Optimal Width Reductions in Hot-strip Mills

抄録

Investigations have been carried out to optimize the pass-schedules of the rougher in hot-strip mills. The aim was to increase the yield and reduce the number of necessary slab widths. In this paper results from industrial trials using varying edging schedules are presented. The working range for early as well as late edging is discussed. Pilot plant trials on hot steel at MEFOS show that by varying the roll gap during rolling, a strip with uniform width and small crop losses can be produced.
