4-High Rolling Mills. Four-high rolling mills can be put in tandem, two to seven stands, instead of a reversing mill. They can be equipped with load cells to tell the separating force and hydraulic or mechanical screw downs, depending if it is hot or cold rolling. Sometimes mechanical screw downs are preferred when there is a risk of fire.
Single-stand reversing cold mills. Depending on the product mix, a single-stand cold rolling mill can deliver rolling capacities of 100,000 to 400,000 t/a. Rolling schedules can be carried out with an even or odd number of passes to maximize mill availability and performance. Sundwig S6-high cold rolling mill - ANDRITZThe patented Sundwig S6-high side support stabilizes the work rolls in this type of mill stand using mechanical, hydraulic lateral support equipment, thus preventing lateral excursion of these rolls. The diameter of the S6-high work rolls is only approximately 30% of the diameter of the 4-high work rolls and double the diameter of those work rolls usually found in a 20-high rolling mill for comparable strip
