Engineering Risks & FAQ - **Caution**: - **Caution**: - **Caution**: ### Q: What gases does this degassing system remove from molten metals? **A**: Our system effectively removes hydrogen, oxygen, and nitrogen gases that become dissolved in molten aluminum, copper, steel, and other non-ferrous metals during melting processes. ### Q: How does the refractory lining protect the degassing chamber? **A**: The refractory lining provides thermal insulation and chemical resistance against molten metal temperatures up to 1600°C, preventing thermal shock and extending the system's operational lifespan. ### Q: What maintenance is required for the graphite rotors? **A**: Graphite rotors typically require inspection every 200-300 operating hours and replacement every 800-1000 hours, depending on metal type and operating temperature. Regular cleaning prevents buildup and maintains optimal gas removal efficiency. ## 6.
