Direct reduction of carburized pre-reduced pellets by microwave heatingHU Bing(胡兵)1, 2, HUANG Zhu-cheng(黄柱成)1, YI Ling-yun(易凌云)1, JIANG Tao(姜涛)1(1. School of Minerals Processing and Bioengineering... carbon not only acts reaction as a reduction agent, but also absorbs microwave in the reduction process. Hence, the carburized pre-reduced pellets can be rapidly reduced by microwave heating......
