Heat treatment flame quenching

In the process of flame quenching, the flame is directly applied to the metal to harden the metal surface without affecting the base material. To control the case hardening level so as not to affect the whole metal part, temperature monitoring is very important.

The traditional contact temperature measuring instrument measures the temperature of the flame, not the temperature of the component itself, so it is necessary to use non-contact method to measure. By using a wavelength of 3.9 μ m, a pyrometer or imager can measure the surface temperature of the metal through a flame.

The measurement solution uses a specific band to measure the true surface temperature of the metal through the flame. In this way, precise quality control can be achieved to ensure the correct surface hardening without affecting the internal characteristics of metal parts.
