Preparation method for low-carbon production of refined mullite corundum high-temperature material
The invention relates to a preparation method for low-carbon production of a refined mullite corundum high-temperature material in the field of high-temperature refractory materials. The method comprises the following steps: step 1, grading a bauxite raw material; step 2, burdening; step 3, dry fine grinding; step 4, carrying out partial wet-process fine grinding; step 5, mixing and blending in proportion; step 6, mechanical pressing molding; and step 7, firing a finished product. The process has the characteristics that dry fine grinding is adopted as a main material, a large amount of water is prevented from being brought in, the low production cost of the process is ensured, wet fine grinding slurry is adopted as an auxiliary material and used as a binding agent, meanwhile, less than 6% of water is brought into the slurry to wet a dry material, the forming performance is ensured, and meanwhile, due to the fact that wet fine grinding components are more uniform and are added as a substrate of a product, the forming performance is improved. In addition, for products with different purposes and with different requirements on uniformity, the process of mixing dry and wet materials can be finished by adjusting according to different proportions directly in the process of mixing the dry and wet materials; and the process adjustment is more flexible.
本发明涉及高温耐火材料领域的一种低碳生产精细化莫来石刚玉高温材料的制备方法，该方法包括以下步骤：步骤1：铝土矿原料分级；步骤2：配料；步骤3：干法细磨；步骤4：部分湿法细磨；步骤5：按比例混合调配；步骤6：机压成型；步骤7：烧制成品；本工艺的特点是以干法细磨为主，避免带入大量水份，保证过程生产成本低，以湿法细磨泥浆为辅，作为结合剂，同时泥浆中带入6％以下水分对干料进行润湿，保证成型性能，同时，因湿法细磨成份更均匀，作为产品的基质加入，更能保证成品的成份均匀性，另外，对不同用途的产品，对均匀性要求的不同，直接在干湿物料混合这一道工序中，按不同比例调整就能完成；工艺的调整更加灵活。
