Zusammenfassung:	PROBLEM TO BE SOLVED: To make it difficult for the spitting granular irons as the stuck metal to stick to a furnace opening hole part. SOLUTION: In a blowing method into a converter by performing oxygen-blowing from a top-blown lance 7 into the top-bottom blown converter, the oxygen-feeding velocity for blowing the oxygen from the top-blown lance 7 is adjusted based on superficial velocity of the waste gas.
