用碱石灰烧结法生产氧化铝时,生料烧结是最关键的过程。熟料必须在化学成分、矿物成分和构造上都符合工艺要求,才能保证熟料溶出和赤泥分离洗涤过程顺利进行。熟料的质量取决于许多因素。原料的成分、粒度和混合均匀程度、加热和冷却时的温度制度、气氛都有着重要的影响。而原料组成上的差别,又是最 Soda lime sintering alumina production, raw material sintering is the most critical process. Clinker must meet the technical requirements in terms of chemical composition, mineral composition and structure, so as to ensure the clinker dissolution and red mud separation and washing process proceed smoothly. The quality of clinker depends on many factors. Raw material composition, particle size and uniformity of mixing, heating and cooling temperature system, the atmosphere has an important impact. The composition of raw materials, the difference is the most
