Abstract

Método y aparato para medir con precisión el sobrecalentamiento, la relación de bano y la concentración de alúmina en un bano de aluminio fundido. En una realización, un detector reutilizable determina la temperatura del bano y el sobrecalentamiento de una muestra del bano. En otras realizaciones, el detector también determina la composición del bano, incluyendo la relación de criolita del bano y la concentración de alúmina.
