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 ...

lubricant is applied during cold rolling to act as a coolant, to prevent surface damage and to reduce friction. Nevertheless the deformation of surfaces under unlubricated conditions provides a useful starting point for lubricated rolling, and points up the key features in the mechanics of asperity deformation. 4.2.1 Without bulk deformation

The result is a 'feasible' rather than 'optimum feasible' mill design. This work applies nonlinear programming to optimize the basic design of a 4-high reversing cold rolling mill, subject to static strength, fatigue, and strip geometric quality constraints.

Cold rolling on a 4 hi reversible mill 1. A brief on Cold Rolling of Steel in a 4 Hi Mill By Hussam Adeni Lubricant Specialist 2. Cold rolling of Steel strips The raw material for Cold rolling is typically a Hot rolled coil (HRC). At the CR Mill it undergoes the following operations: 1.

The most common configuration is the single reversing mill. Various mill designs are offered that include 6-high UCMs (Universal Crown Control Mill), ZR mills and 12-high cold-rolling mills with small-diameter work rolls for the efficient rolling of materials of high hardness.

The cold mill pilgering process uses ring dies and a tapered mandrel to reduce tube cross sections by up to 90 percent. Because the process relies on large number of small forming steps, the result is tube or pipe that has nearly homogenous material characteristics. It is suitable for every metal.
