  • Large roll galvanized wire is the use of low carbon steel wire processing, after drawing forming, pickling rust removal, high temperature annealing, cooling and other processes, in the use of is more widely. The temperature of large roll galvanized wire for electroplating should be controlled at 30 to 50℃. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used.

  • Cold galvanized is in the plating tank through the current unidirectional zinc gradually plated on the metal surface, the production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust. With the rapid development of market economy, all walks of life are improving the production process and quality of products, galvanized iron wire industry is of course no exception. But because of the variety of galvanized iron wire, its characteristics and production technology are not the same.

  • The cooling circulation system uses spray to cool the drawing die, and takes away a lot of heat generated by the drawing machine in high speed drawing in time to ensure the quality of the wire. Control drawing process parameters: drawing speed 10 ~ 12m/s; Winding tension 8 ~ 10N; Measuring length 30km; The mass fraction of lubricant is 3.5 ~ 4.5%; pH value of lubricant 7 ~ 8; Lubricant temperature 30 ~ 40℃.
