ABSTRACT:
A method for treating molten steel utilizing an induction coil, a ladle, a treating vessel and at least one passage pipe interconnecting the ladle and the treating vessel which includes the steps of lifting up a part of the molten steel from the ladle to the treating vessel disposed over the ladle through adjustment of molten steel composition and/or degassing in the treating vessel, thereafter returning the molten steel to the ladle through the at least one passage pipe, circulating or reciprocating the molten steel between the ladle and the treating vessel while heating the molten steel by the induction coil disposed around the at least one passage pipe and operating the linear motor at a frequency of 50 to 60 cycles.
