Construction safety management: safe operation of vacuum heat treatment furnace

真空加热炉.jpgVacuum heat treatment furnace is an advanced heat treatment equipment developed in recent years. The workpiece is heated and cooled in the space of ultra-low pressure. It has the advantages of good quality, energy saving, safety and pollution.

Although the heating body of the vacuum furnace is low voltage, the power supply voltage is still 380V, and it still needs safe electricity when operating.

When the vacuum furnace is made, make sure that the air is not leaking and not leaking. The sealing of the vacuum furnace body and the cover of the furnace is made of rubber, so it needs to be cooled with the water barrier. If the water is leaking into the furnace, the temperature of the furnace is very high and it will cause an explosion. The workpiece of the vacuum furnace should clean the surface oil, and avoid the oil vapor from the quenching tank into the furnace. The mixture of oil and air will form an explosive atmosphere, which will explode when there is an open fire or electricity. Therefore, the furnace door should be closed after the vacuum furnace charge and the furnace can be pumped into a vacuum before the electric heating can be energized.
