Ceramic Foam Filter
Silicon Carbide (SIC) Ceramic Foam Filter is 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.
SIC filter plays an important role in the traditional copper industry, electrical and electronic copper industry and continuous casting and rolling technology.
It can effectively remove oxidized inclusions and other non-metallic inclusions by blocking and capturing adsorption of molten copper or iron using three-dimensional structure.
The quality will be very stable and satisfying no matter gray iron, ductile iron, shaft body, cylinder block or complex large pieces, hardware parts after filtered by SIC filter.
Parameter
Silicon Carbide (SIC) Ceramic Foam Filter produced by our company adopts imported raw materials from Germany and advanced laser cutting technology, which can meet the requirements of manual modeling and mechanized production line with higher efficiency, and ensure the quality standard requirements of casting factory productization.
Excellent raw materials and advanced production technology ensure quite stable dimensional tolerance of our ceramic foam filters.
Due to the larger specific gravity of copper and alloys, including zinc alloys, greater thermal shock will be generated during casting. Therefore, in the process of copper casting, the size of the silicon carbide foam ceramic filter is generally strictly regulated.
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.
