一、前言采用混联法流程生产氧化铝,应尽可能减少其中的烧结法产品比例,这是降低热耗、减少氧化铝产品加工费及投资的极为有效的措施。在氧化铝生产工艺上,通过降低拜耳法赤泥铝硅比,采用低铝硅比生料烧成、就可以减少混联法系统中烧结法产品比例。目前,国内混 First, the preamble Adopting the hybrid process to produce alumina, the proportion of sintered products should be reduced as much as possible. This is an extremely effective measure to reduce heat consumption, reduce the processing fees and investment in alumina products. In the alumina production process, by reducing the Bayer process red mud ratio of aluminum and silicon, the ratio of low-alumina silicon raw material firing, you can reduce the proportion of sintering method in the mixed system. At present, the domestic mix
