Precautions for management and maintenance of high temperature electric furnace

Precautions for equipment management and maintenance of high temperature electric furnace and muffle furnace
  1. The high temperature electric furnace controller should not be placed on the electric furnace, so as not to affect the normal operation of the controller. It should be placed on a flat workbench or fixed on the wall, and should not be too far away from the high-temperature electric furnace.
  2. The load capacity of the power cord, switch and fuse connected to the controller and the electric furnace should be slightly larger than the rated power of the electric furnace.
  3. When wiring, first loosen the bolts on the side of the shell, remove the side plate, the power cord passes through the wiring hole on the side plate, and then connect the power cord.

  4. After checking that the wiring is correct, the power can be turned on. First, turn on the power switch, and then press the button switch on the control panel to adjust the high temperature electric furnace meter setting button to set the temperature to the required degree.
  5. Check whether the broken couple protection device is working normally. The method is: loosen one end of the thermocouple of the high temperature electric furnace. At this time, the temperature measurement indicator will quickly rise to the highest point and the heating power will be automatically cut off. After even, the high-temperature electric furnace can work normally.
  6. Oven, when the electric furnace is used for the first time or used again after long-term inactivity, it must be oven baked. The process is: when the room temperature rises to 200 ℃ for 4 hours, open the furnace door to let the water vapor escape; when the temperature is 200 ℃ to 600 ℃ for 4 h, close the furnace door; when the temperature is 600 ℃ to 800 ℃ for 2 h, Close the furnace door.
  7. After use, turn off the button switch on the control panel of the high temperature electric furnace , and then cut off the main power switch.
