日本钢管公司福山钢铁厂为降低钢中的磷、硫含量而采用了向钢水罐中添加由转炉渣及少量亚硅酸苏打所组成的脱磷剂,而使钢水进行渣洗脱磷的方法,取得了钢水脱磷率达50～70%的良好效果。该厂所用脱磷剂的成分为:约85%的低磷转炉渣和15%的亚硅酸苏打,其加入量为10kg/t 钢。采用该方法使钢水脱磷,不仅生产工艺简单,而且脱磷处理成本也比较低。如在脱磷剂中加入一定数量的苏打灰,则有可能在使钢水脱磷的同时达到使钢水
Japanese steel company Fukuyama Iron and Steel Plant to reduce phosphorus and sulfur content in the steel used to add a steel tank by the converter slag and a small amount of dephosphorizer soda composed of slag, Made of molten steel dephosphorization rate of 50 to 70% of the good results. Dephosphorization plant used in the plant components: about 85% of low-phosphorus converter slag and 15% of the Asian soda, the amount of 10kg / t steel. Adopt this method to dephosphorize the molten steel, not only the production process is simple, but also the dephosphorization treatment cost is relatively low. If the dephosphorization agent by adding a certain amount of soda ash, it is possible to dephosphorize the molten steel while reaching the molten steel
