Rolling mills are heavy tools that have steel rollers. Electric machines are used to rotate these rollers. It is used for changing the shape or thickness of any metal or a sheet of metal. It is also used to increase the hardness of the material. Paper Mill

Control of hot-steel rolling mills aims at raising the levels of quality of the related industrial production and at minimising the cost of the electric energy consumed by such industrial units. This paper proposes a non-linear optimal control approach for the hot-steel rolling mill system.The article considers the results of modernization of the main electric drive of a finishing stand of a hot rolling mill. A functional diagram of the new microprocessor control system of the electric drive is presented. Distinctive features of this system are distinguished. With the help of the new mill diagnostics system transient processes of the stator and rotor currents of the drive ...

Here, we review 90 hot rolling mill scheduling publications from 1989 to 2020 and classify them according to the details of the respective investigation. This review serves primarily two purposes.Tandem rolling can be even more advantageous when integrated with continuous casting. The tandem cold rolling process is composed of treading, acceleration, run speed operation, deceleration and tailing out. Figure 3 illustrates a typical speed diagram for tandem cold rolling. It shows the threading is the first phase of the rolling.
