Good figures for rod and bar mills are 90 % to 93 %, for structural mills, the good mill utilization figures are 75 % to 78 %. If a mill rolls 80 % of the calendar year, that is 365 x 24 x 0.80 = 7008 hours. If the mill rolls 800,000 tons per year, it runs at an average production rate of 114.16 tons/hour.

• Rolling speeds: up to 25m/s for CR. • 2-high or 3-high mills are used for HR in initial breakdown passes on cast ingots or in continuous casting, with roll diam range from 0.6m to 1.4m. • 4-high mills and cluster mills are based on the principle that small diameter rolls lower roll forces & power req. and reduce spreading.

Using the working diameter of the rolls, the roll rpm (revolutions per minute) is matched to the bar speed through the mill. As the rolls wear and the spread of the bar in the pass changes, the rpm of the stands need to be adjusted as the bar area changes. Most modern control systems modify the R-Factor as this occurs.
