If the mill rolls 800,000 tons per year, it runs at an average production rate of 114.16 tons/hour. If the utilization can be improved by 1 %, the available rolling hours is 365 x 24 x 0.81 = 7096.6, creating 87.6 extra rolling hours. At 114.16 tons/hour that is an additional 10,000 tons can be rolled.

TYPES OF "TRAP" ROLLS: 7.0 ROLL DESIGN TIPS When forming a bend that has a 1t or less inside radius and when "box" forming, a "coining" or "bead" pass is very effective in setting the corner. By coining the material a slight thinning will occur. However, the finished bend corner will be crisp. FIG #8: COINING PASS.
