Vacuum Induction Melting Furnace
Arc Remelting
Brief Description
Vacuum arc remelting (VAR) is the continuous remelting of a consumable electrode by means of an arc under vacuum. The advantages of arc melting are its highly concentrated energy and its straightforward control procedures. Jen Long VAR furnace overcomes serious problems that have been historically associated with conventional VAR operations after continuous research and development. Jan Long offers innovative technology in system design and process control, which operate exclusively in vacuum, thus, special steel, super alloys, Fe-, Ni-, Co-, and Ti-base alloys for high strength and temperature-resistant components achieve quality advances. Therefore, the VAR, which Jen Long has developed and applied for solving all of problems, has been used in related field for many years.
Application
- Super alloys for the chemical industry
- Special alloys for the electronics industry
- Special alloys for aerospace
- Structural steels for turbines and generator shafts
- Melting of reactive metals (titanium, zirconium and their alloys)
Advantage
- Removal of dissolved gases, such as hydrogen and nitrogen.
- Minimizing the content of undesirable trace elements with high vapor pressure.
- Improvement of material cleanness.
- Directional solidification, less segregation.
