  • Control Of Metal Rolling (AREA)

Abstract

PURPOSE: To control automatically and accurately the thickness and the shape of cross section of the rolled material, by measuring actually the length of the material entering into the rolling mill and, corresponding to this, the length of the material coming out from the rolling mill and by controlling the extension while estimating the whole length of the finished material on the basis of the measured length.
