Online material characterisation at strip production (OMC)
During the last years in the steel industry the necessity has grown steadily to tune the production process to a minimum of waste, optimum of efficiency and just-in-time production of the ordered steel grade. Tools and methods therefore have to be found to fulfil these requirements. The most important step to this point is a thorough understanding and modelling of the production processes to find the optimum processing parameters. An important base for all modelling is the provision of reliable information about the actual material state. These data could only be gained by advanced methods of... material characterisation online during production. The general aim of this research project is to test methods of non-destructive material characterisation for the determination of characteristic values of the material structure like texture, phase mixture, precipitation, void and dislocation density and grain size. The parameters measured online will give valuable input to material models to predict the final product quality from the present status and to find measures for correction at deviations. Furthermore the combination of the basic quantities characterising the material state and the data characterising the related process conditions can be used to optimise product quality, output and consumption of resources and direct process control. The consortium has structured the approach of the proposal into four main working tasks for comprehensive investigation, in detail system specifications, definition of starting level, application of electromagnetic material characterisation, material characterisation by ultrasonic techniques, determination of the main disturbing influences in production lines and assessment of the results.
