Vacuum sintering furnace safety operation procedures

Vacuum sintering furnace safety operation procedures:

1. The water source of the reservoir must be full of medium frequency power supply, vacuum furnace body, and cooling water source of the induction coil, and there shall be no impurities in the water.

2. Start the water pump to make its frequency power supply, the water circulation of the vacuum furnace induction coil and the furnace body cooling system normal, and adjust the water pressure to control at the specified value.

3. Check the vacuum pump power supply system, belt pulley belt tightness, and whether the vacuum pump oil is located in the middle line of the oil seal observation hole. After the inspection is completed, manually rotate the belt pulley of the vacuum pump, and if there is no abnormality, the vacuum pump can be started when the butterfly valve is closed.

4. Check the situation in the vacuum furnace body, and require the first-level hygiene in the vacuum furnace body, the induction ring is well insulated, the sealing vacuum tape is elastic, and the size is qualified.

5. Check whether the lever handle of the vacuum furnace body is flexible to start.

6. Check whether the rotating McNus vacuum gauge meets the requirements.

7. Check whether the graphite crucible and furnace accessories are complete.

8. After the above preparations are ready, turn on the power supply, close the intermediate frequency power supply, try to start the frequency conversion according to the intermediate frequency starting rules, and stop the frequency conversion after success, before opening the furnace.

9. The observation and temperature measurement holes on the upper cover of the vacuum furnace body need to be cleaned every time the furnace is opened for observation and temperature measurement.

10. When loading the furnace, the corresponding furnace loading method should be adopted according to different sintered products. According to the rules of the relevant material furnace loading, it shall not be changed at will.
