용선의 탈황방법Desulfurization Method of Charter

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명에서 이용한 장치의 개략도.1 is a schematic diagram of a device used in the present invention.

제2도는 비교방법과 본발명을 적용한 후의 탈황율변화를 나타내는 그래프.2 is a graph showing the change in desulfurization rate after applying the comparative method and the present invention.

제3도는 스라그두께(스라그잔류량)에 따른 탈황율의 변화를 나타내는 그래프.3 is a graph showing the change of the desulfurization rate according to the slag thickness (slag residue).

Claims (1)

혼선차 또는 래들등에 용선을 수선한 다음 인젝션법에 의하여 탈황처리하는 용선의 탈황방법에 있어서, 상기 혼선차 또는 래들내의 용선중에 텐스를 침적시켜 캐리어 가스만을 취입하여 굳어진 스라그를 용체화시켜 배제시킨 다음, 인젝션법에 의해서 1차로 탈황처리하고, 랜스를 다시 침적시켜 캐리어가스만으로 취입하여 용선과 미반응 탈황제간의 탈황반응에 의하여 2차로 탈황처리하는 것을 특징으로 하는 용선의 탈황방법.In the molten iron desulfurization method in which the molten iron is repaired in a cross-car or ladle, and then desulfurized by the injection method, the molten slag is dissolved by injecting only a carrier gas by depositing a tense in the molten iron in the cross-car or ladle. Next, the desulfurization method of the molten iron, characterized in that the primary desulfurization treatment by the injection method, the lance is deposited again, blown only with the carrier gas and desulfurization secondary by the desulfurization reaction between the molten iron and the unreacted desulfurization agent. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
