摘要

对300 t顶底复合吹氩钢包预脱硫工艺进行几何相似比1:5.75的水模型试验结果表明

总供气量相同时

与单吹相比顶底复吹能有效提高预成渣速度

当顶底吹氩流量比为50:50

搅拌条件最好;根据水模型试验结果

在300 t钢包上建立顶、底吹氩装置

在微合金站实现预成渣脱硫

钢水平均脱硫率达22.29%

处理后平均终点[S]为0.004%

(FeO+MnO)降至3.48%。

Abstract

The test of pre-desulfurization technology7 of a 300-t top and bottom combined argon blowing ladle has been carried out by using a water model with geometric similarity 1 ：5. 75 water model. Results show that with same total gas flow

as compared with single blowing the top and bottom combined blowing could effectively increase the pre-slagging speed

and as flow rate of top-bottom argon blowing is 50 ： 50

the stirring condition is best ； based on the water model test results the top-bottom combined argon blowing installation for the 300 t ladle is established to realize the liquid pre-slagging desulfurization

the liquid average desulfurization ratio is 22. 29%

after refining the average end [S]is 0. 004% and the (FeO + MnO) decreases to 3. 48%.
