生产碳素镇静钢一般都采用铝进行最终脱氧,不仅消耗量很大,而且对资源利用也不尽合理。由于纯铝的比重较小,出钢时直接加入盛钢桶内,往往会浮在钢水表面,造成铝的大量燃烧或与熔渣相混,使铝的回收率显著降低。同时由于钢中的铝含量波动很大,对钢材的性能也有直接的影响。为了提高铝的回收 The production of carbon-killed steel generally uses aluminum for ultimate deoxidation, which not only consumes a lot but also makes unreasonable use of resources. Due to the small proportion of pure aluminum, the steel directly into the ladle when tapping, often floating on the molten steel surface, resulting in a large number of aluminum or slag mixed with the slag, the aluminum recovery rate was significantly reduced. At the same time as the aluminum content in steel fluctuates greatly, the performance of steel also has a direct impact. In order to improve the recovery of aluminum
