Vacuum induction melting furnace is widely used to melt and cast permanen, nickel base material,
high temperature alloy, special steel, rare earth metal, non-ferrous metal and precise alloy under
condition of vacuum or the protective atmosphere. Also applicable to the refining treatment of metal material.
The furnace is vertical or horizontal structure, composed of furnace body, support, furnace tilting mechanism,
vacuum system, medium frequency power supply and electrical control cabinet.
1. Furnace body and cover are dual-shell configuration with the built-in water cooling jacket. Inner layer is stainless
steel with the specular polish. outer layer is high quality carbon steel with the rust-proof treatment. Water is injected into
the middle of furnace shell to cool the furnace body. furnace cover has alloy feeder, rotary viewing hole, temperature gauging
device and material beater.
2. Inductive coil is made of rectangle copper pipe rolled into the spiral structure. The crucible is put into inductive coil
(crucible and the material to fix the crucible prepared by the customer). The electric rotary apparatus drives the electrode
rotary and makes the crucible casting.
3. Vacuum system comprises oil diffusion pump, roots pump, mechanical pump, filter and controlling valves.
Using manual or automatic vacuum valves and digital display vacuometer to achieve the automatic switch
between the high and low vacuum.
