摘要

摘要研究了在锰铁生产中，焦炭和烟煤对中锰矿石还原的影响。30公斤中等品位锰矿石、12公斤石灰石和不同数量的焦炭和煤在1300°C至1500°C的埋弧炉(SAF)中熔炼。用x射线荧光法测定了锰铁和渣的组成。结果表明，用焦炭作单一还原剂，锰铁收率达96%，高于用煤作单一还原剂或煤与焦炭混合还原剂。还发现，使用焦炭作为单一还原剂的比能量消耗最低。以煤为还原剂生产高硫高磷锰铁。

Coke and coal as reductants in manganese ore smelting: An experiment

Abstract The effect of coke and bituminous coal on the reduction of medium-grade manganese ore in ferromanganese production was investigated. Charges of 30 kg medium grade manganese ore, 12 kg limestone and varied amounts of coke and coal were smelted in a Submerged Electric Arc Furnace (SAF) at temperatures of 1300°C to 1500°C. The composition of the ferromanganese and the slag were determined by X-Ray Fluorescence. It was found that using coke as a single reductant resulted in a 96% yield of ferromanganese which was higher than by using coal either as a single reductant or in a mixture of coal and coke. It was also found that using coke as a single reductant resulted in the lowest specific energy consumption. Using coal as reductant produced ferromanganese containing high sulfur and phosphorus.
