European tandem mills were mostly built at least 30 years ago, when rather soft steel grades were cold rolled. Consequently, their technological capacity limit, notably the maximum rolling force, can easily be reached in the production of today's harder and thinner strips. This rolling force, which is the vertical force exerted by the rolls on ...
