摘　　要：利用混铁炉倒铁水的自然搅拌动能,将含铁粉剂喷入铁水中,脱除铁水中的部分Si。通过选择合理的系统参数,优化脱硅粉剂配比,调节下料速度在10kg/s以上,并开发了喷吹脱硅自动控制系统,下料量控制精度达到了1%,保证了脱硅反应的平稳进行,脱硅剂反应充分,脱硅量0.07%。Making use of unforced agitation moving force in course of tipping molten iron, the iron powder was injected into the molten iron to remove the partial silicon in the molten iron. Through selecting reasonable parameters of the injection system, optimizing the proportioning of the desiliconization powder agent, adjusting discharge rate above 10 kg/t and developing the automatic control system for injection desilication, the control precision of discharge rate reached 1% and then the desilication reaction was calm. The desilication agent reacted fully and desilication rate was 0.07%.
