Recycled aluminum alloy contains more metal and non-metal impurities and must be further refined. Impurities refining methods include ceramic foam filter filtration, gas refining, flux refining, vacuum refining, and oxidation refining. The first four methods are used to remove non-metal impurities, and the latter method is used to remove metal impurities. When the regenerated aluminum […]
The requirements for the purity of the melt vary slightly with different alloy types and uses. Generally, the hydrogen content is required to be less than 0.15cm^3/100gAl, and the mass fraction of sodium is generally required to be controlled below 5/10^6. In order to obtain a pure aluminum alloy melt, it is necessary to add […]
