Objective
As rolling process costs are a significant part of the price of mild and high- carbon steel strips, the increase of reduction on the first stands of a tandem mill is an interesting way to increase productivity. This can lead to an improved productivity of the hot strip mill by providing thicker strips at the entry, while keeping the same final gauge. Furthermore, keeping the same entry gauge can lead to thinner and harder products. However, reduction is, so far, limited by the onset of strip defects (heat streaks or shape problems) or by technological problems (stand power problems, guiding problems). The goals of the project are: to explore new ways of increasing reduction while keeping the quality of the strips; to develop understanding of the defects and the problems arising in order to push further the limits of high reduction safe rolling; to assess the best performance available without increase in investments; to reach on the first two stands a 5% extra-reduction compared to actual reductions.
