The 3D FE model is built to simulate the 33Mn2V steel pipe piercing process in Mannesmann Mill. The Mannesmann Mill structural parameters provided by Wuxi Seamless Steel Tube Co.(WSSTC), Ltd. static implicit algorithm and Kumar constitutive equation are adopted in the model. By using MSC.Superform 2005, coupled ther- mal-mechanical simulation of two skewroll piercing process is carried out. The simulated result shows the defect such as crack and springback generated in the piercing process. Plastic strain value of gap nodes is identical to the calculated value. The reasons which caused the product defects are the elliptic hole cavity and improper sink value. Simulating results will provide a reference basis for the simulation design member and the product quality improve.
