Preparation method of alumina refractory material
The invention relates to the technical field of alumina refractory materials, in particular to a preparation method of an alumina refractory material. The preparation method comprises the following steps: 1, screening bauxite and bauxite, removing impurities, and putting the bauxite and the bauxite into a preparation device; 2, grinding the bauxite and the bauxite through a preparation device to obtain powder; 3, mixing caustic soda and water into the powder to obtain basic slurry; 4, cleaning and precipitating the basic slurry, and then carrying out pressurized dissolution; the preparation device comprises a grinding barrel, a grinding rod rotationally connected to the upper end of the grinding barrel and a pipeline fixedly connected to the upper end of the grinding barrel, a plurality of nozzles are arranged at the lower end of the pipeline, and inclined hoppers are arranged at the left end and the right end of the grinding barrel; according to the present invention, the reaction can be performed by using the generated temperature when the bauxite and the bauxite are ground.
本发明涉及氧化铝耐火材料技术领域，更具体的说是一种氧化铝耐火材料制备方法；步骤一：将铝矾土与铝土矿石进行筛选，祛除杂质后投入到制备装置当中；步骤二：通过制备装置对铝矾土与铝土矿石进行研磨得到粉末；步骤三：将苛性钠和水混入到粉末当中得到基础泥浆；步骤四：将基础泥浆进行清洗并沉淀后加压溶出；所述的制备装置包括研磨桶，以及转动连接在研磨桶上端的研磨棒，以及固定连接在研磨桶上端的管道，管道下端设置有多个喷嘴，研磨桶的左右两端均设置有斜斗；能够在对铝矾土与铝土矿石进行研磨的时候利用所产生的温度来进行反应。
