EEA Processing Temperature Fluctuation

문제 현상

During EEA processing, temperature fluctuates ±5-8°C, exceeding the ±2°C control accuracy

원인 분석

Improper PID parameters of the temperature control system; aging heater bands, uneven power; improper thermocouple position, measurement deviation

해결 방법

1) Re-tune the PID parameters; 2) Replace aging heater bands; 3) Adjust the thermocouple position to the melt pool center

핵심 요약

Temperature fluctuation is caused by improper temperature control system; PID tuning and heater band replacement are key
