This paper deals with the estimation of the contour of heavy plates during the hot rolling process. Asymmetric rolling conditions lead to a non-rectangular contour. The reasons for this effect, e.g., temperature gradients or nonhomogeneous input thickness profiles, are hard to predict in a real rolling mill. Hence, feedforward compensation of these disturbances is difficult, whereas feedback co...
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. Wusatowski's model which is developed to give an account of spreading is specified and a similar model to...

The continuously annealed low-carbon-steel strips from industrial production showed an average aging index of about 30 N/mm². This increase in yield strength caused by the continuous-annealing process was strongly dependent on soaking temperature and time. Whilst optimization overaging parameters use a higher annealing would reduce ageing susceptibility strips, it considered unlikely that its m...
Abstract: We present in this paper a two-years long experience of cooperation between industry and research for the resolution of a real world problem. After the presentation of the industrial context, we develop the theoretical and experimental studies and results in order to find the best architecture of neural networks to preset parameters of a temper mill machine in steel industry. We discu...
Cold rolling of steel is one of the most important metal forming processes so an accurate control of its parameters during the process is necessary. In this paper, the friction coefficient has been proposed as a function of cold rolling parameters such as forward slip, forward and backward tensile stresses ,strip thickness, static deformation, resistance of strip before and after rolling ,strip...
Several authors described experiments aimed particularly at determination of demandingness of piercing processes, namely with respect to piercing mandrels or their stress load, similarly as e.g. at technology of piercing of extremely high blanks Skripalenko et al. 1 or piercing of continuously cast ingots from alloyed steel 2 . Komori 3 dealt with mathematical simulation of piercing according t...
