Description

<p>The bimetallic work rolls are widely used in the roughing stands of hot rolling stand mills. The rolls are classified into two types, one is a single-solid type, and the other is a shrink-fitted construction type consisting of a sleeve and a shaft. Regarding the shrink-fitted type, the interfacial slip occurs and causes damage between the shaft and the shrink-fitted sleeve. In this paper, by varying the shaft material, the FEM simulation is performed to realize the interfacial slip. The effect of the shaft deformation on the interfacial slip is clarified as well as the effects of the shrink fitting ratio, and motor torque in relation to the slippage zone along the interface.</p>
