Abstract
Combining with alumina production practice by the alkali - lime sintering process, referring to foreign study achievements, the author studied the law of the viscosity, baking process and sintering feature of the raw slurry in the laboratory conditions. The test results showed that the true calcium ratio change had no effect on the viscosity of the raw slurry at the same moisture, but when the raw slurry moisture was less than 38% , its moisture and temperature increasing had a large effect on its viscosity. The slurry baking temperature in the gas suspension baking oven should be higher than 6001. Sintering temperature, the time of sintering retaining temperature, the cluster particle size and the structure consistency of the sintered material were the key to ensure a high quality of the sintered material.关键词
