Porous Silicon Carbide foundry foam ceramic filter
Silicon Carbide foundry foam ceramic filter for filtration of cast iron and non-ferrous alloys
Silicon Carbide foundry foam ceramic filter mainly for filtration of cast iron and non-ferrous alloys. With their excellent resistance to attack and corrosion from molten iron liquid, they 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 Filters is available in all standard dimensions and different thickness. The most common porosities are PPI 10, 20 and 30; higher porosities are available upon request. Custom-made cut-to-size filters are also possible.
Advantage:
Filter the surdries in the castings, reduce the casting splracles, reduce the veins flowing when pouring the casting,reduce surface defects, obviously to improve the final-product rate.
Reduce castings manufacturing duration and the sword and tool damages, improve casting surface manufacturing quality
Strengthen castings anti-pressure and airproof features, strengthen elongate anti-resistance intensity, to improve surface glabrousness
Predigest casting system designing requirement,reduce the length of horizontal casting channel, improve castings technology output rate.
