ABSTRACT:
A tension control system for use with a universal mill such as an H beam mill, in which a tension force in a billet, to be rolled, between roll stands is controlled so as to be maintained at zero. Providing that effective loads (Pu) are obtained by linearly summing horizontal and vertical rolling loads, the tension control system controls roll driving motors so as to maintain the respective ratios T/Pu of rolling torques T to effective loads (Pu) constant, thereby performing a non-tension control.
