Abstract
본 발명은 제강공정에서 부산물로 발생되는 슬래그의 개질처리 방법에 관한 것이며, 그목적은 다양한 용도로 이용할 수 있는 슬래그를 제공함에 있다. 본 발명은 제강공정에서 부산물로 발생되는 슬래그의 처리 방법에 있어서, 상기 제강 슬래그를 1차로 환원처리 하거나 또는 환원처리된 개질 슬래그 생석회 및 형석을 단독 또는 복합 첨가하여 2차 개질처리하여 탈황능이 우수한 정련용 플럭스를 제조할 수 있는 슬래그 개질 처리방법에 관한 것을 그 기술적 요지로 한다.The present invention relates to a method for reforming slag generated as a by-product in the steelmaking process, the object of which is to provide a slag that can be used for various purposes. In the present invention, in the method for treating slag generated as a by-product in the steelmaking process, the steelmaking slag is first reduced or the refining slag quicklime and fluorspar are added alone or in combination to further refine the desulfurization ability. The technical gist of the slag reforming treatment method for producing the flux for the use is made.
