The PCFC® system (Profile, Contour and Flatness Control) calculates the correct shifting position of the specially ground work rolls and the setup values for work roll bending, resulting in the ideal roll gap for each strip rolled. By taking into account the varying rolling conditions, narrowest geometrical tolerances are guaranteed, providing for efficient further processing of the hot strip in the downstream coupled pickling line and tandem cold mill and in the strip processing lines.
Before the final acceptance the required dimension range of strip thicknesses between 1.2 and 25.4 millimeters and strip widths of up to 1,900 millimeters had been successfully rolled. The grades rolled included steels for the automotive industry, for construction applications as well as X80 pipe grades. Thanks to the proven profile, contour and flatness control (PCFC®) system and the sophisticated CVC®plus actuators, the geometric target values specified for the thickness profile and the strip flatness were safely achieved.
The customer Shandong Iron & Steel Rizhao commented very positively on the trouble-free commissioning of the high-performance hot strip mill: “With the plant engineering and process technology from SMS group we can now produce hot wide strip as primary material for the automotive and pipe manufacturing industries in a highly efficient way.”
