Among the parameters involved in the production of aluminium alloys, a particularly demanding in terms of regulation are those involved in dross skimming. To reduce aluminium losses and maintain the uniform quality of skimming, the skimming depth (dross removal) should be limited, as much as possible, to near the interface between the dross layer and the molten metal.
The purpose of this work was the development of an automatic skimming procedure. The position of the skimming spoon was guided by a continuous measurement of the temperature gradient across the dross layer, with thermocouples positioned on its bottom edge. The efficiency of this novel procedure was validated by continuous tracing of the specific amount of skimmed dross (SASD), recognized as a valuable quantitative indicator of the quality and the efficiency of the melting procedure as well as of the quality of the molten metal produced.
