Finite Element Numerical Simulation on Thermo-Mechanical Couple in Bloom Mold
A thermo-mechanical FEM model was developed to compute heat transfer and stress distribution of strand in continuous bloom casting mold based on air gap between solidification shell and mold copper, and considering the influence of mold flux on contact resistance and flux film resistance. The model calculation results show a very good agreement with the measured one, and shell thickness deviation is less than 2mm. Hence, the temperature and stress distribution at different casting speeds were obtained by using the model. It is shown that when the casting speed is increased from 0.7m/min to 0.9m/min, the strand temperature becomes higher and the solidification shell thickness becomes thinner, which will increase the cracking tendency near the strand shell corner.
