What are the main characteristics of vacuum induction furnace?

What are the main characteristics of vacuum induction furnace. The pressure inside the chamber of a stove or furnace smoke into industrial furnace is lower than the atmospheric pressure. Vacuum furnace heating power, the heated workpieces appearance no oxidation, no decarburization, small deformation, the mechanical performance is good. Use the vacuum furnace smelting metal is beneficial to remove impurities, less finished pinhole, segregation of small, good quality. Vacuum furnace is suitable for the high quality, high purity, refractory metal melting and heating, such as tungsten, molybdenum, tantalum, niobium, titanium, heat-resistant alloy steel exercise and magnetic materials, electrical materials of high strength steel, stainless steel, tool steel and die steel, heat treatment.
  Vacuum furnace usually by the chamber of a stove or furnace, heating equipment, sealing furnace shell, vacuum system, power supply system and temperature control system, etc. Sealing furnace shell made of carbon steel or stainless steel welding is removable parts of joint face seal with vacuum sealing material. In order to avoid heated furnace shell deformation and disintegration sealing material is heated, usually with water-cooled or air-cooled cooling furnace shell. Chamber of a stove or furnace located sealing furnace shell. According to use the stove, inside the furnace is equipped with different types of heating element, such as resistance, electrode and electron gun. Metal smelting in a crucible furnace, vacuum furnace of some manipulator with active casting equipment and loading. Vacuum system is mainly composed of vacuum pump, vacuum valves and vacuum gauge, etc.
