What is induction heating? What is the purpose of induction heating?
Heating martensitic steel to the critical temperature to hold the heat, and then cooling to adjust and improve performance is called induction heating. Sometimes the process of normalizing large castings and forgings is also referred to as induction heating china.
To reduce brittleness, eliminate or reduce internal stress;
To achieve the required mechanical properties of the workpiece;
To stabilize the dimensions of the workpiece;
Annealing is used to soften some hard alloy steels, and high-temperature tempering is often used after quenching (or normalizing) to allow the carbides in the steel to aggregate appropriately, thereby reducing hardness and making it easier for machining. On the other hand, it can also reduce the cooling stress in large castings and forgings.
