Foam Ceramic Filter Dirut Inalum can effectively remove large heterogeneous impurities in molten aluminum, and can filter out small inclusions of a few microns that cannot be removed by traditional processes.
Since the hydrogen atoms and other harmful ions in the aluminum liquid are often adsorbed on the inclusions, and the inclusions can become the core of bubble formation, therefore, while filtering out the inclusions, these harmful elements and gases in the aluminum liquid can also be reduced. Content.
Foam Ceramic Filter Dirut Inalum filters out many small inclusions, thus reducing the effective crystal nuclei required for the solidification of the molten aluminum, which can promote the nucleation and growth of the molten aluminum under large supercooling conditions, the structure is refined, and the product performance can be improved. improve.
Generally, there are three ways to remove particles suspended in the melt
Settling-particles accumulate at the bottom of the melt.
Floating-Inclusions float up and gather on the surface of the melt.
Filtration-the separation of particles from the melt through porous media.
