    • PURPOSE: A method of preventing slag from peroxiding in an electric furnace is provided to enhance refining of slag and to activate slag forming in a refiner as well as to minimize iron oxide through reduction. CONSTITUTION: In working at an electric furnace, a slag manufacturing material is prepared by mixing caustic lime and coke to ladle slag. The slag manufacturing material is injected to prevent peroxidation of electric furnace slag and to enhance the real yield rate of a ladle. The added caustic lime is mixed in a range of meeting CaO/SiO2 ratio to 4 considering the CaO density, and the coke is mixed under 30% and processed as pellet or briquette.
    • 目的:提供一种防止炉渣在电炉中过氧化的方法,以增强炉渣的精炼和活化精炼炉中的炉渣形成以及通过还原使氧化铁最小化。 组成:在电炉工作时,通过将苛性石灰和焦炭与钢包渣混合来制备炉渣制造材料。 注入炉渣制造材料以防止电炉炉渣的过氧化并提高钢包的实际成品率。 考虑到CaO密度,将添加的苛性石灰在满足CaO / SiO2比为4的范围内混合,并且将焦炭在30%以下混合并且作为丸粒或型煤加工。
