METHOD FOR STIRRING MOLTEN METAL BY IMPELLER

摘要

PROBLEM TO BE SOLVED: To provide a method for stirring molten metal using an impeller which suppresses the splashing of the molten metal and the erosion of refractories and does not impair the reaction efficiency of the molten metal and additives. SOLUTION: The impeller is rotated while the immersion depth, rotating diameter and number of revolutions of the impeller are maintained in adequate ranges.
