Definitions

  • the invention relates to a device for hot-dip coating a metal strip and a method for hot-dip coating a metal strip.
  • Conventional coil coating systems such as systems for the continuous hot-dip galvanizing of steel strip, have in particular a continuous furnace, a molten bath (zinc bath), a device for adjusting the (zinc) coating thickness and a subsequent cooling device in the belt running direction.
  • the steel strip is heat-treated in the continuous process, the continuous furnace being able to be divided into several chambers in which different treatments, in particular in connection with different temperatures, can be carried out.
  • These treatments can preferably include the setting of the desired mechanical properties in the steel strip base material by, for example, recrystallization of the steel structure.
  • An area (chamber) in the continuous furnace can define a zone for reducing the iron oxides formed on the surface of the steel strip.
  • Another area (chamber) can define a cooling zone in the continuous furnace, in which the steel strip is cooled, preferably under protective gas (HNX), to a temperature close to the temperature of the melting bath.
  • the protective gas is intended to prevent the annealed strip from oxidizing prior to coating (galvanizing), as a result of which wetting and thus adhesion of the coating or coating (zinc layer) to the surface of the steel strip would not be possible, or would be possible only with difficulty, and thus the required quality requirements cannot be met. Because of the different treatments in particular, different gas atmospheres are therefore sometimes required in the areas (chambers) in the continuous furnace.
  • the steel strip is carried out between the continuous furnace and the melting bath, excluding the ambient atmosphere, in a lock flooded with protective gas, which is also referred to in the trade as a proboscis.
  • devices are used within the proboscis which cause circulation of the atmosphere inside the proboscis by targeted blowing in at one or more points. combined with suction at one or more points to remove or remove the dusty atmosphere.
  • the blow-suction -Unit has a plurality of injection openings for applying protective gas to the steel strip, wherein a plurality of injection openings are arranged or can be arranged on a first side of the steel strip and a plurality of injection openings on a second side of the steel strip, the blow-suction unit having a plurality of suction openings for suction of protective gas loaded with zinc vapor and / or zinc dust, wherein a plurality of suction openings on the first side of the steel strip and a plurality of suction openings on the second side of the steel strip are arranged or can be arranged, wherein the blow-suction unit has a blow-in area in which
  • the arrangement of the blow-suction unit within the trunk leads to a reduction in the flow cross section of the steel strip, so that in the event of vibrations and / or fluctuating operating conditions in the strip galvanizing system, the strip does not prevent the strip from vibrating out of the plane of the strip running direction during operation, and thus Even contact with the blow-suction unit cannot be ruled out, causing damage to the belt and can also arise in the system.
  • the invention is based on the object of providing a device and a method for hot-dip coating a metal strip, with which or with which an operationally reliable coating process can be ensured in the event of fluctuating operating conditions.

  • the slot openings can be optimally used, since in particular the beam expansion occurring in the gas streams emerging from adjacent slot openings does not influence one another (negatively) and a closed gas curtain can thereby form. Due to the staggered arrangement of the slot openings in a blowing unit with respect to the slot openings or interruptions of the blowing unit provided on the opposite wall, a denser layer is also formed in the outer areas of the trunk, which are not traversed by the metal strip and in which the injected gas flows meet gas curtain.

  • the smaller dimension of the The slot opening of the blowing unit is intended to produce a certain impulse in connection with a circulation of the atmosphere inside the trunk, whereby the larger size of the slot opening of the suction unit is to ensure that the metal vapor and / or metal dust is removed without clogging or clogging the slot opening (s) ) can be avoided, thereby extending the maintenance intervals, in particular for cleaning purposes.
