Abstract: Addressing the chronic problem that the PQF roll is often relatively dislocated with the roll shaft,and gets broken as well,a new idea is proposed,involving the roll-shaft monolithic structure design,and the centrifugal casting process for manufacturing composite rolls,while action of optimization of the roll-shaft separation structure is taken. Relevant operation practice shows that the application result of the optimized design of the Φ258 mm PQF rolls is as satisfactory as expected. Moreover,the service spans of the roll-shaft monolithic structured-roll and the roll-shaft separation structured-roll are compared,which further shows the significance and effectiveness of the design modification of the rolls.
