Why Temperature Measurement Matters in Aluminum Forging
Accurate temperature control is critical in aluminum forging because:
- Material flowability depends heavily on forging temperature—too low leads to cracks, too high weakens mechanical properties.
- Microstructure and grain size are temperature-sensitive, directly impacting strength and ductility.
- Process efficiency: controlling temperature minimizes energy waste and rejects.
Measurement Technologies and Industrial Applications
- Infrared Pyrometry for Billets & Bars
Non-contact infrared pyrometers enable fast, accurate readings right after heating and before forging:
- Suitable for round billets or flat bars.
- High-speed detection ensures real-time monitoring without interrupting production.
- Multi-Wavelength Sensors for Emissivity Compensation
Aluminum’s reflective surface and oxidation can affect accuracy. Multi-wavelength pyrometers dynamically adjust for emissivity changes—delivering consistent readings under varying surface conditions.
Calibration, Environmental Challenges & Setup
- Emissivity and oxidation: aluminum oxide alters surface emissivity—requires adaptive sensor calibration or multi-wavelength tech.
- Environmental interference: dust, scale, and ambient heat can distort readings—proper sighting windows, shielding, or cooling jackets are vital.
- Real-time adjustment: sensors should update calibration dynamically to maintain accuracy during uneven heating.
Best Practices & Integration Tips
- Optimal placement: install sensors between furnace discharge and press to capture the true forging temperature.
- Initial calibration: start with empirical values and refine using thermocouples.
- Emissivity handling: enable automatic adjustment when oxidation starts post-furnace.
- System integration: connect sensors via analog or digital interfaces to PLC/DCS for live feedback and process control.
