High Density Refractory Alumina Ceramic Foam Filter Casting Filtration

Alumina Ceramic Foam Filter is Al2O3, with refractoriness: 1400, high strength and good heat-resistance wallop, apply to purge and filter solution of Aluminium alloy and other nunferrous alloy. It is mainly used for filtration of aluminium and aluminium alloys in foundries and cast houses. With their excellent thermal shock resistance and corrosion resistance from molten aluminum, they can effectively eliminate inclusions, reduce trapped gas and provide laminar flow, and then the filtered metal is significantly cleaner.

The three-dimension structure can improve the cast quality in large scale by changing the molten metal from turbulence flow to lamellar flow, removing the gas and smoothing the casting. It is not only applied for molten metal filtering in high temperature, but gas treatment in high temperature, carrier of catalyzer, solid heat exchange and advanced filling for chemical industry.

Alumina Ceramic Foam Filters mainly for filtration of aluminum and aluminum alloys in foundries and cast houses. With their excellent resistance to attack and corrosion from molten aluminum, they can effectively remove inclusions, reduce trapped gas 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, all of which contribute to bottom-line profit. It is applied to improve the quality of aluminum alloy and other non-ferrous alloy casting, improve metallurgical structure enhance mechanical properties change turbulence into laminar flow.
