Abstract

Installation for the control of tension across the width of strip during the rolling of metals comprises at least three thickness measuring devices, each spread over the strip width at both the inlet and outlet sides of the roll stand. These are connected with tension profile controlling computer and programming devices, which feed via suitable relays an electrical setting device and a hydraulic pump, which actuates a cylinder for adjusting the degree of crown of the rolls. The devices ensures even thickness across the strip being rolled, and may be used both for ferrous and non ferrous rolling mills.
