Silicon carbide ceramic foam filter is designed for filtering ductile iron, grey iron and non-ferrous alloys castings. With excellent resistance to attack and corrosion from molten iron liquid, it can effectively remove inclusions in molten metal, adsorbed impurity, reduce the molten metal in the gas and the harmful element content, decrease the reject rate, and improve the processing performance and mechanical properties of the casting.
Silicon carbide ceramic foam filter is designed for filtering impurities from molten iron & alloy, nodular cast iron castings, grey iron castings and malleable castings, bronze casting, etc.. Which have high porosity (80%-90%), high thermal shock resistance and large specific surface, compared with other traditional filters. It can effectively remove inclusions, reduce trapped gas from liquid metal and provide laminar flow when applied as filter in gating system.
