The surface morphology of the galvanized sheets is formed after the solidification of the melted metal, carried along the carrier strap during its extraction from the zinc bath. The surface layer quality depends on the fluidity of the melting, on its

The method of autocatalytic reduction coating assures a precise reproduction of the coated surface. This is an advantage when the support surface has a complex geometry but also becomes a disadvantage because it requires a support without surface def

The excess of emulsion used in the lamination process leads to the formation of drops which in the annealing process forms spots of burned emulsion. It was also shown to cause formation areas with high carbon concentrations on the surface of the stee

In order to elucidate the morphology and mineralogy of the dust from blast furnace, the fundamental aspects of its generation process were studied. A dust generated by the dry dedusting step of the cleaning process for the BF off-gas was analysed by
