  Steel Rolling

  The backing roll diameter cannot be greater than about 23 times that of the work rolls, and as the work roll diameter is decreased more and more (to accommodate processes with exceedingly high rolling loads) the size of the backing rolls must also decrease. A point is reached when the backing rolls themselves begin to bend and must be supported hence the ultimate design the cluster mill ...

  Aluminium rolling models: work roll camber

  The rolls in the mill are going to bend and deflect under load. The additional deformation will tend to over roll the edges of the material. This will make the material looser and create edge waves. We will need to compensate for the additional deformation by using a positive bend or by grinding a different camber on the rolls. We''ll now consider the latter of these two options.

The first experiments at rolling iron for tinplate took place about 1670. In 1697, Major John Hanbury erected a mill at Pontypool to roll ...
