Product Description

Description and Working Principle of Aluminum degassing
Aluminum degassing is a process used in the manufacturing of aluminum alloy castings. During the aluminum and aluminum alloy smelting process, hydrogen generated by chemical reaction with water vapor diffuses into the molten aluminum, causing internal structural defects in aluminum products. To avoid this defect, most aluminum plants use dissolved gas flotation to purify the molten aluminum by injecting inert gases such as nitrogen and argon into the molten aluminum. As inert gas diffuses and rises, hydrogen is brought to the surface of the molten aluminum.

 

Description of Aluminum degassing graphite rotor

Aluminum degassing graphite rotor is a part of aluminum alloy smelting equipment, which can help remove hydrogen and oxidation residues.
The aluminum degassing graphite rotor forms bubbles on the contact surface between the molten aluminum and inert gas, and increases the gas-liquid contact area, thereby accelerating the diffusion and removal of hydrogen. At the same time, the aluminum degassing graphite rotor can also adsorb and remove oxidization residues in the molten aluminum, and improve the quality and performance of the aluminum alloy.
 

High-Performance Graphite Rotors & Impellers for Aluminum Melt Processing
Our premium-grade graphite rotors and impellers are engineered for superior performance in aluminum melt degassing and purification systems. Designed to withstand extreme operational conditions, these components deliver unmatched durability and efficiency in molten aluminum treatment applications.
 

Key Features

• High mechanical strength
• Low coefficient of thermal expansion
• Good thermal shock resistance.
• Good chemical stability, and excellent resistant to acids, bases and organic solvents.
• No wettability to molten aluminum, and do not chemically react with aluminum.
• Advanced Oxidation Protection: Special anti-oxidation treatment extends service life.
• Precision Engineering: CNC-machined to ±0.01mm tolerance for perfect balance and vibration-free operation

 Special Treatment

• Impregnation anti-oxidation treatment: To extend the service life of the aluminum degassing graphite rotor shaft, we fill the pores of the graphite material with exclusive technology and nano-antioxidants, processed the graphite rotor shaft through vacuum impregnation, pressurization, and curing treatment to improve its anti-oxidation performance.
• Coating anti-oxidation treatment:Except for the threads, exclusive coating materials are applied to the impregnated anti-oxidation graphite rotor and shaft. The coating material does not penetrate into the aluminum, but adheres well to the graphite material. Due to its heat resistance, anti-oxidation, corrosion resistance, and abrasion resistance, the service life of the aluminum degassing graphite rotor and shaft is greatly extended after further coating treatment.
