As per the requirement of the process and arrangement of the rolls, the rolling mill rolls can be divided into the following categories: High Rolling Mi...
Nonlinear Coupled Vibration Model of Hot Rolling Mill Rolls. According to the structure diagram of the fourhigh hot rolling mill shown in Figure 1, we consider the structural constraints on the roll and the effect of dynamic rolling force, the nonlinear spring force exerted by the hydraulic cylinder in the vertical direction, and the friction force change caused by the rolling speed ...

In hot rolling, wear of the work roll takes place mainly because of: (i) abrasion of the roll surface due to contact with the strip, and in a four high mill, due to contact with the backup roll also (ii) fatigue of the surface layers due to the variable nature of mechanical stresses applied by the strip and the backup roll
Abstract. In order to build high accuracy integral dynamic models of cold rolling mill system, by analyzing the vibration process of cold rolling, the dynamic model of 4h mill, including the rolling process model, the mill roll stand structure model and the hydraulic servo system model is built. These three models are coupled and linearized ...
The cluster mill stand has two work rolls and four or more backup rolls. The number of backup or supportingrolls depends upon the amount of support needed for the work (small diameter) rolls. Cluster mill is normally used in coldrolling operation. The cluster mill stand can have six rolls, 12 rolls, or 20 rolls.
The design of the 4 High Stand employees a large "backup" above and below the work rolls. This prevents the smaller diameter work rolls from deflecting as steel passes through the stand. The resin craftsman kit includes both aisle and drive side stand sides, the top machinery platform and simple motors, drive shaft and motor brakes.
Steckel mill A fourhigh reversing rolling mill, a Steckel mill allows the rolling of a large slab by providing heated coil furnaces or boxes on both sides of the mill to store the increased length produced during rolling Steel Alloy of iron and carbon with a carbon content of less than % Steel bath The hot, molten steel in a ...
Here are a few of the main types of rolling mills: Continuous rolling mill. Sheet metal passes through several rolling stands, each pressing the metal thinner. Cluster rolling mill. A cluster of metal rolls are lined up to be thinned out. An example of a cluster rolling mill would be a 20High Cluster Rolling Mill.
The four stand cold rolling mill is four HI equipped with CVC for a shape control system capable of producing thinner gauge of mm 2100 mm wide aluminum Alloy grade AA3104.

Rolling Mill. Description: Two High Rolling Mill * Rolling is a bulk deformation process in which the thickness of the work is reduced by compressive forces exerted by two opposing rolls. PowerPoint PPT presentation. Number of Views: 6505. Avg rating:/ Slides: 23.
1. Vertical Mill Stand The updrive type consists of a roll stand, mill spindles, a vertical gear reducer with a pinion stand and a motor. The gear reducer and motor are installed on a concrete frame to protect them from roll cooling water and mill scale.
With O scale (1:48) rolling stock running on HO scale track, it allows for the easy use of existing mechanisms and commercial track to keep prices low. HOn30 is similar, using HO scale (1:) rolling stock on N scale track. Less widespread scales include: On3, which models three foot gauge railroads and requires special On3 track.
Product description. The 4high mill is equipped with positive and negative work roll bending in order to influence the shape and the flatness of the strip. Either the work roll or the backup roll is driven, depending on customer requirements. The diameter of the 4high work rolls amounts to approximately 1:4 in relation to the barrel length.
The 2high mill consists of two working rolls only and no other supporting rolls are mainly used for "skinpass" or temper rolling. Rolling mill configuration and four high stand of reversing cold mill are shown in figure 1 and 2 respectively. Figure 1. Rolling mill configuration Figure 2. Four high stand of reversing cold mill 3.

Kim et al. (2012) analyzed the cause and characteristics of the chatter vibration in a sixhigh cold rolling mill by using multibody dynamics. However, it is difficult to incorporate coupling effects and interactions between stands in FEM model. Based on statespace methods, Hu et al. (2006b, 2006c) investigated mill stability in both single ...

The chock also prevents scale getting into the roll neck bearing. The process stability of rolling mill is significantly influenced by the clearance between the chocks and housing in mill stands. ... A cross section of a four high rolling mill stand showing roll chocks and antifriction bearing is shown in Fig 1. Fig 1 A cross section of a four ...
A 200mmwide strip is cold rolled by a twohigh mill in thickness from 2 to mm, without any spread. The rolls are 300 mm in diameter and operate at 100 rpm. If the rolling load is MN, determine the mill power required for this cold reduction, assuming typical value of lever arm ratio for cold rolling.
Fourhigh rolling mills can be put in tandem, two to seven stands, instead of a reversing mill. They can be equipped with load cells to tell the separating force and hydraulic or mechanical screw downs, depending if it is hot or cold rolling. Sometimes mechanical screw downs are preferred when there is a risk of fire.

Introduction. Fourhigh mills are mainly used for rolling foils, sheets and plates and account for a large percentage of all mills. The speed of contemporary fourhigh mills has reached . m/min to meet demands for rolling of foils and sheets.. However, frequent burning of endthrust bearings in the workroll assembly can disrupt the production process.
