The main advantages of copper ingot induction heating furnace using medium frequency induction heating power supply are:

◆　High power, low frequency, good heat permeability, fast heating speed and high production efficiency;

◆　Using voltage feedback series resonant circuit and IGBT frequency conversion, the conversion efficiency is as high as 90% or more;

◆　With the function of automatic frequency tracking, high power factor can always be guaranteed in the whole process, regardless of the output power, the power factor is always greater than 0.9;

◆　Compared with thyristor intermediate frequency furnace, it can save energy by 10%-30%, and the startup success rate under any load is high;

◆　The high-order harmonic components are small, and the impact on the power grid is small;

◆　The copper rod forging and heating equipment has a complete protection circuit and high working reliability;

◆　The power part adopts modular design, which is convenient for maintenance;

◆　Compared with other traditional heating methods, the copper ingot induction heating furnace has less oxide layer to heat the workpiece, which can improve the processing quality of the workpiece, save energy and raw materials, easily realize mechanization, automation and flow production, reduce labor intensity, and improve the production environment.
