Abstract

본 발명은 황화철분말과, 산화제 2철을 포함하는 중량재 본말과를 균일하게 혼합한 탈산제를 금속용탕중에 투입하는 것을 특징으로 한 금속용탕의 탈산방법에 관한 것이다.The present invention relates to a deoxidation method of a molten metal, characterized in that a deoxidizing agent, which is a mixture of an iron sulfide powder and a heavy material containing a ferric oxide, is added into a molten metal.

상기 황화설분말과, 산화제 2철을 포함하는 중량재분말은 금속용탕의 0.3%∼0.5%(중량)로 한다. 또 본 발명은 황화철분말과, 산화제 2철을 포함하는 중량재 분말을 균일하게 혼합한 탈산제에 관한 것이다.The heavy ash powder containing the sulfide sulfide powder and ferric oxide is made 0.3% to 0.5% (weight) of the molten metal. Moreover, this invention relates to the deoxidizer which mixed the iron sulfide powder and the weight material powder containing ferric oxide.

이 탈산제를 사용하면 탈산효과가 현저할 뿐만 아니라 탈산 생성물이 잔류하여도 제품의 품질에 악영향이 발생하지 않는 효과가 있다.When the deoxidizer is used, not only the deoxidation effect is remarkable but also the deoxidation product remains, which does not adversely affect the quality of the product.
