Abstract:A pass system to produce phi70-80 bearing steel rod by using 300mm billet was developed. With the aid of software MSC. Marc and its user subroutine,3D FE models for the rolling process coupled with the microstructure evolution model of GCr15 steel were established to simulate the deformation of rolled piece and the rolling force at every pass. Meanwhile, the evolutions of temperature, strain, strain rate and austenite grain size in the rolled piece were obtained. The work realized the virtual computer rolling before practical rolling of rod
