摘　　要：以K_2CO_3作为添加剂,研究了添加剂对工业硅矿热炉冶炼过程电耗以及各种原料消耗的影响。通过对比试验前中后三个时期发现,添加剂的添加改善了还原剂的反应性能,保证了电极下插深度,有利于实现工业硅强化熔炼过程。该试验结果对目前存在的还原剂问题具有重要的意义。The effect of K 2CO 3 as additive on the energy consumption and raw materials consumption of industrial grade silicon production process was investigated.By comparing the three periods of the earlier,the medium and the later of the experiment,it found that the activity of carbonaceous reductants was improved by the additive,and ensured the insertion depth of electrode.Thus,it can help the process of industrial grade silicon strengthening smelting.It is of great significance for the present problems of carbonaceous reductants.
