Characteristics of high temperature vacuum furnace

Now many processing plants will use vacuum furnace, used to do vacuum brazing, vacuum annealing, vacuum aging and other processing, the following describes the principle and advantages of high temperature vacuum furnace equipment.

Introduction to the principle of vacuum furnace

Vacuum furnace: that is, in the specific space of the furnace chamber, the vacuum system (composed of vacuum pump, vacuum measuring device, vacuum valve, furnace body, control system and other components after careful assembly) will discharge some substances in the furnace cavity, so that the pressure in the furnace chamber is less than a standard atmospheric pressure, and the space in the furnace cavity can realize the vacuum state. This is the vacuum furnace. Industrial furnace heated by electric heating element in vacuum state, equipment for heating in vacuum environment.

Equipment supply classification of high temperature vacuum furnace

Vacuum furnace, namely vacuum heat treatment furnace, can be divided into the following two types according to the commonly used industrial equipment: horizontal vacuum furnace and vertical vacuum furnace.

Advantages of using high temperature vacuum furnace

(1) Many other equipment may pollute the environment, and at the same time need to carry out three wastes treatment, but the use of vacuum furnace can solve this problem very well.

(2) Compared with salt bath furnace, the energy consumption of vacuum furnace is obviously reduced. The modern advanced vacuum furnace heating chamber adopts the heat insulation screen made of high-quality heat insulation material, which can highly concentrate the electric heating energy in the heating room.

(3) The furnace temperature and precision monitoring have been improved significantly. The temperature difference between different parts of a large number of workpieces in the furnace is relatively large. Generally, the temperature difference of horizontal vacuum furnace is ± 3 ° C and that of vertical vacuum furnace is ± 7 ° C. if setting means are adopted, the temperature difference can still be controlled within ± 5 ° C.

(4) Based on the improvement of temperature measurement and control accuracy, workpiece movement, air pressure regulation and power regulation can be programmed in advance, and quenching and tempering can be implemented step by step.

(5) For the oxidation and decarburization of the workpiece surface during heating, a clean surface without deterioration layer can be obtained. This has a great effect on the improvement of the cutting performance of the tools which only grind one side during grinding.
