Heat treatment is performed by placing the heat treatment jig with the wound metal wire in a heat treatment furnace.

The heat treatment process comprises pre-heat treatment and quenching-and-tempering heat treatment.

The laser oscillator outputs the thermal processing laser beams for thermal processing, and outputs surface processing laser beams for pre-processing or post-processing of the thermal processing.

After the thermal treatment, the region where the thermal treatment is performed is irradiated with a laser beam with less power than that for the thermal treatment.

In particular, the heat treatment takes place by means of electrical resistance heating (Faraday's heat treatment).

Heat treatment 2: The package after the heat treatment 1 is introduced into an atmosphere at 240°C.

The heat treatment can be applied to incineration treatment in the tail cylinder (1), as well as to all products necessary for heat treatment.

Thermal shrinkage (ppm) = {amount of shrinkage of glass before and after heat treatment/length of glass before heat treatment} × 106

The manufacturer must submit the procedure for the heat treatment used.

Addition of N-acetyl cysteine after heat treatment and optionally before heat treatment maintains a low level of met-hemoglobin.
