1. Introduction:
Foam Ceramic are 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. Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects, all of which contribute to bottom-line profit.
High porosity, Low loss of thermal shock, High mechanical strength at normal and high temperature, Large specific surface, Good chemical stability and Excellent filtering functions ofscreen, filtering residuum collection and adsorption especially for tiny impurity of 1~10μm. The three-dimensional structure can improve the cast quality in large scale by changing the molten metal from turbulence flow to lamellar flow, removing the gass and smoothing the casting. Ceramic foam filter 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.
