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.
31-03-2015· ThyssenKrupp Steel Europe spent a quarter of a million euros on renovating its hot-strip rolling mill in Duisburg. The animation shows how it all works.
John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014. 2.1 Hot Strip Mill Evolution. Hot strip mills have evolved in various steps from original tinplate and sheet rolling mills. The development of semi-continuous and continuous multi-stand mills followed, producing small-diameter and eventually large-diameter steel coil products.
A major steel producer was not satisfied with the performance of the four-row tapered roller bearings that were installed in its cold rolling mill: steel shavings from the production process were getting into the bearings and having a detrimental effect on reliability.

Molten steel refined in the converter is solidified in this process to produce billets of a given shape. The molten steel discharged from the converter is continuously poured with a ladle into a mold below for cooling. After the steel is cooled and solidified, it is cut to a given length before it is conveyed to the rolling process for shaping.
Kubota's Rolling Mill Rolls Support the World Steel Industry. In 1961, Kubota became the first company in the world to adopt the "centrifugal casting" method for the production of mill rolls. It enables to produce a multi -layer composite rolls , which revolutionized mill roll material .
tandem rolling mill or continuous rolling mill: tandem rolling mill process. It is a modern rolling mills and the rolling is done by one pass. The rolling is done in several passes for traditional several stands and reduction that take place successive roll. The number of stands like as 2 to 18. Those are either hot or cold rolling mill types.
Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semifinished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.

In roughing mills, equipment is used to reduce the thickness of the steel while at the same time extending the overall length, to form the metal to roughly the final thickness. The Hot Finish mill forms the strip to the final dimension.

A Z-Mill or Sendzimir Mill is a machine for rolling steel. Unlike a traditional rolling mill this 20-high cluster mill configuration utilizes cascaded supporting rolls to apply force on the small work rolls in the center. This allows the application of a higher roll pressure without bending the work rolls, which would result in poor metal quality.
At a rolling mill, blooms and slabs are further rolled down to intermediate parts such as plate, sheet, strip, coil, billets, bars and rods. Many of these products will be the starting material for subsequent manufacturing operations such as forging, sheet metal working, wire drawing, extrusion, and machining.
A twin-stand Steckel Mill combines Steckel technology and tandem rolling. This mill type gives you the capacity to produce high-quality hot strip on a Steckel mill at production rates of 1 - 1.2 million t per year (without roughing stand) or up to 1.8 million tons per year with roughing mill.
Hot rolling. This process stretches a slab into a strip. The slab is reheated to approximately 1250°C and rolled in hot conditions. The resultant strip steel is wound into a roll like toilet paper (hot coil). Chains for lifting; Toughrollers; Conveyor chains for conveying semi-finished products

Cold rolling is accomplished by processing steel strip through a series of tandem rolling mill stands. Each stand has vertically stacked rolls that are powered by huge motors to impart high compressive stresses into the strip. Hot-rolled, pickled coils are fed into the cold rolling mill from an entry-
