Abstract

The strength of the oxide skin on molten aluminum is important in many metal processing steps. Among others, it affects the surface finish of DC-cast ingots through the dynamics of the meniscus, feeding in low pressure die casting, and the yield of metal recovery when dross is processed.

This paper presents recent measurements of oxide skin strength on molten aluminum. The measurements were done on Al + 1%Mn and Al + 5%Mn, and are compared to earlier measurements on pure aluminum. Also the effect of a commercial salt mixture on the oxide skin strength on AlMn alloys is presented.
