FAQ
Q: How long does a graphite degassing rotor last?
A: Typical service life is 1-3 months depending on operating temperature, immersion depth, and aluminum alloy type. Higher silicon content alloys and higher temperatures will reduce rotor life. Oxidation-resistant coating can extend service life by 30-50%.
Q: Can you match existing rotor dimensions from other brands?
A: Yes, we can manufacture graphite rotors and shafts to match most standard degassing equipment brands. Please provide your current rotor dimensions or send a sample, and we will produce a compatible replacement.
Q: Do you offer oxidation-resistant coating service?
A: Yes, we offer anti-oxidation coating treatment for graphite rotors and shafts. The coating forms a protective layer that reduces oxidation and erosion at high temperatures, significantly extending component service life.
