honeycomb ceramic foam filter for fitlering iron/steel/alumina water

honeycomb ceramic foam filter for fitlering iron/steel/alumina water
Product Detailed
ceramic foam filter 1.High porosity 2.Good thermal shock resistance 3.High mechanical strength 4.Stable chemical property

ceramic foam filter is resistant to high temperature, chemical corrosion, and the scour of molten metal. It has high strength, high porosity and large surface area and mainly used to filter and purify the liquid metal in metallurgy casting.

When turbulent liquid metal running through the cell holes of ceramic foam filter, it formed into a uniform and clean stream getting into the model evenly, the impurities of particles in size of micrometer and air bubbles trapped have been removed effectively, prevent the founding model from erode, and the scrap rate can be decreased. The ceramic foam filter can be made in different holes and porosity upon to use's demands.

Alumina ceramic foam filter can be made by specific procedures and have peculiar bone-frame holes just like the shape of foam(Called three-dimensional connected channel) and myriad eyelets which only been found in big times microscope. Compare to similar ones, our products have many advantages as below: --Stable chemical composition--Excellent strength--Resistant to high temperature--Calm down of the turbulent flow of metal nicely--big m2/m3--Superior dimensional tolerances: +0/-2.5

Suggestions: A. Control the melting point satisfactorily. Especially high temperature will destroy it's function. B. Suitable PPI for different casting materials. C. Use the maximum temperature as soon as possibly. D. The pouring highness don't exceed 20cm commonly, and metal liquid don't touch the filtration directly.

Routine size:(It can also be made according to your requirement)

178x178x50 mm or 7'' x7''x2''(20--50ppi)

229x229x50 mm or 9'' x9'' x2''(20--50ppi)

305x305x50 mm or 12'' x12'' x2''(20--50ppi)

381x381x50 mm or 15'' x15'' x2''(20--50ppi)

432x432x50 mm or 17'' x17'' x2''(20--50ppi)

508x508x50 mm or 20'' x20'' x2''(20--50ppi)

584x584x50 mm or 23'' x23'' x2''(20--50ppi)


Ceramic Foam Filter has the advantages of high porosity, 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 residuum collection and adsorption especially for tiny impurity of 1~10μm. The three-dimensional 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. Ceramic foam filter 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.

PXZT has developed three kinds of ceramic foam filters: Alumina foam filter, Silicon carbide foam filter, Zirconia foam filter.
