Abstract

본 발명은 제강공정중에서 전로 출강중 용강에 존재하는 산소를 제거할 때 사용되는 탈산제로 용강탈산으로 고융점의 탈산 생성물을 저융점의 개재물로 제어함으로써 용강의 청정도를 향상시키는 것이다.The present invention improves the cleanliness of molten steel by controlling the deoxidation product of high melting point with the inclusion of low melting point by using molten steel deoxidation as a deoxidizer used when removing oxygen present in molten steel during the steelmaking process.

본 발명의 알루미늄 탈산가의 청정강 제조용 탈산제은 선로 출강시 용강을 탈선하는 처리재에서 고청정강을 제조할 목적으로, 알루미늄이 14-32%, 레이들 슬래그는 68-86%가 혼합된 용강 탈산제를 사용하는 것을 특징으로 하는 제조법.The deoxidizer for manufacturing clean steel of aluminum deoxidizer of the present invention is a molten steel deoxidizer in which 14-32% of aluminum and 68-86% of ladle slag are mixed for the purpose of manufacturing high-purity steel from a treatment material which derails molten steel when the rail is pulled out. A manufacturing method characterized by using.
