Graphite Rotor for Cast Aluminum Degassing

Graphite Rotor for Cast Aluminum Degassing

A graphite rotor is a critical component used in the casting of aluminum for degassing processes. It is made of high-purity graphite material that offers excellent thermal resistance, corrosion resistance, and durability. The graphite rotor is designed to remove impurities such as hydrogen and other gases from molten aluminum through a process called degassing. This increases the quality of cast aluminum, resulting in higher performance and cost optimization. Graphite rotors are widely used in the aluminum manufacturing industry for their exceptional performance, efficiency, and cost-effectiveness. They come in different sizes and configurations, allowing them to be used in a range of different applications.

During aluminum and aluminum alloys smelting, hydrogen is produced by chemical action with steam and diffuses in molten aluminum, which will cause inner structural defect in aluminum products. In order to avoid such defect, most aluminum factories apply dissolved gas floating method to purify molten aluminum. i.e. inert gases such as nitrogen, argon is injected into molten aluminum, and hydrogen will be brought to molten aluminum surface with spread and rise of inert gas. Graphite rotor and shaft set is necessary to inject inert gas and stir for degassing regarding both intermittent and continuous online degassing methods. Thanks to properties of heat-resistance, anti-oxidation, high strength and non- infiltration, graphite becomes the optimal choice for material of rotor and shaft, which is also named as graphite degassing rotors/impllers and shafts.
