Abstract (en)
[origin: EP0665067A1] The column type multi-roll stand comprises a roll set (2) above the rolling gap and a corresponding roll set (3) below this gap, and is preferably provided with a direct hydraulic setting system. Two roll sets with a larger number of rolls enclosing respectively working rolls (5) and (5') with a relatively smaller diameter can be replaced with two roll sets with a smaller number of rolls enclosing working rolls with a relatively larger diameter, and vice versa. In both cases each roll set (2,3) has a number of rolls which remain without changes. Working change allows a 20-roll stand to be converted into a 14-roll stand. In this case the rolls (5,6,7,8) in the roll set (2) and the rolls (5',6',7',8') in the roll set (3) are replaced by a single larger-diameter roll in each roll set.
