Abstract：Compared and analyzed the single and double slag method on aspect of material consumption and dephosphorization effect on the 120 t converter in Jiuquan Steel. The result shows:the average of lime consumption for double slag smelting is 3 416 kg, lower than 3 583 kg for single slag smelting;the average of dolomite consumption is 1 200 kg, lower than 1 600 kg for single slag smelting;the average of total charging accessories is 7 405 kg, lower than 8 072 kg for single slag smelting. The average of phosphorus content is 70×10-6, significantly lower than 140×10-6 for single slag smelting. Under the similar condition of dolomite consumption and iron losses, the average of lime consumption for double slag smelting is saved nearly 10 kg/t. The total slag quantity is also lower than single slag method.
