转炉在冶炼硅钢、不锈钢、高强度钢或者进行炉外精炼时,使用挡渣技术是不可缺少的.它有提高合金效率、避免出钢过程回磷、减少钢渣对钢液的污染、提高钢液的纯度、提高钢包寿命和提高炉外精炼效果等作用.目前的挡渣方法较多,挡一次渣法有的用挡渣帽,有的用代渣槽的钢包车.挡二次渣法有挡渣球,挡渣塞,挡渣包,还有采用U型出钢口.但目前国内外较广泛应用的是挡渣球和挡渣塞.因为它们不需要对炉子进行改造和增加复杂的设备,只需要一个简单的投球设备.攀钢炼钢厂未进行一次挡
Converter in the smelting of silicon steel, stainless steel, high-strength steel or refining outside the furnace, the use of slag technology is indispensable. It has to improve the efficiency of the alloy to avoid tapping during the process of phosphorus to reduce the slag on the molten steel to improve the molten steel The purity of the ladle to improve the life and improve the effect of refining the role of the furnace and so on.Currently the slag-blocking method more, block a slag method with some slag cap, and some use of slag tank ladle car. Slag block, slag block, slag package, there U-shaped tapping, but more widely used at home and abroad is the slag and the ball-block plug because they do not need to transform the furnace and add complex Equipment, just a simple pitching equipment. Panzhihua Iron and Steel did not do a block
