Method for lowering the coefficient of friction of the surface of metal bands with a coating and device for applying a metallic coating onto a steel band

摘要

The present invention relates to a method for lowering the coefficient of friction of the surface of the steel band (S) to the metal band coating, in particular tin plating or chromium plating, or being passed through the coating equipment at a predetermined band speed (v). In order to allow the metal band coated to reduce the coefficient of friction of the coated surface, even when passing through the coating plant with the band speed of the high speed, according to the present invention, the top-coated metal band through a band speed (v) after the coating process the aqueous tensides (tenside) are sprayed. The invention also relates to device and also for applying a steel band, in particular a metal coating over the band or band tin plating equipment chromium plating equipment. ; Metal bands, coatings, tensides aqueous solution, the coefficient of friction, tin plating, chromium plating, the amount of iron,
