Laboratory vacuum induction melting furnace
Application：
Utilizing the principle of medium frequency induction heating under the vacuum condition, the furnace is experimental device
which mainly used to smelt the metal.
It is applicable to scientific research & production unit to melt and cast nickle-base alloy, special steel, precise alloy,
high temperature alloy, rear earth metal, neodymium iron boron and magnetic material etc.
Features：
1.It is made up of furnace door and its opening closing device, furnace body(including casting chamber), furnace stand, inductor,
tilting casting apparatus, vacuum system, medium frequency power and electrical control system.
2.Alloy feeder, rotary viewing window and temperature measuring device are installed on the furnace body. Furnace door is joined
with furnace body by the hinge.The door is opened or shutted by means of the handle.
3.Rectangle copper pipe is wound into the spiral indcutive coil. The crucible is put into the coil.When the casting,turning hand lever
installed outside of the furnace to get the electrode rotated to tilt the crucible to cast.
4.Vacuum system is composed of diffusion pump, mechanical pump and vacuum valves. Using pneumatic or manualvacuum valves
and digital display vacuum gauge to automatically switch the lower to higher vacuum.Power equipped with IGBT medium frequency
power supply system.
