| Abstract: | A three-dimensional mathematical model of solidification in large steel ingot has been developed.The solidification of a 53-ton industrial steel ingot was numerical simulated by the model as well as the commercial finite element software ProCAST.The present predictions for cooling curves at different characteristic positions in the solidifying ingot and in the mold,the total solidification time and the shrinkage cavity of the ingot were in good agreement with those calculated by ProCAST. |

| Keywords: | large steel ingot solidification temperature distribution numerical simulation |
