Abstract：Based on the practical production condition of continuous casting bloom of 360mm×450mm made in a domestic steel plant， a 3D thermo-mechanical coupling model was applied to simulate the nature shrinkage of continuous casting bloom by using the finite element software MSC.MARC. Using thermal elastoplastic model， the temperature distribution and solidification shrinkage behavior of bloom under different casting speed was investigated. The results show that the more the casting speed changes， the smaller the temperature and the total thermal shrinkage； On the contrary， the smaller the casting speed changes， the more the temperature and the total thermal shrinkage； the free thermal contraction along the strands has different behaviors in width direction and thickness direction.
