Abstract (en)

[origin: WO9623222A1] A device for determining the purity of a metal alloy, in particular an aluminium alloy, It comprises a pot (10) featuring a receptacle (14) of an essentially flared shape on a vertical axis, the lower extremity featuring an orifice (18) of reduced dimensions, the entire orifice being blocked by a filter (20). The device also comprises means (26, 28) for bringing the pot initially to a first pre-set temperature, means for introducing a predetermined quantity of the alloy to be tested into the receptacle, said quantity of the alloy being at a second pre-set temperature, through wihich the alloy flows by gravity via the filter until the latter is clogged by the impurities in the alloy, and means (12) for collecting and measuring the volume of the alloy which has passed through the filter before it is clogged by the impurities in the alloy.
