Abstract：In order to solve the problem of hot rolled strip head narrowing caused by metal flow unbalance. Taking the hydraulic looper system of the hot continuous rolling mill as research objects, the control of the looper height was studied. And on that basis, the improvement strategies of the raising- up control of looper were put forward, such as the rapid compensation of the strip head flow, in order to realize the precise control of the tension of the strip head and looper height. With the 2 250 HSM hydraulic looper control system in Masteel as the research platform, the experiments on the functional improvement and parameter correction of the looper raising- up were carried out. Through the experiments, the problem of long- distance drawing of strip head was solved and the raise control performance of looper improved. And the raise control performance reference standard was established.
