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.

G. Engberg, L. Karlsson, in Fundamentals of Metallurgy, 2005 Hot rolling. Mill data from the hot strip mill has been used to calculate the mean flow stress in each pass, assuming the material to be elastic – ideally plastic. The roll force model used was a classical slab method with constant friction assumed in the roll gap. For the roughing mill (reversible 4high) both roll force ...

SMS DEMAG Hot Strip Mills 8 The coilbox arranged between the roughing stand and the finishing mill of a hot rolling mill forms coils of transfer bars, thus serving as both material and heat accumulator. During uncoiling, the former transfer bar tail runs into the finishing mill as transfer bar head. The coilbox is employed in new facilities ...

reversing cold rolling mill, which takes relatively inexpensive capital investment, is put into use. The reversing cold rollin g mill is used mainly for producing coils of normal carbon steel in emerging countries, and is used for producing small lots of variet y coils of highgrade steel or special steel in advanced countries.

17/03/2014 · A reversing mill is a rolling mill in which the workpiece is passed forward and backward through a pair of rolls. The reversing mill is so named because the steel runs back and forth between the rollers, reducing the thickness incrementally with each pass. A reversing mill can be used to reduce material to gauge.

Hotrolled, pickled coils are fed into the cold rolling mill from an uncoiler and continuously reduced in thickness by each stand to attain the desired thickness. Upon exiting the last Mill Stand, the strip is then recoiled. Reversing Cold Mill The Reversing Mill is another method of cold reduction.
