Theoretical Analysis on the Solidification Profiles of Slab in Straight Type Continuous Casting Machine

Abstract

A mathematical model for the estimation of the solidification profiles of the slab in the continuous casting machine with a straight mold has been developed with the aid of integral-profile method. In this model, a mushy zone is taken into account and the heat transfer from the pool of molten steel to the mushy zone is described in terms of the heat transfer coefficient on the surface of liquidus line.
The general varidity of the model mentioned above has been confirmed by comparing the empirical data obtained by the other investigators with the profiles of mushy zone calculated from this model.
Effects of the casting speed and the cooling conditions on the solidification profiles have been determined by the use of the model proposed in this paper.
