Large coils of galvanized wire is formed through wire drawing, wire drawing is a kind of processing technology, can make the product to achieve the required shape and meet the standard mechanical properties. Cold drawing is drawn at the recrystallization temperature, hot drawing is drawn at the crystallization temperature, warm drawing is drawn at above room temperature but below the crystallization temperature. Cold drawing is a common drawing method. Hot drawing is the heating of the metal wire before it enters the die hole. It is mainly used for drawing the metal wire with high melting point.
Warm drawing is to be heated by the heater to the specified range of temperature, mainly used for galvanized, difficult to deformation of steel wire drawing. Galvanized wire is processed through the drawing process, the formation of standard specifications of steel wire, and then in the electroplating tank through the current unidirectional zinc plating surface. The production speed is very slow, the zinc layer of zinc plating is very uniform, the thickness is relatively thin, generally in 3~15 microns, the brightness is very high, but relatively poor corrosion resistance, when using it is recommended to buy according to the demand.
Large coils of galvanized wire products are widely used for its rust and corrosion resistance, because zinc has a great protective effect on the appearance of the product, so it greatly improves the role and characteristics of the product itself, which also promotes the promotion of the application of the product. The zinc layer of zinc wire with thick zinc layer has fine crystallinity, uniform and no gap, and good corrosion resistance.
The zinc layer obtained by electrogalvanizing is very pure and corrodes slowly in the gas, liquid and fog of acid and alkali, which can effectively protect the steel base. Galvanized layer can also be chromic acid passivation treatment into a variety of colors, beautiful and generous, has a good decorative. The zinc layer on the galvanized wire has good ductility, can be cold stamping, rolling, bending and other forming without damage to the zinc layer.
