摘要： PROBLEM TO BE SOLVED: To charge a wire-like alloy and a powder-like alloy into a molten steel without being exposed to air or slag by disposing an alloy charging pipe in an oxygen flow passage of a lance and/or a cooling water passage. SOLUTION: A steel lance pipe 10 for charging is disposed in a middle cylinder 62 which is a cooling water passage, and a powder-like alloy or a wire-like alloy is passed through a lance pipe 11 for charging. Since the lance pipe 10 for charging is cooled with cooling water flowing in the middle cylinder 62, it can fully withstand even when it is exposed to the high temperature. Since no unevenness is present on an inner wall of the pipe, the wire-like alloy is not hooked when it is inserted therein, and can be smoothly charged into the molten steel (in the direction of an arrow C). Since the alloy charged from the lance pipe 10 for charging is carried together with oxygen ejected from an inner cylinder 61 (in the direction of an arrow A) to the molten steel, even the powder-like alloy can be forcibly charged into the molten steel against the upward air flow from the molten steel.
