In case of rolling mills, nonlinear controllers require a careful validation of the models and, in plain words, they require a cancellation of the essential nonlinearities of the controlled plant:System Description Another control problem (besides the continuous caster) arising in the steel industry is the control of the exit steel thickness in a rolling mill The diagram below shows the layout of a rolling mill, with thick steel going in one side, and thin steel coming out the other Overview of the ExampleRolling Mill Tutorial Control System Design The flatness control in cold rolling mill is carried out through automatic flatness control (AFC) The control tasks which are to be achieved in the Level 1 closedloop control for cold rolling mill concerns not only the thickness (AGC) but also the flatness (AFC)Shape and Gauge Control of Strip in a Cold Rolling Mill
Tandem rolling mill Wikipedia
The mill stand spring curve is obtained by pressing the work rolls together with increasing force This causes the work rolls to bend, the screwdowns to compress and the mill housings to stretch To reduce work roll bending, a much larger roll is positioned above the top work roll and another is placed below the bottom work rollFirstOpNet DCS system for Cold Rolling Mills with adaptive control The DCS control system designed by First Control is based on modern control technology with selftuning control to achieve maximal production performance Experience from several installations shows that the selftuning regulator reduces the thickness deviations by 5075% Rolling mills First Control Systems ABMill computer rooms and control pulpits housing rectifiers, variable frequency drives, programmable logic controllers and other computer equipment are very critical areas and should be provided with automatic fire protection systems There is usually no possible way of manually operating rolling mill equipment It should be noted that depending on business interruption Risk Logic Rolling Mills Loss Prevention Risk Logic
