SIC Ceramic foam filters are suitable for the casting of all copper alloys and cast iron because of its high strength, resistance to high temperature impact force and chemical corrosion and operating temperature 1530°C.

Silicon carbide ceramic foam filter adopts German imported polyurethane foam sponge as the carrier, the slurry which mainly contains silicon carbide is extruded into the foam sponge, and then extrude slurry, the remaining slurry coated around the foam fiber is dring, roasting and sintering at high temperature, polyurethane is decomposed by heat, foam shaped ceramic products are left, namely, silicon carbide foam ceramic filter. 

SIC ceramic foam filter with foam sponge three-dimensional mesh interworking structure can make the metal liquid reflect the rectification, mechanical screening, filter cake, adsorption filtration mechanism to effectively improve the purity of metal liquid, reduce scrap rate, reduce machining losses so as to improve production efficiency and reduce production costs. 

SIC ceramic foam filter has the characteristics of high strength, good thermal stability, large specific surface area and high dimensional accuracy.

Mainly used for filtering and purifying nodular cast iron, gray cast iron, aluminum, copper and other alloy metal liquid filtration.
