　　光整机是连续退火机组中使带钢发生形变的工艺设备。与常规轧制不同，光整机轧制是一种小形变量的轧制，其控制精度直接影响带钢产品质量和深加工性能。本文以首钢冷轧连续退火机组中光整机的张力波动造成带钢产品质量下降为背景，从光整机的控制模式出发，研究了光整机张力控制的原理，分析了光整机张力波动大的原因，对相关功能进行了排查和整定，并对张力控制参数进行了优化，从而解决了光整机张力波动大的问题，保障了生产的顺利进行。

Skin pass mill (SPM) is the process equipment to make strip reformatting in continuous annealing line (CAL). SPM rolling is different from the normal rolling. SPM rolling is a kind of small deformation of rolling. The control precision of SPM directly influences product quality and processing property of strip. In this paper, a decline in the quality of products is caused by the tension fluctuation of SPM in CAL of Shougang cold rolling mill. Taking this as the background,this paper explains the control mode of SPM, researches the principle of tension control system, analyses the reason of the tension fluctuation, inspects and adjusts the related functions, optimizes the tension control parameters, and solves the problem of tension fluctuation for SPM, so as to ensure the smooth production.
