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

2. The heater of the vacuum furnace uses low-voltage electricity, but the power supply voltage is still 380V, so it is necessary to use electricity safely during operation.

3, vacuum furnace manufacturing, should ensure that no air leakage, no water leakage. The sealing of vacuum furnace body and furnace cover is made of rubber, which needs water interlayer cooling. If water leaks into the furnace, the temperature of the furnace will be very high, which will cause an explosion. The workpiece treated by vacuum furnace should be cleaned of oil stains on the surface, and at the same time, the oil vapor in quenching oil tank should be prevented from entering the furnace. These oil vapors will form an explosive atmosphere when mixed with air, which will explode once there is open fire or electricity. Therefore, it is necessary to close the oven door after the vacuum furnace is powered on, and it can only be powered on and heated after vacuum pumping.
