Numerical Simulation of Solidification Process in Slab Casting Mould Based on 3D MiLE Algorithm Model

According to the requirement of improving production efficiency and slab quality in a continuous steel slab caster,A 3D non-steady thermal-flow-stress model was developed to explore the solidification and flow process in mould.The width and thickness of slab are 1.2m and 0.2m,and respectively the steel grade is Q235B.The distributions of temperature,flow,stress and strain in caster were obtained by using the commercial software,ProCAST.The results show that the shrinkage of slab has different shape curve on different direction.Consider of the effect of gap width,the average temperature at mold exit increases form 1120.5℃to 1289.7℃,and the shell thickness decreases from 16.1mm to 14.2mm.
