Abstract

PURPOSE:To operate the following process efficiently by measuring the length of the last material by a detector disposed between a finish mill and a cutter and by changing the speed of a damper corresponding to the length so as to stop the last material at a certain set position and cut the material. CONSTITUTION:A cutter 3 and a detector 4 disposed at a distance l before the cutter are adapted to measure the length L of the last material 1 such as L= l-vt1 in case that there is a cutting signal of the cutter after the detector is turned off, and L=l+vt2 in case that there is no cutting signal after the detector is turned off, to judge whether the length L is (a) more than the trail edge of a steel material can be stopped at a set position even if a damper is operated at a normal speed, (b) between 1/2XL1 and under L1, or (c) under 1/2XL1. The damper is operated at normal one-cycle speed in case of (a), at a speed one cycle ligher in case of (b), and at higher speed than v3 in case of (c). When the damper is operated at a speed v1 at a point B, the last material can be stopped near a set position.
