15t steel ingots of different amount of exothermic powder were under computer simulation analysis by casting simulation software with the distribution of shrinkage cavity predicted. The results showed that, with increasing adding of exothermic powder, the final solidification high temperature area moves from the main body of the ingot onto the riser area, so that the riser can feed the shrinkage cavity very well. The simulation result agrees with validation experiments very well. It indicates that the optimized adding suitable amount of exothermic powder in riser area can effectively eliminate the shrinkage cavity, and enhance the steel ingots’ quality and the ration of utilization.
