High Quality Industrial Vacuum Furnace Large vacuum heat treatment furnace China wholesale

Large vacuum heat treatment furnace Details.

Large vacuum heat treatment furnace vacuum heat treatment, that is, vacuum technology and heat treatment of two professional combination of integrated technology, refers to the heat treatment process in whole and in part in a vacuum state. Vacuum heat treatment furnace thermal efficiency, can achieve rapid heating and cooling, can achieve no oxidation, no decarburization, no carburization, can remove the phosphorus chips on the surface of the workpiece, and degreasing and degassing, etc., so as to achieve the effect of surface brightness and purification.

Safety operation of large vacuum heat treatment furnace

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

2, the vacuum furnace heating body with low-voltage electricity, but the supply voltage is still 380V, the operation still needs to be safe with electricity.

3, vacuum furnace manufacturing, should ensure that no gas, no water leakage. Vacuum furnace body and cover, etc. sealing is with rubber parts, so you need to use water compartment for cooling. If water leaks into the furnace chamber, the furnace chamber temperature is very high, it will cause an explosion. Vacuum furnace treatment of the workpiece, should clean the surface oil, while avoiding the quenching oil tank oil vapor into the furnace chamber. These oil vapor and air mixed will form an explosive atmosphere, once there is an open flame or electricity will be generated when the explosion. So the vacuum furnace charging should be closed after the furnace door, the furnace chamber into a vacuum before power heating.
