Improvement of thickness tolerances For a two-stand aluminium cold rolling mill

trol loops to compensate backup roll eccentricity and harmonic hardness variation allows a significant improvement in strip thickness performance. These measures were successfully implemented as an extension to an exist ing two-stand aluminium cold rolling mill. An essential quality characteristic in the cold rolling sector is the minimum thickness deviation that can be achieved at final gauge,...

A Robust Dispersion Control Chart Based on M-estimate

Process control charts are proven techniques for improving quality. Specifying the control limits is the most important step in designing a control chart. The presence of outliers may extremely affect the estimates of parameters using classical methods. Robust estimators which are not affected by outliers or the small departures from the model assumptions are applied in this paper to specify th...
