EAA processing temperature fluctuation
Fenómeno del problema
During EAA processing temperature fluctuates ±5-8°C exceeding ±2°C control accuracy
Análisis de la causa
Improper PID parameters of the temperature control system; aged heater bands with uneven power; improper thermocouple position causing measurement deviation
Solución
1) Re-calibrate PID parameters; 2) Replace aged heater bands; 3) Adjust thermocouple position to the melt pool center
Conclusión clave
Temperature fluctuation is caused by improper temperature control system; PID calibration and heater band replacement are key
