Abstract
According to the production practice of 14 tons flat ingot, the influence of heat preservation measures on solidification state of ingot head is analyzed by the software ProCAST. The results show that the heating riser and electromagnetic heating riser delay the cooling of molten steel in the ingot head, but these heating risers have little effect on the temperature of the middle and lower parts of the ingot. Due to the different influence of corner heat transfer, the solidification time of molten steel in wide side is longer than that in narrow side. In comparison, the solidification time of the ingot head with electromagnetic heating riser is the longest.
