Metal cooling and solidification in a continuous-casting mold

Abstract

A mathematical model is proposed for cooling a metal solidifying in a continuous-casting mold. In this model, heat exchange is related to solidification; therefore, the thermal resistance of the gap between the ingot and the work mold surface, which is the main component of the total thermal resistance to heat transfer from the ingot to cooling water, can be calculated. This mathematical model is applied to the cooling and solidification of an ingot in a continuous-casting mold, and some numerical-calculation results for the case of a medium-carbon steel are presented.[PUBLICATION ABSTRACT]
