Part 1 Geometry of flat-rolled products: definitions of geometrical parameters; standardization and quality requirements; standard dimensional tolerances; statistical and analytical dimensional tolerances. Part 2 Principles of measurement: definitons of basic metrological terms; transducers and sensors; principles of signal treatment. Part 3 Gauge control in rolling mills: causes of gauge variation; automatic gauge control systems; dynamic characteristics of roll gap control systems; causes and effects of roll eccentricity; methods of roll eccentricity compensation. Part 4 Width control in rolling: theory of width change; methods of width change by casting and rolling; methods of width change by pressing; optimization of the width change process; automatic width and plan view control systems. Part 5 Theory of strip profile and flatness: effect of roll deformation on strip profile; effect of roll thermal expansion and wear on strip profile; strip profile and flatness analysis; roll bending analysis. Part 6 Strip profile and flatness control: roll bending systems; roll shifting and cross systems; rolls with specific profiles; flexible edge rolls; strip profile and flatness sensors; automatic strip profile and flatness control systems.
