Method and device for selectively modifying the geometry of a band grinding in a roughing stand.

摘要

Method for hot rolling of the rolling stock in a rolling hot strip or rolling mills Steckel, wherein for adjusting the course of the rolling rolling mill rolls at least rotated, a box laminating, and pressure side compression against the material to be rolled, characterized exerted because for selectively modifying the geometry of the strip roughing rolling slab (4) in order to form bands roughing (5) control pivot RAC (20) for dynamic adjustment in the roughing stand, and - - control position (35) and force control (45) of the guides, at least one roughing stand (1) are used side (8, 9) fast and powerful arranged before and after the roughing stand (1), to whose control the piston position and the piston pressure of the cylinder-piston (12) which adjust the guides are used side (8, 9), and combined together so performed such that one or a plurality of passes, from a slab (4) with curved or wedge-shaped band roughing flat and free it as wedge (5) selectively by drive reversal or during the last conventional manner.
