Abstract

Pantalla metálica de acero, destinada a impedir la infiltración del metal y de los constituyentes de baño de electrólisis en el revestimiento refractario y calorífugo del cajón de una cuba para la producción de aluminio por el procedimiento HALL-HEROULT, estando colocada esta pantalla bajo la base de los bloques que contienen carbono, que constituyen el cátodo de la cuba de electrólisis y en los cuales están empotradas las barras catódicas, y que se extienden al menos sobre todo el espacio situado en la vertical del cátodo, caracterizada porque esta constituida por al menos una chapa de acero continua en que al menos la mitad de la superficie está constituida por una parte que tiene al menos 5 mm, y de preferencia de 8 a 12 mm de grosor, y que comprende al menos una zona deformable que absorbe las solicitaciones debidas a las diferencias de temperatura entre la parte central, situada en la vertical del cátodo, y la parte periférica.
