Why is the workpiece not placed in the medium frequency induction heating furnace?

First, it must be ensured that the heated billet is metal-guided,

Second, ensure that the equipment can operate normally.

Third, the blank and the heating coil ensure a suitable gap. The gap is too large, the heating efficiency is very low, and it is not even hot.

Fourth, the appropriate operating frequency, the thicker the billet, the lower the frequency. The finer the billet, the higher the frequency.
