在攀钢120t转炉出钢时根据终点碳含量的不同,出钢前在钢包内加入不同数量自行发明的P_1脱氧剂,然后用自行研制的W—Ⅱ型钢包喂线机将曰10mm的铝线以8～10m/s的速度喂入钢包,取得了铝收得率比传统投入法提高4.2倍(低碳钢)和2.5倍(高碳钢),钢中夹杂物减少,硅锰收得率提高3.5％以上,防止回硫甚至可部分脱硫的综合冶金效果。 In Panzhihua Iron and Steel 120t converter tapping steel according to the end of the carbon content of the different tapping in the ladle before adding a different amount of self-invented P_1 deoxidizer, and then developed its own W-Ⅱ ladle feeder will say 10mm aluminum The ladle was fed at the rate of 8 ~ 10m / s, and the aluminum yield was improved by 4.2 times (mild steel) and 2.5 times (high carbon steel) than that by the traditional method. The inclusions in the steel decreased, Increased by 3.5%, to prevent the sulfur can even be partially desulfurization of the comprehensive metallurgical effect.
