Abstract

Procedimiento e instalación para la filtración de metal fundido; sobre todo de aluminio o de aleaciones de aluminio, caracterizados porque: - dentro de un tubo para el metal fundido, dispuesto por delante del molde de fundición, está situado por lo menos un elemento de filtración de tipo desmontable de material de espuma cerámica, y que - el metal fundido pasa por el filtro, formado por, como mínimo, un solo elemento filtrante, con una velocidad tal que resultan separadas todas las partes arrastradas de películas de óxido y de partículas, originándose detrás de éste filtro una corriente de metal fundido tranquila y exenta de turbulencias.
