The invention concerns a method for filtering a metal liquid by passing said metal liquid on a bed of refractory particulate material characterised in that the particulate material, generally based on electrically melted corundum has an open porosity between 5 and 30 %. The invention (B) enables to use reduced retention times (T) while maintaining a quality level at least equal, even higher, than that obtained with other particulate materials (A).
Procédé de filtration de métal liquide par passage dudit métal liquide sur un lit de matériau particulaire réfractaire caractérisé en ce que le matériau particulaire, généralement à base de corindon électrofondu, a une porosité ouverte comprise entre 5 et 30%. L'invention (B) permet d'employer des temps de séjour (T) réduits tout en maintenant un niveau de qualité au moins égal, voire supérieur, à celui observé avec d'autres matériaux particulaires (A).
