what is the cluster mill in process

Explain planetary and cluster rolling mills with neat

By using cluster mill, very thin sheets can be rolled to very close on a mill with small diameter work rolls. Here each of the work rolls is supported by two backing rolls. It is very typical mill. The sendzimir mill is a modification of the cluster mill with 20 rolls. which is very well adapted to

Types of Rolling Mills Metallurgy

The cluster mill consists of two working rolls and four or more backing up rolls. The number of backup or supporting rolls depends upon the amount of support required for the working (small diameter) rolls. Cluster mill is generally used in cold-rolling operation. The arrangement of cluster mill is shown in Fig. 2.9 (d). Type # 5. Multi-High Rolling Mill:

Roll forming Wikipedia

Roll forming, also spelled roll-forming or rollforming, is a type of rolling involving the continuous bending of a long strip of sheet metal (typically coiled steel) into a desired cross-section.The strip passes through sets of rolls mounted on consecutive stands, each set performing only an incremental part of the bend, until the desired cross-section (profile) is obtained.
