Abstract

Un método para fundir una carga de aluminio que tiene no más del 4% de sal por masa, que incluye durante una fase de fundición, introducir combustible y oxidante vía un quemador que funciona a un primer índice de encendido, el combustible y el oxidante reaccionan para formar una zona de combustible por encima de la carga de aluminio, finalizar la fase de fundición y comenzar una fase de transición cuando la carga de aluminio está casi completamente fundida, durante la fase de transición, reducir el índice de encendido del quemador a un segundo índice de encendido más bajo que el primer índice de encendido, introducir un gas no oxidante a una primera velocidad para formar una zona no oxidante entre la zona de combustión y la carga de aluminio y permitir que la carga de aluminio se funda completamente y finalizar la fase de transición y comenzar una fase de golpeteo luego de que la carga de aluminio esté totalmente fundida y, durante la fase de golpeteo, verter la carga de aluminio fundido fuera del horno.
