1. Rapid heating speed allows workpieces to reach the required temperature in a very short time, even within one second. Therefore, surface oxidation and decarburization are relatively mild, and most workpieces do not require gas protection.
2. Workpieces treated with induction heating have a thicker hard layer on the lower surface and good internal compressive stress in the tough areas, resulting in higher fatigue and fracture resistance.
3. The heating equipment is easy to install on production lines, readily mechanized and automated, easy to manage, effectively reducing transportation, and improving production efficiency.
4. Easy to use and simple to operate; can be started or stopped at any time, and requires no preheating.
