日本新日铁公司大分钢铁厂最近采用了一种喷粉生产超低硫钢的方法。该厂所安装的钢水罐喷粉设备具有喷粉能力大、处理时间短的特点。该厂喷粉设备的容量为340t,所喷吹的粉剂为 Ca-Si 合金粉和 CaO+CaF_2粉,喷吹速度为100～250kg/min。喷粉时喷枪插入罐内钢水中的深度为2000～3000mm。喷粉时以 Ar作运载气体,Ar 的流速为1000～3000NL/min。
Japan’s Nippon Steel Company Oita Steel Works recently adopted a method of powdering to produce ultra-low-sulfur steel. The plant installed steel tank dusting equipment with dusting capacity, short processing time characteristics. The factory dusting equipment capacity of 340t, the blowing powder is Ca-Si alloy powder and CaO + CaF_2 powder, blowing speed of 100 ~ 250kg / min. Dusting gun into the tank when the depth of molten steel 2000 ~ 3000mm. Ar powder as the carrier gas, Ar flow rate of 1000 ~ 3000NL / min.
