Abstract

La presente invención se refiere a filtro cerámico para filtrar metales fundidos, con estructura de espuma de celdas abiertas, a base de cerámica de alto punto de fusión, el cual comprende dos superficies de circulación opuestas, que se extienden transversalmente a la dirección de circulación del metal fundido que se va a filtrar y al menos una superficie lateral que se extiende sustancialmente en la dirección de circulación; caracterizado porque la superficie o superficies laterales están provistas en conjunto, en dirección periférica, de una capa cerrada de material refractario con una profundidad de 0.5 a 3mm y las almas libres de las celdas de la estructura de espuma presentes en las superficies de circulación están cerradas por un revestimiento de material refractario.The present invention refers to a ceramic filter for filtering molten metals, with an open cell foam structure, based on a high melting point ceramic, which comprises two opposite circulation surfaces, which extend transversely to the circulation direction of the molten metal to be filtered and at least one side surface extending substantially in the direction of flow; characterized in that the surface or lateral surfaces are provided as a whole, in the peripheral direction, with a closed layer of refractory material with a depth of 0.5 to 3mm and the free cores of the cells of the foam structure present on the circulation surfaces are closed by a lining of refractory material.
