Abstract

Metode for bestemmelse av aluminium i slagg fra slaggkilder såsom en støperiovn, holdeovn, elektrolyseovn eller smeltebehandlingsenhet. Metoden er basert på at det ved måling av tetthet og vektandel ren aluminium i slaggprøver fra hver enkel slaggkilde etableres et lineært forhold mellom tetthet og ren aluminium basert på formelen m = kg> + a, der "m" er mengden ren aluminium, "g" er slaggets tetthet og "k" og "a" er konstanter knyttet til måleresultatenes beskaffenhet/spredning, hvorved det etablerte lineære forholdet ved senere målinger av tetthet av slaggprøver alene gjør det mulig å bestemme vektandelen av aluminiummetall i prøvene.Method of determining aluminum in slag from slag sources such as a casting furnace, holding furnace, electrolysis furnace or melting unit. The method is based on the fact that when measuring density and weight of pure aluminum in slag samples from each individual source of slag, a linear relationship between density and pure aluminum is established based on the formula m = kg> + a, where "m" is the amount of pure aluminum, "g "is the density of the slag and" k "and" a "are constants related to the nature / spread of the measurement results, whereby the established linear relationship in subsequent measurements of the density of slag samples alone makes it possible to determine the weight ratio of aluminum metal in the samples.
