By default, the strip width in a hot-strip mill is deter-mined by edging and rolling the strip in the roughing mill. The width deviation after the finishing mill arises from the width deviation in front of the finishing mill and from width-spread anomaly occurring inside the finish-ing mill. The behavior of width spread in a finishing mill

Cold Rolling - Automated Monitoring and Targeting System. A system installed at the UK based strip mill reduced energy demand of the cold rolling mill by approximately 15-20% (Worrell et al., 2010. p. 104) or approximately by 0.22 GJ/t-product (US EPA, 2010. p. 30). Emission reductions are estimated to be 35.3 kg CO 2 /t-product.
