六辊UCM轧机中间辊倒角优化

 本文采用影响函数法对UCM六辊轧机的辊系弹性变形进行了分析与计算，研究了不同的中间辊倒角对辊间接触压力的影响，为减少辊间接触压力峰值，优化出了适合不同带宽的中间辊倒角形状参数，从而减缓了轧辊的磨损，避免了轧辊剥落现象。

Optimization of Intermediate Roll Chamfer for UCM-Type Six-Roller Mill

For a better control of strip shape, bending force must be applied besides roll shift of intermediate roll of UCM-type six-roller mill, so that there will be stress concentration point in the contact area between intermediate roll and work roll, which makes the roll abrasion become quick, and even results in roll peeling off. The mathematic model of elastic deformation of UCM rolling mill has been developed by using influence function method. In order to reduce the peak value of contact pressure, a chamfer has been used in the end of intermediate roll. The parameter of intermediate roll chamfer have been optimized which can be applied to different kinds of strips. After optimizing, the peak value of contact pressure has been reduced, the roll abrasion has been relieved and the roll peeling also has been avoided.
