  • The tensile strength of steel wire is high and the hardness is high. In the flattening process, the longitudinal movement resistance of steel wire per unit volume increases and the elongation decreases. The steel wire unit volume will move to the lateral resistance smaller, the width of the increase. On the contrary, the wire is easy to extend lengthwise, and its width decreases. This is the production of high steel wire hardness is easy to wide, small hardness, easy to stretch out of wide reasons. If the tensile strength deviation of steel wire is large, the hardness uniformity of steel wire strip is poor, the width difference of the billet rolled into large, will seriously affect the quality of the billet.

  • Especially after passivation of galvanized layer, the surface of the oxide layer is thicker and compact, itself has high oxidation resistance. On the other hand, when the surface of the galvanized layer is damaged, exposing the inner iron matrix, because zinc is more active than iron, zinc will bear the role of sacrificing zinc anode, zinc will be oxidized before iron, so as to protect the iron layer will not be damaged.

  • Secondly, galvanizing can increase the mechanical strength of the product. The wire drawing process is to draw metal materials to make their grains thinner, thereby improving the mechanical strength of the product. Galvanizing can form a layer of zinc on the surface of the product, and the zinc layer itself has a high hardness, which can provide additional support during the wire drawing process and prevent the metal material from tensile fracture during the wire drawing process. Therefore, galvanized products after wire drawing can increase their strength and stiffness, and improve their tensile strength and torsional resistance.
