SiC Ceramic Foam Filter 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.
SiC Ceramic Foam filters 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.
Silicon Carbide Ceramic Foam Filters 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. Apply to improve the quality of ductile, grey, and malleable iron casting, and help to slow the turbulence of the pouring gate. With excellent thermal shock resistance and high temperature strength, It can withstand the extreme environment in the process of iron casting. SiC Ceramic Foam Filters (CFS) is available in all standard dimensions and different thickness. The most common porosities are PPI 10, 20, 30 and 40; Higher porosities are available upon request. Custom-made cut-to-size filters are also possible.
SiC Ceramic foam filters help to enhanced quality of castings and reduce cost.
*Reduce defective rate of castings.
*Improve mechanical properties of castings.
*Reduced costs of finishing operations.
*Simplify pouring systems and increase utilization ratio of mold.
Selection
*Pore size is based on casting material and casting weight, regularly 10ppi for ductile, 20ppi for grey iron. 15ppi, 20ppi and 30ppi for other non-ferrous alloy.
*Filter size is decided by the sculpt, fusion and the characteristic of ceramic foam filter.
*7", 9", 12", 15", 17", 20", and 23", with porosities from PPI 10 to PPI 60(PPI ie pores per inch). Other special sizes could be produced on request.
