摘　　要：碳质还原剂占工业硅生产成本的25％～35％，合理选择碳质还原剂可降低能耗和生产成本，对提高产品质量起到至关重要作用。论文介绍了工业硅冶炼对碳质还原剂的选择要求，对工业硅常用碳质还原剂的应用现状及国内外关于工业硅生产用新型碳质还原剂的研究成果进行了综述。The carbon reducing agent accounted for 25% - 30% of the total cost of metal silicon production. Production costs and energy consumption will be reduced by using the reasonable carbon reducing agent,and it also be beneficial to improve product quality effectively. The basis of selection carbon re- ducing agent in metal silicon production process is reviewed. The current situations of application of the reducing agent are introduced. And several re- search achievements about carbon reducing agent are introduced.
