Outline of reversing cold rolling mill and rolling method As illustrated in Figure 1, a reversing cold rolling mill is structured mainly of a mill proper, a winding machine (pay-off ree l), an entry winding machine (tension reel) and a delivery-winding machine (tension reel).
At Precision Rolls Inc., our custom-manufactured products, emphasize our dedication to quality and finish of the roll. Ours is a 45-year history of hands-on control and resultant superior quality of finished parts for major industries, including steel, plastics, aluminum, …
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.

Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening.
It has a roll stand with four parallel rolls one above the other. The top and the bottom rolls rotate in opposite direction as do the two middle rolls. The two middle are smaller in size than the top and bottom rolls which are called backup rolls for providing the necessary rigidity to the smaller rolls. A four high rolling mill is used for the hot rolling of armor and other plates as well as ...

REVERSING COLD MILL Advanced reversing cold-mill technology from Primetals Technologies is an ideal solution for small- to medium-sized production capacities, or for the rolling of smaller order lots of special steel grades.
It can come from a previous bending operation (for instance, the exit passline roll in a slitting line is notorious for putting in reverse coil set) or just from coiling the coil in a cold mill, a hot mill, or even on a tension level line.
mills and the materials started to gain popularity. High density polyethylene doctor blades From the early 1980s, paper machines became considerably faster and wider, and soft rolls were introduced. The soft roll covers were easily damaged by both metal and composite blades and a new blade material had to be found. The result of that search was high density polyethylene. Poly blades are best ...
