キャンプツールの焼入れと点火プロセス

1. 運動とは、鋼を特定の温度に加熱した後の鋼の急速な冷却を指します, その組織構造が変化するように, thereby improving the hardness and strength. The temperature of quenching is different from the cooling medium, which will have a different impact on the performance of steel. 一般的, 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, その組織構造が変化するように, 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. 一般的, 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.
