Based on the latest universal rolling technology, it is made up of 15 SHS housingless stands in 2-high horizontal or universal arrangement equipped with automatic quick program changing system. All universal stands can be quickly re-assembled as 2-high stands, to adjust the mill to the roll pass schedule depending on the product being rolled.

Rolling schedules can be carried out with an even or odd number of passes to maximize mill availability and performance. The Universal Crown Control mill (UCM mill) with work roll bending, intermediate roll bending, intermediate roll shifting and all straight roll application ensure enhanced flatness control.
