Graphite Rotor

Core Value and Machining Advantages

1. Precision Machining and Dynamic Balancing Assurance
   Using multi-axis high-precision CNC machining, we guarantee rotor shaft concentricity, blade symmetry, and mounting-interface accuracy. High-grade dynamic balancing correction ensures smooth operation with minimal vibration at speeds up to 500–700 RPM, significantly extending the drive system’s service life.
2. Exceptional Thermal Shock and Erosion Resistance
   Selected high-strength, fine-grained graphite materials provide outstanding thermal shock resistance, enduring frequent rapid heating and cooling. The graphite surface is non-wetting to molten aluminum, effectively resisting erosion from high-temperature aluminum melt and flux salts. Service life far exceeds that of metal rotors.
3. Hydrodynamic Optimization Design
   Based on your degassing system model and process requirements, we offer optimized rotor-blade design services:
   • Blade Profile: Optimized blade angle, shape, and quantity for optimal gas dispersion and melt circulation efficiency.
   • Flow Path Design: Precisely machined internal gas channels ensure uniform and stable argon/nitrogen gas ejection through the rotor blades.
   • Custom Interfaces: Accurately machined threads or flange connections for reliable drive coupling.
4. Scientific Material Matching
   • High-Density, High-Strength Graphite: The standard material for rotor manufacturing, balancing wear resistance and thermal shock resistance.
   • Oxidation-Resistant Coated Rotors: Special anti-oxidation coatings can be applied to protect the rotor during air exposure (e.g., preheating, shutdown), further extending overall service life.

Primary Application Scenarios

• Aluminum and Aluminum Alloy Melting & Casting
  Used as core rotating components in online degassing units and holding-furnace purification systems for producing high-end sheet, foil, aerospace-grade aluminum, automotive aluminum, and more—critical for improving material purity.
• Zinc and Zinc Alloy Melting
  Applied in purification systems for continuous galvanizing lines (e.g., Sendzimir process).
• Special Metal and Alloy Melting
  Suitable for copper alloys, magnesium alloys, and other specialty melting processes where strict control of melt gas content is required.
