DOC《废弃碳材料对工业硅冶炼的影响研究》

3 结论 本试验在8MVA的小型埋弧式电弧炉进行,以一种废弃碳材料替代20%左右的碳质还原剂用于工业硅生产.通过评估试验前中后期三个阶段的冶炼情况,结果显示:试验期间工业硅回收率达到最高0.945,平均吨硅的电力消耗低于试验前期和后期;

在产品质量方面,Al的含量降幅达到19.089%以上,Ca的含量降幅达到15.060%,Cr和Ni的含量降幅分别达到18.310%和12.195%,但产品的Fe、P含量有些许增加,Ti含量也有极少量增加;

在碳排放方面,试验期间生产每吨工业硅减少CO2排放达到了0.865t. 参考文献 [1] KARALI N, XU T, SATHAYE J. Reducing energy consumption and CO2 emissions by energy efficiency measures and international trading: A bottom-up modeling for the U.S. iron and steel sector[J]. Applied Energy, 2014,
