摘要： The invention relates to a device for hot-dip coating a metal strip, comprising a molten bath vessel (4), a pipe (6) which opens into the molten bath vessel for introducing a metal strip that has been heated in a continuous furnace (1) into said molten bath and a deflection roller (7) arranged in the molten bath for deflecting the metal strip (1) entering the molten bath in a direction leading out of said molten bath. According to the invention, the pipe (6) is provided with a chute-type pipe extension piece (6.1) for increasing the submersion depth of the pipe and the inner width of the pipe extension piece (6.1) tapers towards the outlet opening of the piece (6.15), at least over part of the length of said piece. This increases or maximises the turbulent flow in the melt on or in the vicinity of the metal strip (1), thus achieving the improved homogenisation of the melt in the region of the strip and thereby allowing the prevention of slag-related surface defects on the surface of the coated metal strip (1).

摘要： The present invention relates to a method for producing a component from a steel product coated with an Al-Si protective coating, and to an intermediate product, which is generated in the course of such a method and can be used for the production of components of the type in question. In the course of the method, the steel product coated with the Al-Si coating is subjected to a first heating step, wherein the temperature and the duration of the heat treatment are set such that the Al-Si coating is only partially pre-alloyed with Fe of the steel product, in a second heating step the steel product is heated to a heating temperature above the Ac1 temperature, the steel product at said heating temperature having an at least partially austenitic structure, wherein the temperature and duration of the second heating step are set such that the Al-Si coating in the course of the second heating step is completely alloyed with Fe of the steel product, the steel product heated to the heating temperature is shaped into the component, and the resulting component is cooled in a controlled manner in order to produce a hardness structure.
