| Abstract: | A process for hot-dip galvanizing of low-carbon steel wires with small diameters used for manufacturing of armored cables by vertical payoff method was introduced,which is modified from the process based on leaning payoff method.The process flow is composed of:(1) payoff;(2) annealing;(3) lead bath quenching;(4) water cooling;(5) pickling with hydrochloric acid;(6) water rinsing;(7) fluxing;(8) drying;(9) hot-dip galvanizing;(10) wiping with charcoal powder;(11) air cooling;(12) water cooling;and(13) take-up.The process parameters of hot-dip galvanizing as well as the methods of vertical payoff and wiping with charcoal powder were described in detail.The effect of improper pretreatment on coating quality was pointed out.The formulations of pickling bath and fluxing agent were given.Some measures for preventing and eliminating surface defects of coatings were presented based on analysis of their causes.The low-carbon steel wires produced by the process for armored cables meet the requirements of BS EN 10257-1:1998 standard. |
