Aluminium Foundry Foam Ceramic Filter can effectively remove large heterogeneous impurities in liquid aluminum, and can filter out small inclusions of several microns that cannot be removed by traditional processes.
Because hydrogen atoms and other harmful ions in liquid aluminum often adsorb on the inclusions, and the inclusions can form the core of bubbles, the content of these harmful elements and gases in liquid aluminum can be reduced when the inclusions are filtered out.
Aluminium Foundry Foam Ceramic Filter filters out many small inclusions, thus reducing the effective crystal nuclei required for the solidification of liquid aluminum, which can promote the core growth of liquid aluminum under large undercooling conditions, refine the structure, and improve the product performance.
There are generally three ways to remove particles suspended in a melt
- Sedimentation – Accumulation of particles at the bottom of the melt.
- Float up – Inclusions float up to the surface of the melt.
- Filtration – Separation of particles from the melt through a porous medium.
The alumina ceramic foam filter is installed on the CFF Filter Box to filter the liquid impurities of the aluminum alloy to cope with the high added value and high technical performance of the aluminum alloy in the precision casting production of transportation and transportation.
The quality of aluminum melt is very important, it strongly affects the performance of the next processing and the quality of the final product. Therefore, all countries in the world have great desires for the refining of aluminum melt.
Nowadays, there are many ways to remove these harmful substances and purify molten aluminum.
According to the different methods, these methods can be divided into two categories: in-furnace purification and continuous out-of-furnace treatment (that is, online treatment).
According to different functions, it can be divided into main degassing or slag removal. The use of ceramic foam filter plates can continuously filter molten aluminum. External continuous treatment, the main purification operation is slag removal.
The ceramic filter for casting has a certain strength mesh structure, which can withstand the pressure difference of the metal liquid surface and the impact of the metal flow, but it is fragile and fragile. Because this material has a precise structure, uniform quality, wide surface, and excellent filtering effect.
