    • PURPOSE: A method for reducing slag is provided to increase a reduction effect with injecting an optimal reducing agent inside the slag from an iron making process and a steel making process, thereby increasing a recovery amount of a valuable metal inside the slag. CONSTITUTION: A method for reducing slag includes: a step (100) of reducing the slag from melting scraps in an electric furnace, identifying the components of the slag which is a subject for reduction, and then determining a desired composition ratio after the reduction; a step (200) of determining a mixing ratio and injecting amount for a composite reducing agent in which multiple reducing agents are mixed according to the desired composition ratio; and a step (300) of injecting the composite reducing agent inside the melted slag in order to reduce the slag. [Reference numerals] (100) Step of setting a desired composition ratio; (200) Step of determining a composite agent; (300) Step of returning a slag
    • 目的:提供一种减少炉渣的方法,通过在炼铁过程和炼钢过程中从矿渣中注入最佳还原剂来提高还原效果,从而提高炉渣内有价值金属的回收量。 构成:还原渣的方法包括:将炉渣从电炉熔融渣中还原的步骤(100),鉴定作为还原剂的炉渣成分,然后确定还原后的所需组成比; 确定根据所需组成比混合多种还原剂的复合还原剂的混合比例和注入量的步骤(200); 以及将复合还原剂注入熔融炉渣内部以减少炉渣的步骤(300)。 (附图标记)(100)设定所需组成比的步骤; (200)确定复合剂的步骤; (300)回炉的步骤
