Ceramic Foam Filter

The ceramic foam filter has the advantages of high porosity, lowloss of thermal shock, high mechanical strength at normal and hightemperatures, large specific surface, good chemical stability, and is resistantto high temperature, chemical corrosion, and the scour of molten metal. Itcomes with excellent filtering functions and can effectively collect residuumand absorb especially tiny impurities of 1~10m. Due to these advantages, the honeycomb ceramic foam filteris used to filter and purify the liquid metal in metallurgy casting.

With its three-dimensional structure, the ceramic foam filter cangreatly improve casting quality as it can change the molten metal fromturbulence flow to lamellar flow, remove the gas and smooth the casting. Whenturbulent liquid metal is running through the cell holes of a ceramic foamfilter, it forms into a uniform and clean stream getting into the model evenly.The impurities of particles the size of micrometer and trapped air bubbles canbe removed effectively. This can prevent the founding model from eroding andthe scrap rate can be decreased. The ceramic foam filter can be madein different holes and porosity upon to use\'s demands.

In addition to molten metal filtering, the honeycomb ceramic foam filter can beused in gas treatment at high temperature environments, solid heat exchange andcatalyst carrier industry, and can be used as advanced filling for the chemicalindustry, etc.

The alumina ceramic foam filter can be made by specific procedures and havepeculiar bone-frame holes just like the shape of foam (called three-dimensionalconnected channel) and myriad eyelets which can only be seen when magnifiedunder a microscope. Compared with its counterparts, our ceramic foam filters have many advantages as state below:

1. Stable chemical composition
2. Excellent strength
3. Resistant to high temperature
4. The turbulent flow of metal is calmed down
5. Superior dimensional tolerances: +0/-2.5

Suggestions for Using theHoneycomb Ceramic Foam Filter
A. Themelting point of metals must be controlled properly, as an extreme hightemperature may destroy the filters function.
B. Choose a filter with a suitable pore size for different casting materials.
