Abstract：The deformation of hard inclusion in the cold rolling process of DC03 steel sheet has been focused on, and the effects of reduction, inclusion size and position in the strip were investigated. A two-dimensional elastic-plastic finite element model of five-stand tandem rolling was established with ANSYS/LS-DYNA analysis software. The process of continuous rolling was simulated by a small scale restart method. The results show that the simulated results are reliable. The deformation of inclusions increases with reducing of the thickness of strip, enlarging of inclusion’s diameter and decreasing of the distance between the inclusion and the surface of strip. Meanwhile, when the diameter of inclusions are larger than 20μm, it is mostly likely to form the crack due to the crashed of inclusion when the thickness of strip is rolled from 3.0mm to 0.7mm.
