Abstract

PURPOSE: To control chamber by moving a rolled stock in the width direction with edger rolls of a hot rolling mill.
CONSTITUTION: In a rolling line which is arranged with a 1st rolling equipment which is provided with a 1st stand in which a rolling load measuring means and roll gap adjusting means are provided, means for measuring the temp. and thickness of rolled stock which are provided on the inlet side of the 1st stand and means for detecting the position in the width direction of the rolled stock arranged on the inlet and outlet sides of a (n-1)th stand, and an n-th rolling equipment which is provided with a position detecting means which is provided on the inlet and outlet sides of an n-th stand provided with a rolling lead measuring means and roll gap adjusting means; feed forward control that is implemented with the edger rolls so as to correct the camber of the rolled stock by calculating wedge ratio, camber ratio and temp. difference in the width direction of the rolled stock from the measured value of the 1st rolling equipment and feedback control that the position of the edger rolls is adjusted so as to correct chamber by calculating camber by the position ion the width direction of the rolled stock on the inlet and outlet sides of the n-th rolling mill are involved.
