In order to study the hot Compact Strip Production (CSP), fourhigh mill vibration characteristics, and vibration suppression method, the roller system structure stability was analyzed and calculated at first in the paper. And then, the mill stand gap was measured at field and its influence on roll transverse vibration was analyzed. The drum gear coupling effect on the roller system stability ...
The central element of the plate mill is made up of fourhigh rolling stands with processcomputer control, on which rolling is performed in widening and elongating passes. ... of around 1,200 deg C which is suitable for plastic deformation of steel and hence for rolling of the steel in the rolling mill. Highpressure scale removal is performed ...
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

In this type of Rolling Mill, the Rollers rotates in Opposite direction and their direction changes after each Metal pass. The Metal (Ingot) is passed continuously and approximately 2530 passes are required to convert Ingot to Bloom. (ii) ThreeHigh Rolling Mill: It consists of three high stands and three Rollers present in the same vertical ...
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 descaling operation on a Hot Strip Mill (HSM) uses high pressure water jets to remove the thick, hard and brittle oxide scale, in order to avoid oxide embedding into the metal which degrades ...
To develop an analytical method for spatial vibration analysis of rolling mill, a 250 mm (diameter of the roll) highstiffness rolling mill (without housing) is taken as an object for shown in Fig. 2, the upper and lower chocks are connected by two square columns and two rods with left and right between chocks and square columns are slots and the square column ...
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.
The versatile Waterbury Farrel 4Hi Mill can be deployed as both a nonreversing mill for intermediate rolling and as a reversing mill for finish rolling. Smaller work rolls allow for more efficient material reduction. The larger backup roll positioned against the smaller work roll reduces separating forces and permits the rolling of wider and ...
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 ...

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.
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 plant's new fourhigh rollingmill stand (Fig. 1), with work rolls having a body 4550 mm long and special auxiliary equipment, makes it possible to subject the metal to demanding conditions during thermomechanical rolling in order to produce plates with the prescribed set of mechanical properties and highly accurate dimensions that ...

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.
In steel rolling mills, slabs are rolled out to heavy plates with a certain plate thickness using reversing mill stands. ... R. Heeg, T. Kiefer, Deflection and bending model of a fourhigh mill stand for heavy plate rolling, in: Proc. of the 4th International Conference on Modelling and Simulation of Metallurgical Processes in Steelmaking ...
This plastic kit includes walls, support trusses, soaking pit details and a fourhigh reversing mill stand complete with rolling table, motor and walkway details. The interior of the walls have molded cut lines allowing easy removal of lower side wall sections to reveal the interior, just as on the prototypes.
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 ...
