Abstract

PCT No. PCT/DE93/00826 Sec. 371 Date Mar. 29, 1995 Sec. 102(e) Date Mar. 29, 1995 PCT Filed Sep. 8, 1993 PCT Pub. No. WO94/07618 PCT Pub. Date Apr. 14, 1994The rotational speed of the rolls of a rolling mill is controlled such that the loops of rolled material between two roll stands have a constant height. The last roll stand in the direction of rolling preferably acts as a guide roller stand, whose speed is controlled. The loop height is controlled by adjusting the rotational speed of the roll stand ahead of the loop.
