Mastering of the Technology of Assembling of Composite Mill Rolls Under the Conditions of Rail and Structural Steel Shop at the JSC “EVRAZ ZSMK”

Resumo

We develop a technology of assembling of composite mill rolls for the universal stands of the rail and structural steel shop at the JSC “EVRAZ ZSMK.” The proposed technology is based on the method of thermal shrink-fitting, including the application of bandage made of cast iron. The investigations are carried out to determine the optimal temperature and time parameters of the process of assembly.
