induction hardening machine heating principle

induction hardening machine induction heating, induction heating principle engineer explained that:heat treatment equipment the workpiece into the sensor, the sensor input is generally intermediate frequency or high frequency alternating current (1000-300000Hz or higher) hollow brass. Generating an alternating magnetic field with the frequency of the induced current in the workpiece, the workpiece induced current distribution is uneven, the surface of strong, weak in the interior,Induction soldering equipment the center portion close to 0 by using the skin effect enables rapid heating of the surface, the surface temperature within a few seconds up to 800-1000 o C, and the temperature rise is small core parts.
