Abstract: A new rolling mill configuration is provided containing fourteen rolls and which may be described as an improved six-high arrangement. The mill contains two substantially identical upper and lower roll clusters. Each roll cluster comprises a floating work roll, a chock mounted intermediate roll and a chock mounted back-up roll. The work roll is supported laterally by a pair of chock mounted side intermediate rolls and each side intermediate roll is supported by a single side backing roller assembly. The chocks of each side intermediate roll and the adjacent side backing roller assembly are supported by an adjustable stationary rigid support beam assembly.
Abstract: A new rolling mill configuration providing improved performance and lower cost than is possible for conventional four-high and six-high mills.This mill configuration contains eighteen rolls and may be described as an improved six-high arrangement, the improvement being in the provision of side support assemblies for the work rolls, thus enabling smaller work roll diameters to be adopted than is possible with four-high or six-high mills, resulting in lower separating forces and thus a lighter and less expensive mill construction for a given duty.
Abstract: A cluster type rolling mill intended to provide work roll sizes in the range between the small sizes available with current cluster mill designs and the large sizes available with current four-high mill designs is disclosed.This mill combines the advantages of existing cluster mills (heavier reductions per pass and between anneals) with the advantages of four-high mills (easier to maintain thermal equilibrium of work roll giving ability to roll at higher speeds).
Abstract: In a cluster mill having independently adjustable eccentrics on each saddle on at least one backing shaft to adjust the roll gap in line with each saddle, means to adjust the eccentrics in synchronism to produce a tapered roll gap and separate means to adjust the eccentrics in synchronism to produce a crowned roll gap, and, in combination, means to produce a roll gap with a composite crowned and tapered form.
Abstract: In a cluster mill having individual crown adjustment drives to each saddle on at least one backing shaft to adjust the roll gap in line with each saddle, means to synchronize the drives mechanically to produce a tapered roll gap so that strip having a transverse taper in thickness can be rolled. Also means to control automatically the operation of the synchronized drives in response to the behavior of the rolled strip. Also means to synchronize the drives mechanically to produce a roll gap having a parabolic profile or any required profile to suit the incoming strip or to compensate for the crown of the mill itself.
