Summary:PURPOSE: To provide an induction heating system of variable forging billets with dual type frequency to produce forging products of high quality by generally heating forging billets of various dimensions in one induction heating furnace. CONSTITUTION: In an induction heating system(100) of variable forging billets with dual type frequency in which forging billets are heated by high frequency induction heating, the induction heating system comprises a power supply part(300) for oscillating high frequency current of 900 to 1300 Hz at 400 to 550 Hz; first and second induction heating furnaces(400,410) for heating charged forging billets respectively through high frequency current of 400 to 550 Hz or 900 to 1300 Hz impressed from the power supply part; and charging device(500) and discharging device(600) installed in front and rear of the first and second induction heating furnaces to charge the forging billets into the first and second induction heating furnaces or discharge the forging billets from the first and second induction heating furnaces.
