Abstract
Breakouts due to insufficient skin thickness exiting below caster mold are prevented. Minimum mold heat removal rate is defined in terms of casting speed, mold faces, mold size, material grade and tundish superheat, then calculated, indicated and compared to actual measured values of heat removal rate. As a result of the comparison, caster preset speed correction is taken to automatically maintain the mold heat removal rate above the minimum level where breakouts occur.
