The importance of induction coil when choosing high-frequency hardening equipment

When everyone buys high-frequency hardening equipment, most people only pay attention to the equipment itself, but ignore the inductance of the equipment’s induction coil. In fact, the inductance of the induction coil is closely related to the frequency of the high-frequency hardening equipment.

When the high-frequency hardening equipment heats the workpiece, it must work through the induction coil, so the production skills of the inductor can sometimes directly affect the effect and quality of the workpiece heating process.

The induction coil is closely related to the inductance and frequency. The main factors that affect the induction coil are the number of coils, the number of parallels, the length, the diameter of the induction coil, the diameter of the copper tube, the pitch of the turns, the number of copper tubes, etc., so buy high Frequency hardening equipment should also pay attention to the inductance of the induction coil.

Generally speaking: the more turns, the greater the inductance, and the lower the frequency; otherwise, the higher; the longer the length, the greater the inductance, and the lower the frequency; otherwise, the higher;

The larger the diameter, the greater the inductance and the lower the frequency; otherwise, the higher; the more the number of parallels, the smaller the inductance and the higher the frequency; otherwise, the lower;

The larger the turn spacing, the smaller the inductance and the higher the frequency, and vice versa; the larger the diameter of the copper tube, the smaller the inductance and the higher the frequency, and vice versa;

The more the number of copper tubes, the smaller the inductance and the higher the frequency, and vice versa.
