El proceso de enfriamiento y encendido de la herramienta de camping

1. El ejercicio se refiere al enfriamiento rápido del acero después de calentar el acero a una cierta temperatura., para que su estructura tisular cambie, mejorando así la dureza y la resistencia. La temperatura de enfriamiento es diferente a la del medio de enfriamiento, which will have a different impact on the performance of steel. En términos generales, the quenching temperature of the carbon steel outdoor tool is about 1000 ° C. The cooling medium can choose water, oil or air. Water cooling speed is the fastest, but it is easy to produce deformation and cracks: the oil cooling speed is moderate, but it is easy to produce sparks and smoke: the air cooling speed is the slowest, but it is not easy to produce deformation and cracks.

Recking process

2. Reflection refers to cooling the quenching steel to cool down after a certain temperature, para que su estructura tisular cambie, thereby reducing the hardness and strength, and improving toughness and plasticity. The temperature and time of recovery will have a different impact on the performance of steel. En términos generales, the recovery temperature of the carbon steel outdoor tool is about 200 ° C, and the time is about 1 hour. Excessive fire temperature and time will cause steel to soften, and too low will cause steel to become crispy.
