An apparatus for galvanizing which comprises a plating tank, a dross removing tank, a means to transfer the molten metal bath from the plating tank to the dross removing tank, and an opening located on the plating tank to recycle the molten metal bath from the dross removing tank to the plating tank.

Apparatus for hot dip galvanizing

The method for hot dip galvanizing comprises the steps of: dividing a plating vessel holding a molten metal into a plating tank and a dross removing tank; conducting hot dip galvanizing to a steel strip by immersing thereof in the molten metal bath; then transferring the molten metal bath from the plating tank to the dross removing tank; removing a dross from the molten metal bath in the dross removing tank; and recycling the molten metal bath from the dross removing tank to the plating tank through an opening located on the plating tank. The apparatus for galvanizing comprises a plating tank, a dross removing tank, a means to transfer the molten metal bath from the plating tank to the dross removing tank, and an opening located on the plating tank to recycle the molten metal bath from the dross removing tank to the plating tank.

Method for hot-dip galvanizing

An apparatus for hot-dip coating a steel strip, comprising: (a) an annealing furnace for continuously annealing the steel strip, the annealing furnace having an entrance side and an exit side; (b) a coating pot having a molten metal coating bath for coating the annealed steel strip; (c) a snout through which the annealed steel strip is introduced into the molten metal coating bath, one end of the snout being connected to the annealing furnace and the other end being immersed into the molten metal coating bath; (d) a seal device for sealing between the annealing furnace and the snout, the seal device being disposed at the exit side of the annealing furnace; and (e) a discharge device for discharging a gas containing a metal vapor from the snout to outside of the snout, the metal vapor being evaporated from the molten metal coating bath in the snout.

Apparatus for hot-dip coating a steel strip

A method for hot-dip coating a steel strip comprises: (a) continuously annealing the steel strip in an annealing furnace; (b) introducing the annealed steel strip into a molten metal coating bath through a snout; (c) dipping the annealed steel strip into the molten metal coating bath; (d) controlling a pressure inside of the snout; and (e) discharging a gas containing a metal vapor from the snout to outside of the snout. An apparatus comprises an annealing furnace, a coating pot, a control device for controlling a pressure inside the snout and a gas discharging device.
