J. Cent. South Univ. (2016) 23: 1318-1325 DOI: 10.1007/s11771-016-3182-1 Reduction mechanism of Fe2O3-Cr2O3-NiO system by carbon ZHANG Yan-ling(张延玲), GUO Wen-ming(郭文明), LIU Yang(刘洋), JIA Xin-lei(贾昕磊... of the reduction. Factors such as temperature, carbon content, sample size have a more significant effect during the final stage (α>38%). The metallic product formed at the initial stage (a Fe-Ni alloy) greatly......

J. Cent. South Univ. (2012) 19: 1813-1816 DOI: 10.1007/s11771-012-1213-0 Carbothermic reduction of alumina with carbon in vacuum YU Qing-chun(郁青春), YUAN Hai-bin(袁海滨), ZHU Fu-long(朱富龙), ZHANG... and carbon decreases gradually with increasing time. Meanwhile, lower system pressure or higher temperature is beneficial to the carbothermic reduction of alumina process. Al4O4C is firstly formed......
. In order to further interpret reaction mechanism, different reaction models were constructed. It was revealed that not only the carbon content could affect the Cr(VI) reduction, but also the carbon structure had an important effect on its reduction. Key words: relative high concentration Cr(VI); reduction; ZVI powder; carbon content; carbon structure Cite this article as: LV Jin-fang, TONG Xiong......
into the prereduced ilmenite with carbon was more obvious with reduction degree increasing owing to the high porosity of prereduced ilmenite. Key words: molten iron; prereduced ilmenite; wetting; interfacial permeability; contact angle; carbon reduction ......
