Degassing Process Aluminum Indonesia Equipment
The liquid aluminum alloy purification treatment process is the main means to improve the comprehensive performance of aluminum alloy. In the purification treatment process, the purification gas and the solvent are mixed, and the method of purifying the aluminum melt by the rotation of the graphite rotor on the degassing device is the most advanced treatment method in the world.
The refining equipment works as
The rotating rotor breaks the nitrogen (or argon) blown into the aluminum melt into a large amount of dispersed bubbles and disperses it in the molten metal.
The bubbles in the melt rely on the partial pressure difference of the gas and the surface adsorption principle, absorb the hydrogen in the melt, adsorb the oxidized slag, and are taken out of the surface of the melt as the bubbles rise, so that the melt is purified.
Due to the small dispersion of the bubbles, it is uniformly mixed with the rotating melt, and then rotates in a spiral shape and slowly floats. The contact time with the melt is long, and the air flow generated by the continuous straight rise does not form, thereby removing harmful hydrogen in the aluminum melt, which is remarkable. Improve the purification effect.
The rotating rotor breaks the nitrogen (or argon) in the aluminum water into a large amount of diffuse bubbles and disperses them in the molten metal.
The bubble in the melt depends on the gas partial pressure difference and surface adsorption principle, absorbs the hydrogen in the melt, absorbs the oxidized slag, and is taken out of the surface of the melt as the bubble rises, so that the melt is purified.
Due to the small dispersion of the bubbles, it is uniformly mixed with the rotating melt, and then rotates in a spiral shape and slowly floats. When it comes into contact with the molten metal, it does not form a continuous airflow, which significantly improves the purification effect.
Both argon and nitrogen can be used as an inert gas to degas the aluminum liquid. The purity of the inert gas must be above 99.95%.
