FIELD: metallurgy.
SUBSTANCE: method includes a stage of immersing a moving sheet in a molten oxide bath having a viscosity between 0.3⋅10-3 Pa⋅s and 3⋅10-1 Pa⋅s, while the bath surface is in contact with non-oxidizing atmosphere, and the molten oxides are inert to iron. The residence time of the moving sheet in said bath is at least 1 s, and the residue of the oxides, remaining on the sheet surfaces at the outlet of the bath, are removed. A line for treatment of a ferroalloy sheet by this method is also proposed.
EFFECT: improvement of adhesion of a metal or metal alloy coating to steel sheets containing a significant amount of readily oxidizable elements.
