What are the functions and classifications of a vacuum furnace?
What are the functions of a vacuum furnace? What are the main categories?
China's industrial development is more and more rapid, the application of vacuum furnace is more and more widely, so do you understand the vacuum furnace?
Vacuum furnace is generally composed of main engine, furnace chamber, electric heating device, sealed furnace shell, vacuum system, power supply system, temperature control system and outside furnace transport vehicle. The sealed furnace shell is welded with carbon steel or stainless steel, and the joint surface of the removable parts is sealed with vacuum sealing material. In order to prevent the shell from deforming and the sealing material from deforming, the shell is usually cooled by water or air cooling. The furnace is located in the sealed furnace shell. According to the purpose of the furnace, there are different types of heating elements inside the furnace, such as resistance, induction coil, electrode and electron gun. Crucible is installed in the chamber of vacuum furnace for smelting metal, and some of them are also equipped with automatic pouring device and loading and unloading manipulator. The vacuum system is mainly composed of vacuum pump, vacuum valve and vacuum gauge.
How many kinds of vacuum furnaces do you know?
There are many kinds of vacuum furnace, including vacuum quenching furnace, vacuum brazing furnace, vacuum annealing furnace, vacuum adding magnetic furnace, vacuum tempering furnace, vacuum sintering furnace, vacuum diffusion welding furnace and vacuum carburizing furnace. If classified according to heating methods, it can be divided into vacuum resistance furnace, vacuum induction furnace, vacuum arc furnace, vacuum consumable electric arc furnace, electron beam furnace (also known as electron bombardment furnace) and plasma furnace.
What are the functions of a vacuum furnace?
Vacuum quenching (tempering, annealing) : it is a treatment method to achieve the expected performance by heating and cooling materials or parts in vacuum according to the process rules.
Vacuum brazing: it is a welding process in which a group of welding parts are heated to the temperature above the melting point of the filler metal but lower than the melting point of the base metal under the vacuum state, and the wetting and flow of the filler metal to the base metal form a weld.
Vacuum sintering: it is a method of heating metal powder products under vacuum and making adjacent metal powder grains become parts by adhesion and diffusion.
Vacuum magnetization: it is mainly used for magnetization of metal materials
