引言用霍尔—埃鲁特法每生产一磅铝需要近1/2磅的碳。这种碳必须含杂质最少,以免影响铝的质量。因此,对生产阳极的原料有严格的纯度要求。煅烧石油焦几乎是做阳极骨料的
Introduction Nearly ½-pound carbon is required for every pound of aluminum produced by the Hall-Elute method. This carbon must contain the least amount of impurities, so as not to affect the quality of aluminum. Therefore, the production of anode raw materials have strict purity requirements. Calcined petroleum coke is almost the anode aggregate
