Rolling (metalworking) - Wikipedia
Earliest rolling mills were slitting mills, which were introduced from what is now Belgium to England in 1590. These passed flat bars between rolls to form a plate of iron, which was then passed between grooved rolls (slitters) to produce rods of iron. The first experiments at rolling iron for tinplate took place about 1670.

cluster roll mill wikipedia. Rolling (metalworking) Wikipedia. To minimize the roll diameter a four-high or cluster mill is used. A small roll diameter is advantageous because less roll is in contact with the material, which results in a lower force and power requirement. The problem with a small roll is a reduction of stiffness, which is overcome using backup rolls. These backup
Z-mill - Wikipedia
A Z-Mill or Sendzimir Mill is a machine for rolling steel. Unlike a traditional rolling mill this 20-high cluster mill configuration utilizes cascaded supporting rolls to apply force on the small work rolls in the center. This allows the application of a higher roll pressure without bending the work rolls, which would result in poor metal quality.

30/09/2020· Cluster rolling mills; Planetary rolling mills; Tendem or Continuous mills; 1. Two High Rolling 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 adjustable. The rolls rotate in opposite directions and are

Cluster Mills. In all cases, one of the main advantages of a cluster mill is the large back up rolls. The back up rolls act as a heat sink because there is a considerable amount of heat energy going into the strip and the work roll. Much of the heat in the work roll is transferred to the back up roll. Having a large diameter back up roll allows the mill to run at high rates of speed compared,
Industrial History: Z-Mill, Cluster or Sendzimir Mill
23/11/2021· Z-Mill, Cluster or Sendzimir Mill. It is common for steel rolling mills to have backing rollers in a stand, but a Sendzimir mill has nine backing rollers on each side! This allows the working rolls to exert the pressure needed to cold roll harder metals such as stainless steel without bending the rolls.
