SIC ceramic foam filter used for Iron copper and steel casting filtration

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, simply, SIC ceramic foam filter.

Because of high strength and resistance to high temperature impact force and chemical corrosion, use temperature 1530°C of SIC ceramic foam filter, it is mainly used for filtering and purifying nodular cast iron, gray cast iron, aluminum, copper and other alloy metal liquid.

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 can effectively remove oxidized inclusions and other non-metallic inclusions by blocking and capturing adsorption of molten copper or molten iron using three-dimensional structure.

No matter gray iron, ductile iron, shaft body, cylinder block or complex large pieces, hardware parts after filtering, the quality will be very stable and satisfactory results.

SIC Ceramic foam filter is also suitable for copper, bronze, brass and other copper alloys, reduce the turbulence of copper liquid and purify the molten copper liquid.

What is especially valuable is that the life of copper castings purified by filtration is significantly prolonged in high requirements or harsh environment such as Marine turbine and chemical parts, and it also has good effect on the cast copper parts with surface polishing requirements.

SIC Ceramic foam filters also play an important role in the traditional copper industry, electrical and electronic copper industry and continuous casting and rolling technology.

There is strict size requirements for SIC Ceramic foam filter in the copper casting process because of greater specific gravity of copper and its alloys including zinc alloys and producing greater thermal shock during pouring.
