精炼剂对钢水脱硫处理效果的影响

Effect of Desulfurization of Liquid Steel with the Refining Flux

摘要: 在实验室和转炉炼钢厂对钢水分别用CaO-Al₂O₃精炼剂和电石型精炼剂进行精炼处理,研究了精炼剂加入量对钢水脱硫率以及钢中总氧含量的影响,钢水经过CaO-Al₂O₃精炼剂处理后,可以获得20%-40%的脱硫率:钢水经电石型精炼剂处理后,可以获得40%的脱硫率,而且钢中总氧含量可以降低到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.
