Alumina ceramic foam filter is a new type of low density, high porosity, and with a three-dimensional network skeleton structure of ceramic foam filters. And widely used in the aluminum process industry for molten aluminum filtering, so as to improve aluminum quality. Alumina ceramic foam filter can effectively remove the non-metal solid mixture from aluminium and aluminium alloy fusant, 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, to improve the quality of aluminum alloy and other non-ferrous alloy castings, all of which contribute to reduce casting cost, its maximum service temperature of 1200° C.
Alumina ceramic foam filters have the advantages of high porosity, high mechanical strength, stable chemical property, strong corrosion-resistant, high adsorption rate, excellent filtering functions and thermal shock
resistance. It is mainly used for purification process of aluminum, aluminum alloy, and other nonferrous alloy production, can
also be used as gas-solid, liquid-solid separation medium, catalyst carrier, burner and sound-absorbing and environmental
proper and tight position of the filter within the filter box. There are different types of gasket available, e.g. ceramic fiber gasket etc., also can provide alumina ceramic foam filter without gasket. These types of filters have been favored by customers from Europe and the United States for years.
