Werner W Eibe: Closed loop integrated gauge and crown control for rolling mills. Blaw Knox Foundry & Mill Machinery, Buell Blenko & Ziesenheim, October 18, …
With noncontact thickness measurement at the exit of the tube mill, a closed-loop control can automatically adjust entry strip thickness. After being set by the operator, the self-correcting thickness control adjusts for both variation in strip thickness and hardness.
Electro-hydraulic closed-loop servo positioning was used for all the cylinders, with improved operator displays of crown and intermediate-roll settings. In 1990, it …

Abstract. Automatic rolling process is a high-speed system which always requires high-speed control and communication capabilities. Meanwhile, it is also a typical complex electromechanical system; distributed control has become the mainstream of computer control system for rolling mill.
Closed-loop control of strip flatness using any combination of coolant sprays, mill tilt, roll bending and variable crown rolls, plus Edge Calcoil which assists with edge flatness control.
ASC mainly includes edge drop control, crown control and flatness control in tandem cold rolling mills, PCFC (profile, contour and flatness control) with wear control ability in hot strip mills nowadays suggested by Cao et al., 2010, Cao et al., 2011 and Abdulrahman et al. (2013).
Stands of finishing mills : Automatic gauge control (AGC), Continuous variable crown (CVC) – axial shifting, positive / negative bending of intermediate and work rolls. Servocontrols Servovalves, Temposinics (position sensors), Heavy Duty Pressure Sensors, Servo Actuators and Manifold Block Systems & Electronic Controllers are used in these closed loop aplications. Cold rolling mill for …
System Description. The TelePro/SSE AFC system consists of integrated control of work roll bending, HGC tilting, variable roll crown shifting (if available) and multi-zone work roll cooling to minimize deviations between target and measured exit strip stress distributions.

In rolling mill, the accuracy and quality of the strip exit thickness are very important factors. To realize high accuracy in the strip exit thickness, the Automatic Gauge Control (AGC) system is used. Because of roll eccentricity in backup rolls, the exit thickness deviates periodically. In this paper, we design PI controller in outer loop for ...
