摘要

Method for the fabrication of a steel product comprising a step of characterization of a layer of oxides (22) present on a running steel substrate (21), the characterization comprising the steps of: - providing a portion of the steel substrate comprising a layer of oxides wherein the portion defines an oxide surface, - collecting light (Lr) from said oxide surface using a hyperspectral camera (20) in order to obtain intensity values (I
