HSS is normally rolled in tandem cold mills (TCMs) that employ 4high or 6high rolling stands with workroll diameters ranging from 630 mm to 420 mm. HSS exceeding 980 MPa has been manufactured by extending TCMs with the installation of an additional mill stand.
These mills also provide improvements to the shape of rolled strip, increased reduction and greater rolling efficiency. Tandem Mill Improvements. A tandem mill replaces the first 4Hi Mill stand with a 6Hi Mill, reducing the total sequence size. The smaller work rolls in the 6Hi Mill allow a higher reduction and acceptance of thicker hot ...

Aspects of rolling on tandem fourhigh coldrolling tube mills are studied. The article examines how the gear ratio of the diagonal transmission of the stand is related to the axial force on the semifinished product and loss of stability by the tube. An improved method is developed for designing the rolls so that the deformation process is divided between a pair of breakdown rolls and a pair ...

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 ...
