Abstract

PURPOSE: To make possible the loop control to be carried out continuously, by giving the loop control signal at the moment of putting off the loop control to the mill driving motor as its reference speed, and by giving the loop control signal at the mement of putting on the loop control to the loop controller as the initial value.
CONSTITUTION: The value of the loop position setter 8 and the signal of the material position detector 3 are given to the loop control output circuit 11, and the motor 13 is driven through the speed controller 12, and then, loop position of the rolled material 14 is controlled. When the loop control is put off by the switching signal 15 of the loop conrol range setter 6, the loop control signal is memorized in the loop control signal memory circuit 10, and its value is inputted to the loop control output circuit 11; and when the loop control is put on, the memorized value is inputted to the loop control output circuit 11 as the initial value. According to this method, the smooth loop control depending on the limit control system beomes possible without giving damage to the material while the rolling is carried out.
