APPARATUS FOR THE CONTINUOUS HOT-DIP COATING OF METAL STRIP

摘要

The invention relates to a device for the continuous galvanizing of metal strip (5), preferably steel strip, comprising a molten bath container (2), a nozzle (6) opening into the molten bath container for introducing a metal strip (5)that is heated in a continuous furnace into the molten bath (1) under shielding gas, and a deflection roller (3) arranged in the molten bath container for deflecting the metal strip (5) entering into the molten bath (1) in a direction pointing out of the molten bath, wherein the nozzle (6) comprises in the end thereof that is dipped into the molten bath at least one discharge chamber (11), which is inwardly delimited by an overflow wall (8), downwardly by a bottom (23, 24, 24.1, 24.2) and outwardly by the wall of the nozzle (6), wherein the overflow edge (9, 10) of the overflow wall (8) is located at least in sections below the molten bath level (S) and wherein a suction line (12) comprising a pump (13) is connected to the discharge chamber (11), characterized in that the discharge chamber (11) is provided at least with one through-opening (14, 15), through which liquid molten metal can flow from the molten bath (1) into the discharge chamber (11), wherein the at least one through-opening is arranged lower than the overflow edge (9, 10).
