Zro2 Molten Metal Filter for filtering gray and ductile iron, as a rule, are used for installation in foundry half-molds of the bottom in specially provided for this recess. Ceramic foam effectively cleans metal melts when casting into single sand molds, metal chill molds and with continuous methods of casting non-ferrous metals (for example, filtering copper wires). Silicon carbide-based foam-ceramic filters (PCF SiC) are the universal, most common and popular filtering material in foundry.
