氧气转炉生产低磷镇静钢时常采用双渣掭作法,转炉生产率和金属收得率因之降低。日本住友金属工业公司和歌山钢厂为解决此问题而发展了铁水脱磷工艺。试验在40吨铁水包中进行。铁水被机
Oxygen converter production of low-phosphorus killed steel often use double slag 掭 practice, converter productivity and metal yield thus reduced. Japan Sumitomo Metal Industries Wakayama Iron and Steel Company to solve this problem and the development of molten iron dephosphorization process. The test was carried out in 40 tons of ladle. Hot metal is machine
