摘　　要：介绍了原煤替代部分兰炭,在18 MW硅铁矿热炉试验。通过对原料质量的检测,分析配煤方案的可行性,两个阶段性的试验虽然电耗升高、生产指标下滑,但为后续硅铁炉料使用积累了经验。It introduces the test of replacing part of semi-coke with altogather coal in 18 MW ferrosilicon submerged arc furnace.The feasibility of the coal blending scheme is analyzed through the testing of raw material quality.Although the power consumption increases and the production index declines,the two stage tests accumulate experience for the subsequent use of ferrosilicon furnace charge.
