Formula and preparation method of high-temperature molten metal ceramic filter tube
The invention relates to the technical field of molten metal aluminum smelting and filtering, in particular to a formula and a preparation method of a high-temperature molten metal aluminum filter tube. A high-temperature molten metal aluminum ceramic filter tube formula comprises a solid raw material and a liquid raw material, and the solid raw material comprises 82-92% of brown aluminum oxide, 4-12% of a pore forming agent and 3-8% of a binder; the liquid raw materials comprise 5-40% of a nano aluminum dihydrogen phosphate solution, 50-90% of water and 1-15% of a lubricant; wherein the weight ratio of the solid raw material to the liquid raw material is (5-20): 1. The preparation method comprises the following steps: firstly, preparing ceramic powder, and then forming, drying, sintering, carrying out surface treatment and the like. According to the formula and the preparation method of the ceramic filter tube, the ceramic filter tube which has the aperture of about 300 microns and the aperture ratio of about 50% and is used for filtering high-temperature molten metal can be produced, localization of the ceramic filter tube in the application field is achieved, and import is replaced.
本发明涉及金属铝液冶炼过滤技术领域，特别是一种高温金属铝液过滤管的配方及其制备方法。一种高温金属铝液陶瓷过滤管配方，包括固体原料和液体原料，其中固体原料的原料为：棕刚玉82‑92％，造孔剂4‑12％，粘结剂3‑8％；而液体原料为：纳米磷酸二氢铝溶液5‑40％，水50‑90％，润滑剂1‑15％；其中固体原料和液体原料的重量比为(5‑20)：1。在制备时，首先制备陶瓷粉料，再经成型、干燥、烧结、表面处理等工序制备而成。该种陶瓷过滤管的配方及制备方法，可以生产孔径为300μm左右且孔径率在50％左右的、用于过滤高温金属熔液的陶瓷过滤管，实现该应用领域内陶瓷过滤管的国产化，替代进口。
