Alumina Ceramic Foam Filter is just developed as a new type molten metal filter to decrease casting flaw in recent years. With its characteristics of light-weight, high mechanical strength, large specific surface areas, high porosity, excellent thermal shock resistance, erode resistance, high-performance, SIC Ceramic Foam filter is designed for filtering impurities from molten Iron & Alloy, nodular cast iron castings, grey iron castings and malleable castings, Bronze casting, etc.
With their excellent resistance to attack and corrosion from molten iron liquid, SIC Ceramic Foam filter 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, all of which contribute to bottom-line profit.
Applications:
*Sand casting
*Investment casting
*Shell casting
*Low-pressure die casting
*Permanent mould casting
*Holding and transfer systems
Features
*Alumina ceramic marterial with three-dimensional network structure through high-temperature sinterings
*High strength, erosion resistance, strong adsorption of impurities, can effectively remove tiny inclusions in molten aluminum
*Wide range of applications
Advantages:
*Easily installed
*Resistant to molten aluminium
*Non-wetting
*Excellent hot strength
*Dimensionally stable
*Suitable for both horizontal and vertical placement
