high temperature mesh belt furnace of commissioning and startup operation steps

Commissioning and startup operation steps

1. Turn on the power. Check whether there is short circuit or leakage before connecting the power supply.

2. Put the "power" switch at the "on" position, and the temperature display and regulation instrument is charged. Set the temperature and temperature time curve according to the requirements. Refer to the operation manual of the intelligent temperature controller for specific operation.

3. Press the "heating start" button to check the temperature rise of the working room.

4. When the electric furnace is used for the first time or used again after long-term shutdown, it must be dried. Before drying the furnace, use a multimeter to measure the resistance between the incoming and outgoing lines of the power supply and the high-temperature furnace shell. Short circuit is not allowed. Oven drying must be carried out according to the following procedures:

1) From the chamber to 200 ℃ (adjust the temperature controller to set the temperature, the same below), keep the temperature for 2 hours, open the furnace door, so that most of the moisture in the furnace evaporates.

2) From 200 ℃ to 500 ℃, keep temperature for 3 hours, open the furnace door regularly until there is no moisture in the furnace.

5. Check the temperature display of the temperature display regulator. After reaching the set upper limit temperature, stop the indicator light and stop heating. After reaching the set lower limit temperature, the heating indicator light should be on and start heating.

6. Press the "heating stop" button to stop heating.
