Thermal Imaging Applications in Parts Quenching Processing Monitoring

The hollow-pipe quenching machine uses high-frequency currents to heat up and cool down the surface of the workpiece. In this way, heat treatment is implemented for the surface-hardened layer, and the center’s temperatures and the workpiece’s bend are monitored. Whether the monitored temperatures satisfy certain standards is the basis for determining whether the workpiece is qualified. A certain difference exists between the temperatures at the center and the bend of a workpiece. The workpiece is regarded as qualified when specific values are reached. When a workpiece is heated by high-frequency currents, the workpiece will be scrapped with a loss generated if the highest processing temperature is reached.
