Do not ignore the preparations before high frequency quenching operation

Do not ignore the preparations before high frequency quenching operation:

1. Clean the oil and other dirt on the workpiece to prevent smoke from being generated during heating.

2. Remove iron filings and burrs to prevent arcing and burn sensors and workpieces.

3. Check the workpiece for cracks.

4. Select the equipment and quenching method, and select the frequency and power of the induction quenching equipment according to the depth of the hardened layer and the quenching position required by the process card or workpiece, so as to determine the equipment used.

5. Select the inductor according to the quenching position and quenching method of the process card or workpiece.

6. Clamp the workpiece and the sensor, pass water to the sensor, and adjust the water pressure to an appropriate pressure. Start the quenching machine, rotate the workpiece, and observe whether the gap between the workpiece and the inductor is uniform, and whether the relative axial position is appropriate.
