Title:
溶鋼の鋳造方法、連続鋳造鋳片の製造方法及び軸受用鋼材の製造方法
Document Type and Number:
Japanese Patent JP6969707
Kind Code:
B2
Abstract:
There are provided a method for casting molten steel, a method for producing a continuously cast piece, and a method for producing a steel material for a bearing, that can suppress a gas-liquid reaction between molten steel and oxygen in the air. A method for casting molten steel using a continuous casting facility includes: a replacement step of blowing a replacement gas containing at least a combustible gas into a tundish (1) under an incomplete combustion condition to replace a gas in the tundish (1), the tundish (1) being an intermediate vessel in the continuous casting facility; and after the replacement step, a casting step of stopping blowing the replacement gas and performing continuous casting in the continuous casting facility by using the tundish (1) without blowing the replacement gas into the tundish (1).
