Abstract
An existing and in-use online transient three-dimensional heat transfer model (3DHTM), combined with a solidification and microstructure model (interdendritic solidification model - IDS) for the continuous casting of steel is presented. The 3DHTM and IDS are integrated into a single online software entity and this has been installed in the automation systems of three slab casters in Finland. The development of this integrated concept is an ongoing combined effort of several universities, one SME and industrial partners in Finland. The principal objective for this integrated entity is to provide phenomena-based predictions for solidification and microstructural changes during continuous casting in online plant use, including quality indices as well as accurate calculation of liquid pool shapes and end locations. The microstructural phenomena and the related quality indices developed will be used for quality prediction. Quality indices between those calculated by the IDS and a steel mill's quality database have been compared to validate the quality prediction capabilities of the IDS. The tools and industrial case examples are presented.
