Maintenance and precautions of vacuum heat treatment equipment

Maintenance and precautions of vacuum heat treatment equipment

 

1. The machine should be used by a special person. When the electric furnace is first used and used again after a long period of non-use, it must be oven-baked. The oven temperature is 2 hours at 200 °C, and 2 hours at 200-600 °C. The furnace temperature should not exceed the rated temperature during use, so as to avoid burning out the heating element.

 

2. Regularly check whether the connection of the electric furnace and the controller is in good condition, indicating whether the instrument is stuck when moving, and use the potential difference needle to check whether the scale error of the indicating instrument increases.

1. Before powering on, check whether the wiring is in compliance, whether the wiring screws of the controller are loose, and whether there is a power failure or leakage.

 

2. Put on both hands with insulating gloves, and check that the table and floor are dry, and the floor has been covered with rubber pads. After checking and confirming the switch position of the muffle furnace to be used, confirm that the main power has been turned off and cut off.

 

3. Weigh the sample into the furnace, close the furnace door, and turn on the electric furnace switch;

 

4. "Set" the switch on the controller to the target test temperature;

 

5. After the setting is completed, the electric furnace starts to heat up, and the meter is displayed by the green indicator light;

 

6. After the working time is up, turn off the main power of the electric furnace, and take out the burned samples;

Safe operation method of vacuum heat treatment equipment

 

1. Do not exceed the limit temperature of the resistance furnace during use.

 

2. Be sure to cut off the power supply when loading and taking samples to prevent electric shock.

 

3. When loading and taking samples, the opening time of the furnace door should be as short as possible to prolong the service life of the electric furnace.

 

4. It is forbidden to pour any liquid into the furnace.

 

5. The samples stained with water and oil shall not be put into the furnace; the samples shall not be loaded with clips stained with water and oil.

 

6. Wear special gloves when loading and taking samples to prevent burns.

 

7. The sample should be placed in the middle of the furnace, neatly placed, and should not be placed randomly.

 

8. Do not touch the electric furnace and the surrounding samples casually.

 

9. Cut off the power supply after use.

 

10. Non-operators are not allowed to operate the resistance furnace, and operate in strict accordance with the operating procedures of the equipment.
