氧气转炉炼钢法的出现,已经有20多年了,已被各国广泛采用。而化渣操作至今仍是炼钢工艺中研究的重要课题。炼钢工作者最初从研究改进喷嘴结构和喷枪操作入手来改善化渣进程,取得了一定的成就,但理论和实践证明这并不能解决石灰本身的熔解能力问题。近年来,关于改进石灰质量提高它在炉 Oxygen converter steelmaking law has emerged for more than 20 years, has been widely adopted by all countries. The slag operation is still an important issue in the steelmaking process. The steelmakers initially improved the slag removal process by studying the improvement of the nozzle structure and the operation of the spray gun. Some achievements have been made. However, the theory and practice have proved that this does not solve the problem of the melting ability of the lime itself. In recent years, it has been about improving the quality of lime in furnaces
