金属学报

采用模式识别与回归相结合的方法总结碳酸化分解生产数据的规律,得到了描述氢氧化铝产品SiO_2含量的数学模型表明在溶液Al/Si不变的条件下,溶液中Al_2O_3浓度高时氢氧化铝产品合SiO_2低,这一规律经小型实验得到了验证。

金属学报(英文版)

The regularity of the carbonization process in alumina production has been summarized by the pattern recognition and regression.A mathematical model has been proposed to describe the factors affecting the silica content of aluminium hydroxide product.The high concentration of aluminate ions in solution will produce aluminium hydroxide with low content of SiO_2 under the condition of Al_2O_3/SiO_2 ratio kept unchanged.This was confirmed by certain scale experiments.
