A graphite rotor is a part of the aluminum alloy smelting equipment, specifically designed to facilitate the degassing and fluxing operations in the smelting process. It consists of a rotor pole and a nozzle, and its high-temperature resistance and chemical properties make it suitable for withstanding the harsh conditions of aluminum alloy smelting.
The graphite rotor manufactured by FRANLI generally has a default density of 1.7g/cm3. After anti-oxidation treatment, the density of the graphite rotor can reach 1.75-1.78g/cm3, which ensures the use and safety of the product. Users can adjust the density according to their requirements. If required, just provide the corresponding drawings.
Functionality and Applications of Graphite Rotors
Graphite rotors are utilized in a range of degassing and fluxing operations during aluminum and aluminum alloy smelting. They enable more efficient kinetic mixing of metal and help remove impurities such as hydrogen from the molten metal, ultimately contributing to producing high-quality aluminum and its alloys.
Users can input argon or nitrogen into the aluminum liquid at 750°C, and the rotation speed can be as high as 400r/min. By strongly stirring the aluminum liquid, the aluminum liquid can better melt into the argon or nitrogen and disperse many small bubbles. In liquid metal, the graphite rotor is also conducive to the diffusion of hydrogen in the aluminum melt, so that the bubbles in the melt contact through the gas partial pressure and surface adsorption principles, absorbing the oxide slag in the melt, and rise as the bubbles rise And be brought out of the melt surface to purify the melt.
Advantages of Graphite Rotors
The use of graphite rotors offers several advantages in the aluminum smelting process, including improved degassing efficiency, enhanced metal quality, and increased operational efficiency. Their high-temperature resistance and ability to withstand harsh chemical environments make them indispensable for ensuring the final aluminum’s quality and its alloys’ quality and purity：
1. The rotor does not contain any impurities and will not be contaminated during use.
2. The graphite rotor has the characteristics of high-temperature resistance and anti-oxidation.
3. Excellent self-lubricating performance and chemical corrosion resistance.
4. The graphite rotor has extremely high stability, such as high thermal conductivity and good thermal stability.
5. It has high mechanical strength and impact resistance.
