Abstract

Procédé pour former un gateau filtrant pour filtrer un métal liquide au moyen de particules (9) stables dans le métal liquide sur un substrat inerte (8) perméable au métal liquide dans le trajet d'écoulement du métal liquide à filtrer, suivant lequel on dépose les particules (9) dans le trajet d'écoulement à l'amont du substrat (8) pour qu'elles soient entrainées au moins partiellement par l'écoulement du métal et dispersées à l'état de gateau filtrant prémouillé et pré-amorcé sur le substrat (8).
