| Description
| - Material-technological modelling is one of the possible tools which helps not only to reduce the costs connected with research of new materials and optimization of recent technologies but which can also solve technological problems in the production process. The main aim of physical material-technological modelling is to identify the main technological parameters which have a major influence on the final state of the product. For this research was chosen hard formable nickel alloy with molybdenum. Hot rolling of this material often produces cracks at the edges of sheets. First of all, data characterizing pass reductions had to be collected during the rolling process and information about the duration of each pass and the holds between passes were further obtained from the set-up of the rolling mill. A thermal camera and pyrometer with automatic setting of emissivity were used to determine the temperature of the semi-product prior to each rolling pass and after it. The obtained data were used to create a physical model, which was tested on a thermo-mechanical simulator. This model was than modified to achieve the optimal distribution of deformation during the rolling process and so eliminate the creation of hot cracks. Microstructures after different thermo-mechanical processing schedules were analyzed. To compare the influence of the optimization process on the final microstructure, the results obtained on the simulator were compared with the structural-mechanical properties of the real rolled product. The modified temperature-deformation schedule was finally tested in the conditions of the real process.
