Ceramic foam filter is just developed as a new type molten metal filters to decrease casting flaw and also as a catalyst carrier for Air Treatment in recent years, play a vital role in the metal casting and air treatment, where they are used to filter out impurities in molten metal to improve the quality and performance of the end product or decompose organic pollutants into pollution-free water (H2O) and carbon dioxide (CO2) to meet high environmental requirements.

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. Product shapes, sizes, and voids PPI can be designed and manufactured on request.

7x7x2 12x12x2 inch Alumina ceramic foam filter plate with fiber paper are for our Venezuela client.

There are many reasons for aluminum liquid 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 plate 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.

The ceramic foam filter plate is surrounded by a sealing ceramic fiber liner, which facilitates the seal of the filter plate in the filter box to ensure that there is no metal liquid sideflow.
