Aluminum Foundry Filters use automatic extrusion equipment to evenly distribute the slurry in the foam skeleton.
With the development of science and technology, people’s requirements for aluminum and its alloy materials are getting higher and higher. The traditional refining and degassing process cannot remove the small non-metallic inclusions in the aluminum melt. Therefore, many people have conducted research on purification methods. According to different mechanisms and forms, they can be divided into adsorption purification, physical purification, and filtration purification.
Aluminum Foundry Filters filtration and purification are to allow the liquid metal to flow through the medium, capture impurities through a certain mechanism, and purify the metal. Foam ceramic filters are used to improve the production efficiency of cast aluminum and are widely used in the production of semi-continuous casting and die casting.
There are many classification methods for ceramic cast filters. According to the pore relationship, it can be divided into two types: closed pores and open pores.
- According to the pore size, it can generally be divided into three categories: microporous ceramics (pore diameter <20 nm), mesoporous ceramics (pore diameter 20 nm ~ 500 nm) and macroporous ceramics (pore diameter> 500 nm).
- According to the pore formation method and pore structure, it can be divided into porous ceramics, honeycomb ceramics, foam ceramics and so on.
- According to different materials, it can be divided into silicon carbide ceramic filter, alumina ceramic filter, zirconia ceramic filter and so on.
Advantages of AdTech Aluminum Foundry Filters
- Adopt the principle of adsorption to filter. The alumina ceramic foam filter can effectively remove the larger inclusions in the molten aluminum and effectively adsorb the micron-level fine inclusions. Under the same mesh size, it has a higher filtration accuracy.
- No slag drop, effectively reducing the pollution of molten aluminum.
- It has good thermal shock resistance and molten metal corrosion resistance.
- Automatic production line, three calibration procedures, accurate size, more suitable for filter box.
- Improve surface quality, product performance and microstructure.
