Raw material treatment process of castable

The invention relates to the technical field of castable, in particular to a raw material treatment process of castable, which comprises the following steps: after bauxite enters a field, spraying water to the bauxite by using a mixed solution prepared by mixing sodium bicarbonate and water, and then stewing and digesting the bauxite for at least six months; the mixed solution reacts with calcium oxide in the bauxite and the generated calcium hydroxide to generate calcium carbonate, the bauxite is sieved to remove the calcium carbonate therein after being covered and digested, and then the sieved bauxite is dried to obtain the raw material meeting the requirements, so that the aim of removing the impurities of the raw material is fulfilled. 本发明涉及浇注料技术领域，具体涉及一种浇注料的原材料处理工艺，在铝矾土进场后，利用碳酸氢钠和水混合制成的混合溶液对铝矾土淋水净化，然后将铝矾土闷放消化至少六个月，混合溶液与铝矾土中的氧化钙以及生成的氢氧化钙反应，生成碳酸钙，铝矾土闷放消化后，过筛，去除其中的碳酸钙，然后将过筛后的铝矾土烘干即得到满足要求的原材料，实现了去除原料杂质的目的。
