Steel strip quality upgrading through optimizationof cold rolling schedules in continuous mills

As a result of research into the cold rolling theory and practice, a complex of mathematical models and model-based process solutions has been elaborated to improve quality of cold rolled steel strips and reduce energy consumption. The use of the above designs made it possible to establish a number of new regularities and employ them for cold rolling practice improvement and cold-rolled strip quality upgrading.

Increase of mechanical properties of hot plate due to introduction of a cycle of high-speed asymetry of work rolls on four-high mill 5000

In the given work results of researches asymmetric rolling on reversive mill 5000 are considered. By definition of boundary modes of asymmetry and an opportunity of application results of precomputations are resulted in production for various circuits of rolling. Results of influence of asymmetric rolling on physic and mechanical properties, structure and geometry hot sheets are shown, recommendations to introduction of modes of asymmetry in a production cycle of manufacturing of sheet-rolling production of the improved quality are
