Abstract

A device for detecting and correcting errors in the flatness of steel strip as it passes through the rolling mill consists of a roller which is located above the strip surface after the rolls. It has two parts, an outer mobile part which rotates as the strip passes over it and is formed of several sections coupled together, and an inner immobile part containing the detection apparatus. The detection devices consist of a number of jacks filled with fluid connected two to each section and to visual display of pressure change. As the strip passes over the roller, changes in pressure are registered as pressure changes in the fluid in the jacks.
