一、前言近代冶金生产发展的主要特征是:努力提高冶金设备的生产效率和技术指标;改善钢的质量和降低钢的成本。由于喷射冶金的反应面积大、速度快、效果好、费用低,正适合了这种要求,因此得到迅速的发展。喷射冶金用于脱[S]、脱[O]及改变夹杂物形态,已显示出明显的效果。但是,增[H]、增[N]及产生大颗粒夹杂却成了目前发展中的主要障碍。所以,研究、开发具有
I. Introduction The main features of the development of modern metallurgy production are: efforts to improve metallurgical equipment production efficiency and technical indicators; improve the quality of steel and reduce the cost of steel. Due to the reaction area of jet metallurgy, fast, effective, low cost, is suitable for this requirement, it has been rapid development. Spray metallurgy has been used to remove [S], off [O] and change the morphology of inclusions, which have shown obvious effects. However, increasing [H], increasing [N] and generating large grain inclusions have become the major obstacles in the current development. So, research, development has
