How to install and use the high temperature electric furnace of vacuum heat treatment equipment?

1. After opening the package, check whether the high-temperature electric furnace is intact and whether the accessories are complete. The usual high temperature furnace does not need special installation, just lay flat on the floor or on the shelf indoors. The controller should be prevented from being disturbed, and the placement position should not be too close to the electric furnace to prevent the internal components from not working properly due to overheating.

2. A thermocouple is inserted into the hearth of the high-temperature electric furnace for 20-50mm, and the space between the hole and the thermocouple is filled with asbestos rope. The compensation wire (or insulated steel core wire) can be used to connect the thermocouple control, pay attention to the positive and negative poles, and do not connect them in reverse.

3. A power switch needs to be installed at the introduction of the power cord in order to control the main power supply. In order to ensure safe operation, the high-temperature electric furnace and the controller must be reliably grounded.

4. Before use, adjust the thermometer indicator to the zero point. When using the compensation wire and the cold junction compensator, the mechanical zero point should be adjusted to the reference temperature point of the cold junction compensator. When the compensation wire is not used, the mechanical zero point should be adjusted. Zero scale, but the indicated temperature is the temperature difference between the measuring point and the cold junction of the thermocouple.

5. After checking the wiring and confirming that it is correct, cover the controller shell. Adjust the setting pointer of the temperature indicator to the desired operating temperature, and then turn on the power. Turn on the power switch, the green light on the temperature indication surface is on, the relay starts to work, the high-temperature electric furnace is energized, and the ammeter shows current.
