Multipurpose furnace production line

Multipurpose furnace production line safety operation specification explanation

Multi-purpose furnace production line starting operation:

All components must be thoroughly inspected before starting the equipment each time, and damage to structural components can lead to operational failure and major damage.

Multipurpose furnace production line preparation:

- The furnace door must be open;

- Install the removed red bend;

- Check the reserves of process media;

- Check nitrogen reserves;

Ring furnace

Furnace Starting:

1. Power on.

2, turn on "control voltage on", "inverter power on".

3. After the system is started, open the fan in the rear chamber, turn the oil agitator to automatic, turn the fan in the front chamber to automatic, and start the oil cooling pump.

4, a comprehensive inspection of the mechanical actions (lifting platform, middle door, push zipper operation; The smooth operation and noise of the circulating fan and oil stirring are normal, and the abnormal situation is handled in time to ensure the normal operation of the equipment.

5, turn on the "heating control on", start the chamber temperature control, according to the multi-purpose furnace heating curve.

6, start the oil tank heating, and check whether the quenching oil level reaches the standard oil level after the oil temperature reaches the set value. If the oil level is too low, the quenching oil should be added in time to make the oil level reach the required height.

Note: The quenching oil level is subject to the slow stirring speed of the oil mixer.

7. At the same time, check whether the gas supply pressure of the gas distribution system is normal to ensure the normal gas supply of the equipment. After 400℃, a small amount of nitrogen should be introduced to protect the inner components of the rear chamber furnace.

8, open the exhaust gas burner stop valve, press the "exhaust gas ignition" button to light the exhaust gas burner, check whether the burner is stable, open the stop valve of the front door fire curtain, press the red indicator light on the flame controller, close the front door after the fire curtain burns, open the front door again after the front room ventilation is completed, and observe whether the fire curtain and the front door interlock are normal, and whether the high-pressure nitrogen charging in the front room is normal. Whether the anterior chamber ventilation time is correctly executed. When closing the front door, check whether the furnace pressure is normal. Under normal circumstances, the nitrogen flow rate of about 3M3/h should be able to reach about 240Pa.
