Abstract:
A method for the hot-dip coating of metal strip, in particular steel strip, in a metallic melting bath (3) is disclosed. In the method, the metal strip (1) to be coated is heated in a continuous furnace (2) and is introduced into the melting bath (3) through a snout (6) which is connected to the continuous furnace and which is immersed into the melting bath. To be able to satisfy the requirements placed on the coated strip (1) with regard to good deformability of the strip, as far as possible without cracking and peeling, and with regard to high anti-corrosion protection in a more effective and reliable manner, the disclosure proposes that, in the region delimited by the snout (6), a melt is used which is intentionally implemented differently, in terms of its chemical composition, than the chemical composition of the melt used in the melting bath (3).
