电解铝冶炼可能会产生下述杂质:从氧化铝厂来的氧化铝含有Si,Fe和痕量的Ti,Ca,V和B等元素。从加工阳极的装碳配料中进一步积聚的痕量Ti,V,Ca,Si和Fe等元素。在炭素厂生产中带来的痕量Si,P,Fe和Mn——主要是来自阳极,也从铸铁环和钢爪构成的阳极棒总成上带来。这些杂质在960℃时
Aluminum smelting may produce the following impurities: Alumina from the alumina plant contains Si, Fe and traces of Ti, Ca, V and B and other elements. Trace elements such as Ti, V, Ca, Si and Fe are further accumulated from the process of loading the anode charge carbon. Trace amounts of Si, P, Fe and Mn in the production of the carbon plant - mainly from the anode - are also brought on the anode rod assembly consisting of cast iron rings and steel claws. These impurities at 960 ℃
