Definitions

  • the invention relates to an apparatus for the continuous casting of metals, in particular of steel, with a plurality of successive segments, each of which form the strand guide for different width casting strands by means of roller pairs of upper and lower rollers.
  • a cast slab profile is essentially an image of the roll gap geometry in the region of the Resterstarrung the cast strand. Different strand widths and casting speeds lead to different roll deflections and to different deflections of the trusses of the segment frame and thus to a variable profile cant.
  • the roll deflection and the traverse deflection are determined by the position of the sump tip, by the set thickness reduction and by the steel grade.
  • the roll deflection and the traverse deflection are determined by the position of the sump tip, by the set thickness reduction and by the steel grade.
  • slabs with slitting device single or multiple longitudinal division
  • the profile elevation slabs with alternating wedge shapes which in turn leads to problems at low Endwalzdicken there.
  • European patent application EP 1 043 095 A1 discloses an apparatus for continuously casting metals with a strand guide. This comprises a plurality of successive segments, each having roller pairs of upper and lower rollers for different width casting strands.
  • the strand guide comprises double-sided strand guide frames, which are connected to each other via segment cross members and a cross-beam.
  • the segment rollers are rotatably mounted on the segment cross members. At least on the fixed side of the segment frame is between the segment frame and the crossbeam an approximately lying on the strand center axis force member provided, the force transmission element engages the segment frame and the receptacle is supported on the crosspiece.
  • European Patent Application EP 0 941 787 A1 discloses a continuous casting plant in which the upper and lower rolls of the strand guide can be influenced by a hydraulic cylinder supported on a crossbeam. With the help of the hydraulic cylinder, the crowning of these rollers can be adjusted. However, there is assigned to a pair of guide rollers forming a roller gap, an adjustment for setting a crowning of the roller gap.
  • the present invention seeks to provide an alternative device for continuous casting of metals, which also allows the adjustment of the crowning, and reduce such variable profile increases in the field of Enderstarrung, so that the described consequences in subsequent rolling not may occur.
  • the segments are followed by a slitting device.
  • the setting of the profile cant just before the slitting device allows a dimensionally accurate influence, so that the required for rolling profile cant is just fixed at this point.
  • the force member may consist of a plunger which can be acted upon on one side.
  • the force member consists of a two-sided acted upon, hydraulic piston-cylinder unit.
  • the force of the force member can be regulated as a function of the segment loading by the cast strand. As a result, an overload of the segment frame can be avoided.
  • This regulation can also take place in such a way that the force of the force member can be transferred to the support roll and traverse deflection as a function of the segment load, contrary to an expected profile cant of the cast strand cross section.
  • the force of the force member may also be advantageous for the force of the force member to be adjustable on the loose side of the segment.
  • the same or similar advantages are achieved, which are described to the arrangement of the force member on the fixed side of the segment.
  • Another application of the basic idea according to the invention is that the force of the force member is adjustable at the same time on the fixed side and on the loose side of two opposing segment frames.
  • each segment frame may have a plurality of force elements associated therewith.
  • the course of the bending line can be set for a traverse.
  • a special embodiment further consists in the fact that the deformation characteristics of a segment are stored in tables in a computer and that the force of the force member from the stored values corresponding to the segment load can be retrieved. This makes it easy to use the values collected from experience and construction dimensions for the proper bendline.
  • the apparatus for continuous casting of metals in particular of steel, consists of a plurality of successive segments in the strand 1, in each of which by means of pairs of rollers 2, which may consist of divided rollers 3 and upper and lower rollers, represent the strand guide for the casting strand 4 ,
  • the casting strand 4 may have a different width 4a.
  • the cast strand 4 has, to indicate the location of the position of the segment 1, in the region of Resterstarrung 4b a strand shell 4c on ..
  • the pairs of rollers 2 are rotatably mounted on segment frame 5, 6, wherein a segment frame 5 act as a fixed side and a segment frame 6 as the lot side , Both segment frames 5 and 6 are adjustable by means of pull cylinders 7 against each other, whereby the thickness 8 of the cast strand 4 is met.
  • the consisting of the segment frame 5 and 6 and the pull cylinders 7 segment 1 is clamped by means not shown clamping cylinders 9 on a double-sided strand guide frame 10.
  • the force member 13 may consist of a plunger 14 which can be acted upon on one side or of a hydraulic piston-cylinder unit 15 which can be acted upon on both sides.
  • the force of the force member 13 is adjustable in dependence of the segment load by the casting strand 4.
  • the force of the force member 13 can also be made adjustable on the loose side 6 of the segment 1. In special cases, it may be advantageous that the force of the force member 13 at the same time on the Fixed side 5 and on the lot side 6 of two opposite segment frame 5; 6 is set.
  • Each segment frame 5, 6 can each be assigned a plurality of force members 13.
  • the deformation characteristic 19 of a segment 1 is stored in tables in a computer and the force of the force member 13 can be retrieved from the stored values corresponding to the segment load.
  • the truss cross-section 20 of a segment 1 can be selected to minimize the force of the force member 13 as a function of the segment load.
