The continuous tandem cold rolling of metal strip is a highly nonlinear multi-variable complex process the control of which presents additional challenges over those encountered in the control of stand-alone tandem cold rolling. These challenges arise during the passage of the weld, which joins the head of the next strip to the tail of the present strip to maintain the continuity of rolling. Th...

This work describes the application of neural networks in the modeling of hot rolling processes. This relatively new technique of Artificial Intelligence was conceived more than fifty years ago, but it only became really feasible with the arrival of low cost computer processing power. The first papers about its utilization in the hot rolling field were published about six years ago. Although th...

Strip profile control in cold rolling of thin strip is a difficult and challenge problem found in industry. Currently using the novel type of strip rolling mill, such as the work roll crossing and shifting is the one of the main methods to control the strip profile quality in cold rolling. In this paper, 3-D finite element simulation models of the thin strip profile in cold rolling for the work...

Lubricant is vital to improve energy efficiency and workpiece durability for the moving counterpart. High-temperature lubricants are important hot rolling process reduce force protect roller strips. The current paper concerns eco-friendly sodium metasilicate as a high-temperature lubricant. A mill employed evaluate lubrication effect of metasilicate. influence crucial factors concentration lubr...

Steel production is a complex process and finding coherent and effective schedules for the wide variety of production steps, in a dynamic environment, is a challenging task. In this paper we propose a multi-agent architecture for integrated dynamic scheduling of the hot strip mill and the continuous caster. The scheduling systems of these processes have very different objectives and constraints...

The technology of hot flat rolling is a complex technological process that includes multiple shaping steel billet, the temperature bullet ranging from 1100 to 900 degrees [1-6]. To deform workpiece, mill rolls are used. control over workpiece thermal state an important task aimed at quality its manufacturing [7-13]. achieve goal, mathematical model developed for calculating billet state. makes ...

In this study, the effect of cold rolling process on the microstructure and texture evolution in 1wt. % Si non-oriented electrical steel was investigated. For this purpose, all samples were processed through single-stage hot rolling at 1100 ° C and two-stage cold rolling (cross rolling and unidirectional rolling) with intermediate annealing at 650 °C for 35 seconds. Finally, all of them were fu...
