10-30PPI Zirconia Ceramic Foam Filter for Casting
10-30PPI Zirconia Ceramic Foam Filter for Casting
Short Description:
Zirconia foam ceramic filter is made of high-quality and high-purity zirconia, using unique formula and advanced environmental protection technology. It has a uniform three-dimensional network structure, high strength, stable texture, no slag dropping, high temperature resistance, and thermal shock resistance ect excellent performance. Suitable for purification and filtration of stainless steel, carbon steel, copper castings and other high temperature alloy solutions below 1700C. Can filter non-metal slag inclusions and slags as small as micrometers, making the surface of steel castings smoother and reducing machining losses; the filter can make the molten steel fill the cavity more uniformly, and the molten metal has a higher turbulence during pouring tendency, the turbulent flowing through the three-dimensional pore structure is finally converted into a very stable laminar flow. Laminar flow fills the cavity better, which reduces the impact corrosion of the metal solution on the casting cavity, and significantly reduces the reject rate, reduces production costs, and improves labor productivity.
Zirconia Ceramic Foam Filter is a phosphate-free, high melting 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 zirconia 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.

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.

1.Efficiently filter metal particles impurities such as slag and refractory fragments to the micron level to reduce the loss of tools during machining of castings
2.The molten metal filling is stable and the structure of the casting is uniform, thereby improving the mechanical properties such as surface hardness, tensile strength and fatigue resistance of the casting
3.The three-dimensional mesh structure has a good rectification effect on metal turbulence, and has a good control effect on non-metallic inclusions and secondary oxidation caused by turbulent erosion of the cavity.
4.Simplified gating system and improved cavity utilization
5.The surface of the casting is clean, reducing the machining allowance, shortening the cleaning time, and improving the delivery efficiency
Widely used to filter various steel castings and large cast iron castings, high temperature master alloys and aviation castings, magnetic materials, continuous casting of copper-magnesium alloys and low-pressure casting of non-ferrous metal alloys
