热镀锌工艺参数对钢丝性能的影响

Effect of Pot Galvanizing Parameters on Steel Wire Property

采用相同原料钢丝 ,对热镀锌的主要工艺参数 (浸锌时间、温度、速度 )进行匹配选择 ,并分别取钢丝试样进行三项性能试验并比较 ,从中筛选最佳工艺。试验结果表明 :45 0℃ 16s热浸镀和 45 4℃ 18s热浸镀 ,钢丝的抗拉强度、扭转值、弯曲值匹配最好 ,产品合格率达 90 %以上。

To adopt the steel wires with the same raw material and to chose the main matching parameters of pot galvanizing(galvanizing time,temperature,velocity),the best parameters are chosen from the three items of property matching test of wire sample.The result of test indicates that the best matching of the strength,torsion and bend of the wire is under the conditions of at 450 ℃ for 16 s and at 454 ℃ for 18 s.The eligible rate reachs more than 90%.
