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.
