摘要
在烧结法工业生产氧化铝工艺中，碳分原液中Al2O3。浓度一般不高于110g／l，并且单槽分解周期长，消耗动力大，传统的碳分工艺已经成为制约设备产能和影响氧化铝生产企业经济效益的最主要因素之一。本文对铝酸钠溶液成分机理的不同观点进行了分析对比，并从影响成分过程和产品质量主要因素的角度，分析了高浓度铝酸钠溶液碳分的可行性。
Abstract: It is known that the sodium aluminate solution desilicated was transported to carbonation precipitation in the sintering-Lime Process and Bayer-Sintering Combining Process . Nowadays the Al2O3 concentration in the sodium aluminate solution is generally not more than 110g/l in the in dustrial production ,and which has become one of the primary factors restricting the equipment productivity, In this paper, the feasibility to to realize the carbonization precipitation with high alumina concentration in sodium aluminate sofution was researched based on the analysis of the mechanismof car bonization precipitation and the main affect factors in the process and on the product.
