Abstract

Le filtre céramique à structure alvéolaire à cellules ouvertes à base de céramique à point de fusion élevé destiné à la filtration des métaux en fusion comporte deux surfaces d'écoulement transversales à la direction d'écoulement du métal en fusion. Les surfaces latérales 2 sont munies dans la direction circonférentielles, toutes ensembles, d'une couche fermée 5 en matériau réfractaire et présentant une profondeur comprise entre 0,5 et 3 mm. Application à la filtration des bains de fusion de métaux liquides tombant sous une hauteur importante ou devant traverser le filtre sous une pression élevée.The open cell ceramic filter with a high melting point ceramic cell structure for the filtration of molten metals has two flow surfaces transverse to the flow direction of the molten metal. The lateral surfaces 2 are provided in the circumferential direction, all together, with a closed layer 5 of refractory material and having a depth of between 0.5 and 3 mm. Application to the filtration of liquid metal melting baths falling under a significant height or having to pass through the filter under high pressure.
