Hot-dip galvanized wire is made of carbon structural steel, which is processed by drawing and hot-dip galvanizing. It is widely used in the manufacture of wire mesh, highway guardrail and construction engineering. Electrogalvanized wire is a metal conforming material made of low carbon steel as core wire and processed by wire drawing and electrogalvanizing. Mainly used in wire mesh, highway guardrail and construction projects.
The electrogalvanizing wire is made of medium and low carbon steel wire rod, which has the characteristics of good surface gloss, uniform zinc layer, strong adhesion and durable corrosion resistance. Can produce: diameter 1.60mm-4mm (16#-33#) cold plating wire; Diameter 6.40mm-0.81mm(8#-21#) black wire, modified wire. Mainly used in communication equipment, medical equipment and woven nets, brushes, steel cables, filters, high-pressure pipes, construction, crafts and other industries.
Its wire diameter specifications include: 8#-24#, with thick coating, strong corrosion resistance, solid coating and so on. And according to the special needs of users, according to industry standards to provide various specifications of galvanized wire. Low carbon steel wire is called galvanized fine iron wire after drawing and galvanizing, so that galvanized wire products have certain characteristics. In order to better make the galvanized wire play an effect, in the process of galvanizing, the thickness of the zinc layer of the galvanized wire is generally controlled according to customer needs, so that the galvanized wire can meet the needs of customers.
There are three methods to detect the thickness of the zinc layer of galvanized wire: weighing method, cross-section microscopy and magnetic method, of which the first two experiments will cause certain damage to the galvanized wire, including the length of the galvanized wire and the reduction of the amount. Generally, the detection of galvanized wire galvanized layer is detected by magnetic method, which is also a more intuitive and convenient method. The standard of galvanized layer thickness is related to the wire diameter of galvanized wire, the larger the wire diameter of galvanized wire, the thicker the galvanized layer, which is the thickness of the galvanized layer and the galvanized layer of cast iron after centrifugal separation.
The methods to control the thickness of galvanizing are as follows: you can slow down the lifting speed of the workpiece, control the galvanizing time as much as possible, add the appropriate amount of thinning alloy, reduce the thickness, and improve the zinc temperature of hot dip galvanizing. However, to consider the zinc pot situation, the iron pot should not exceed 480 degrees, and the ceramic pot can be 530 degrees, which can reduce the zinc dipping time.
