The paper refers to an intermediate stage of the running international project ProDaCTool which aims to develop the decision-support tool for operators of complex industrial processes. It should help to guarantee stable highest quality of product by optimal settings of machinery. The main idea of the project is to extract valuable information from a huge amounts of process data and to store it ...

It is not rare to observe an inverse relationship between hot strength determined from rolling load of the finishing stands of the hot strip mill and strain. This situation was already described in the literature and is explained by the use of inverse rolling load models that assumes sticking friction in the determination of hot strength. The aim of this work was to show that this “work softeni...

In cold rolling of thin strips, i.e., foils (Thickness

Deformation behaviour of rolled AZ31 sheets that were subjected to the accumulative roll bonding was investigated. Substantially refined microstructure of samples was achieved after the first and second pass through the rolling mill. Sheets texture was investigated using an X-ray diffractometer. Samples for tensile tests were cut either parallel or perpendicular to the rolling direction. Tensil...

In this paper, properties of slab deformation in sizing press mill as one of the slab reduction processes in hot rolling mills have been evaluated using the elastoviscoplastic finite element method with explicit formulation. Effect of prarameters such as initial slab width and thickness, reduction, feed pitch, and anvil speed on factors such as dogbone formation, head and tail fishtail profile,...

Laboratory tests are crucial in education and training of engineers. Experimental equipment and process simulators are extremely expensive. It is not possible and justified economically to build such laboratories, for educational purposes, in large number of schools. On the other hand, education and training based on video films, etc., is not adequate and personal contact of students with a pro...
