| Abstract: | Baked calciam lime had huge effection on the circulation efficiency,digestion and evaporation sequences of the alumina production as the anti-causticization of the calcium lime in the alumina production.This paper checked the heat balance of pyrologic status of baked calcium lime,analyzed the defect of lime,baking from pyrology.Proposed the suggestion of improving bake quality of the lime to elimiate the harm of the production by pyrologic calculating and realize the purpose of de-bottlenecking expansion & efficiency in the production. |
