STUDY OF ALUMINUM MELT REFINING PROCESS EFFICIENCY DEPENDING ON IMPELLER WEAR
Original language description
The Foundry Degassing Unit for aluminum melt refining uses graphite components which, due to the action of the melt, degrade and lose their original shape. The shape of the impeller can have a significant effect on the efficiency of refining. This paper presents the study of the aluminum melt refining process efficiency depending on the degree of impeller wear. Operational experiments were performed to map degassing efficiency in defined phases of the impeller life. The efficiency was assessed by the Dichte Index which represents the degree of degasification of the melt after refining. It turned out that the new impeller released moisture into the melt, resulting in reduced impeller efficiency. The impeller achieved more than 90% efficiency in the following stages of its life.
