STRIP HEADS IMPROVED DURING CONTINUOUS HOT ROLLING
This report describes the work carried out to improve the shape of strip heads in the continuous plate rolling mill at the Forges de Clabecq. The first section deals with the problem of bending in the extreme head. Various experiments revealed the origin of such faults, which arose predominantly in the first stand. Improving the symmetry of rolling in this stand produces a considerable improvement in results. The second section describes the strategy of taking advantage of roll bending in the four stands to achieve better presetting of the mill. A natural consequence of this investigation is the implementation of a control function, the CAC (Controle Automatique de Cambrage), which counters any variation in the rolling force by a corresponding variation in the bending force, so as to retain a constant sheet profile.
