铁水预脱硫喷吹系统的优化设计

Optimum Design of Injection System for Predesulphurization of Hot Metal

根据铁水预脱硫工艺和喷吹技术发展状况，结合实践经验，从铁水预脱硫喷吹系统设计的角度出发，对铁水预脱硫工艺、脱硫剂喷吹方式、操作方式、粉气比大小及喷吹控制方式的优化设计做一些有益的探讨。实践表明。

Based on the development status of desulphurizatin process of hot metal and injection technology, putting emphasis on the design of predesulphurization and injection system, this paper gives discussions on some aspects, such as predesulphurization process of hot metal, injection methods of desulphurizing agents ,operation patterns, ratio of powder and gas, and the optimum design of injection control. It is proved by practice that the optimum design has brought good effects.
