Abstract：To investigate the growth process of solidified shell in the mold at high casting speed for thin slab continuous casting. A two-dimensional solidification and heat transfer finite element model was developed based on ANSYS software. The rationality of model was verified by tested shell thickness. The process of shell formation is simulated for Q235B steel 1 500 mm×60 mm shin slab, and the effect of different casting speed and mold cooling water was studied. The results show that: the thickness of billet shell increases with the decrease of drawing speed, As the cooling water flow of the mold increases, the thickness of the blank shell increases, the trend of simulation and measurement was consistent, which provide the theoretical reference for optimizing process parameters.
