Recently the importance of the length measurement of rolled materials has been increasing. Automatic length measuring equipments are expected to contribute not only to the improvement of operational facilities but also to the optimization of the cutting of materials and the saving of labor.
About the measuring equipments of the length of rolled materials, many reports have been issued in these several years, but few of them are operating well.
This report describes two kinds of automatic length measuring equipments that have been installed in the wide flange beam mill, Fukuyama Works, Nippon Kokan K.K. One of them is installed at the delibery of the finishing mill, and the other at the delibery of the roller straightener. The accuracies of the equipments are within ±200mm and ±20mm, respectively.
