The hot continuous rolling process of 効00 mm Hll steel round bar for mandrel has been simulated and studied by using MSC. MARC 3- dimensional thermo-mechanical coupled elasto-plastic finite element method (FEM) and contact analysis technique. It is obtained by analysis that with decreasing last pass roller speed Vr the compression extent between passes increased; with increasing last pass roller speed V

the tensile extent between passes increased; therefore it is available to modify the relation between compression and tensile

value in order to increase the product dimension precision. It is concluded that the light compression technology between passes shall be adopted during heavy round steel continuous rolling to keep the stability of rolling load and torque and guarantee the require
