Abstract
Digitalization is taking place in the steel industry and novel virtual rolling models will be implemented into industrial systems. Virtual rolling models are mainly assembled of individual models for modeling the rolling process considering mechanical, thermal and metallurgical phenomena. Advanced virtual rolling models even predict mechanical properties based on modeled metallurgical state. These models for certain phenomena do not usually consider the constantly changing process parameters which affect the temperature of rolled strip in the industrial process. In the hot rolling industry, temperature development is of particular importance. To calculate temperature development accurately throughout the rolling process, multiple thermal boundary conditions must be considered. In this investigation, we used the FE-model to study how parameters of rolling pass, work roll coolers and full length transfer strip affect warming of a work roll surface. These results were utilized in prediction of work roll surface temperature in contact between the work roll and the strip over full length strip rolling in virtual rolling model to model development of strip temperature in full scale industrial hot strip rolling process.
