一九八一年我厂围绕着增加品种、提高质量、降低消耗、提高炉龄等方面作了一些工作,取得一定的进展,现就工艺方面的情况简述如下。 一、喷吹法炉外脱硫试验 攀钢系采用钒钛磁铁矿冶炼,高炉脱硫能力低,供炼钢用的钒钛铁水含硫高,给转炉冶炼带来困难,产品品种、质量都受到限制。为此,建立了罐内顶喷脱硫工业性试验装置,于81年进行了三个阶段的试验,共在140吨铁水罐内进行了46次试验。每次处理铁水量80～110吨,脱硫效率最高达92.9％,最低终点含硫量可降到0.005％以下。
In 1981, our factory made some efforts to increase variety, improve quality, reduce consumption and improve furnace age. Some progress has been made. The process of the process is briefly described as follows. First, the injection furnace desulfurization test Panzhihua Iron and Steel Department of vanadium titanium magnetite smelting, blast furnace desulfurization capacity is low for the steel with vanadium and titanium hot metal high sulfur content, to the converter smelting difficulties, product variety, quality are subject to limit. To this end, a top-spray desulfurization industrial pilot plant has been established and conducted in three stages in 81 years with a total of 46 tests conducted in a 140-tonne hot metal tank. Each treatment of molten iron 80 ~ 110 tons, desulfurization efficiency up to 92.9%, the lowest endpoint sulfur content can be reduced to 0.005% or less.
