2 Apr 2015, Abstract: In the thin sheet cold rolling manufacturing process, a major issue is roll elastic deformation and, Figure 6 shows the flow chart of the global numerical scheme Some points, limited to 4-high or 6-high mills, when all roll centerlines are in a …
finishing mills, which will roll the steel in tandem with one another. The workhorse roughing mill has 135" wide rolls for rolling 'broadside' (as the first roughing mill is commonly called) to make a slab wider. A 5,000 hp motor drives 42"-diameter work-rolls through 28:1 …
John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014. 3.5 Friction and Wear. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Back-up rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill).
