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.
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.

The heating furnace pressure should be set at 0 ~ 30Pa higher than atmospheric pressure. If the furnace pressure is too high, the charging port, discharging port, observation hole and other opening parts will be exposed to fire. The results are as follows: (1) the furnace gas loss increases, which increases the heat loss; (2) SO 2 and other ...
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 ...

FourHigh: A fourhigh mill can be used to finish roll thin gauge stock. For narrowwidth ribbon and foil products, 6HI roll inserts are also available. Combination rolling mill: A combination rolling mill is a versatile "twoinone" type of metal rolling mill that can perform 2HI and 4HI rolling operations.
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.

Based on the analysis of the influence of roll vibration on the elastoplastic deformation state of a workpiece in a rolling process, a dynamic rolling force model with the hysteresis effect is established. Taking the rolling parameters of a 1780 mm hot rolling mill as an example, we analyzed the hysteresis between the dynamic rolling force and the roll vibration displacement by varying the ...

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.
A 3HI mill stand is essentially needed in hot rolling reversing mills without switching the order of rotation of the rolls. In this type of mill stand, there are three working rolls. The top and bottom roll rotate in the same direction; meanwhile, the centre roll turns in the opposite direction. This is important as the workpiece bar keeps ...
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.
The fourhigh roll configuration is used for rolling of plates and for hot rolling and cold rolling of steel strip. It is used both in the nonreversing and reversing rolling mills. Six high mill roll configuration In this type of roll configuration, there are six horizontal rolls, mounted in a single vertical plane. Two rolls (inner) are ...

Automatic gauge control features Element mills offer a wide range of feed back options for roll positioning that provide tight output tolerances. Our most accurate design incorporates non contact positive roll detection that can provide output to tolerances of better than +/″ (+/ 4um).
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.

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 ...
Fig. 1 shows the layout of a tandem cold rolling process. Mill vibration often occurs in stand 4 and 5 because of the high rolling speed and deformation resistance [2]. It can be categorized into torsional, thirdoctave mode and fifthoctave mode chatter [3]. Torsional chatter, in which the major frequency lies in the range of 525 Hz, causes ...

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.

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.
