ROLLING MILL AND TANDEM ROLLING MILL HAVING THE SAME

摘要

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 Tollable 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 tolls have a small diameter, and use a material having a high modulus of longitudinal elasticity, such as a cemented carbide or a ceramic.
