Product Description
Ceramic foam filter has the advantages of high prorosity, low loss of thermal shock, high mechanical strength at normal and high temperature, large specific surface, good chemical stability and excellent filtering functions of screen, filtering residum collection and absorption especially for tiny impurity of 1~10um. The three-dimension structure can improve the cast quality in large scale by changing the molten metal from turbulence flow to lamellar flow, removing the gas and smoothing the casting. It is not only applied for molten metal filtering in high temperature, but gas treatment in high temperature, carrier of catalyzer, solid heat exchange and advanced filling for chemical industry.

In addition to use as an insulating material, ceramic filter foam is also commonly employed in filtration applications. When used in refining other materials, ceramic foam filters generally provide three modes of filtration. Upon contacting the inlet of the filter, particles larger than the pore size are backed up on the filter's surface because they are too large to pass through. This backed up material forms a layer, known as the cake layer, on the surface of the filter that in turn captures smaller particles. The finest particles can pass through the cake layer but are then captured within the pores of the filter.

Ceramic foam filter Classification:
*Alumina / Al2O3 Ceramic Foam Filter
It's mainly for filtration of aluminum and aluminum alloys in foundries, for molten metal filtering under temperature of 1200 degree.
*Zirconia / ZrO2 Ceramic Foam Filter
It's used for molten all types of steels like unalloyed, low alloyed, stainless and high-alloyed as well as Nickel and Cobalt-based super-alloys, for molten metal filtering under temperature of 1700 degree.
*Silicon Carbide /SiC Ceramic Foam Filter
It's mainly for filtration of cast iron (grey iron & ductile iron) and non-ferrous alloys, for molten metal filtering under temperature of 1500 degree.

Ceramic Foam Filter is a kind of effective molten metal filter. It has the following advantages:
*High porosity
*Low loss of thermal shock
*High mechanical strength at normal and high temperature
*Large specific surface
*Good chemical stability
*Excellent filtering functions of screen
*Excellent filtering residua collection and absorption

Functions:
*Decontaminate the melting metal liquid
*Simplified gating system
*Improve the metallurgical structure of the castings
*Reduce slag inclusions of the castings
*Improve the casting quality rate
*Reduce casting internal re-oxidation defects
*Reduce the surface defects after machining of the castings
