New on-line gage for edge drop measurement and effect of tapered work rolls

摘要

Because of the edge drop effect in cold rolling and despite major improvements in the operation of hot strip mills the control of the strip profile is a significant aim for operators in cold rolling mills. Greater knowledge and control of transverse thickness leads to research in two directions: the study of the efficiency of control device actuators; and making available profile thickness gages that achieve good performance. IRSID and Sollac have, therefore, been evaluating the efficiency of tapered work rolls on tinplate mills, by trials on a pilot mill and commercial mill. Concurrently, they have developed a new generation of edge drop measurement gages.
