2 Rolling Mills Revamp: Roll Upgrades for Extreme Loads Introduction Market Overview Today's rolling mill market environment can be characterized by low investment in new equipment and higher requirements for output. The mills are getting older, but to increase productivity, their operational loads are becoming much heavier.
The first rail rolling mill was established by John Birkenshaw in 1820, where he produced fish bellied wrought iron rails in lengths of 15 to 18 feet. [8] With the advancement of technology in rolling mills, the size of rolling mills grew rapidly along with the size of the products being rolled.

In a metal rolling process, rolls, stands, bearings, housing, motors, and other mechanical equipment are all a necessary part of the manufacturing operation. The place where all the equipment for metal rolling manufacture is set up is called a rolling mill. …
The rolling mills could be either reversing or nonreversing type. In the reversing type, which - is the most common one, the direction of motion of the rolls can be reversed, and therefore the work can be fed into the mill from both sides by reversing the direction of rotation of rolls.The process may be
Rolling mill consisting of four rolls or known as a 4 High rolling mill is used for reducing material to extremely small thicknesses. Through the use of larger backup rolls, the issues of roll deflection can be avoided and smaller work rolls can be used.

Mill rolls are driven by large several thousand horsepower motors. Rolling mills are computer controlled with complex automated drive systems. Overall, rolling mill equipment is expensive and can take a long time to repair or replace, even when slight damage occurs. Types of mills include blooming, bar, rod, plate and strip mills.
Flat Rolling •Roll Force: F= LwY avg •Roll-strip contact length L •Average strip width w –despite the fact that spreading, or an increase in width, may actually occur if edger mills are not used •Average true stress of the strip in the roll gap Y avg •Assumes no friction and thus predicts lower roll force than the actual value

Cold pilgering is a rolling process for metal tubes that reduces diameters and wall thicknesses. The Process. Located inside the tube is a stationary mandrel (1) which tapers in the rolling direction. This is attached to a long mandrel bar (2) which is secured in, and rotated by, a thrust block. Two dies (3) "form" the tubular stock in the same way that a rolling pin rolls out pastry.
