Start the atmosphere mixers of furnace 1-4 in sequence and check for smooth operation without any abnormal sounds.
4. Initiate the main furnace heating system and heat up in segments according to the set temperature control curve.
- 400℃ stage: Insulation for 2 hours (for further removal of residual moisture and elimination of low-temperature stress).
- At 600℃ stage: Insulate for 2 hours (to promote even expansion of the furnace material).
- 800°C stage: Insulate for 2 hours (reaches working temperature, ready to establish atmosphere).
**(II) Carbon Potential Control System Operation**
1. Turn on the carbon potential control cabinet power, and set the target process carbon potential value on the control interface (e.g., 1.0%C).
2. Once the main furnace temperature stabilizes at 800°C, gradually open the pipeline valves and adjust the drip flow to the recommended process value (e.g., 100-120 drops per minute) based on the flowmeter indication.
Daily Motto: Actions speak louder than words.
