Abstract：The finite element model was employed to simulate the solidification and shrinkage of continuous casting steels by means of ANSYS. Solidification processes for 20CrMnTi in the bloom continuous casting were simulated under different casting speeds and superheats, and the effects of casting speed and superheat on quality of bloom were discussed. The results show that when the superheat is increased at the same casting speed or the casting speed is increased at the same superheat, the degree of center segregation, center porosity, shrinkage cavity are higher. In order to effectively control the quality of casting billets, the superheat and the casting speed should be 10-25 ℃ and 0.75-0.85 m/min, respectively.
