A model describing heat transfer in the secondary cooling zone (SCZ) of a continuous caster is derived with the objective of reducing defects arising from improper cooling in the SCZ. A simple open-loop control strategy is proposed and evaluated to achieve this goal. An equivalent numerical model of the SCZ is utilized to identify the heat transfer coefficients necessary for obtaining an ideal or near-ideal temperature profile along the strand's midface, characterized by user specifications and dependent on the steel's properties and cooling system constraints. The study includes simulations demonstrating the application of the open-loop control approach for a low carbon 14cm x 14cm billet caster, revealing that the achieved temperature profile closely parallels the specified profile, despite potential disturbances such as casting speed variations, roller interactions, and clogged sprays. The findings illustrate the importance of addressing these disturbances to maintain an optimal temperature profile during the casting process.
