Abstract
Zinc-coated steel sheets have high efficiency in corrosion resistance - and Hot Dip Galvanizing is one of the most used industrial methods for obtaining this type of coating. Certain factors can cause the development of intermetallics known as dross particles (Zn-Al-Fe) during this process, which can affect the final coated processes. Through fluid dynamics research, this project intends to investigate possible dross production in steel sheets with coated surfaces in a continuous hot-dip galvanizing line. The fluid dynamic characteristics of the process were studied using the gridap.jl library, written in Julia programming language, with particular attention paid to flow conditions and dross particle paths in the snout. Results of simulations show that changes in operational parameters like the strip speed, snout inclination, bath temperature and composition, affect dross particles density and distribution in the bath, thus affecting the final quality of the material.
