Abstract Scope Accelerated cooling on the run-out table (ROT) has become a key technology to manufacture thermomechanically controlled processed steels, both hot rolled plates and strips. The use of power cooling units with increased heat extraction capacities enables efficient production of advanced high-performance steels with reduced alloying levels, but the application can be challenging for rapid cooling of thicker gauge steel products because of resulting through-thickness microstructure gradients. A mechanistic heat transfer model was constructed based on representative boiling curves obtained from systematic power cooling tests with moving steel plates on a pilot scale ROT facility. An austenite decomposition model was developed for microalloyed low-carbon steels by conducting continuous cooling transformation tests from work-hardened austenite. By coupling the austenite decomposition model which accounts for the latent heat of phase transformation with the heat transfer model, the effect of plate thickness on the through-thickness ferrite grain size was predicted for the investigated steels.
