EEA Processing Temperature Fluctuation
Fenómeno do problema
During EEA processing, temperature fluctuates ±5-8°C, exceeding the ±2°C control accuracy
Análise das causas
Improper PID parameters of the temperature control system; aging heater bands, uneven power; improper thermocouple position, measurement deviation
Solução
1) Re-tune the PID parameters; 2) Replace aging heater bands; 3) Adjust the thermocouple position to the melt pool center
Conclusão principal
Temperature fluctuation is caused by improper temperature control system; PID tuning and heater band replacement are key
