Abstract Due to the growing interest in lightweight constructions, continuous casting of nonferrous metals is continuously developing as a result cost-effectiveness this process, which combines several stages sheet production. Unfortunately, because characteristics parameters roll gap, such as, for example, pressure and temperature, are unknown, significantly affects understanding phenomena occurring material during rolling. Therefore, at IMF Freiberg, sensor consisting piezo two thermocouples measuring temperature different heights was mounted on surface roll, making it possible control process live TRC trial. The measurements were further supported by digital twin form layer model, combining viscous solid region each single tool. computations tool performed offline computation time order seconds, thus much less than that finite element method. Because model measures magnesium strip, FEM simulations used validate from thermocouples. Experimental results have been obtained allow direct correlation between development length fully solidified L D part gap zone, correlates directly with effective total equivalent strain. Using train can be online estimation final strip properties process. Graphical abstract
