In multi-stand cold rolling mills an accurate synchronization of the mill drives is necessary for a good product quality and for a safe process operation. During the standard commissioning procedure the control performance of each drive is optimized individually. However, in normal operation mode the performance is then not always optimal due to the coupling of the drives by the strip being rol...

The paper shares experience gained in application of dynamic Bayesian approach to control problems in the field of metal rolling. The contribution introduces basic notions of theory applied and provides the algorithmic as well as application-oriented solutions developed. Specifically, the consistent use of the approach resulted in an advanced decision support system for operators of a reversing...

Reaction of the airways to inhaled Berodual was evaluated in two groups of metallurgists surveilled by systematic, complex medical examinations for appx. 25 years: 31 coke oven and 31 cold-rolling mill workers. All subjects under examination were active smokers, smoking more than 20 cigarettes a day. The frequency of ventilatory disorders (central bronchi obturation, small bronchi obturation, a...

In the paper we rewiev the experience with the steel from Cold Rolling Mill Kraluv Dvur near Prague, where the steel for barrel module 0 prototype of the TILECAL calorimeter was fabricated. The measurements of the tolerances, mechanical properties and the chemical composition are presented.

In this paper an analysis is done on the main drive of rolling mill which consumes about 60 to 70 % of total energy of the plant. The existing rolling mill in India are using the 3 phase induction motor and flywheel to drive the rolling mill. The electric motor transmits the power to flywheel with the help of V-belt. An attempt has made after analysis of existing mill that by using some soft st...

Flatness measurement using shape-rolls has been used in cold rolling mills for a long time. The benefit is obvious since the measured flatness profile can be used directly to control roll bending, tilt and cooling profile. It was therefore integrated in the mill control system at an early stage to control the strip shape against a target I-unit profile. However, since the flatness is also affec...
