Vacuum furnace works

Vacuum furnace generally by the host, furnace, electric devices, sealed furnace shell, vacuum system, power supply system, the furnace temperature control system and truck components. Sealed furnace shell welded carbon steel or stainless steel, removable parts joints sealed with vacuum sealing material. After the furnace shell to prevent thermal deformation and metamorphism heat sealing materials, furnace shell is generally cool with water or air cooling. Hearth furnace located sealed envelope. According furnace use, installed inside the furnace heating elements of different types, such as resistors, induction coil, and the electron gun electrodes. Metal smelting furnace built with vacuum furnace crucible, some also equipped with automatic pouring device and the loading and unloading of robots. Vacuum system consists of vacuum pumps, vacuum valves and vacuum gauges and other components. 
Vacuum furnace that works by extracting vacuum, forming a nearly destroy ocean air low pressure environment, and then use the water at low pressure (less than atmospheric pressure) low boiling to produce steam, condensation heat transfer by way of soft drinks heat output operates on the principle of work.
Compared to other types of furnaces, vacuum furnace has several significant advantages: no pollution to the environment, without the need for waste treatment; the use of high quality insulation material insulation walls and barriers, low energy consumption and therefore energy savings significantly; high precision temperature control and so on.
