The hardening case depth and hardness curve can be changed by adjusting heating time, heating power and cooling speed during induction hardening.
在感应淬火中，通过改变加热时间、加热功率和冷却速度可以改变淬硬层深度和硬度梯度。
2
CONTROLLED COOLING: Process by which steel is cooled from an elevated temperature in a predetermined manner to avoid excessive hardening, cracking or internal damage.
强制冷却：将高温钢材强制冷却到设计温度的工序，可防止钢材硬化过度，破裂或者内部损伤。
