Preparation method of 3D printing magnesium-aluminum molten metal filtering device
The invention relates to a preparation method of a 3D printing magnesium-aluminum molten metal filtering device. The method comprises the steps of: taking industrial alumina powder, sintered corundumpowder/fused corundum powder, fused magnesia powder and sintered magnesia powder as raw materials; by taking dextrin, methylene cellulose or resin as a binding agent, carrying out ball milling, suction filtration and mixing on the raw materials and the binding agent to prepare magnesium-aluminum printing pug for 3D printing equipment, preparing the biscuit of the molten metal filtering device by virtue of a 3D printing technology, and drying and sintering the biscuit to obtain the finished product of the molten metal filtering device. The prepared 3D printing magnesium-aluminum molten metal filtering device has the advantages that the pore diameter is artificially controllable, the pore size and distribution are uniform, and the filtering effect is good; and meanwhile, the biscuit is sintered at high temperature, the filtering device is high in normal-temperature strength and high in structural density, the main crystalline phase is spinel, and high temperature resistance and corrosionresistance are high.
本发明涉及一种3D打印镁铝质熔融金属过滤装置的制备方法，以工业氧化铝粉、烧结刚玉粉/电熔刚玉粉、电熔镁砂粉、烧结镁砂粉为原料，以糊精、亚甲基纤维素或树脂为结合剂，原料和结合剂经球磨、抽滤、混合制备供3D打印设备使用镁铝质打印泥料，通过3D打印技术制备熔融金属过滤装置素坯，素坯经干燥、烧成后获得熔融金属过滤装置成品。本发明制备的3D打印镁铝质熔融金属过滤装置具有孔径人为可控，孔径大小、分布均匀、过滤效果好；同时素坯通过高温烧成，过滤装置常温强度大，结构致密度高且主晶相为尖晶石，耐高温、耐侵蚀性强。
