Embodiment Construction

[0026] The continuous casting machine 1 is a vertical continuous casting device, from which the continuous casting slab 2 is drawn vertically from a (not shown) continuous casting slab mold and placed in a continuous casting support 3 Complete cooling between a row of continuous casting back-up roll pairs 3a, wherein the continuous casting strand 2 hardens. Here, the drive force is transmitted to the strand via at least two pull-off roller pairs 3b. A bending roller 4 is located below the pull-roll pair 3b, which bends the cast billet 2 out of the vertical position and simultaneously decouples the billet 2 from the dummy bar 15 . The backing roll 5 is here a fixed roll and a support during decoupling as well as a subsequent support and rolling point of the cast steel billet 2 in bending. During the continuous casting process, a free space 10 is formed in the foundation. Located at the end of the free space in the strand moving device is a straightening drive 6 which receives...

Abstract

A method and an associated continuous casting machine (1) for the continuous rolling of a metal, in particular a steel, slab produced at a casting speed with a thin steel slab in cross section, which slab is cooled The state is bent, straightened, cross-cut if necessary and fed into the first rolling stand for rolling after temperature homogenization. By changing the continuous caster, this method can also be used with the continuous caster, in support of vertical casting. The cast slab (2) is bent in one or more sections with a guide length adapted to the casting speed and conveyed in a loop supported from below before transverse cutting. into a straightening drive (6) which may be set deviating from the loop length.

Description

technical field [0001] The invention relates to a method for the continuous rolling of a thin steel slab in cross-section, produced at casting speed, of a metal slab, in particular a steel slab, which is rolled in the cooled state Bending, straightening, cross-cutting if required and feeding into the first rolling stand for rolling according to the homogeneous temperature, the invention also relates to a corresponding continuous casting machine. Background technique [0002] This method is used for so-called thin billets, which are cast to a thickness of 50-90 mm and rolled into strip. Compared with common continuous casting equipment and rolling lines, energy and processing costs can be significantly saved. It's best to use two different methods for this, but they give the same result. One way is to cast a thin 90mm slab and reduce it to 15mm in multiple rolling stages. The cooling produced during thinning is recompensated by a correspondingly long induction heating stat...
