摘要
根据混联法生产氧化铝的特点，本文从节能降耗出发，提出用烧结法粗液向拜耳法补碱的新工艺．经过实验室和工业试验得出：烧结法系统去拜耳法补碱的粗液量为补碱后拜耳法浆液总量的1／10～2／10。该新工艺可减轻烧结法脱硅机负荷，节约汽耗，同时降低拜耳法种分精液αk，为砂状氧化铝的生产创造有利条件。
According to alumina characteristics produced by combination- process, this paper proceeds from economizing on energy ＆ cutting down the consumption and points out the new process - using the coarse liquor from sintering process to supplement caustic of Bayer process. It＇ s concluded from laboratory and industrial test： the amount of coarse liquor to Bayer process supplementing caustic in sintering system is 1/10- 2/10 amount of Bayer process after supplementing caustic. The new process can reduce the desilication load in sintering - process, save steam consumption, lower fresh liquor αk of seed precipitation by Bayer process, and create favourable conditions for sandy alumina production.
