The intermediate frequency melting furnace is mainly used for the smelting of ferrous metals. For example, steel, ductile iron, gray iron, steel alloy, iron alloy, etc. can also be used for the smelting of non-ferrous metals such as copper and aluminum.
1 , the basic composition of the intermediate frequency melting furnace
Medium frequency power supply ( parallel intermediate frequency power supply or series intermediate frequency power supply ) , resonant capacitor bank, water cooled cable, furnace body (steel shell or aluminum shell) are mainly used in foundry enterprises, metallurgical industries, etc.
2 , furnace structure ( steel shell furnace and aluminum shell furnace )
Aluminum shell furnace body; aluminum shell, induction coil , reducer
The steel shell furnace body includes: a steel shell furnace body , an induction coil, and a magnetic field shielding system . Three major parts
3 , medium frequency power supply ,
Medium frequency melting furnace according to the power of the size can be selected KGPS frequency power supply , 12 pulse frequency power supply and a 24 pulse frequency power supply may be selected IGBT frequency power supply . The control mode of the IF power supply can be designed as local control, touch screen control, remote control, and computer control.
