Round Sic Ceramic Foam Filter for Molten Metal Casting

Silicon Carbide Ceramic Foam Filter are 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. 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. It can effectively remove inclusions, reduce trapped gas from liquid metal and provide laminar flow when applied as filter in gating system. We can offer various shapes, such as square, round and custom geometric shapes, Sizes from 10mm up to 600mm, and thicknesses from 10-50mm. The most common porosities are 10ppi, 20ppi, 30ppi, 40ppi, 50ppi, 60ppi. We also can be customized as per client's requirements. SiC ceramic foam filter work at 1500 degree centigrade, apply for iron, copper and copper alloy foundry.

The size are available in square, round and custom geometric shapes; Sizes ranging from 10mm up to 600mm, and thicknesses from 10-50mm. The most common porosities are 10ppi, 15ppi, 20ppi, 25ppi. Higher porosities are available upon request. Custom-made cut-to-size filters are also possible.
