Product Description Zirconia Ceramic Foam Filters To meet the demanding requirements of steel foundries, we recommends the zirconia filter.Our filters are formulated of a magnesia-stabilized zirconia, the perfect composition for filtering steel grades from carbon to stainless. There are many benefits to the steel foundry including fewer reoxidation and sub-surface defects and a higher casting yield. They are highly thermal-shock resistant, a must for the steel foundry. They are available in many standard and custom sizes, shapes, and pore sizes.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 ofstainless 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, andsignificantly reduces the reject rate, reduces production costs, and improves labor productivity.Chemical Composition for Zirconia Ceramic Foam FiltersAl2O3MgOSiO2ZrO2Fe2O3≤1.8%≥3.0%≤0.5%≥ 94.00%≤0.10% Advantages: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 tometal 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.
