The invention relates to the technical field of
induction heating cored induction furnaces, in particular to a cored
induction furnace melting starting power source device. The cored
induction furnace melting starting power source device comprises an induction
voltage regulator, an on and off switching unit, a control and display unit, a frequency converter and a
voltage regulating driving motor. Compensation capacitors C are connected with the two ends of an
inductor coil L of an cored
induction furnace in parallel, a factory power source and a
heating power source supply power to the
inductor coil L through the on and off switching unit, the on and off switching unit controls connection and disconnection of the factory power source and the
inductor coil L or the
heating power source and the inductor coil L, the control and display unit monitors the output power of the on and off switching unit and outputs signals to the frequency converter, and the frequency converter controls the
voltage regulating driving motor to rotate so as to realize adjustment of the output voltage of the induction
voltage regulator. Due to the fact that the induction
voltage regulator is adopted to adjust the output power of the factory power source, the output power of the factory power source can gradually increase from zero, and the phenomenon of channel breakage caused by the fact that the initial power is too high is effectively avoided.
