摘　　要：抚顺页岩废渣是页岩炼油产生的无机矿物,由于富含硅铝元素,冶炼成的硅铝合金用途广泛,值得研究。采用页岩废渣作主要原料,掺配石油焦作还原剂、钠基或氨基亚硫酸盐型纸浆废液作粘合剂进行了电热还原冶炼试验。试验结果表明,以页岩渣制取的铝硅铁合金含铝约15%,含硅59%,含铁23%。从成分上看冶炼的产品纯度较高,实现了由页岩废渣转变为金属合金的可能性。合金中铝以铝硅铁合金相存在,而铁主要以硅铁相和铝硅铁相存在,其中也含有一定量的碳化硅。合金最多的是硅,硅在整个合金断面均有分布,而铝多与硅在一起,铁也是与硅以硅铁形式在一起,钒与钛共生。Fushun shale Slag is an inorganic mineral produced by shale refining. Due to the high silica aluminum-richelements, the application of silicon aluminum alloy smelting is well worth studying. In this paper, the electrothermalreduction and smelting test was carried out by using shale Slag as the main raw material, with petroleum coke reducingagent, sodium base or amino sulfite waste liquid. The results showed that the aluminum ferrosilicon alloy made fromshale slag contains about 15% of aluminum, 59% of silicon and 23% of iron.The product purity of the smelting is higher,and the possibility of conversion from shale Slag to metal alloy is realized. The aluminum alloy is present in aluminumalloy, and the iron is mainly in the phase of silicon iron and aluminum silicon, which also contains a certain amount ofsilicon carbide. The most alloys are silicon, which is distributed across the entire alloy section, while aluminum is morethan silicon. Iron is also with silicon in the form of silicon, and vanadium and titanium are symbiotic.
