Sep 30, 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 cluster mill that this study aims is a 20-high reversible mill. With reversible mills means that once the strip has been coiled from the decoiler to the recoiler, the rolling direction is reverted and the decoiler becomes recoiler and vice versa. The mill contains of an upper and lower mill housing of rolls, see figure 1.

As a result, the entry stand gap can be used as the main control method of exit thickness, whereas rolling speed of any stand and roll gap of the exit stand can be used to adjust the inter-stand tension. The results are beneficial for thickness and tension control of the two stands reversible cold rolling mill.
Oct 01, 2012 In order to lucubrate the rolling characteristic of the two stands reversible cold rolling mill and establish the tension and thickness control strategy, the steady-state characteristic simulating program was established using the steady-state continuous rolling theory. The influences of each factor on exit thickness under different tension control methods were analyzed. The results show that ...
2 High Rolling Mill - Element. 2 High Rolling Mill. Rolling mills consisting of two rolls or known as a 2 High rolling mill is used for anything from temper pass to breakdown of material.

Jan 01, 2017 Two-stand reversible cold rolling mills, a typical layout of which is shown in Figure 1, are also called compact cold mill CCM. It was specially developed for moderate scale cold rolling plant. Strip breakage occurs frequently during the initial commission phase of some CCM, which has not been solved effectively.
The blooming mill can be divided into the following types according to its structural form. Two-roller reversible blooming mill. It can also be divided into billet roughing mill and square-slab mill. The mill size is expressed in terms of the nominal diameter of the rolls. The upper roll of the billet rolling mill has a small amount of rise ...
Highly productive rolling can be carried out by setting up as many rolling mills 2Hi mills or universal rolling mills in a straight line as there are rolling passes for non-reversible rolling. It is a method that is often applied for rolling small to medium-sized shaped steel.The predominant style is the stand-exchanging method through which ...
