Finite Element Analysis of Rolling Force and Torque during Hot Continuous Rolling of Hot Work Steel

The hot continuous rolling process for φ200 mm round bars of a hot work steel is simulated by using the three-dimensional thermal-mechanical coupled elastoplastic finite element method. The changes in rolling force and torque during the rolling process are calculated precisely. As a result, the roll strength and profiles can be verified and/or modified, from which a more reliable roll pass schedule can been chosen.
