1绪言冷轧轧制是要提高轧制板材的板厚精度及板形质量。特别是在轧机加减速时,随着轧制速度的变化、轧制材料及轧辊间的摩擦系数等会发生变化,轧制力及板厚也会发生变动。为防止末架出口侧板厚变动,特引入板厚控制系统。本板厚控制系统考虑到各种状况,需要对照不同轧机制定各种适 1 Introduction Cold rolling is to improve the thickness of the rolling plate thickness and shape quality. In particular, during the rolling mill acceleration and deceleration, as the rolling speed changes, the friction coefficient and the like between the rolling material and the rolls change, and the rolling force and plate thickness also vary. In order to prevent the end frame exit side thickness changes, special introduction of board thickness control system. The thickness control system taking into account a variety of conditions, the need to control a variety of different rolling mill fitness
