Abstract
PURPOSE: To expand a control range by a method wherein a most suitable cutting length is obtained by inspecting an available range at that moment with respect to each cutting while an introduction of an estimated value with a smaller error obtained during a procedure of a rolling work is effected systematically.
CONSTITUTION: A cutting length is preset by the first time cutting length presetting device 13 and a rolled material 1 is cut by a shearing machine controller 14. Before a second cutting, the rolled material 1 passes through a stand 15. A pulse generator 16 counts a total number of pulses during the rolled material 1 is on the stand 15 and an estimating device 17 outputs a cutting length estimated value with an error smaller than that estimated in an estimating device 12 into the second time cutting length presetting device 18 in accordance with the counted value. The presetting device 18 determines the second time cutting length and the rolled material 1 is cut by the shearing machine controller 14. In a similar manner, the third time cutting length is determined by a presetting device 21 and the third cutting is effected.
