Apart from induction heating, cooling is an indispensable procedure of heat treatment technology. Cooling methods which are used to control cooling velocity are different due to the difference of cooling processes. Water cooling system is commonly used in heat treatment process. Generally speaking, the cooling velocity of induction annealing is the slowest, that of induction normalizing is fast, and that of induction hardening is the fastest. However, there are different requirements for different steel materials, for example, hollow hard steel can be hardened at the cooling velocity of normalizing.

Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, through heat generated in the object by eddy currents. An induction heater consists of induction power supply (induction heater) and inductor (coil) that is a shaped to contour the part, and a work station where the part is held and presented to the coil.
