摘要
生产砂状氧化铝是关系到我国铝工业持续发展的一条技术路线。本文先从炼铁高炉推行“精料”方针谈起 ,论证了铝电解要求砂状氧化铝作原料、净化电解废气也需要砂状氧化铝以及氧化铝厂的工艺技术改革 ,并联系到巴西ALUMAR铝业公司采用 45
In this paper, a technical line for production of sandy alumina which is concernd with development of Chinese aluminum industry is put forward. From the policy of feeding “fine materials' to a blast furnace, the demand of both aluminum electrolyting and purification of electrolytic gas for sandy alumina is proved. The reformation of processing technology of alumina plant is discussed. The information about which Cyclone Fine Screen (CFS) 450 is applied for improvement of alumina quality by ALUMAR Corporation in Brasil is introduced.
