Zirconia Filtering Foam

Product Description

Zirconia Ceramic Foam Filter is a kind of material which is phosphate-free, high metling point, 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, the combination of physical properties and precise tolerance make it the best choice for molten steel, alloy steel, and stainless steel, etc.


Product Characteristics

1. Filter out the inclusions in the casting, reduce the gas in the casting, reduce the degree of turbulence during the flow filling of the metal, reduce the surface defects in the casting, and significantly reduce the rejection rate of the casting.

2. Improve the fluidity of molten metal, increase the filling ability and shrinkage ability of the casting, improve the surface finish of the casting, increase the compression seal of the casting, enhance the elongation and tensile strength, and improve the surface quality and mechanical properties of the casting.

3. It has very high temperature working strength, chemical stability, thermal shock resistance and resistance to metal liquid flow impact. High chemical stability makes it not affected by the acidity and alkalinity of the molten metal and does not change the chemical composition of the molten metal. There is no slag dropping or cracking in the work, which ensures the filtration quality of molten metal and the stability of chemical composition.

4. It has a large metal flow rate, and the flow rate is stable (different from the straight hole ceramic filter, the flow rate gradually decreases with the increase in the number of captured impurities). Its filtering effect is much higher than that of other filter elements.

5.It has very high dimensional accuracy and can be used in the production line for automatic filter placement.
