摘　　要：通过正交试验与单因素试验考察了溶出时间、液固比、溶出温度及调整液中碳酸钠浓度等因素对烧结法熟料溶出过程的影响,并确定了影响因素的主次关系。结果表明,影响因素主次关系依次是温度、时间、液固比、碳酸钠浓度,在下述条件下,氧化铝溶出率达到91.26%:碳酸钠浓度20g/L、液固比5∶1、溶出时间30min、溶出温度80℃。The effects of temperature, time, ratio of liquid to solid（L/S）, and concentration of sodium car- bonate in correction liquor in clinker digestion process were investigated with orthogonal experiment and single factor experiment, and the four factors were determined based on influence momentum. The results show that the four factors in sequence from high to low are temperature, time, L/S, concentration of sodi- um carbonate. The leaching rate of alumina is 91.26% under the conditions including digestion tempera- ture of 80 ℃, dissolving time of 30 min, L/S of 5 ： 1, and concentration of sodium carbonate of 20 g/L.
