Abstract:
1. A process for producing a coated metal strip from a semi-finished strip, which comprises the steps of: providing a coil of a cold-rolled strip obtained by cold rolling, cooling and recrystallization annealing; unwinding the cold-rolled strip off of the coil; applying a medium having metallic particles to the cold-rolled strip for forming a corrosion protection layer resulting in a coated semi-finished strip, the medium being a wet-chemical solution applied by one of spraying, dipping, squirting, flooding or rolling; drying the corrosion protection layer on the cold-rolled strip by supplying heat at a temperature being below a recrystallization annealing temperature of the cold-rolled strip after application of the medium and before performing a winding up step; and performing the winding up of the coated semi-finished strip to form a further coil.
