Recent developments for the finite-element modelling of the plastic forming of the metallic materials are described in the paper. The model consists of three parts; mechanical, thermal and microstructural components. First two are described in earlier publication and the focus here is put on the modelling of the microstructural phenomena. Two approaches are described. First uses conventional cl...

It is important to study the vibration of rolling mills improve stability production. A dynamic process model established by considering elastic recovery exit strip and influence multiroll equilibrium, accuracy verified experimental data. On this basis, based on distribution friction force in deformation zone, torque are nonlinearized. In addition, a mill structure gap piecewise nonlinear horiz...

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 ...

Due to the inaccuracy of preset rolling force cold rolling, there is a severe thickness defect in strip head after due flying gauge change (FGC), which affects yield strip. This paper establishes model (RFPM) by combining optimization (RFOM) and deviation prediction (RFDPM). The RFOM used genetic algorithm (GA) optimize deformation resistance friction coefficient models. RFDPM constructed using...
