What is the relationship between the heating time and frequency of an induction heating furnace?

The time required for the heating blank of the indüksiyon isitish pechkasi to be heated from the initial temperature (here 600 ℃) to the forging temperature with a given core surface temperature difference is called the heating time. Under the premise of a given core surface temperature difference (such as a 100 ℃ temperature difference specification), the heating time depends only on the frequency of the current (which determines the depth of current penetration), the physical properties of the blank (thermal conductivity), and the diameter of the blank (the diameter of the blank). The diameter minus the depth of current penetration determines the distance over which the average heat conducts).
