Ott 2 Carlos Morone 3 Abstract Typically forged steel cold mill work rolls are manufactured with a nominal chromium content of 2%, 3% or 5% based on the roll specifications for a given mill application.Type of Longitudinal Rolling Mills | Metals | Metallurgy,The mill consists of two groups of rolling stands with 5 to 6 rolling stands in each group. In the first group of stands the bloom is rolled into billets of 120 x 120 mm 2 cross section and in the second group it is further rolled to 55 x 55 mm 2.There is arrangement of transfer tables to take out the bigger sections from the first group of stands without going through the second group.Rolling Process: Working, Application, Defects, Type of,,5. Cluster Rolling Mills: In this type of rolling mill, there are two basic roles that are backed up by two or more rolls which are bigger than those two basic rolls. These backed up rolls give more pressure to the basic rolls to heavily press the strip.

1. Hot rolling and rolling defects: 1.1 Front and back,
1.8 Rolling defects: Mill spring is a defect in which the rolled sheet is thicker than the required thickness because, the rolls get deflected by high rolling forces. Elastic deformation of the mill takes place. If we use stiffer rolls, namely roll material of high stiffness or elastic constant, we could avoid mill spring.Rolling presentation - SlideShare,09-11-2016· 4 ROLLING MILLS (classified as number of arrangements of rolls) 1.
