PRIMARY COLD REDUCTION (DARON LLOYD MANAGING DIRECTOR, LECHLER LTD) PREAMBLE In the process of Rolling the most significant aspect is the generation of heat through friction and deformation in the roll bite and in a typical Cold Tandem Mill, work roll temperatures normally fall in the range of 55oC – 70oC with strip
J.F. Cameron, C.G. Clayton, in Radioisotope Instruments, 1971. Cold-strip reduction mills. A tandem cold rolling mill usually consists of three to five stands of rollers, each of which reduces the strip thickness by about 20 to 40% so that the total reduction in one pass may be by a factor ten.. It has long been recognized that some, if not most, of the variations in thickness of strip ...

Modern rolling practice can be attributed to the pioneering efforts of Henry Cort of Funtley Iron Mills, near Fareham, England. In 1783, a patent was issued to Henry Cort for his use of grooved rolls for rolling iron bars. With this new design, mills were able to produce 15 times more output per day than with a hammer. Although Cort was not the first to use grooved rolls, he was the first to ...
In a traditional rolling mill rolling is done in several passes, but in tandem mill there are several stands (>/=2 stands) and reductions take place successively. The number of stands ranges from 2 to 18. Tandem mills can be either of hot or cold rolling mill types. Classification based on stand arrangements

The history of the Sundwig 20-high rolling mill begins in the first half of the last century, when Sundwig developed a multi-roll cold rolling mill in 1930. Just a few years later, the first alligator-type 20-high rolling mill was built, followed in 1958 by the first 20-high rolling mill .
The overall frame structure of the 20-high rolling mill has the advantages of great rigidity, bearing the rolling force along the entire width of the rolling mill through the backing bearing, and therefore the longitudinal and lateral dimensional accuracy of the strip is high. Therefore, it has been widely used in the cold rolling industry.
