Introduction to Graphite Rotor and Shaft

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.

Advantages of Yinxuan Graphite Rotor and Shaft

● Best raw material
Based on rich experience and deep understanding of aluminum degassing procedure, we produced specialty graphite material specially used for machining aluminum degassing graphite rotors and shafts.
Such graphite material is with advantages of high strength, high hardness, good heat-resistance, low porosity, anti-abrasion and anti-scour.

● Precise machining
Machining process strictly conforms to customers' drawings. After machining, different parts match perfectly with high concentricity, which avoids damage caused by mechanical stress to the graphite rotor and shaft.

● Special Treatment
■ Impregnation Anti-oxidation Treatment. To extend service life of graphite rotor and shaft, Yinxuan Carbon proprietary technology and nanometer anti-oxidant are applied to fill pores of graphite material and cover surface of graphite rotor and shaft, which improves its properties of heat-resistance, anti-oxidation and anti-scour.
■ Coating anti-oxidation Treatment. Yinxuan Carbon proprietary coating material is applied to already impregnated anti-oxidation graphite rotor and shaft except threads. The coating material is non-infiltrated with aluminum, but well adhered to graphite material. Besides, the coating material is with better performance than graphite material on aspects of heat-resistance, anti-oxidation, anti-corrosion and anti-scouring. As a result, the lifespan of graphite rotor and shaft with surface coating is further extended.
■ Partial strengthening Method. According to end-users' application situation, we strengthen the most easily consumed position to get the longest service life with lowest cost.
Cost efficiency of Yinxuan graphite rotor and shaft is in a world leading level.
