ANNEALING LINE

In this plant, steel sheet that has changed physical features after process of Cold Rolling, described as full-hard (hard and fragile), exposed in a thermal treatment in accordance with annealing recipes to obtain desired quality features.

Coils are annealed with the heat that generated from natural gas in a pure hydrogen gas atmosphere. Annealing process, eliminate the internal strain on steel sheet that generated during cold rolling and provide re-crystallization. Annealing takes time approximately for
50 hours and approximately 100 ton can be annealed in each base of annealing furnace during this period.
