Alumina has excellent strength and resistance to high-temperature impact and chemical corrosion. Therefore, it is suitable for casting of all aluminum alloys. The alumina ceramic foam filters can significantly improve the quality of cast aluminum parts and reduce the waste rate. Alumina ceramic foam filter can also be used in the continuous casting and rolling process and can be manufactured into all standard sizes and different thicknesses.
The ceramic foam filter can reduce the turbulence of molten aluminum and rectify and purify molten aluminum. The filtered and purified aluminum castings can significantly extend the service life of aviation, automobile parts, and other high-demand parts, and they also have good effects on aluminum and copper parts with surface polishing requirements. Foam ceramic filters also play an important role in the traditional aluminum industry, electrical aluminum industry and continuous casting and rolling processes. Because aluminum and alloys have a greater specific gravity and produce greater thermal shock during pouring, the alumina foam ceramic filter used in the aluminum casting process generally has strict regulations on the size.
The use of the filtration process is mainly based on the following considerations. On the one hand, the filtration makes the flow of the molten aluminum become orderly and relatively calm, and on the other hand, the solid slag in the molten metal is effectively removed, and the quality of the castings is rapidly improved.
The alumina foam ceramic filters effectively remove solid inclusions in the molten metal, so the aluminum alloy can be smoothly forged, aluminum foil manufacturing, extrusion processing, etc. to obtain perfect aluminum. The product has a coarse pore size of 10ppi to an extremely fine pore size of 70ppi. Choose the range, so there will always be a product standard that suits your requirements. Both ordinary size and special size required by customers can meet the requirements.
