This paper presents an optimization approach to deal with the problem of minimizing the hot rolling time of a steel slab. Unlike traditional approaches, this work also considers the chemical composition of the steel slab as a parameter, allowing the automatic setup for different steels of the hot rolling mill. To validate the approach discussed here, a six-stand rolling mill is modeled as an op...

Self-propagating exothermic formation reactions have been intensively studied in a variety of reactive multilayer foils, such as Ni/Al, Ni/Si, and Nb/Si foils. These foils contain numerous alternating nanoscale layers of elements with large negative heats of mixing. With a small thermal pulse, atoms diffuse normal to the layering and result in a rapid exothermic reaction. The heat produced is c...

The problem of evaluation of advisory system quality is studied. Specifically, 18 advisory strategies for operators of a cold rolling mill were designed using different modelling assumptions. Since some assumptions may be more appropriate in different working regimes, we also design a new advising strategy based on the on-line merging of advices. In order to measure actual suitability of the ad...

Austenite is a semi-stable phase in most stainless steels that deforms to martensite under Md30 and forms martensitetype ά and ε due to the deformation in the steels. Since the distribution of strain induced martensite plays animportant role in achieving desired properties, the main objective of the present work is to model martensitedistribution of ά during cold rolling using...

Consumers significant economic benefits be able to use relatively inexpensive sheets instead expensive The purpose article: establishment effect various technological schemes hot rolled fine an...

The vibration of the vertical system a cold rolling mill is major concern for factory production. In production, it found that thickness control with dynamic stiffness compensation has significant impact on vibration. this work, mechanical hydraulic coupling model was established. MATLAB/Simulink used to simulate and analyze response characteristics structure considering mode position upper cyl...
