A Method to Avoid Strip Breakage for Thin Strip Steel in Cold Rolling

Abstract:

An automatic control method to prevent thin strip steel from breaking in cold rolling is presented in this paper. The strip width detector is equipped at the entry and exit sections of the cold rolling mill respectively, thus the width reduction of the strip steel before and after the mill can be real-time detected . The signal of the width reduction rate exceeding a certain value means that the strip edge is too tight. Then, via the strip shape adjusting mechanism, the edge of the strip steel becomes loose and the strip breakage can be avoided. By applying this method, the incidence of strip breakage can be reduced and the productivity capacity can be increased, and more, the width control accuracy of the rolled steel strip can be improved. The validity of the proposed method is verified by the example simulation.
