Modeling and simulation of primary solidification process of steel

Abstract

This paper provides a modeling of the phenomenon of solidification and cooling of continuously cast semi-finished, based on the finite difference method. Also, to validate the model and conducted a simulation with “Tirsim” program. In the process of continuous casting, the melting pot is passed, through the intermediary of the distributor, in the water-cooled crystallizer tank. In this way, a crust forms here which is solidified at the exterior, and one of the great problems is its cracking or even it's tearing, due to several factors. This phenomenon determines the stopping of the technologic process and significant economic losses.
