Sandvik Materials Technology(SMT) is working to improve the automated hot rolling process which is based on models from ABB that are used to predict the variables in rolling mills. The task is to identify existing models and improve those that need improvement, and replace those which have better alternatives with the help of MIKRAB Toolbox.
Intentions for the project
- Modeling the Hot rolling process to determine optimum rolling schedules
- Modeling the annealing process
- Optimization of recrystallization and annealing
- Achieving a final microstructure with just one special type of carbide and less or no other types of carbides
- Fine grain size in final microstructure
- Homogeneous material properties due to homogeneous microstructure in all bands
- Reasonable tolerance in thickness and flatness
