LADLE-REFINING METHOD AND LADLE-REFINING FURNACE

机译:钢包精炼方法和钢包精炼炉

摘要

PROBLEM TO BE SOLVED: To provide a method for surely achieving floatation separation of inclusions and for suitably performing desulfurization in a ladle-refining furnace which is considered as the disadvantage, regarding floatation separation of fine inclusions in the conventional method.;SOLUTION: When molten steel in the ladle-refining furnace is refined by stirring with usages of both the blowing of an inert gas from the bottom part of the ladle and the electromagnetic stirring, during degassing treatment, the molten steel fluidization with the electromagnetic stirring is introduced so as to ascend along the inner wall of the ladle and descend in the inert gas ascending area.;COPYRIGHT: (C)2007,JPO&INPIT
