Abstract

본 발명은 일관제철 공정에서 부산물로 발생되는 고로슬러지, 전로 슬러지 및 기타 함철 더스트류를 배합하여 펠릿(pellet)화 한 것을 저온의 공정폐열만을 이용하여 원료자체에 함유된 열원물질을 연소시킴에 의해 소성하는 방법으로서 제강용 전로 및 코렉스(corex)의 장입물로 이용할 수 있는 폐자원 활용방법에 관한 것이다·The present invention is a pelletized by mixing the blast furnace sludge, converter sludge and other iron-containing dusts generated as a by-product in the integrated steelmaking process by burning the heat source material contained in the raw material itself using only low-temperature process waste heat As a method of firing, the present invention relates to a method of utilizing waste resources that can be used as a steelmaking converter and a corex charge.

본 발명의 함철 극미분 더스트류의 소성방법는 제철공정에서 폐기되는 부산물 중 전로슬러지 45∼40%, 고로슬러지 35∼30%, 자철계 분량 20∼30%의 비율로 배합하여 제조한 펠릿을 약 400℃의 외부 열원만을 공급하여 펠릿을 구성원료 자체에 함유된 열원물질이 연소되게 함으로써 펠릿의 견고하게 소성한다.The firing method of the ultra-fine iron dust dust of the present invention is about 400 to 40 of the pellets prepared by mixing the ratio of converter sludge 45 to 40%, blast furnace sludge 35 to 30%, magnetite 20 to 30% by-products discarded in the steelmaking process The pellet is firmly calcined by supplying only the external heat source at 占 폚 to cause the pellet to burn the heat source material contained in the member material itself.
