◆ It can effectively eliminate large inclusions in the liquid aluminum.
◆ Removes fine inclusions of several microns in size in the liquid aluminum, which cannot be helped by conventional processes. At the same time, due to the filter plate off the small inclusions, reducing the effective number of nuclei in the liquid aluminum, so that the liquid aluminum in the larger subcooling conditions, nucleation growth, solidification time is shortened, the organization has been refined.
◆ Reduce the hydrogen content in the liquid aluminum. Hydrogen atoms can be adsorbed on some oxidized inclusions, and oxidized inclusions can become the core of bubble growth, so filtering out the inclusions also removes the gas on them.
◆ By adsorption, the content of harmful elements (Na K) in the liquid aluminum can be removed.
