Abstract
Zinc-coated steel sheets have high efficiency in corrosion resistance. The most common processes in the industry to obtain this coating are hot-dip galvanizing, thermal spraying, and electrodeposition. During this process, certain parameters can lead to the formation of intermetallics know as dross particles (Zn-Al-Fe), that have harmful effects on the final coated products. This work aims to study possible dross formation in steel sheets with coated surfaces in a hot-dip galvanizing continuous line through fluid dynamics analysis. A simulation using the OpenFOAM software is employed for the study of the fluid dynamic conditions of the process, addressing particularly the flow conditions and particle trajectories in the snout.
