Features of graphite rotor products:
1. Suitable for purifying aluminum liquid in crucible furnaces, ladles, and stop boxes
2. The degassing rate is above 50%, which shortens operation time and reduces production costs.
3. The precision-rotary degassing machine is divided into movable and fixed types, which are suitable for different operating environments.
The working principle of graphite rotor is that the rotating rotor breaks down the nitrogen (or argon) gas blown into the aluminum melt into many dispersed bubbles, and disperses them in the molten metal. Bubbles in the melt absorb hydrogen from the melt, adsorb oxidizing slag, and are carried out of the surface of the melt by the principle of the difference in gas partial pressure and surface adsorption, thus purifying the melt. Due to the fine and dispersed bubbles, they mix evenly with the rotating melt and slowly rise in a spiral shape as they roll. They have a long contact time with the melt and do not form a continuous linear upward airflow, which significantly improves the purification effect.
