Product Details
Product Description :
Our company offers SiC filters in all common sizes starting from 1.5×1.5×0.5” up to 6x4x1.25” and 6x6x1.25” mm. Filters sized 6×4” and 6×6” are recommended to be used in thickness 1.25” instead of the common thickness of 7/8”. 1.25” thick filters have the advantage that the bending strength is significantly higher than that of 7/8” thick filters. Therefore the filters can also be used for larger castings or longer casting times. Custom tailored solutions ( e.g. conical shaped filters ) are available on request. The listed porosities below are used most widely: PPI 10: Grey and Spherical Iron PPI 20: Spherical Iron and casting with a very high demand on quality PPI 30: Malleable Iron and castings with an extremely high demand on quality.
Advantage:
Reduce gas and inclusions that are contained in the casting, reduce the turbulence level of molten metal when filling the mold, reduce surface defects in castings, and significantly reduce the rejection rate of casting
Application:
It is widely used in molten metal filtration to remove undesirable nonmetallic inclusions in the melt.
