Abstract:

In order to deal with the problems that the collapse displacement of sleeve offseted the hydraulic crown of a VC mill, to weaken the shape-control effect of the mill and to cause the bilateral wave plate shape defects of finished strips when rolling by large rolling pressure, the equipment and process characteristics of VC mill were fully integrated to put forward an optimization design technique of the inner roll shape of VC mill. The partial contact that appears between the sleeve inner wall and the mandrel surface when rolling by large rolling pressure can control the collapse displacement of sleeve to the extent permitted and restrain the occurrence of bilateral wave plate shape defects by means of the design of the inner roll shape of VC mill. The range of flatness control is improved and the application of VC mill is expanded.

Key words:  VC mill, inner roll shape, collapse displacement, plate-shaped
