Abstract (en)
[origin: EP2277637A1] A six-high rolling mill includes paired upper and lower work rolls (2) for rolling a strip (1) , paired upper and lower intermediate rolls (3) for supporting the paired upper and lower work rolls, and paired upper and lower back-up rolls (4) for supporting the paired upper and lower intermediate rolls, the six-high rolling mill having no supporting rolls inside and outside the reliable strip width of the work rolls. A similar four-high rolling mill lacks the intermediate rolls. In the six- or four-high rolling mill, the work rolls are driven, and the work rolls have a small diameter, and use a material having a high modulus of longitudinal elasticity, such as a cemented carbide or a ceramic.
