Aluminum Ceramic Foam Filters

Aluminum Ceramic Foam Filters have an open cell structure and several interconnected cavities surrounded by a ceramic fiber network. The porous structure of the filter helps to filter molten metal. Pour the molten metal into the ceramic foam filter to remove the solids entrained in the molten metal.

Aluminum Ceramic Foam Filters

There are many reasons for aluminum pollution. On the one hand, aluminum is exposed to the atmosphere in the furnace during the melting process in the molten or semi-melted state. Easy to oxidize, react with water vapor to absorb hydrogen, and easily form various forms of non-metallic slag. (Such as lining fragments, chlorides and carbides in flux, etc.) and coarse intermetallic particles.

On the other hand, some scraps that make up the batch bring some non-aluminum impurities into the recycling process. Because the waste comes from process waste and waste from various processes in the factory, and waste outside the factory, the route is different, the composition is complex, and the quality is poor.

The above-mentioned impurities tend to produce bubbles and inclusions in the cast slab, which seriously affect the purity of the molten metal, thereby further deteriorating the processing performance, mechanical properties, corrosion resistance and appearance of the product.

The quality of Aluminum Ceramic Foam Filters is very important and has a great influence on the subsequent processing performance and the quality of the final product.Therefore, countries all over the world attach great importance to the purification of molten aluminum.

Ceramic foam filters require precise performance under extreme high temperatures and harsh conditions, and must meet the highest standards in terms of performance, durability and heat resistance. This is where the expertise and engineering expertise of technology bubble services stand out. As a recognized leader in engineering-based foam conversion, our products are used by some of the most well-known foundries around the world for casting aluminum.

Alumina Ceramic Foam Filter is applied to purge and filter solution of aluminium and aluminium alloys. White in color alumina foam filter is made from high purity alumina (AI2O3). It has excellent ability to resist high thermal shock while maintaining efficient removal of impurities with continuous and thorough filtration.
