontal.
