Abstract: 

A heat transfer and solidification model based on the finite element method, validated by pin-shooting tests was created to predict the end-of-solidification state of various steel grades. Based on model and factory tests, favorable FEMS (Final Electromagnetic Stirring) modes have been determined, implemented for the best internal quality of bloom castings, in accordance with the solid fraction. The results show that the FEMS can play an obvious role in driving the residual melt and equiaxed grains in the direction of circular stirring if implemented correctly. It has been established that under optimal conditions for the implementation of FEMS, the central solid fraction should be in the range from 0 to 0.2 (0C/0C) to significantly improve the internal quality of the studied steel grades.
