What diameter of round steel bar is suitable for heating medium frequency induction heating furnace?
Medium frequency induction heating furnace is used for bars with a diameter of 20 or more: when the bar is heated by induction, the heating is carried out along the surface of the bar. The higher the frequency, the shallower the heating depth, and the lower the frequency, the deeper the heating depth; for example, when heating with super audio equipment , The frequency is about 50KHZ, the heating depth of the bar is 2-3MM, and the core of the bar needs to be heated by the heat conduction on the surface; if the diameter of the bar is large, the temperature of the bar core is difficult to increase, and There is a large temperature difference on the surface; this problem can be solved by heating with intermediate frequency. The frequency of the intermediate frequency is 1KHZ-20KHZ, and the appropriate frequency is selected according to the diameter of the heated bar, which can ensure that the bar is heated evenly from the surface to the core;
