Development of New Camber Gauge to Measure True Bar Shape in Hot Strip Mill

In hot strip mills, camber is an important quality characteristic of a transfer bar coming out of a roughing mill. Excessive camber negatively impacts subsequent process in a finishing mill. Therefore, it is desirable to measure and control the bar camber during rolling in a roughing mill. Centerline deviation measurements cannot distinguish bar movements from bar shape changes. A new camber gauge system for roughing mills allows for characterization of the true bar shape, providing camber/curvature information that can potentially be used by operator/control system to correct the bar shape. Camber sensing and its current application are described.
