Ceramic Foam Filter
Alumina ceramic foam filters are mainly used in the purification process production of non-ferrous alloys such as aluminum and aluminum alloys.
Mainly used for the filtration of molten aluminium and alloys in foundries and cast houses.
With excellent resistance to attack and corrosion from molten aluminum, the filter can effectively remove inclusions, reduce trapped gas and provide laminar flow. 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 the bottom-line profit.
Parameter
Alumina foam ceramic is a kind of foam material made from high purity alumina. The foam ceramics have the characteristics of uniform porosity, high temperature resistance, heat shock resistance, wear resistance and chemical stability.
Widely used in casting processing, water treatment, chemical industry, environmental protection and other industries. It is the ideal liquid aluminum filter, Catalyst support and good sound insulation, thermal insulation material.
They can also be used as gas-solid, liquid-solid separation medium, catalyst substrate, ceramic burner, sound absorption, environmental protection, and other fields.
Product shapes, sizes, and voids PPI can be designed and manufactured on request.

Alumina ceramic foam filters are mainly used for the filtration of molten aluminium and alloys in foundries and cast houses.
There are many reasons for aluminum pollution:
On the one hand, in the smelting process, aluminum is exposed to the furnace atmosphere in a molten or semi-molten state, easy to oxidize, easy to react with water vapor and absorb hydrogen, easy to form various forms of non-metallic slag (such as furnace lining debris, chloride, carbide in flux, etc.) and coarse metal intercompound particles and so on.
On the other hand, part of the waste that makes up the charge brings some non-aluminum impurities into circulation.
Because the waste is coming from the process waste and scrap during each process in factory and the waste outside the factory, so, the composition is complex due to different way as well as the quality is poor. These impurities often make the billet produce bubbles and inclusions, which seriously affect the purity of the metal melt, thus further affect the processing properties, mechanical properties, corrosion resistance and the appearance quality of the product.
Alumina foam ceramic filter can effectively remove all kinds of inclusions with fineness up to micron level in aluminum liquid, make aluminum liquid into a steady laminar flow, which is conducive to filling.
It has a unique mullite-corundum structure, good mechanical strength and chemical stability, excellent resistance to aluminum liquid erosion performance.
It can obtain stable filtration effect by strict control of hole size and through hole rate.
