Abstract

A method and an arrangement for controlling the thicknesses of webs and flanges of beam sections in universal rolling mill stands.

In order to maintain a certain ratio of web elongation to flange elongation, the gage-meter circuits are coupled to each other for a mutual influencing. The adjustment can be effected in dependence on a rolling schedule.
