Method and apparatus for producing fine or galvanized black plate with high corrosion resistance as well as use of the fine or galvanized Feinstblechs

The invention relates to a method for producing galvanized fine or blackplate with high corrosion resistance of a hot-rolled steel strip comprising the steps of: - plating the steel strip (1) with zinc, - temper rolling of the zinc-coated surface of the steel strip (1), one or both sides applying a polymer coating, or an organic coating on the zinc-coated surface of the steel strip (1) -. The invention further relates to an apparatus for performing the method with a transport means (7) for continuously transporting a continuous steel strip (1), a cold rolling device (6) for the cold rolling of the moving steel strip (1) to a thickness of less than 1 mm, a coating device (11) for the galvanic coating of the steel strip (1) with zinc, a rolling device (5) with temper rolling (5a) for temper rolling the galvanized surface of the steel strip (1), a heater (4) for heating the steel strip (1) and a plastic coating means (8) for unilateral or bilateral application of a polymer coating, or an organic coating on the zinc-coated surface of the steel strip (1).
