Vacuum melting furnace structure characteristics

vacuum induction melting furnace

vacuum induction melting furnace

Vacuum furnace of the furnace body is an induction coil, by manual rotation handle outside the furnace can be easily within the crucible melting liquid poured into the mold, mold can be designed to be cooled. Upper crucible is equipped with a temperature measuring device. By secondary pump, vacuum system, K – 300 oil diffusion pump and 2 x – 70 mechanical pump, mechanical pump is equipped with electromagnetic relief valve on the return oil after avoid blackouts. With bleed valve and charging valve on the vacuum unit.
Vacuum melting furnace structure, this product is made up of furnace cover, furnace, furnace bottom, slewing mechanism of crucible, vacuum system and intermediate frequency power supply control system, etc.
Furnace cover, furnace, furnace bottom adopts double water cooling structure, keep the temperature of the bof shell is not more than 60 ℃. Furnace cover opened the way for manual and the furnace cover with observation holes and damper, to facilitate adding alloying elements to the process of melting, furnace cover on AD hoc alloy feeder. Furnace is an induction coil, by manual rotation handle outside the furnace can be easily within the crucible melting liquid poured into the mold, mold can be designed to be cooled. Upper crucible is equipped with a temperature measuring device.
By secondary pump, vacuum system, K – 300 oil diffusion pump and 2 x – 70 mechanical pump, mechanical pump is equipped with electromagnetic relief valve on the return oil after avoid blackouts. With bleed valve and charging valve on the vacuum unit. Medium frequency power supply can choose KGPS SCR or IGBT integration power supply, digital circuit, such as electrical system with over-current, over-voltage feedback and protection circuit.
