Abstract

La presente invención se refiere a técnica de fusión eléctrica para carga vitrificable en la cual la energía se disipa por medio del efecto Joule en la masa fundida a partir de electrodos verticales sumergidos; la composición que se va a fundir está repartida en una capa uniforme en la superficie del baño, caracterizada en que los electrodos están dispuestos a distancia de las paredes refractarias del recipiente; la distancia que separa el electrodo de la pared lateral más cercana es de cuando menos la mitad de aquella que separa dos electrodos vecinos y la posición del nivel del máximo de tempertura está regulada por la profundidad de sumersión de los electrodos.
