High-stability low-cost preparation process of artificially synthesized mullite
The invention discloses a high-stability and low-cost preparation process of artificially synthesized mullite, and belongs to the technical field of mullites.The high-stability and low-cost preparation process of the artificially synthesized mullite comprises the following steps that 1, raw materials including a raw material A, a raw material B and a raw material C are prepared in advance, and all the raw materials are preliminarily crushed, screened and air-dried; step 2, proportioning and mixing the ferric oxide and the aluminum elementary substance in the raw material A, adjusting the proportion of aluminum oxide in the high bauxite and the kaolin in the raw material B, and drying and crushing. According to the present invention, by combining the aluminothermic reaction generated by the aluminum elementary substance and the iron oxide, the preliminary hot melting of a variety of raw materials can be achieved, and in the subsequent furnace kiln sintering process, the heating energy consumption ratio is saved, the mullite production energy consumption ratio can be reduced, the generation of a large amount of waste gas is not generated, and the actual environmental protection performance is high; the proportion of aluminum oxide is matched by utilizing multiple raw materials.
本发明公开了一种人工合成莫来石高稳定性低成本制备工艺，属于莫来石技术领域，该人工合成莫来石高稳定性低成本制备工艺，包括以下步骤：步骤一、预先准备原料，其中包括A原料、B原料与C原料，对所有的原料都进行初步的破碎、筛选和晾干，步骤二、将A原料中的三氧化二铁和铝单质进行配比与混合，将B原料含有的高铝矾土与高岭土，进行氧化铝占比调整，烘干粉碎。在结合铝单质和氧化铁产生的铝热反应，可以实现对多种原料进行初步的热熔，在后续的炉窑的烧结过程中，节约了加热的能耗比，即可降低生产莫来石的生产能耗比，且不会产生大量的废气，实际的环保性能也较高，利用多种原料配比氧化铝的占比。
