摘　　要：无论是冷轧机还是箔材轧机,其卷取机控制系统均为张力控制系统,一般工作在卷取或开卷两种状态。对控制的主要要求是维持带材的卷取张力为给定值(恒定或按比例变化)。为合理地利用电动机的功率,控制系统大都采用最大力矩调节方案。以下基于卷取状态推导电动机过载倍数的计算公式。All the recoiler control systems of both the cold rolling mill and the foil rolling mill are tension control systems and are generally operated in payoff mode or recoiling mode.The main control requirement is to maintain the tension to a given value (constant or propor- tional variation).In order to reasonably utilize motor power,a maximum torque djusting scheme is used for most of the control systems. The paper presents the deduction process of the formulae for calculating the overloading multiple of the driving motor in recoiling mode.
