Graphite rotor for degassing of large furnaces
Graphite rotor is a crucial component used for degassing in large furnaces, particularly in the aluminum industry.
Product Info
Graphite rotors are widely used in the aluminum industry due to their high-temperature resistance, oxidation resistance, and durability. They contribute to the production of high-quality aluminum alloys by effectively removing impurities and ensuring the integrity of the final product.
During the smelting of aluminum alloys, impurities such as hydrogen and oxidation residues are produced. These impurities need to be removed to ensure the purity of the aluminum. The rotating rotor breaks the nitrogen (or argon) in the molten aluminum melt into a large number of dispersed bubbles, and disperses it into the molten metal
The operation of using a graphite rotor requires preheating before use to avoid oxidation and ensure the longevity of the rotor. Once preheated, the graphite rotor is immersed in the aluminum liquid in the degassing box, where it rotates at a specific speed to stir the aluminum liquid and facilitate the degassing process.
