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...

this paper is concerned with investigations into the effect of tension between the stands of the finishing mill on width control in a hot rolling process. an analysis is given to predict satisfactorily the variation in width due to spreading and also due to strip tension between the stands. wusatowskis model which is developed to give an account of spreading is specified and a similar model to ...

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...

The application of Generalised Predictive Control (GPC) for an experimental hot-rolling mill is presented in this paper. GPC has been implemented to provide the mill with good speed control and regulation when steel and aluminium hot-rolling experiments are carried out. Using an identification mechanism, GPC first estimates the mill’s model and predict the future behaviour of the rolling speed ...

Hydraulic bending roll system has become one of key equipments to control the exit strip shape in strip rolling mills. The hydraulic bending roll system of a hot rolling mill was researched and analyzed, and its mathematics models were founded in whole based on the action principle of some representative hydraulic components. At last, the hydraulic bending roll system was simulated with MATLAB ...

transfer table is an essential stage between roughing and finishing rolling stands in a hot-strip rolling mill. high temperature and long time that strip is exposed to air at this stage cause a considerable heat loss that accounts for uneven temperature distribution, non-uniform surfaces, reduced product quality and increased production costs. using thermal shields on the transfer table is cons...
