据《中国环境报》报道(作者:郭薇)高铝粉煤灰和煤矸石工业化制备铝硅铁合金试验科技成果不久前在北京鉴定。由北京炎黄投资管理有限公司、北京航空航天大学完成的此项目在我国首次进行了利用粉煤灰和煤矸石等工业固体废料为原料,使用电热还原法直接制备铝硅铁合金的工业试验。?
According to “China Environment News” reported (Author: Guo Wei) alumina fly ash and coal gangue industrialization in Beijing not long ago identified the preparation of aluminum-silicon ferroalloy test scientific and technological achievements. The project completed by Beijing Yanhuang Investment Management Co., Ltd. and Beijing University of Aeronautics and Astronautics carried out for the first time in our country an industrial test for directly preparing aluminum-silicon-iron alloy by using electrothermal reduction method using industrial solid waste such as fly ash and coal gangue as raw materials. ?
