Jul 16, 2014· Cold rolled is the next step along the line of flat-rolled steel products. The process starts with hot rolled P&O. Hot rolled is processed to a final thickness that is heavier than most sheet products. A cold-reducing process is used, which results in a thinner thickness. The cold reduction starts with tension to the sheet.

Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.
A series of cold rolling operations are to be used to reduce the thickness of a metal plate from 50 mm to 20 mm in a reversing two-high mill. Roll diameter = 600 mm, and coefficient of friction between rolls and work = 0.15. The specification is that the draft is to be equal on each pass. Determine (a) minimum number of passes required.

John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014. 7.17 Reduction of Local Buckles. Even though the cold mill itself may cause local buckles, the majority of the local buckles are caused by the feed stock from the hot mill (Melfo et al., 2006). Therefore, proper monitoring of the hot band profile and mechanical properties will be the first choice to reduce .
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

Polytec LSV Laser Surface Velocimeter for recent upgrades on two 4-High rolling mills used for reduction & skin pass at Hagen, its location in Germany. In this case, each mill utilizes stand-alone LSV sensors for strip measurement. The application at each roll mill required a set of two LSV's, one located on either side of the mill.
30,000 PSI. As soon as it is cold reduced, and depending upon the amount of reduction, the yield strength can go as high as 100,000 PSI as the material under the work roll hardens. However, as further reduction increases the yield and tensile become about the same and the material will become extremely hard or brittle.
