✦ Synopsis

The melt-drag single-roll thin strip casting process is investigated via a numerical model, which takes into account fluid flow and heat transfer with phase change. Boundary-layer coupled equations for momentum and energy along with a generalized enthalpy formulation extend the computation to the liquid, mushy and solid zones of the cast. The process variables investigated are heat transfer coefficient at roll/cast interface, casting speed and pool melt temperature, and they are analysed in terms of strip thickness and growth rate. The parametric study is conducted for AISI SAE1020 steel. Preliminary findings indicate that the heat transfer coefficient at the roll-caster interface has to some extent similar importance in determining the final strip thickness to the residence time which is a function of pool height and drum speed.
