Abstract

Dross growing on immersed rolls is responsible for defects on thegalvanised strip. It is essential to identify the mechanism of thisaccumulation on immersed hardware. An industrial approach hasbeen followed: stainless steel samples (316L) were set up at severallocations on the moving rolls and on the static members through agalvanising campaign. The samples were then analysed by means ofoptical and electron microscopy. The results from this first approachpointed out significant effects of some factors referred to as “location” and “moving”. Further investigations, including a deeper analysisof several parameters, are requested to validate the proposedmechanisms.
