Problems solved by technology
[0004] Although the hot-dip galvanized coating is thick, the thickness is uneven. The coating of the hot-dip galvanized wire in the prior art is very rough, and the molten zinc liquid in the galvanizing process is easy to form tough colloidal oxides, which adhere to the on the wire and form a highly irregular coating surface
This rough coating cannot meet the needs of the market

Embodiment Construction
[0025] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0026] like figure 1 As shown, the processing system of the galvanized wire of the present invention comprises a pay-off roller 1, a heater 2, a flux tank 3, a galvanizing tank 4, a leveling pipe 9, a sizing pipe 5, a forced cooling unit 6 and a collection Wire roller 7, the described pay-off roller releases the wire at a constant speed by rotation and drives the wire into the heater; the heater is used to heat the wire to a predetermined temperature; There is a plating aid, and the metal wire heated to a predetermined temperature is dipped in the plating aid in the plating aid tank; the zinc bath in molten state is arranged in the described galvanizing tank, and the metal wire dipped in the plating aid is galvanized Zinc layer is plated in the tank; the leveling tube is vertically arranged above the galvanizing tank, the bottom of th...

The invention discloses a processing system and process of a galvanized wire. The processing system comprises an unwinding roller, a heater, a plating assistant tank, a galvanizing tank, a leveling tube, a sizing tube, a forcing cooling part and a winding roller; the heater is used for heating a metal wire to the predetermined temperature; the metal wire heated to the predetermined temperature isdipped with a plating assistant in the plating assistant tank; the metal wire dipped with the plating assistant is plated with a zinc layer in the galvanizing tank; an opening is formed in the bottomof the leveling tube, inert gas is introduced into the leveling tube and sprayed towards molten zinc liquid in the galvanizing tank through the opening, and an oxide on the surface of the zinc liquidis blown away, so that the metal wire is prevented from making contact with the oxide on the surface of the zinc liquid; when the metal wire plated with the zinc layer passes through the interior of the sizing tube, the excessive plating layer on the outer circumferential wall of the metal wire is scraped through the sizing tube; the forcing cooling part is used for forcibly cooling the metal wireplated with the zinc layer to the room temperature; and the winding roller is arranged above the forcing cooling part and used for winding the galvanized wire cooled to the room temperature onto thewinding roller by rotation.
Description
technical field [0001] The invention relates to the technical field of galvanized wire processing, in particular to a galvanized wire processing system and a processing technology thereof. Background technique [0002] Galvanized wire is widely used in various fields such as construction, handicrafts, weaving wire mesh, highway guardrails, product packaging and daily civilian use. [0003] Galvanized wire is divided into hot-dip galvanized wire and cold-dip galvanized wire (electro-galvanized wire). Hot-dip galvanizing is dip-plating in a heated and melted zinc solution; cold-dip galvanizing (electro-galvanizing) is a one-way current in the electroplating tank to gradually coat the zinc on the metal surface. The production speed of cold galvanizing (electro-galvanizing) is slow, the coating is uniform, the thickness is relatively thin, usually only 3-15 microns, the appearance is bright, and the corrosion resistance is poor. Generally, it will rust in a few months. Hot-dip...
