Foam ceramic filters plate is an economical and convenient way to remove molten aluminum inclusions. It is widely used in filtering molten aluminum. The foam ceramic filters plate can provide sizes from 7 inches to 26 inches, and the size of through holes ranges from 20ppi. Up to 60PPI, the periphery of the ceramic foam filter plate is lined with 8mm aluminum silicate, which is used as a seal between the contact part of the filter plate and the Filter Liner to ensure that there is no aluminum liquid bypass.
What Is A Ceramic Filter? What does it do?
1. It can effectively eradicate large inclusions in molten aluminum.
2. It can remove small inclusions of a few microns in size that are incapable of conventional processes in molten aluminum. At the same time, because the fine inclusions are filtered out, the effective number of crystal nuclei in the molten aluminum is reduced, so that the molten aluminum nucleates and grows under relatively large supercooling conditions, the solidification time is shortened, and the structure is refined.
3. Reduce the hydrogen content in molten aluminum. Hydrogen atoms can be adsorbed on some oxidized inclusions, and the oxidized inclusions become the core of bubble growth, so the inclusions are filtered out and the gas on them is also removed.
4. Through adsorption, the content of harmful elements (Na K) in molten aluminum can be removed.
The unique three-dimensional structure of the foam ceramic filter can reduce trapped gas and provide laminar flow, so that the molten metal becomes clean, and high-quality castings can be produced.
The ceramic foam filters plate is mainly used for filtering high temperature of molten metal. It can not only filter residues, but also adsorb especially small impurities 1 ~ 10 μm. It is also suitable for high temperature gas treatment, catalyst carrier substrate, and solid heat exchange, and chemical industry.
