Abstract

PURPOSE: To control the interstand tension to an optimum value, by operating the control gain for the tension control, and by giving this control gain to the tension controller.
CONSTITUTION: At the continuous hot rolling mill including plural rolling stands respectively equipped with the tension controller for keeping the tension between each stand at the aim value, the optimum value of the tension control gain is operated depending on the deformation-resistance and the size of the rolled material. This tension control gain is automatically set in the tension controller, and the interstand tension is controlled by changing the tension control gain according to the rolling condition.
