Technicalscheme of vacuum induction melting furnace
I.Overview:
Thevacuum induction melting furnace uses the principle ofuency induction heating to melt and vacuum cast metal in avacuum state or under the protection of inert gas.
Thisvacuum induction melting furnace is of intermittent structure witha rated capacity of 500 kg. Under vacuum (or inert atmosphere)conditions, different metals such as super alloys,nickel-based alloys, cobalt-based alloys, stainless steel, steel,iron, copper, aluminum, magnesium, lithium, and titanium alloys canbe smelted.
Inthe smelting process, without affecting the vacuum of the smeltingvacuum chamber, temperature measurement, supplementary feeding,alloy feeding and sampling can be realized. Auxiliary functionssuch as mold heating.
Vacuuminduction melting furnace, vacuum melting, vacuumcasting.
Vacuuminduction melting furnace is complete, mainly composed of meltingcasting chamber, intermediate frequency power supply, inductionmelting furnace, tilting furnace casting system, main feedingsystem, vacuum isolation valve, metal temperature measurement,vacuum system, hydraulic system, electric control system, coolingsystem , Pneumatic system, working platform, etc.
