Description
Foam ceramic filters exhibit a unique three-dimensional pore structure designed to refine molten metal by means of filtration and adsorption, thereby enhancing both the surface and internal quality of castings. Thanks to their elevated porosity, expansive specific surface area, resistance to thermal shock, high-temperature endurance, chemical corrosion resilience, and robust mechanical strength, along with their remarkable filtration and adsorption capabilities, these filters find widespread application in the smelting processes of non-ferrous metals such as cast iron, alloy steel, carbon steel, copper, and aluminum. Based on the specific type of metal melt to be filtered, foam ceramic filters can be categorized as silicon carbide, zirconium, corundum, and mullite variants. Furthermore, the specifications and dimensions of the product can be tailored to meet individual requirements.
