Description

technical field [0001] The invention relates to a method for coating the surface of a metal strip. The invention also relates to a corresponding metal strip coating device. Furthermore, the invention relates to a computer product as well as to a use of a metal strip device and a use of a thermal imaging camera. Background technique [0002] Usually the metal strip is coated in order to be able to achieve the desired functionality especially on the surface of the metal strip. Different pretreatment methods are used depending on the type, properties and desired functionality of the surface. Commonly important desired goals of surface treatment are the cleaning of the surface to be coated, the provision of corrosion protection of the surface, optimal adhesion between the surface and subsequent coatings and, for example, the provision of other functional coatings of the surface. [0003] The increasing demands placed on the metal strip, as well as the mechanical and thermodyn...

AI Technical Summary

Problems solved by technology

Although a continuous detection during the metal strip coating process is achieved, the disadvantages of the described method are, on the one hand, the relatively complex evaluation of the measured spectra required by the method and, on the other hand, the limitation of the selected spectrum type coverage area

However, the methods described are expensive due to the processes required for active heating and thus do not allow or in most cases require an uninterrupted inspection of the surface quality of the coated surface at great expense
