本文,从冶金和经济观点出发,对铁水炉外脱硫所用的碳化物喷射和镁饱和焦碳处理法作了比较。两种方法的比较是以(Norrbottens Jarnerk AB厂的)300吨鱼雷式混铁车和70吨敝包处理铁水的实验为基础的。处理前铁水的硫含量很高(0.10％)。作者得出了若干结论,这些在下面列举。为了减少脱硫剂的耗量,当碳化物喷射时,要注意检查喷枪的最大 This article, from a metallurgical and economic point of view, compares the carbides spray and the magnesium-saturated coke process used for desulfurization in a hot metal ladle. A comparison of the two methods is based on experiments with a 300-tonne torpedo (Norrbottens Jarnerk AB plant) and a 70-tonned masterbatch for hot metal. The hot metal content before treatment was high (0.10%). The authors reached a number of conclusions, these are listed below. In order to reduce the desulfurization agent consumption, when the carbide spray, pay attention to check the gun maximum
