Abstract: A heat transfer mathematical model of generous slab continuous casting is established based on a steel continuous caster production practice． The numerical simulation of the solidification process for the Q 345C thick slab was carried out by using the commercial software ANSYS and changing the drawing speed，degree of superheat and secondary cooling water ．The influence of different factors on the heat transfer process of continuous casting solidification was analyzed．
