　　 It should be said that the use of vacuum furnace is more convenient, but it will inevitably affect our work due to wrong operation. Therefore, in order to save time, we must pay attention to these aspects when using vacuum furnace to avoid mistakes. Then What aspects do we need to pay attention to? Let's take a look.

　　 1. The heating element of the vacuum furnace uses low-voltage electricity, but the voltage of the power supply is still 380V, and safe electricity is still needed during operation.

　　2. Vacuum furnace is an advanced heat treatment equipment that has been developed rapidly in recent years. The workpiece is heated and cooled in an ultra-low pressure space. It has the advantages of good quality, energy saving, safety and less pollution.

　　3. When manufacturing the vacuum furnace, ensure that there is no leakage of water or gas. The vacuum furnace body and furnace cover are sealed with rubber parts, so a water barrier is required for cooling. If water leaks into the furnace, the temperature of the furnace is very high and it will cause an explosion. The workpieces processed by the vacuum furnace should be cleaned of oil stains on the surface, and at the same time, prevent the oil vapor from the quenching oil tank from entering the furnace. These oil vapors will form an explosive atmosphere after being mixed with air, and will explode when exposed to an open flame or electrified. Therefore, the door of the vacuum furnace should be closed after charging, and the furnace can be evacuated before it can be energized for heating.
