Aluminum Melt Ceramic Filter

Aluminum Melt Ceramic Filter

Aluminum Melt Ceramic Filter is a cost-effective filtration medium to reduce impurities and inclusions in the molten metal before casting and rolling. The quality of aluminum melt treatment will affect the product quality of ingot casting and rolling, and then affect the product quality of subsequent processing and materials. Therefore, the aluminum melt ceramic filter filtration technology is an important part of the production technology of aluminum processing materials.

Inclusions refer to some refractory foreign substances with high melting points in the aluminum melt. Inclusions are a common phenomenon in the production of aluminum castings. Inclusions can be divided into solid inclusions and liquid inclusions, and their particle size ranges from a few microns to a few millimeters.

If these inclusions are not removed cleanly, they will form large defects in the aluminum alloy. They often cause stress concentration and cause the casting to be scrapped. It not only affects the mechanical properties, cutting performance, and corrosion resistance of the casting, but also causes porosity in the casting.

Aluminum Melt Ceramic Filter is widely used in aluminum foundries and cast houses. It is also called alumina ceramic foam filter, the filter has a large and stable metal flow, even if the high content of inclusions in molten metals, ceramic foam filter will not be plugged. The high dimensional accuracy can be automatically placed in the production line.

Ceramic foam filter has excellent resistance to attack and corrosion from molten aluminum, can effectively remove inclusions, reduce trapped gas and provide laminar flow, and 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 bottom-line profit.

Ceramic foam filters for aluminum melt filtration are available in all common sizes: 7″, 9″, 12″, 15″, 17″, 20″, and 23″. AdTech offers the ceramic foam filter whole range of porosities from PPI 10 up to PPI 60 (PPI = pores per inch). Custom-made cut-to-size filters are also possible.
