Nov 23, 1988 Rolling mills are increasingly demanding rolls capable to maintain the shape and profile much longer with the aim to extend the length of campaigns. The state of the surface is one of the criteria determining the roll change. With the aim to satisfy the mill requirements it
These backup rolls are larger and contact the back side of the smaller rolls. A four-high mill has four rolls, two small and two large. A cluster mill has more than 4 rolls, usually in three tiers. These types of mills are commonly used to hot roll wide plates, most cold rolling applications, and to roll foils.
Cold Rolled Product: Cold rolled product is made from the hot-rolled product. When the hot-rolled product is cooled, then that is re-rolled in the room temperature. It is known as Cold Rolled Product. It is used to do to get more exact or perfect dimensions and to make the surface quality better. There are such Cold rolled products.
In both the top and bottom pinch rolls, the sleeve is a horizontally, centrifugally cast, thick-walled piece with a specific Bemcalloy™ chemistry that has been tailored to meet the specific needs of the application. The Bemcalloy™ C-141 material is the most established of Xtek’s pinch roll
Kubota's Rolling Mill Rolls Support the World Steel Industry. In 1961, Kubota became the first company in the world to adopt the "centrifugal casting" method for the production of mill rolls. It enables to produce a multi -layer composite rolls , which revolutionized mill roll material .
The middle of roll becomes hotter than its ends and hence roll diameter in the middle of roll increases. In hot rolling mills this effect is quite pronounced and should be taken into account while calculating the roll camber. In cold rolling mills the coolant supply at different points on roll surface may be adjusted to minimize this effect.
20 High Cluster Mills utilize small diameter work rolls which allow higher reductions on harder materials than other mill configurations. The multi-roll system having employs a unique roll configuration with adjustment capabilities to control strip shape and compensate for the effects of rolling a wide range of different strip widths to very thin thicknesses.
