Stress analysis and shrink range optimal design for the built-up composite sleeved roll in H-beam mill

Based on the stresses analysis and calculation for the built-up composite sleeved roll in the universal H-beam mill, by using the optimal design method of reliability, an optimal amount of shrink fit was obtained. The effects of material properties, residual stress and friction coefficient on the system reliability had been studied by computer simulation. The conclusion can be used to provide direction for choosing composite sleeve material and designing built-up method and roll structure.
