  • The composition of hot dip galvanizing layer is composed of hot dip galvanizing layer, which is composed of iron zinc alloy between iron matrix and surface pure zinc layer. The shape of the workpiece is formed by the iron zinc alloy layer in hot dip, so that the iron and pure zinc layer touch outstanding. When the iron workpiece is immersed in a molten zinc solution, the initial zinc and iron (body) are formed at the interface. This is a crystal made up of zinc atoms in the solid metal iron. When two metal atoms are fused together, the gravitational force between the atoms is very small.

  • Annealing is to restore the plasticity of wire, improve the tensile strength of wire, hardness, elastic limit, etc., the wire after annealing is called annealing wire. In the production process of annealing wire, it is very important to ensure the quality of the finished wire, make the wire have certain strength and suitable degree of soft and hard. The annealing temperature is between 800 ℃ and 850℃, and the length of furnace tube is lengthened appropriately for enough holding time.

  • The production process is to roll the hot metal billet into 5mm thick steel, and then put it into the wire drawing device, draw into different diameters of the line and gradually reduce the aperture of the wire drawing disk. Production process through cooling, annealing, coating and other processing technology, and then made into a variety of different specifications of galvanized wire. Galvanized wire production because of simple process, wide application, early development. Galvanized wire or steel wire is a cold working product of steel wire, and the material used is generally low carbon steel or stainless steel.

  • 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.
