It is a correct choice to use medium-frequency external inductor water spray cooling and quenching process for products such as inner ring gears

Development and application of medium frequency external inductor

1. The inner ring gear and other products adopt the medium-frequency external inductor water spray cooling quenching process, which is the right choice, and the quenching quality is stable and reliable.

2. The developed medium frequency external sensor and water spray cooling device have correct design and reasonable structure.

3. Reasonable selection of heat treatment process parameters. After heat treatment, the hardness of the workpiece can meet the technical requirements.

4. Products such as inner ring gears are quenched with medium frequency external inductors to avoid the defects of high production cost, long production cycle and poor quality of flame quenching.

5. The application of medium-frequency external sensor technology has greatly improved product quality and work efficiency, and has significant social and economic benefits.
