The high temperature flue gas dust removal metal membrane filter cartridge is made from industrial high-purity metal powder, processed via sieving, cold isostatic pressing, and sintered in a high temperature and high vacuum environment, resulting in a powder-sintered structure. The cartridge features high strength, excellent deep filtration performance, good air permeability and separation effect, high temperature resistance, and shape stability. It is widely used in metallurgy, chemical, waste incineration, glass, ceramics, coal power plants, cement industry, steel plants, and glass kilns for high-temperature dust-laden gas purification and collection, ensuring long-term stable operation.
