rolling mill, dedicated roll cooling systems are required to fulfill the required functions. Examples are suitable roll cooling and lubricationsystems to fully utilize the advantages of HSS rolls in hot strip mills, and selective roll cooling systems as a method to control the flatness of the strip in cold rolling mills.

Roll materials are selected for strength, rigidity, and wear resistance. Roll materials vary dependent upon the specific metal rolling process. Common roll materials are cast iron, cast steel, and forged steel. Forged rolls are stronger and more rigid than cast rolls but are more difficult to manufacture.

x The initial hot-working operation for most steel products is done on the primary roughing mill (blooming, slabbing or cogging mills). x These mills are normally two-high reversing mills with 0.6 -1.4 metres diameter rolls (designated by size).

It reduces the height as the top roll is required to be raised or lowered. This may help in increasing the output of blooming mill by at least by 5-10%. • The shallow pass in place of barrel pass prevents the requirement of stepped entry roller before Blooming mill.
