Roll camber control in strip rolling mills - with computer operated checking and rectification

摘要

Roll camber in a strip rolling mill is checked and rectified by plotting actual camber at any time, and comparing it with a reference camber, pref. that of the roll when new. Checking is carried out along a horizontal plane through the axis of the roll, with the mill running, at intervals depending upon the rolling programme. When differences between measured and reference profiles exceed a predetermined amount rectification is carried out automatically, e.g. by grinding, pref. computer controlled. Both operations are pref. carried out by a single combined unit.
