1. Machine OverviewThis equipment uses nitrogen gas to degas molten aluminum and a rotor for stirring, improving metal quality for casting. Key components include the degassing unit, stirring mechanism, control panel, and safety features.2. Safety Precautions
  • Wear heat-resistant PPE (gloves, face shield).

  • Ensure proper ventilation to avoid nitrogen buildup.

  • Only trained personnel should operate.

  • Inspect for gas leaks or damage before use.

  • Know the emergency stop procedure.

3. Operating InstructionsStep 1: Preparation

  1. Check rotor, gas lines, and crucible for damage.

  2. Connect high-purity nitrogen (≥99.99%) and set pressure (0.2–0.5 MPa).

  3. Power on and set molten aluminum temperature (680–750°C).

Step 2: Degassing

  1. Submerge rotor/lance (2/3 crucible depth).

  2. Set nitrogen flow (10–20 L/min) and rotor speed (200–600 RPM).

  3. Degas for 5–15 minutes, monitoring slag formation.

  4. Verify hydrogen content (≤0.15 ml/100g Al) with an analyzer, if available.

Step 3: Stirring

  1. Switch to stirring mode, set rotor speed (100–300 RPM).

  2. Stir for 3–10 minutes for uniform mixing.

  3. Stop and raise rotor.

Step 4: Shutdown

  1. Close nitrogen valve and power off.

  2. Clean rotor/lance of slag.

  3. Inspect and store in a dry environment.

4. Troubleshooting

  • Poor Degassing: Increase flow/time or check for leaks.

  • Uneven Mixing: Adjust rotor speed or submersion.

  • Noise/Vibration: Stop and inspect rotor/motor.

  • Low Gas Pressure: Replace cylinder or check lines.

5. Best Practices

  • Adjust parameters for alloy type and crucible size.

  • Clean after 50–100 cycles.

  • Use hydrogen analyzer for quality control.

  • Follow local slag disposal regulations.

6. ConclusionThis machine ensures high-quality aluminum castings through effective degassing and stirring. Refer to the manufacturer’s manual for model-specific details.Note: For tailored instructions or specific model details, provide additional information.
