Straightened bars warehouse

The straightened and checked bars are picked from the warehouse and prepared for peeling.

Induction heating

Heating occurs through induction by raising the bar's temperature to 700–750° C.

Water cooling

Water cooling crystallises the structure and increases its hardness.

Tempering

Tempering occurs through a second induction heating process at lower temperatures, around 500° C.

Plate cooling

Plate cooling is slower but improves the steel's tenacity value.

Quenched bars warehouse

The quenched bars are strapped and stored in the warehouse ready for being shipped.
