精煉劑對鋼水脫硫處理效果的影響

Effect of Desulfurization of Liquid Steel with the Refining Flux

摘要: 在實驗室和轉爐煉鋼廠對鋼水分別用CaO-Al₂O₃精煉劑和電石型精煉劑進行精煉處理,研究了精煉劑加入量對鋼水脫硫率以及鋼中總氧含量的影響,鋼水經過CaO-Al₂O₃精煉劑處理后,可以獲得20%-40%的脫硫率:鋼水經電石型精煉劑處理后,可以獲得40%的脫硫率,而且鋼中總氧含量可以降低到5×10^-5以下。

Abstract: The liquid steel was refined in the laboratory and in converter steel shop with the mixture of CaO-Al₂O₃ and Cao-Al₂O₃-CaC₂. The influence of the mixture added amount on the desulfurization and total oxygen of steel has been investigated. Refinin of steel with the mixture of Cao-Al₂O₃, the desulfurization of 20%~40% was reached; Refining of steel with the mixture of CaO-Al₂O₃-CaC₂, the desulfurization of 40% was reached, and the total oxygen in the steel was reduced under 5×10^-5.
