In this paper, the mathematical formula to calculate the transient tension of the strip being rolled in hot tandem mill is derived by way of analyzing the causes to form the transient tension, and several effective tactics to control the transient tension are introduced in order to obtain the strip production being up to standard.
本文通过对产生带钢瞬变张力的原因的分析，导出计算带钢瞬变张力的数学表达式，然后介绍若干行之有效的控制瞬变张力的策略，以便在热带钢的连轧生产中得到合格的带钢产品。
he BS-3 model control system with varying tension is composed of a tachometer generator of the main motor,a tachometer generator of the brake,a radius sensor,a brake and a control cabinet.
采用主电机测速器、制动器测速器、半径传感器、制动器及控制柜组成的ＢＳ－３型变张力控制系统，比用张力反馈式控制系统结构更简单、操作更方便、控制效果更好。
