Product Description

Refractory Ceramic filters for casting
Ceramic Foam Filter

Ceramic foam filters have a foam-like porous structure. They are made of refractory materials that are resistant to molten metal erosion.The filter can effectively remove non-metallic inclusions including slag and dross from the molten metal stream. Additionally, they aid in reducing turbulence in the gating system. There are three ceramic foam filters, alumina, silicon carbide (SiC) and zirconia foam filters.They can be supplied in round, square, rectangular or other customized shapes with different pore sizes and porosities.
ceramic foam filter's outstanding thermal shock resistance and high strength properties were developed for superior performance in extreme iron foundry applications.
• Sand casting
• Investment casting
• Shell casting
• Low-pressure die casting
• Permanent mould casting

Extruded Ceramic Filter
The extruded Honeycomb ceramic filter is a fine filter with straight pore structure.  It is mainly used in metallurgy and foundry industry to filter out impurities, reduce casting porosity, eliminate turbulence in the metal stream and improve casting quality. Compared with the foam filter, it is more cost-effective. The ceramic honeycomb filter has basic filtering capacity and high heat capacity, so it has been widely used in small size and small thickness gray cast iron castings.
