Measure True Bar Shape in a Hot Strip Mill with a Camber Gauge

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 gage 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.

The camber gage can be configured for either of two different types of applications:

• Strip Steering and
• True Bar Shape measurement.
