The invention relates to a method for hot dip galvanizing hot rolled steel strip and to a hot rolled strip galvanizing installation. In a first method step, the strip (50) to be galvanized is introduced into a pickling station (10) inside of which the layer of scale as well as reaction products are removed from the surface of the strip. In a subsequent working step, the strip (50) is introduced into a rinsing station (20) in which residual pickle and pickle products are removed from the surface of the strip. Afterwards, the strip (50) is introduced into a drying station (30) and dried therein. From there, the strip (50) is introduced, in another method step, into a furnace (40) in which it is heated, under a protective gas atmosphere, up to a galvanizing temperature. In a final method step, the strip is guided through a galvanizing bath in which it is coated with a hot dip galvanizing layer. This method is improved in such a way that the strip (50) is heated in the furnace (40) to a temperature that does not exceed the bath dipping temperature in the zinc bath by more than 50 DEG K.
