New secondary cooling patterns for peritectic and micro-alloyed steel

Objetivo

Although a significant amount of work has already been undertaken to understand the initiation and propagation of cracks on the surface of the continuous casting strand and develop casting equipment and practices to reduce the problem, cracks remain a major concern for steel producers, especially for sensitive steel grades like Al grain refined, micro-alloyed and peritectic steels. This research aims to reduce the cracking proneness of sensitive steel grades by applying, during secondary cooling, a thermal treatment (intense cooling and self-tempering) to the strand in order to modify in-line its surface and sub-surface microstructure with the purpose of improving hot ductility and, in so doing, the surface quality. Modification to be brought to the secondary cooling systems will be investigated by means of numerical modelling and laboratory simulations. Plant trials will be performed for assessing the achievable surface quality improvements.
