Numerical Modeling of Diffusion Boundary Layer in Strip Casting Process of Carbon Steel

Abstract

This paper is aimed at the investigation of the diffusion boundary layer near the cooled casting surface encountered in the horizontal continuous casting process of carbon steel. The strip casting process is a relatively new continuous casting process. This process makes it possible to produce high-quality flat steel products directly, without using hot rolling. This explains why this process is very attractive for industry. Extensive numerical simulations under equilibrium and nonequilibrium assumptions provide valuable insight into the physics of diffusion boundary layer.
