Overview: Applicable steel rod surface quenching, quenching depth of 10mm. The power supply is a set of 6-pulse KGPS100KW/1.5KHZ intermediate frequency power supply.
Working process: first set the quenching temperature on the temperature control instrument, then put the workpiece into the guiding trough, press the running button, the pneumatic feeding mechanism pushes the workpiece into the inductor to heat, and the far infrared thermometer detects the workpiece. Heating temperature, when the temperature reaches the set temperature, the device automatically stops, the workpiece is sent out of the sensor, and a heating process is completed. Put another workpiece and press the RUN button again to proceed to the next heating process.

3 power frequency and calculation heating beat
3.1 power frequency
According to the half-axis external dimensions, it is especially important to select the appropriate frequency considering the temperature difference of the core. The theoretical calculation combined with the actual experience, the quenching depth is 10mm, and the power frequency is 1.5KHz.
3.2 Calculating the heating beat
After quenching depth of 10mm, quenching capacity: 100mm/5s, 100KW intermediate frequency power supply can meet the requirements.
IF quenching device sensor description
The inductor includes an induction coil, a bus bar, a fixed bracket, a shower system, and the like.
1 induction coil
The induction coil is made of 99.99% T2 rectangular copper tube. The outer insulation of the induction coil is sprayed with a high-strength epoxy insulating resin by electrostatic spraying. The insulation layer has a withstand voltage greater than 5000V. The inductor coil comes with a spray quenching liquid hole.
2 induction coil parameters
The parameters of the induction coil are optimized with specialized computer software. It can guarantee the best electromagnetic coupling efficiency with the quenching transformer under the same capacity.

Medium frequency quenching equipment quenching transformer
The quenching transformer adopts WISCO cold-rolled oriented silicon steel sheet, the coil is wrapped with asphalt mica tape and heated to dipped in the baking process, which makes the transformer with higher withstand voltage and better waterproof. Transformer water collection
All the stainless steel materials (including the hose clamps of the water pipes) are used, which reduces the unnecessary damage caused by the transformer damage caused by the water interception of the water collector.
