The Process Research and Numerical Simulation of Composite Roll

Abstract:

Due to obtain good mechanical properties and cost savings etc. composite roll is widely used in rolling steel industry. It is important significance for composite roll interference fit to study because assembly interference fit between roller sleeve and mandrel affect directly the performance of composite roll. In paper the calculation format of interference fit is obtained by deriving theoretically the interference fit process of composite rollers roller sleeve and mandrel. At the same time, the numerical calculation of the maximum amount of interference between roller sleeve and mandrel is done by finite element method, the results show that the theoretical calculation and finite element calculation are basically consistent, thus provide a theoretical and design for composite roll designer and has important practical value.
