对连轧机精轧支承辊大面积剥落的原因进行了深入的分析，结果表明，轧辊内部的缩孔、气泡及热处理不当是造成轧辊表面剥落的主要原因。
It has been analysed the causes for the heavy surface spalling of back-up roll for a finishing mill. The result shows that the main causes are gas hole, shrinkage and bad heat treatment.
这些模型可以用于生产中预测轧后带钢表面粗糙度、合理安排带钢轧制顺序、决定工作辊下机时间和修正轧制力计算模型。
The models can be used to predict strip surface roughness, arrange steel strip rolling order reasonably, decide the time of work roll off mill and modify the calculation model of rolling force.
