摘　　要：对粒铁脱碳机理进行了分析 ,并对粒铁脱碳工艺流程和脱碳粒铁进行了技术评价。结果表明 ,在脱碳粒铁质量、建设投资、生产成本、生产规模可变性、操作难易程度、生产效率和对原材料的要求等方面 ,粒铁脱碳技术都比用直接还原法生产海绵铁或用其它途径更为合理和容易实现。脱碳粒铁可作为电炉的常规炉料 。In order to solve the problem of scrap shortage, especially high quality scrap, a new substitute for scrap or DRI has been developed. The decarbonization mechanism of granular pig iron has been analyzed, and the technical process and decarbonized granular pig iron have been evaluated. The research results showed that the decarbonized technique is superior to direct reduction process in product quality, construction investment, operation flexibility, production efficiency etc. Decarbonized granular pig iron not only can be used as conventional scrap but also can be charged into EAF as high purity burden equivalent to DRI and heavy scrap.
