Abstract
Sistema de aspiración para reducir las pérdidas de materiales de textura fina y de polvos de un horno de arco eléctrico (11) que tiene una solera inferior (12) adecuada para contener el baño metálico de material metálico en proceso de fusión (13), una cuba sustancialmente cilíndrica (14) dispuesta por encima de la solera (12), por lo menos un electrodo (15) dispuesto en una zona central de la cuba (14), una bóveda (16) dispuesta para cubrir la cuba (14) y provista de por lo menos una apertura (18) a través de la cual los humos producidos por el baño metálico pueden salir, por lo menos un primer subsistema de aspiración (20) y por lo menos otro subsistema de descarga (21, 22) dispuesto en correspondencia con la bóveda (16), estando caracterizado dicho sistema porque dicho primer subsistema de aspiración (20) está dispuesto dentro de la cuba (14) y comprende un serpentín de tubos de refrigeración (24) dispuestos helicoidalmente para definir, en una dirección vertical, zonas vacías (26) entrelas espirales de los tubos, estando el serpentín de tubos de refrigeración (24) distanciado de la pared cilíndrica de la cuba (14) para definir un interespacio periférico (25) a través del cual los humos pueden ascender hacia la bóveda (16) según por lo menos un torbellino rotatorio ascensional.
