The 2.5 D technique was applied to the roll pass de-sign problem. The simulation results were used for ad-justing roll gaps to achieve the required bar shape and the uniform distribution of rolling force between the passes. Two roll pass designs were developed and analyzed: a classical oval-round roll pass design and a combination

Flat rolling of plates and sheets is essentially a plain-strain compression. f1.2. Roll Pass design for steel The cross sectional area is reduced in each pass and the form and size of the stock gradually approach the desired profile. Here the thickness of the metal being rolled is reduced in each pass by decreasing the distance between the rolls.

Figure 2 shows grooved rolls for a new type of high-lift stands introduced to increase drafts at secondary mills compensating for the absence of blooming-slabbing mills. Roll costs contribute about 5 - 15 % of overall production costs, estimated at about US$ 1-5 per ton of rolled product and per rolling mill stand.

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. 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.
