Modelling and on line control of thermomechanical rolling and cooling of micro-alloyed steel

Abstract

New software for austenite transformation modelling and ONLINE coling control of the micro-alloyed steel strips was developed. The software models the optimal strip cooling curve and the share of microstructural components. After receiving information about finish rolling temperature and exit rate of the strip the software arranges the correct cooling conditions with the aim to keep the modeled optimal microstructure along the entire legth of the strip.
