Normalizing
It consists of heating the steel to a temperature above the critical zone (723°C), followed by air cooling. The purpose of this Heat Treatment is to refine the coarse grain of cast, rolled or forging steel parts.
Normalizing is still used as a preliminary treatment to quenching and tempering, mainly to produce a more uniform structure than that obtained in rolling, for example. In addition, it also helps to reduce the tendency to warp and facilitates the solution of carbides and alloying elements.
Grefortec also manufactures furnaces for Normalizing , such as:
