Large size graphite rotor for degassing vehicles

The graphite rotor forms bubbles on the contact surface between the molten aluminum and an inert gas, increasing the gas-liquid contact area. This accelerates the diffusion and removal of hydrogen, a common impurity in molten metals. 

These rotors are made of high-purity, anti-oxidation graphite, which is known for its high strength, high temperature resistance, and resistance to corrosion by aluminum flow. The specifications of graphite rotors can range from Φ 70mm to 250mm.

In addition to degassing vehicles, graphite rotors are also used in large furnaces. They are self-lapping, flexible, very hard, self-lubricating, and resistant to wear. They can be lubricated by almost any fluid, making them versatile across different applications. 

1. In-furnace degassing: Graphite rotors are used in in-furnace degassing operations to remove impurities such as hydrogen from molten metals.

2. In-line degassing: They are also used in in-line degassing processes, where they facilitate the removal of impurities directly in the production line.

3. Flux injection: Graphite rotors are used in flux injection processes, where they help in the distribution of fluxing agents in molten metals.

4. Aluminum alloy smelting: Graphite rotors play a vital role in the degassing and fluxing operations of the aluminum alloy smelting process. They facilitate the removal of hydrogen and oxidation residues, which are produced during aluminum alloy smelting.

5. Automotive industry: In the automotive industry, graphite rotors are recognized for their exceptional heat dissipation capabilities, which contribute to improved braking performance, reduced wear and tear, and overall enhanced safety.

These applications leverage the unique properties of graphite, such as high-temperature resistance, oxidation resistance, and durability, making graphite rotors an essential component for the efficient and reliable degassing of metals.
