GALVANIZING
Galvanizing is a process for rustproofing iron and steel by the application of a zinc coating. Three of the most-used processes for applying zinc to iron and steel are hot-dip galvanizing, electrogalvanizing, and zinc spraying. Most products are coated using the hot-dip process. It involves immersing steel into a bath of molten zinc,

Non‐linear optimal control for the hot‐steel rolling mill system
The aim of the hot strip finishing mill process is to roll transfer bars, produced in a rough milling process (around 30 mm thick), into steel strips of variable thickness (between 0.8 and 20 mm) [, ]. The reduction of the thickness is achieved by moving the metal strips through rolling strands where pressure is exerted [-].
