一、前言向钢包喷吹惰性气体进行搅拌,同时吹入精炼剂进行钢液的二次精炼,是近几年发展起来的炉外精炼的新工艺[1—3]。实践证明:良好而稳定的钢包喷粉处理效果,主要取决于喷粉处理的主体设备——分配器,及合理的喷吹工艺参数。对这些工作的深入试验研究,是瑞典等国家在发展喷射冶金技术方面所取得成绩的重要原因[4—6]。八○年我厂从 First, the foreword ladle inert gas injection ladle, while blowing refining agent secondary refining of molten steel is developed in recent years, a new furnace refining technology [1-3]. Practice has proved that: good and stable ladle dusting treatment effect, mainly depends on the main equipment of the powder processing - distributor, and a reasonable injection process parameters. An in-depth experimental study on these tasks is an important reason for the achievements made by Sweden and other countries in the development of jet metallurgy technology [4-6]. 80 years I plant from
