斯万斯克钢公司最近投产了一台向铁水中喷吹粉末的脱硫设备,以便得到含硫量低的高质量钢。以前采用的方法是向鱼雷罐和移动铁水包中添加碳酸钠,这样脱硫后的铁水含硫量不低于0.020％.最近该公司建立了一个新的脱硫车间,经脱硫后的铁水用于炼钢,在吹氧以后,不经任何特殊处理,就能得到硫含量低于0.005％的钢水。 Swansk Steel recently commissioned a desulfurization plant that blows powder into molten iron to get high quality steel with low sulfur content. Previously used method was to add sodium carbonate to torpedo cans and moving ladle so that the desulfurized hot metal had a sulfur content of not less than 0.020% Recently, the company established a new desulphurization plant and the desulphurized hot metal is used for refining Steel, after oxygen blowing, can be obtained without any special treatment of sulfur content of less than 0.005% of the molten steel.
