Jan 12, 2021· A work roll is a core part of a rolling mill that enters into direct contact with rolling material to make cold rolled carbon sheets cr of the desired thickness back up roll a backup roll is the largest and heaviest roll used in rolling mills and …


A hot rolling mill and method for operating the hot rolling mill where the shape of the strip is controlled by localized cooling devices positioned at intervals along work rolls in at least three lateral zones, a central and two edge zones, and capable of separately cooling each zone to control the shape of the work rolls in that zone and inhibit the formation of shape defects …


A commonly used metric to quantify the strip profile is the strip "crown", denoted C (x). The strip crown is defined as the difference between the thickness, H (0), at the strip center, and the thickness, H (x), at an arbitrary location x, as indicated in the following equation C (x) = H (0) − H (x) (1) Fig. 4 – Examples of cluster ...


The continuous, or cross-country, mill is a third type of blooming mill. This mill has a series of two-high rolls. As many as 15 passes may be required to reduce an ingot 21 in 2 (135 cm 2) in cross section to a bloom 8 in 2 (52 cm 2) in cross section. The twoand three-high blooming mills roll the top and bottom of the steel in every pass.


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. Rolling mills often vary in the type, number, and position of rolls.


chemical contamination. This method is ideal for motors operating in harsh rolling mill environments, where the atmosphere is pervaded by damaging water mist, rolling oil and emulsion. The stator construction is designed to accommodate two alternative types of motor cooling depending upon the customer's preference or installation conditions: 1.


Rolling Mill History. Hot and cold metalworking between two or more rolls has been in existence since long before the industrial revolution. As a matter of fact, Leonardo da Vinci was credited for the metalworking mill prior to his death in 1519. When most people think of a rolling mill, they visualize sizable machinery in ferrous (iron, carbon ...


Highly productive rolling can be carried out by setting up as many rolling mills (2Hi mills or universal rolling mills) in a straight line as there are rolling passes for non-reversible rolling. It is a method that is often applied for rolling small to medium-sized shaped steel.The predominant style is the stand-exchanging method through which ...
