5. Cluster Rolling Mills In this type of rolling mill, there are two basic roles that are backed up by two or more rolls which are bigger than those two basic rolls. These backed up rolls give more pressure to the basic rolls to heavily press the strip.
Rolling processes 51 introduction Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure 51. Fig. 51 Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.
Four high rolling mills Cluster rolling mills Planetary rolling mills Tendem or Continuous mills 1. Two High Mills. It contains two heavy rolls fixed one over the other. The rolls are supported in bearing housed in sturdy upright frames called stands which are grouted to the rolling mill floor. The vertical gap between the roll is
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

Rolling Mills . In metal forming industry, rolls themselves do not function in isolation. In a metal rolling process, rolls, stands, bearings, housing, motors, and other mechanical equipment are all a necessary part of the manufacturing operation. The place where all the equipment for metal rolling manufacture is set up is called a rolling mill.
