Galvanized wire product knowledge can be introduced in detail from the following aspects:
1. Definition and Overview
Galvanized wire, as the name suggests, is a metal wire covered with a zinc layer. This wire through the galvanizing process, forming a layer of zinc on the surface of steel and other metals, thereby improving the corrosion resistance and service life of the wire. Galvanized wire is widely used in construction, electricity, transportation and other fields, is an indispensable material in industrial production and daily life.
2. Characteristics
1. Corrosion resistance: The galvanized layer can effectively isolate the contact between the metal matrix and the external environment, significantly reducing the risk of rust, thereby extending the service life of the wire.
2. Electrical conductivity: Galvanized treatment does not affect the electrical conductivity of metal wire, so that it has a wide range of applications in the field of power and communication.
3. High strength: Galvanized wire retains the strength characteristics of the original metal wire, and can withstand greater tension and pressure.
4. Aesthetics: Galvanized wire surface gloss is high, beautiful appearance, can improve the added value of products.
3. Classification
Galvanized line according to the different production process, mainly divided into hot galvanizing line and cold galvanizing line (electric galvanizing line) two kinds:
Hot dip galvanized wire : By dipping the wire into the molten zinc liquid, the zinc layer is closely combined with the surface of the wire, the production speed is fast, the coating is thick but not uniform, the corrosion resistance is good, but the appearance color is darker, and the zinc metal is consumed.
Cold galvanizing wire (electric galvanizing wire) : The zinc is gradually plated on the metal surface through the current unidirectionally in the plating tank, the production speed is slow, the coating is uniform and thin, the appearance is bright, but the corrosion resistance is relatively poor.
4. Application field
1. Construction field : Galvanized wire in the construction field is mainly used for binding steel bars, fixed scaffolding, etc., its corrosion resistance makes the building more safe and reliable. At the same time, galvanized wire is also used for the manufacture and reinforcement of steel structures, such as steel bars, steel pipes, steel plates, etc., to improve the service life of buildings.
2. Power industry : Because galvanized wire has good electrical conductivity and corrosion resistance, it is widely used in power transmission lines, transformers and other power equipment.
3. Transportation field : Galvanized wire is also widely used in the field of transportation, such as the overhead contact line in the railway track, signal cables, etc. Galvanized wire is needed, and its excellent electrical conductivity and corrosion resistance can ensure the normal operation of traffic facilities.
4. Communication field : Galvanized wire is also commonly used in the production of communication cables to ensure the stability and reliability of signal transmission.
5. Other fields : Galvanized wire is also widely used in handicrafts, wire mesh, highway guardrail, product packaging and daily civilian fields.
5. Production process
The production process of galvanized wire mainly includes the following steps:
1. Raw material preparation: Choose high-quality low carbon steel wire rod as raw material.
2. Drawing forming: The raw steel wire rod is drawn into the required diameter of the wire.
3. Pickling: Remove rust and impurities on the surface of the wire by pickling.
4. High temperature annealing: improve the toughness and processability of wire.
5. Galvanizing treatment: According to the different production process, choose hot dip galvanizing or cold galvanizing (electric galvanizing) to coat a layer of zinc on the surface of the wire.
6. Cooling and subsequent treatment: The galvanized wire is cooled and the necessary subsequent treatment, such as passivation, oiling, etc., to improve the corrosion resistance and beauty of the product.
In summary, galvanized wire with its excellent corrosion resistance, electrical conductivity and high strength characteristics, plays an important role in many fields such as construction, power, transportation and so on. By understanding its properties and production processes, we can better understand and apply this important industrial material.
