Title (EN) FILTRATION DEVICE FOR FILTERING MOLTEN METAL
(FR) DISPOSITIF DE FILTRATION POUR METAL FONDU
Abstract:
(EN) A filtration device for filtering molten metal comprising a body defining a cavity for receiving molten metal, an outlet for the molten metal from the body, and means for holding a filter between the cavity and outlet for concentrating inclusions in the metal in the cavity, characterised in that the body comprises refractory fibrous material. Use of such a filtration device enables the rapid melting of a solid metal sample in the device to form a representative liquid metal sample which can then be filtered.
(FR) La présente invention concerne un appareil de filtration destiné à filtrer le métal en fusion. Ce dispositif est constitué d'un corps définissant une cavité de réception du métal en fusion, d'un orifice de sortie pour le métal en fusion provenant du corps, et d'un dispositif de retenue de filtre entre la cavité et l'orifice. La fonction du filtre est de concentrer dans la cavité les inclusions se trouvant dans le métal. Le corps est caractérisé en ce qu'il comporte un matériau réfractaire fibreux. L'utilisation d'un tel appareil de filtration permet de faire fondre rapidement dans le dispositif un échantillon de métal solide pour constituer un échantillon représentatif du métal liquide qui peut alors être filtré.
