Abstract
A method for hot dip galvanizing of hot-rolled steel strip, wherein in a first method step, the strip ( ) is introduced into a pickling station ( ) and a layer of scale and reaction products are removed from the strip surface in the pickling station. In another method step, the strip ( ) is introduced into a rinsing station ( ) and residues of the pickle and pickling products are removed from the strip surface in the rinsing station, and subsequently the strip is introduced into a drying station and is dried. And from there, in another method step, the strip is introduced into a furnace ( ) and is adjusted to galvanizing temperature under a protective gas atmosphere. In a last method step, the strip is guided through a galvanizing bath and the surface of the ( ) is coated with a hot dip galvanizing layer in the galvanizing bath, wherein the strip temperature in the furnace ( ) is adjusted at most to 50° K. above immersion temperature of the strip ( ) into the zinc bath.
