Alumina ceramic foam filters have the advantages with stable chemical property,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. |
A poem begins as a lump in the throat, a sense of wrong, a homesickness, a lovesickness. It finds the thought and the thought finds the words.
Robert Frost (1875-1963) American Poet.
