THE DEVELOPMENT OF THE THEORY OF METAL ROLLING AND ITS APPLICATION TO ROLLING MILL CONTROL INTRODUCTION In the realm of process control it is the rigidness of specifica- tion upon the finished product which dictates the refinement neces- sary for adequate control. As the end product becomes more and more critical the solution to the control problem can no longer be

The new rolling mill will be integrated with the still mill, through innovative and sustainable technologies. The goal is to realize it by the end of 2022 thanks to the experience of the Duferco technicians and to the strong collaboration with SMS Group, technology partner and supplier for the project. An ambitious project looking to the future.
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
In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in equipment, rolling is done in the ...
Modern rolling practice can be attributed to the pioneering efforts of Henry Cort of Funtley Iron Mills, near Fareham in Hampshire, England.In 1783, a patent was issued to Henry Cort for his use of grooved rolls for rolling iron bars. With this new design, mills were able to produce 15 times more output per day than with a hammer. Although Cort was not the first to use grooved rolls, he was ...

The roughing mill is made up of Multiple independent rolling mill stands, Billets heated in the furnace until they glow bright orange-yellow are rolled through one stand at a time to produce transfer bars suitable for finish rolling. High-pressure water-jet nozzles clean the oxidized iron, or scale, from the surface along the way.
5. Cluster Rolling Mills: In this type of rolling mill, there are two basic roles that are backed up by two or more rolls which are bigger than those two basic rolls. These backed up rolls give more pressure to the basic rolls to heavily press the strip.

What Is A Rolling Mill? In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to …
6 Rolling Mills Revamp: Roll Upgrades for Extreme Loads Figure 5: Roll load and fillet radius detail. Case Study – Existing Solution and Problem Description This application is performed on rolls of 2-HI mills, but could be extended to the back-up rolls of 4-HI mills. Figure 5 shows the roll load and current fillet radius detail.
The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.

They are reheated in the soaking pits and are hot rolled next, in hot strip mills. The layers of scale are removed by pickling and further reductions are obtained by cold rolling. One of the traditional aims of hot rolling is to reduce the size of slab at as high a temperature as possible, thereby reducing the mill loads and increasing the tonnage.
These factors are especially important in hot rolling that aims at uniform refined hot rolled microstructure. ... The problems associated with the use of conventional rolling mill models are ...
