“…During a continuous casting operation quasi-steady state condition exists, 3,4 i.e. the temperature distribution in the melt and the solid is independent of time but depends only on the spatial coordinates.…”

“…In particular, in a continuous casting process, since the casting rate and withdrawal rate are generally maintained constant, the heat transfer phenomena associated with solidification can be safely modelled assuming the quasi-steady state condition. 3,4 Experiments on crystal growth of pure tin by OCC process were carried out Wang et al 5 and temperature profile along the axis of the growing crystal and the melt were measured. A computer model for heat and fluid flow was also developed to verify the observed temperature profile.…”

The Ohno continuous casting process, associated with unidirectional crystallisation of high purity metals, is of practical importance because of its increasing applications in electronic industries. This paper deals with analytical solution of axisymmetric heat transfer during solidification of pure metals in this casting process. The two-dimensional quasi-steady heat conduction equations for solid and liquid phases along with associated interface and boundary conditions are solved by the method of separation of variables. The expressions for temperature field in the melt and the solid regions are obtained as a function of various model parameters such as Biot number, Peclet number, dimensionless latent heat of solidification and liquid to solid thermal conductivity ratio. Besides, the casting rates of three different pure metals are compared for the known operating conditions.
