Abstract

Cincel perfeccionado para los dispositivos de rotura de costra de electrolito sólido de una cuba electrolítica, en particular las cubas para la producción de aluminio, caracterizado porque por lo menos partes de las regiones del borde de la cara del fondo del mismo se proyectan más allá de las otras regiones y están conformadas como bordes cortantes, y tal que la cara del fondo del cincel no presenta área alguna que está inclinada hacia fuera y pueda crear fuerzas actuantes hacia el exterior al impulsar el cincel a través de la costra.
