辊型优化技术在宝钢冷轧平整机上的应用

将平整机轧制力和剪张应力横向分布的数学模型。与平整机辊系弹性变形相结合，建立了平整机板形计算理论，在此基础上以前张应力偏差平方和为目标函数优化设计了宝钢冷轧厂ＣＡＰＬ平整机工作辊辊型和支承辊肩部辊型，并优化了弯辊力设定值。产生实验表明，优化辊型提高了平整机的稳定性，因板形不良导致的废次品量、封闭量下降。用该优化结果制定的支承辊辊型磨削加工标准已用于工业生产。

The application of the roll crown optimization technique in skin pass mill in Baoshan Cold Rolling Plant

On the basis of the mathematics models of rolling force and transverse distribution front tension combined with the elastic deformation of rolls, the calculation theory for strip shape is established. The work roll and back up roll shoulder curves and bending force of CAPL skin pass mill are optimally designed depend on the aim function of the total square-error of front tension. The practical production shows the optimized roll crown curves improve the stability of mill, and decrease the waste product rate. The abrasion-forming standard for back up roll has been applied in production based on optimized result.
