1. Induction heating is directly heated by the internal heat source, and the heat loss is small, so the heating speed is fast and the heat efficiency is high.

    2. During the heating process, due to the short heating time, the surface of the part is less oxidized and decarburized, and the scrap rate of parts is extremely low compared with the conventional flame .

    3. After induction heating and quenching, the surface hardness of the parts is high, the core maintains good plasticity and toughness, and the low notch, fatigue strength and wear resistance are greatly improved.

    4 , induction heating equipment is compact, small footprint, easy to use ( ie easy to operate ) .

    5 , the production process is clean, no high temperature, good working conditions.

    6 , can be selectively heated.

    7. Induction and heating surface quenching mechanical parts are less brittle and can also improve the mechanical properties of the parts. The quenching hardness of steel parts that have been subjected to induction heating and surface hardening is also higher than the quenching hardness of conventional flame heating .

    8 , the induction heating device can be placed in the processing line, the electrical parameters of the process through the intake line precise process control.

    9. By induction heating and quenching, ordinary carbon structural steel can be used instead of alloy structural steel to make parts without reducing the quality of parts. Therefore, under certain conditions, it can replace the complicated chemical heat treatment.

    10. Induction heating is not only applied to the surface quenching of parts, but also to the inner hole quenching of parts, which cannot be achieved by flame heating .
