摘要
介绍了测定硅石抗爆性和还原性能的方法 ,并对测定结果进行了分析讨论。硅石的抗爆性和还原性能取决于硅石的晶粒度 ,晶粒小抗爆率高 ,还原性能好。生产得出 ,冶炼 75 %硅铁时 ,1 2 5MVA电炉使用抗爆率为 87%左右的硅石可获得较好的技术经济指标。
It introduces the methods to determine anti burst ability and reductibility of silica,analyses and discusses its determination results.Both of the properties depend on crystal grain size of silica that means its size smaller,its anti burst biality greater and its reductibility better.The production shows that smelting 75% FeSi in 12.5MVA electric furnace with about 87% anti burst ratio can achieve better technical and economic indexes.
