煤矸石综合利用的新途径——电热法制取铝硅铁合金

A NEW WAY OF COMPREHENSIVE UTILIZATION OF GANGUE

本文在分析煤矸石及其粉煤灰综合利用现状的基础上指出,以其为原料冶炼铝硅铁合金不但可以充分利用其中的可燃物质和金属元素,而且还具有原料活性强,容易还原,来源广泛,价格低廉的优点。此工艺不但有重要的社会效益、环境效益和经济效益。而且还开辟了一种资源综合利用的新途径。

The current utilization of gangue and fine coal ash is reviewed.Gangue and fine coal ash are more active,easily reduced and obtained,and cheaper material to melting Al-Si-Fe Alloys.This new utilization of the wastes has a great advantage to society and environ- ment as well as economic benefit.
