RESUMO
The present study describes the development of a static experimental set-up representing the solidification system of a Rotary Continuous Caster, as part of a metholology, which connected to a numerical model permits to determine transient global metal/mold heat transfer coefficients along solidification. By using this methodology the influence of air gap formation between mold walls and metal surface on process kinetics has been investigated . The static simulator has the same escale of an industrial caster and is constituted of a Properzi copper wheel sector, equipped with a spray cooling system, a pouring system and a thermocouple arrangement connected to a data aquisition system. Experiments were performed using aluminum alloys of the electrical conductors industry. The heat transfer coefficients were obtained by using a method base don com pari sons of numerically calculated and experimental thermal profiles (lHCP method). The used numerical model is based on a finite difference technique and applied on a control volume from the experimental system. The results have shown that the used methodology is consistent, permitting the characterization of metal/mold heat transfer coefficients and as a consequence, to predict the solidification evolution in industrial processes
