Ceramicfoam filter is a kind of effective molten metal filter. It’s three-dimensionalconnected mesh skeleton structure and high porosity makes it has manyadvantages,large surface area of slags collection,largeinner surface area of filtering,Small flow resistance,goodfiltering effect,etc.
Functions of ceramic foam filter
decontaminatethe melting metal liquid,Simplified gating system,Improve casting qualityrate,Reduce casting internal re-oxidation defects.Reduce the surface defectsafter machining of the castings
