Vacuum Medium Induction Melting Furnace
I. Usage
The furnace is periodic operating, providing vacuum or protective atmosphere in which the alloy steel, nickel base alloy, lanthanon and others can
smelt and cast. Besides, it can be also used in metal materials’ refining.

III. Structure Description
1. ZGS-3 is horizontal furnace, the rest are all vertical furnace.
2. The furnace are mainly made up of furnace shaft, furnace binding, inductor, furnace tilting mechanism, vacuum system, forehearth operating
cabinet and intermediate frequency power supply. Both the shaft and furnace cover are double watercooled structure, the internal layer is
stainless steel, the external layer is protected from rust by using high carbon steel, and the middle is used forwater cooling. Alloy feeder head,
revolving window, thermocouple measuring mechanism, feeding rod ( ZGS-50\ ZGS-150 and ZGS-200) and others are installed on the furnace
cover.
3. The induction coil is helical heterotype copper pipe. Shaped crucible or knotting crucible are put in the induction coil. Electrode rotary and
crucible’s tilting are achieved by external manual or electric when casting.
4.Vacuum system is made up of oil diffusion pump, Roots pump, mechanical pump, strainer and various control valves etc. Pneumatic operation
baffle valve and digital vacuometer can switch over the high and low vacuum automatically. Intermediate frequency power supply includes IGBT and
KGPS transistor. The first one has the features of energy-saving, space-saving and cooling-free, and the second one is of low cost in maintenance.
