摘要：
PURPOSE: A method of controlling temperature of melts using coke in place of ferro silicon during steel refining is provided. CONSTITUTION: In a steel refinement including top blowing, the method is characterized in that coke is poured into molten steel in an amount of 3 to 7 kg·coke/t·molten steel at such stage that top blowing is processed as much as 60 % from initial blowing stage in the case that C/(A-B) is less than 82 %, where A is total amount of molten metal, B is the amount of scrap to be charged, and C is the amount of hot metal.
