Abstract

This article examines the problem of efficiently determining heat transfer in the secondary cooling zone (SCZ) of a continuous caster. An analytical method is developed to solve this problem. The method is based on the notion that it is necessary for the cooling rate on each longitudinal section of the SCZ to be equal to the sum of the amount of heat released at the solidification front and heat flux corresponding to the prescribed rate of cooling of the metal that has already solidified. The accuracy of the proposed method is checked by using an adapted mathematical model of continuous steel casting that is based on a differential equation which describes nonsteady heat conduction. Results which are presented from numerical experiments show that the temperature field of the solidified part of the ingot, which conforms to the cooling rate established by using the proposed method, is characterized by a uniform decrease in temperature through the entire thickness of the ingot.
