Precautions for the operation of tempering furnace:

1. Before the tempered workpiece enters the furnace, power on the distribution box and drive out the turning trolley to check whether the instruments and meters are normal (set temperature value), and whether the fan motor and heater are in good condition.

2. It is required to be placed neatly and not skewed during installation. The height should be 100 mm without the power supply in the furnace after entering the furnace.

3. When returning the trolley to enter the furnace, go slowly. Observe whether the trolley entering the furnace is running smoothly and whether the power cord is blocked by the chain. After entering the furnace, close the door, turn on the fan motor, adjust the temperature, and use the thermometer.< br />

To correct the temperature.

4. When the tempering is finished, first turn off the heating switch and then turn off the fan motor, then open the door and drive out the trolley.

5. After loading and unloading the product in the furnace, it is necessary to check whether the thermocouple is inserted into the tempering furnace (the thermocouple is the data value of the measured temperature), and be careful not to touch the thermocouple (the workpiece is not allowed to contact the thermocouple)< br />

.

6. Every 1 hour in the tempering furnace, the staff on duty must observe whether the temperature of the tempering furnace is normal.

7. When the circuit fails or fires due to the failure, turn off the switch to extinguish the fire. When the furnace catches fire, immediately open the door to drive the trolley out, and close the switch to extinguish the fire.

8. When the electrical system fails, all repairs should be done by electricians. Non-electrical personnel are strictly prohibited to repair by themselves.
