Zirconia Ceramic Foam Filters are used for filtration of all types of steel like unalloyed, low alloyed, stainless and high-alloyed. Filters are recommended especially for high quality grades of alloys.
With their excellent resistance to attack and corrosion from molten steel liquid, they can effectively remove inclusions, reduce trapped gas from liquid metal and provide laminar flow, and then the filtered metal is significantly cleaner.
Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects. They are the best choice for filtering of determined for filtering of steel and steel alloys up to the temperature of 1700℃.

Filtration of Molten Steel and Alloy
Large Scale Iron Casting
SIC foam filter is insulating oxide ceramics that are thermally conductive. These ceramic foam filters are ideal for use in the casting process of ductile iron, layered iron, malleable iron and all other high and low alloy cast-iron types.
Effectively removes the solid inclusions in the Peirong metal, so the aluminum alloy can be smoothly forged, aluminum foil manufacturing extrusion processing and other processes to obtain high-quality products.
