REFRACTORY COOLING METHOD FOR REFINING CONTAINER

摘要

PROBLEM TO BE SOLVED: To sharply reduce the cooling time of a refractory without causing sporing and wetting of a refractory of a refining container. SOLUTION: Since the temperature of a refractory of a refining container is high, cooling time of the refractory can be sharply reduced without causing sporing and wetting of the refractory by controlling as mixing ratio of water and air for mist cooling to a proper range.
