AB Materials Technology Fredrik Sandberg Title Design and function of CVC rolls as a flatness actuator in a cold rolling mill Keywords Flatness, actuators, CVC, cluster mill, cold rolling, strip Summary When cold rolling thin steel strips with high tensile strength, reversible cluster mills are used.
Rolling is the most important metal forming process. More than 95% of ferrous and non-ferrous metals and alloys are processed to their usable shapes by rolling. Usable shapes of rolled metals are plate, sheet, strip, foil, different sections like rail, beam, channel, angle, bar, rod, and seamless pipe, etc., as shown in Fig. 1.1 and Fig. 1.2.

A new technology for measuring the thickness of non-ferrous metals strips has been developed by ABB. It is based on pulsed magnetic fields,and therefore features a unique combination, i.e. the measurement is contact free and measuring results are independent of material properties. Tests in a copper rolling mill have shown the
