User manual for foam ceramic filter
Efficient silicon carbide/alumina ceramic foam filter for Metal / casting
Product Introduction
The Bsic materials Ceramic foam filter are silicon carbide, zirconia, alumina.
It can resistant high temperature to about 1560 ° C. It apply to all copper alloys and cast iron foundry which can significantly improve the quality of cast iron parts and reduce the rates of scrap.It can also be used in continuous casting and rolling process and can be made into all standard sizes and different thicknesses.
Ceramic foam filter for water or molten copper has an excellent filtering effect, its three-dimensional structure can effectively capture and adsorp the non-metallic and oxide inclusions. Whether it is gray iron, ductile iron, or shaft, cylinder or large complex, precision metal parts can be folter effectively.
Features :
Resistance to high temperature,
Chemical corrosion resistance,
High strength,
Uniform porosity distribution,
Long service life
Environment,Biological compatibility
Air permeability
Application:
decontaminate the melting metal liquid,Simplified gating system
Improve the metallurgical structure of the castings,Reduce imparities of the castings
Improve casting quality rate,Reduce casting internal re-oxidation defects
Reduce the surface defects after machining of the castings
