Streching and Tension Levelling Lines
Stresses raised in cold work practice may result in problems for certain metal processes. In these cases a further operation must be done: this is why more than 40 years ago Danieli FATA Hunter built its first aluminium stretching and tension levelling line.
The coil, coming from rolling, is processed in a tension levelling machine and is ready for final treatments.
Various line configurations (stretching only, roll levelling, combined stretching and tension levelling) have been developed and applied since then to meet modern industrial requirements.
