热连轧窄带钢的活套高度闭环控制

CLOSEDLOOP CONTROL FOR HEIGHT OF LOOPS IN CONTINUOUS HOT ROLLING OF NARROW STRIP STEEL

热轧窄带钢活套调节是影响窄带钢质量的重要问题之一。文中结合窄带钢连轧的特点介绍了活套高度闭环控制系统，并对系统涉及到的有关问题作了说明。

The adjustment of loops in hot rolling of narrow strip steel is an important factor which influences the quality of narrow strip steel. In combination with characteristics of continuous rolling of narrow strip steel, this paper introduced closedloop control system for height of loops, and des cribed come problems related to the system.
