攀枝花钒钛铁水是低硅、高磷硫铁水,同时由于高炉原料(焦碳)含硫量逐年增加.因此,进入生铁中的硫有日益增高的趋势,但高炉或转炉的脱硫负担,在经济上和技术上都是不合理的,甚至是不可能的.因此,实现铁水预处理后,对于改变攀钢的品种结构会起到有力的推动作用.为此,我们于1980年自行设计、制造了一套喷吹法脱硫装置并于1981年进行了工业性试验,通过对设备不断改进和完善,喷吹系统运转正常,并具有较满意的喷吹效果.
The vanadium-titanium molten iron in Panzhihua is low-silicon and high-phosphorous sulfur and hot metal, and the sulfur content of raw materials (coke) in blast furnaces increases year by year. Therefore, the sulfur content in pig iron increases with increasing trend. However, And technically unreasonable, or even impossible.Therefore, after the realization of hot metal pretreatment, to change the variety structure of Panzhihua Iron and Steel will play a powerful role in promoting.To this end, we designed and manufactured in 1980 A set of injection desulfurization plant and in 1981 conducted an industrial test, through continuous improvement and improvement of equipment, injection system is operating normally, and has a more satisfactory injection effect.
