Molten Aluminum Graphite Rotor

Molten aluminum graphite rotor working principle is to break the inert gas into micron-sized bubbles and evenly disperse them into the aluminum liquid through high-speed rotation. The gas is injected through the graphite rotor, and the centrifugal force of the blades forms a fine bubble flow, thereby forming impurities floating above the aluminum liquid. The graphite rotor forms turbulence during rapid rotation, which accelerates the gas-liquid mass transfer process and promotes the homogenization of the melt composition.

The graphite rotor has strong high temperature resistance and does not react with the aluminum liquid. It can still maintain stable performance in continuous operation. In the process of molten aluminum, the graphite rotor plays a role of efficient degassing and purifies impurities, making the temperature and composition more evenly distributed under strong stirring. Compared with the traditional solvent method, the use of graphite rotor helps to reduce pollution emissions.

It is well known that graphite rotors are selected for their excellent performance, as follows:
1. High temperature strength
2. Self-lubricating properties reduce rotation resistance
3. Anti-aluminum liquid wettability
4. High thermal conductivity, etc.
