摘要： The present invention relates to a method for reusing an iron-containing by-product and an apparatus therefor and, more specifically, to a method for reusing an iron-containing by-product, comprising the steps of forming a briquette by mixing an iron-containing by-product with 5-20 parts by weight of carbon per 100 parts by weight of the iron-containing by-product, pre-reducing the briquette at 800-1300°C, and charging the pre-reduced briquette into an electric furnace, and to an apparatus for reusing an iron-containing by-product, comprising a reducing furnace for pre-reducing, at 800-1300°C, a briquette formed by mixing an iron-containing by-product with 5-20 parts by weight of carbon per 100 parts by weight of the iron-containing by-product, and an electric furnace into which the pre-reduced briquette is charged. The present invention can reduce the cost of treating industrial waste by recycling an iron-containing by-product, such as electric furnace dust which is an environmentally regulated substance discharged from an electric furnace, and can simultaneously contribute to reducing the cost of molten steel production by reusing the iron-containing by-product as a raw material for an electric furnace. In addition, the present invention can substitute for the function of a combustion facility for removing dioxin or carbon monoxide contained in the exhaust gas of an electric furnace, thereby inducing the effect of additional cost reduction.
