REFORMING METHOD OF STEELMAKING SLAG

摘要

PROBLEM TO BE SOLVED: To provide a technique for improving the utilization efficiency of blown gas containing oxygen in reforming of steelmaking slag by blowing of gas containing oxygen.SOLUTION: In a reforming method of steelmaking slag for reforming the steelmaking slag by blowing gas containing oxygen into molten steelmaking slag, the gas containing oxygen is blown under distribution that the total blown time is divided to at least two stages equally and the blown amount of each stage decreases as it approaches the post stage.SELECTED DRAWING: None
