烧结法硅渣直接烧结回收氧化铝和碱工业试验

Commercial test of direct recovery of alumina and soda in Sintering process

论述了烧结法硅渣直接烧结回收氧化铝和碱实验方案、工艺流程、技术条件及技术改造,该流程生产运行稳定,达到了设计指标。同比熟料窑等传统热工设备具有热效率高、表面散热低的技术优势,是一项技术水平高、工艺独特的科技成果和生产应用,值得推广。

The paper presents the test plan, flow sheet, technical conditions and retrofit of direct recovery of alumina and soda in Sintering process, which is stable and obtains design indexes. Comparing with conventional equipment such as sinter kiln, it has the advantages of higher heat efficiency and lower surface heat dissipation, being a unique and advanced process technology.
