Tandem cold rolling mills are named by their stand arrangement and designed as “sheet mills” if they reduce hot band to sheet gauge or “tin mills” if they roll the same incoming material to tinplate stock. A typical five stand tandem cold rolling mill is illustrated in Figure 1. Figure 1: A typical five stand tandem cold rolling mill
on wear is another issue. Stresses from Hertzian pressure in 4-high cold mill back up rolls were measured years ago, the results were never published, but of high interest also, maybe later. K. H. Schröder July 2003 K. H. Schröder: A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING MILL ROLLS File: SCHROEDER_ROLLS_010703.DOC
Combination: A combination rolling mill is a versatile “two-in-one” type of metal rolling mill that permits both 2-HI and 4-HI rolling operations. Tandem: Tandem rolling mills are used for multiple pass rolling, combining two or more mill stands. Tandem mills are often used with turks heads, edgers, dancers, inter-stand tensiometers, payoff
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

Oct 24, 2001· Table 1, Table 2, Table 3, Table 4 present the results of 6-stand tandem cold rolling mill for low carbon steel. The results presented in Table 1,Table 2 were obtained by distributing the strip thickness in arithmetic, geometric and harmonic series, for the case in which the reduction in the final stand is not fixed.

QMOS enables users to schedule the production of the steel plants in the Melt Shop and the Rolling Mill while optimizing the process and yield. The schedule, along with real time production and quality information, is disseminated to the steel mill operators and managers empowering them to take immediate and informed actions if and when necessary.
Rolling is an important steel production process. Productivity and quality improvements in metal rolling are possible by paying a detailed attention to the various roll failure modes.A proper understanding of the causes of roll failure modes is
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
