Abstract
본 발명은 제강공정중 전기로에서 출강후 수강래이들에서 슬래그를 탈산하기 위해 사용되는 슬래그 탈산제에 관한 것이다. 본 발명의 청정강제조용 슬래그 탈산제는 중량%로 CaO가 36-59%, Al2O3가 41-64%인 용융산화물에 금속 알루미늄: 1-50% 첨가하에서 된 것을 특징으로 한다.The present invention relates to a slag deoxidizer used for deoxidizing slag in tap ladles after tapping in an electric furnace during the steelmaking process. The slag deoxidizer for clean steelmaking according to the present invention is characterized in that the metal oxide: 1-50% is added to a molten oxide having a CaO of 36-59% and Al 2 O 3 of 41-64% by weight.
