  • 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.

  • Cold galvanizing, also called electric galvanizing, is the use of electrolytic equipment to remove oil, pickling, after the pipe fitting into the composition of zinc salt solution, and connected to the negative electrode of the electrolytic equipment. Wire factory on the opposite side of the pipe fittings placed zinc plate, connected to the positive electrode of the electrolytic equipment is connected to the power supply, the use of current from the positive electrode to the negative electrode will deposit a layer of zinc on the pipe fittings, cold plating pipe fittings is first processed after galvanized.

  • The electrode is a kind of material that the coating (that is, the coating) is uniformly and centrally applied on the welding core outside the metal welding core. The electrode is composed of two parts: the welding core and the coating. The welding core is the metal core of the electrode. In order to ensure the quality and performance of the weld, there are strict regulations on the content of various metal elements in the welding core.
