Definitions

  • the invention relates to a method and a plant for the casting-rolling of metals, in particular steel, at high speeds, at which the continuously produced casting strand completely solidifies and, after passing through a temperature compensation section, is fed to a roughing mill and subsequently interposed and in several rolling mills is finish-rolled before being subjected to further treatment processes in the form of a rod or wire.
  • Casting and rolling systems for steel for casting relatively large casting cross sections have also become known, which have a roughing mill arranged directly behind the secondary cooling section of the casting machine. This arrangement was intended to shorten the solidification length and to distribute and close non-metallic inclusions and cavities in the cast strand more evenly.
  • the excessive deformation of the liquid strand core during the pre-rolling caused such high stresses that cracks formed in the strand core which prevented further deformation.
  • the invention has for its object to provide a method and a system for casting rolling, in particular steel, which allow a high output with relatively low investment costs.
  • the method and the system should also be designed so that the particularly high Casting speeds required space is reduced.
  • the idea of the solution on which the invention is based then consists in equipping the casting and rolling plant with two mutually independent complete casting sections, to which a single roughing mill movable transversely to the casting direction is optionally assigned.
  • the second casting line is put into operation in the event of failure of the other casting line, so that the downstream rolling mill can continue to work with a short interruption.
  • the displaceable arrangement of the roughing mill has the advantage that the casting strand can be introduced into the mill stands of the roughing mill without being deflected.
  • each casting section can additionally be equipped with a drive unit; this is located behind the temperature compensation section, advantageously in the area between the latter and the subsequent shear.
  • the plant according to the invention is further designed in such a way that a 180 o- deflection unit is arranged in the region between the roughing mill and the rolling treatment final finishing train, which determines the direction of movement of the cast strand during the further treatment processes.
  • the 180 ° deflection unit is in any case arranged in an area behind the roughing mill, that is to say in an area in which the cross section of the pre-rolled casting strand has no particular difficulties with. the deformation associated with the deflection.
  • the length of the casting and rolling system may be reduced by up to 50%; This not only leads to a reduction in the length of the hall, but also to a reduction in the installation costs for the oil, water, air, hydraulic and electrical supply to the casting and rolling system.
  • the 180 ° deflection unit is at most behind the second intermediate street (claim 3); Depending on the operating conditions, it can also be expedient to arrange the 180 ° deflection unit between the two intermediate streets.
  • the rolling stands of the roughing mill can be moved with respect to their fixed rolling drive (claim 5).
  • the rolling stands of the roughing mill are each arranged on their own sliding frame and connected to their rolling drive via cardan shafts (claim 6).
  • the casting and rolling plant is to be used for wire production, it preferably also has the features of claim 7 and / or claim 8.
  • the process for casting metal rolling is essentially characterized in that it has the characteristics of Claims 9 and / or 10.
  • the method can furthermore be designed such that the casting strand - which is optionally produced from different casting sections - reaches its effective area by moving the roll stands of the roughing train transversely to the casting direction.
  • the casting lines 1 and 1a which are preferably constructed in this way, are followed by a single roughing line 7 common to both casting lines, which in the exemplary embodiment shown is composed of three roll stands 8, 9 and 10.
  • the roughing mill 7 can be moved transversely to the casting direction (arrow 11) such that it lies either in the region of the longitudinal axis 12 of the casting section 1 or in the region of the longitudinal axis 12a of the casting section 1a.
  • the two above-mentioned operating positions, in which the preliminary road 7 is assigned to the casting line 1 or the casting line 1a are denoted in the drawing with solid lines or with dash-dotted lines; the transverse displaceability of the Vorée 7 is to be indicated by a double arrow 13.
  • the use of two mutually independent casting sections 1 and 1a is intended to ensure that the production of the casting and rolling system can be maintained in the event of a casting section failure, in particular a casting machine.
  • the casting machines 2 and 2a are designed in a manner known per se; they can in particular consist of two casting belts delimiting a casting cross section or of a casting wheel which interacts with a suitably designed casting belt.
  • the liquid steel to be processed is cast into a casting strand in one of the two casting machines - for example in the casting machine 2 - and there it receives an approximately 10 to 20 mm thick shell.
  • the casting strand solidifies under the influence of an intensive one Water cooling completely through, in the temperature compensation section 4, the temperature gradient between the strand shell and the strand core is reduced and, if necessary, the casting strand back to rolling temperature. temperature is heated.
  • the two casting lines 1 and 1a are connected by the rolling mill, which consists of the aforementioned roughing mill 7, a first intermediate mill 14, a 180 ° deflection unit 15, a second intermediate mill 16, a finishing mill 17, a primary cooling section 18, a winding layer 19, one Secondary cooling section 20 and a collecting station 21.
  • the casting strand pre-rolled in the roughing mill 7 and reduced to a suitable cross-section is further deformed in the intermediate streets 14 and 16 before it receives the desired wire cross-section when passing through the finishing train 17.
  • the deflection unit 180 0- 15 In the area between the roughing train and the finishing train 17 7 - in the illustrated embodiment, between the two intermediate trains 14 and 16 - passes through the cast strand, the deflection unit 180 0- 15; he thereby receives a movement direction 22 opposite to the casting direction 11, which remains during the subsequent treatment processes.
  • the casting strand runs, for example in wire form, through the primary cooling section 18 of the rolling mill, is turned into turns by means of the winding layer 19 and is guided over the secondary cooling section 20 of the rolling mill before it is collected into wire rings in the collecting station 21.
  • the deflection of the casting strand - which, depending on the cross section, can be carried out before, between and after the two intermediate streets 14 and 16 - leads to one Significant reduction in space requirements and installation costs for the supply equipment of the casting and rolling plant.
  • the displaceable arrangement of the roughing road 7 makes deflection of the casting strand, which still has the full casting cross section in this area, superfluous.
  • the roll stand 8 of the roughing mill lying in front in the casting direction is an example. 7, which can be moved back and forth in the direction of the double arrow 13.
  • the schematically represented rollers 8 ′ and 8 ′′ are connected to a gear 24 by means of cardan shafts 23 and, with the interposition of a clutch 25, to a motor 26 serving as a roller drive arranged.
  • the roll stand 8 (like the other roll stands 9 and 10 of the roughing mill 7, not shown) is movably held on a sliding frame 28 within a fixed guide 29.
  • the displacement frame 28 is connected in an articulated manner to the piston rod 30 'of a cylinder unit 30, which serves as a displacement drive and in turn is held in a stationary manner via a bracket 31.
  • the sliding frame 28 of the roll stand 8 is equipped with a clamping device 32 which clamps it in the selected operating position with the guide 29 and thus holds it in place.
  • the roll stand 8 (and the subsequent roll stands of the roughing mill) assume a position in which the roll center 33 coincides with the longitudinal axis 12 indicated in FIG. 1 falls; the second operating position of the roll stand 8 is indicated by dash-dotted lines in FIG. 1.
  • the stationary arrangement of the roller drive and the displacement drive with respect to the roll stands has the advantage that the installation of these drives is simplified and the size of the masses to be moved is kept as small as possible.
  • the casting and rolling system and possibly the 180 0 deflection unit can - in contrast to the application example shown in FIG. 1 (downstream rolling mill line) also interact with a rolling mill for the production of fine steel.
