  • Out-of-line annealing means that the recrystallization annealing of hot or cold rolled steel plate is carried out in the bottom type annealing furnace or cover type annealing furnace before entering the hot plating wire line, so that there is no annealing process in the galvanized line. The steel plate must maintain a clean active surface of pure iron, free of oxides and other dirt, before hot dip galvanizing. In this method, the annealed surface oxide sheet is first removed by pickling method, and then coated with a layer of zinc chloride or a mixture of ammonium chloride and zinc chloride solvent for protection, so as to prevent the plate from being oxidized again.

  • In addition, before the steel wire enters the zinc liquid, covered with a layer of insulation material containing zinc oxide reducing agent, can reduce the heat loss and zinc ash floating. In addition, adding zinc-5% aluminum-mixed rare earth alloy to the zinc solution, when the zinc solution contains 0.002%-0.005% aluminum mass fraction, can obviously increase the brightness of the zinc layer, and prevent the zinc solution surface oxidation caused by excessive zinc ash.
