Embodiment 1

[0064] The product produced in this embodiment is a galvanized steel wire: the steel wire after the drawing is successively passed through the degreasing device, the washing device, the pickling tank device, the washing device, the plating aid device, etc., which are improved by the present invention, and the steel wire is degreased, washed, After pickling, water washing, and plating help, enter the hot-plating device with induction heating coil in the present invention, carry out fast induction heating (150~200 ℃) to steel wire, then pass through and load pure zinc (wt%Zn≧99%) The working pool (zinc liquid temperature 450-480 ℃), the pressure value at the upper end of the working pool is adjusted through the pressure control valve 3 during the working process, so that the zinc liquid level is higher than the two sides by a certain height through the hole, and then passes through the other side Lead out through the hole, use annular air knife (nitrogen at 200-300°C) for air kni...

Embodiment 2

[0066] The product produced in this embodiment is a hot-dip Galfan alloy steel wire, and the steel wire after the drawing is successively passed through the degreasing device, washing device, pickling tank device, water washing device, plating aid device, etc., which are improved and obtained by the present invention, to degrease the steel wire, After water washing, pickling, water washing, and plating help, enter the horizontal hot-plating device with induction heating coil described in the present invention again, carry out fast induction heating (150~200 ℃) to steel wire, pass through loading Galfan (Zn- 5wt%Al-Re) working pool (the temperature of the zinc liquid is 450-480°C, the pressure value at the upper end of the working pool is adjusted during the working process so that the Galfan alloy liquid level is higher than the two sides through the hole to a certain height), and then through another One side is led out through the hole, and an annular air knife (nitrogen at 2...

Embodiment 3

[0068]The product that the embodiment of the present invention produces is Φ 10 galvanized round steel (galvanized disc circle), adopts steel brush machine to carry out steel brush derusting by the wire rod that rolling obtains, removes the ups and downs of reinforcing bar surface through air knife purging then, and then The steel bar after derusting is introduced through the centering wheel, passes through the hot-plating device of the present invention, starts the induction heating coil to carry out high-frequency induction heating (600~800 ℃) to the steel bar under nitrogen protection, then passes through the working pool (wt%) Zn≧99%, pressure control and adjustment are the same as in Example 1), after being purged by an air knife, enter the water cooling device and passivation device for water cooling and passivation, and finally cut, pack, and store, and the horizontal hot-dip galvanized round steel production.

Abstract

The invention relates to a long material processing device and a hot dipping production line and a hot dipping method based on the same, the processing device comprises a working pool and a supply pool, the lower parts of the working pool and the supply pool are communicated, the upper part of the working pool is closed, the upper part of the supply pool is communicated with the atmosphere, and the upper parts of the working pool and the supply pool are provided with penetrating holes at the same height for long materials to enter and exit; all the penetrating holes are connected together through quartz pipe fittings in sequence to form a channel for long materials to pass through; treatment liquid is added into the working pool and the supply pool, and the liquid level of the working pool is higher than the position where the upper end of the penetrating hole is located. The working pool of the treatment device is of a closed structure, so that the long material hot dipping production process is more energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of metal coating, and in particular relates to a long product processing device, a hot-dip production line and a hot-dip method based on the device. Background technique [0002] At present, the galvanizing of long products adopts the solvent method, and the galvanizing process is: wire setting→alkali washing→water washing→acid washing→water washing→plating help→drying→galvanizing→leading→water cooling→passivation, solvent method galvanizing The biggest defect is the environmental problems caused by the production process, such as the discharge of waste acid, waste water, and waste gas; almost most of the production workshops use open liquid storage tanks, and the workshop environment is relatively harsh due to pollution such as acid mist and dust. Moreover, the galvanizing process generally involves the use of annealing furnaces, drying furnaces and other devices, and the amount of molten zinc in the zinc p...
