Typical upgrades to hot mill stands include the addition of roll bending for profile and shape control as well as the installation of hydraulic roll force systems for automatic gauge control. Customers are also looking to see production improvements by eliminating mill down time through shorter roll changes.

ArcelorMittal in Riverdale in 2012. The steelmaker says it doesn't make sense to keep all its hot strip mills at a time when they're so underused.

A cobble will occur when there is a roller malfunction, the line of steel deviates from the roller path or, as mentioned above, the end of the steel splits. All of a sudden the continuous roll of steel will come to an abrupt halt although the steel behind is still being pushed through the working rollers at speeds which can reach up to 30 mph.

SBQ3, BEST, and H3 are the latest technologies applied to production processes for special bar quality, special steel, commercial steel bars, and high-speed wire rod rolling mills.

discuss proper roll handling during removal, storage, transport, and reinstallation. Finally, ceramic roll conditioning is discussed. It allows for returning the roll to its original finish while the roll is still in the machine. This eliminates both a roll change and the maintenance costs associated with the change.

roll gap, therefore considerable dead time has to be taken into account in thickness control. The rolling force can be measured by a load cell or can be calculated from the pressure of the HGC cylinders. Due to several reasons (deflection of the rolls caused by the rolling force, the thermal crown and the ground crown), the roll gap ...

Roll "performance" is a vague term that may concern: mass or length of hot steel produced per millimetre of machined roll diameter, or per mass of roll material used; or total tons of the product processed per set of rolls or per roll change. Calibre rolls have wear resistances of about several hundreds tons of hot rolled steel per millimetre ...
