Zirconia ceramic foam filter is made of high-purity, high-quality zirconia, with a unique formula and advanced environmental protection technology, which has a unique three-dimensional uniform pore structure, withstands temperatures up to about 1700°C. Zirconia ceramic foam filter can effectively remove inclusions, reduce trapped gas from liquid metal and provide laminar flow when applied as filter in gating system, and then the filtered metal is significantly cleaner. Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects, all of which contribute to bottom-line profit.
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.zirconia ceramic foam filter 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
