Foam Ceramic Filter for Aluminum Foundry, Alumina Filter

The foam ceramic filter for aluminum foundry is made of high-quality and high-purity alumina, made of a unique formula and advanced environmental protection technology, and has a uniform three-dimensional network structure.

Şu ceramic filter foundry has excellent properties such as high strength, stable texture, no slag, high temperature resistance, and strong thermal shock resistance. Suitable for purification and filtration of high temperature aluminum and aluminum alloy solutions. It can filter non-metallic slag and melt to the micron level, make the surface of castings smoother and reduce machining losses.

Foam Ceramic Filter for Aluminum Foundry

The quality of the aluminum melt is very important, it greatly affects the subsequent processing performance and the quality of the final product. Therefore, all countries in the world attach great importance to the purification of aluminum melt.

There are many reasons for aluminum pollution. On the one hand, during the melting process, aluminum is exposed to the atmosphere in the furnace in a molten or semi-molten state, which is easily oxidized, easily reacts with water vapor to absorb hydrogen, and easily forms various forms of non-metals slag. (Such as furnace lining debris, chloride, carbide, etc.) and coarse intermetallic compound particles in the flux.

Öte yandan, birleştirilmiş hammadde yığınındaki hurdanın bir kısmı, geri dönüşüm sürecinde alüminyum olmayan bazı safsızlıklar içermektedir. Atıklar, fabrikadaki çeşitli işlemlerden kaynaklanan proses atıkları ve tesis dışından gelen atıklardan oluştuğu için, kaynakları farklıdır, bileşimleri karmaşıktır ve kaliteleri düşüktür.
Bu safsızlıklar, levhada kabarcık ve kalıntıların oluşmasına yol açar; bu durum, erimiş metalin saflığını ciddi şekilde etkiler ve dolayısıyla ürünün işlenebilirliğini, mekanik özelliklerini, korozyon direncini ve görünüm kalitesini olumsuz yönde etkiler.

The foam ceramic filter for aluminum foundry enables the molten aluminum to fill the cavity more evenly. Molten metal has a higher tendency to turbulence during the casting process. After the turbulent flow passes through the three-dimensional pore structure, it is finally transformed into a very stable laminar flow, which fills the cavity.

The foam ceramic filter for aluminum foundry reduces the impact corrosion of the metal solution to the casting cavity, significantly reduces the rejection rate, reduces the production cost, and improves the labor productivity.

Alümina seramik köpük filtreler are widely used in aluminum casting workshops such as aluminum alloy casting rods, casting billets, aluminum foil, aluminum cans, and high-end aluminum profiles. The filtration rate of 98-20 micron impurity particles is 98.3%, which helps to obtain perfect aluminum products. Various specifications can be produced according to customer requirements, ranging from 20ppi to 60ppi, and the maximum size can reach 26 inches.
