摘　　要：宽度精度控制是热轧带钢产品质量的重要指标,偏差每减小1mm,成材率可以提高0.1（左右,采用本文介绍的短行程控制有效解决了头尾失宽,带钢缩颈补偿技术有效解决拉伸引起的失宽,动态补偿技术增强了宽度自适应控制效果,文章对于冶金带钢轧制宽度控制系统的设计应用有很大的参考价值。The precision of width control is an important index for hot rolled strip steel quality. The rate of finished products increases by about 0. 1 percent as the deviation minishes 1 mm. The SSC can solve the width lose control of head and tail. The necking compensation technology for strip steel can effectively solve the width lose control caused by stretching. The dynamic compensation technology boosts up the effect of width adaptive control. This paper is of great reference value to the design and application of the automatic width control system.

关 键 词：动态控制 前馈控制 短行程
