✦ Synopsis

An extension of the analytical model for vertical continuous casting of bars previously developed by the authors (Johnson and Cherukuri. Proc. Roy. Soc. London A 455 (1999) 227) is presented. The new features include temperature dependence of thermal conductivity and the constitutive equations. The model can be used to readily predict the e!ect of various process parameters such as cooling conditions, liquid pool pressure, casting speed on the solidi"cation process. Consequently, it can be readily implemented in a control system to adjust the process parameters of a typical solidi"cation process. In addition, it can also be used as a guide to gain insight into the nature of the solution prior to conducting more general and expensive "nite element simulations.
