  • The temperature of large roll galvanized wire should be controlled at 30 to 50℃ during electroplating. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used. Continuous production does not need heating, but needs cooling. Cooling can be in the groove side row thin wall plastic pipe, through the flow of tap water cooling, can also be used as a titanium pipe temperature control device.

  • The higher the carbon content of steel wire, the worse its plasticity, the smaller the section compression and elongation of steel wire, steel wire in rolling deformation is difficult, the width of the smaller. For alloy steel wire, because the alloy element dissolved in solid solution can improve the cold working hardening rate of steel wire, its deformation resistance is large, the rolling width is small, and it is easy to crack.
