Foam ceramic filter has a three-dimensional pore structure, which purifies molten metal through filtration and adsorption, improves the surface and internal quality of castings. Because of its high porosity, large specific surface area, thermal shock resistance, high-temperature resistance, chemical corrosion resistance, and good mechanical strength and filtration and adsorption performance, it is widely used in the melting of non-ferrous metals such as cast iron, alloy steel, carbon steel, copper and aluminum. The different types of metal liquid to be filtered can be divided into silicon carbide, zirconium, corundum, and mullite. The product specifications and dimensions can be customized.
