Title (EN) FILTRATION APPARATUS AND METHOD OF CHARACTERISING MOLTEN MATERIALS
(FR) APPAREIL ET PROCEDE DE CARACTERISATION PAR FILTRATION DE MATERIAUX A L'ETAT FONDU
Abstract:
(EN) A method of charaterising molten materials comprising the steps of effecting flow of the material through means for filtering out inclusions within the material, monitoring the flow of the molten material through the filtering means, and comparing the measured flow with a predetermined flow characteristic to enable determination of the character of the material.
(FR) Procédé de caractérisation de matériaux à l'état fondu consistant à faire passer un écoulement du matériau dans un dispositif destiné à filtrer les inclusions que renferme ce matériau, à contrôler l'écoulement de matériau à l'état fondu traversant le dispositif de filtration, et à comparer l'écoulement mesuré à un écoulement prédéterminé caractéristique afin de pouvoir déterminer la nature du matériau.
