Zirconia Ceramic Foam Filter
Zirconia Ceramic Foam Filter
Zirconia Ceramic Foam Filter is a phosphate-free, high metling point, It is characterized by high porosity and mechanochemical stability and excellent resistance to thermal shock and corrosion from molten steel, It can effectively remove inclusions, reduce trapped gas and provide laminar flow when molten zieconia foam filtrated, it is machined to tight dimensional tolerance during production, this combination of physical properties and precise tolerance make them first choice for molten steel,alloy steel, and stainless steel, etc. Pore Density: 10-60 PPI
Functions of ceramic foam filter
●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

Guide of Choosing Ceramic Foam Filter
It’s very important to choose and design filter model & filter seat correctly according to casting
types and pouring weight. The general principle is that the whole gating system should be a
system without pressure to ensure that the molten metal liquid filling mould smoothly. Ratio of the
sectional area will be the main point.
