以煤替代木炭生产工业硅

PRODUCING METAL SILICON WITH COAL INSTEAD OF CHARCOAL

分析了各种烟煤的物化性能,得出优质烟煤完全可以代替木炭作还原剂用于工业硅生产,从而达到无木炭生产工业硅的高产低耗的目的。

Physical and Chemical properties of various smoke coal are analysed. It is pointed out that high- quality smoke coal can completely replace charcoal as reductant in producing metal silicon thus the targets of higher output and lower consumption have been achieved.
