Installed in Eregly in Turkey and linked to an existing continuous pickling line, the new tandem mill of Tatmetal Çelik is in full operation. The mill consists of five, 6-high mill stands with 22,000-kN separating force to roll quality high-strength strip from 0.2 to 3.0 mm thick, up to 1550-mm wide, with superior flatness correction capabilities for 1.2 million tonnes per year of cold rolled strip. The operational flexibility is ensured thanks to the installation of positive/negative work-roll and intermediate roll bending, and intermediate roll-shifting systems on each stand, with the possibility of using tapered or shaped rolls. Additionally, final strip shape is controlled by an in-line shapemeter providing feedback on bending, tilting and selective cooling headers on mill stand # 5.

Ultra-low hysteresis HAGC with a 45% faster response time ensures precise control of strip thickness. As a result, strip thickness tolerance decreases down to +/- 0.6%, head/tail off-gauge length are lower than four meters, and strip flatness less than 6IU.

Sealing the exit strip gap at rolling mill exit stand, Danieli-patented Confined Jet Dryer effectively removes any droplets from the strip surface, guaranteeing high-quality strip surface appearance.

All electrical equipment and control systems providing an integrated and optimized system configuration have been supplied by Danieli Automation.
