Abstract (en)
[origin: DE19539408A1] The disclosure concerns a calibre contour in the substantially circular rollers of a reduction roller mill with three-high stands, intended in particular for use in rolling thick-walled tubes with wall thickness/diameter ratio which is greater than 0.25. The calibre contour of each roller (1) has a widening in the diameter (5) in the region of the contour floor in which the region of rolled material rolled to an upstream (in the direction of the roll) calibre can be deformed.
