High Temperature Vacuum Induction Melting Furnace, Medium Frequency up to 2000℃
This vacuum induction melting furnace adopts the theory of medium frequency induction heating and builds a high vacuum system so that the metal can be melted under a high vacuum situation. This furnace is widely used in many kinds of research and production, such as nickel and special steel, precision alloy, activity metal, high temperature alloy, magnet material, etc. Also suitable for the vacuum precision cast of small parts.

Features
- Adopt IGBT or KGPS medium frequency power supply, the max temperature is 2000℃.
- The vacuum system is composed of a mechanical pump, roots pump, and diffusion pump, the max vacuum level is 7×10^(-3)Pa.
- The alloy feeder is built inside. The material can be fed into the melting crucible by operating the feeder handle.
- The furnace cover is equipped with an observation window, easy to observe the performance of the furnace.
- An induction heater consists of a rectangular copper tube, through the two mating nuts fixed on the electrode, easy to disassemble.
- The crucible could be placed inside the inductor. The crucible material should follow the melt alloy type.
- Secondary direct feeding support.
