SUMMARY:Phenomenon based model for virtual hot strip rolling
DESCRIPTION:Digitalization is taking a bigger role in the steel industry. Models for predicting mechanical properties, metallurgical phenomena, roll forces and microstructure have been commonly used in development of novel steel grades. These individual models may predict certain phenomena thoroughly, but input values are usually based on an assumption or on a “good guess”. To produce reliable boundary conditions for these models of individual phenomenon a virtual rolling model is developed. This model computes the whole process of the hot strip mill from roughing to accelerated water cooling on a run-out table. Strip location and temperature evolution is calculated continuously. Thermal and thermomechanical (rolling stands) boundary conditions are placed according to process layout. Input data for the model is automatically read from raw process data.
Rolling parameters are calculated using a coupled ARCPRESS model which calculates normal and frictional shear stress distributions in the roll gap predicting roll forces and displacements of the work roll surface. Calculations for static recrystallization are considered in evolution of flow stress. Phase fractions during water cooling are calculated as well. The virtual rolling model minimizes the need for parameter speculation for each simulated process. All the input values are read from actual process data and the metallurgical and mechanical state of the strip are computed through-out the whole process.
