黑铁丝由盘条经过拉拔后的冷拔丝退火而成,盘条和冷拔丝前面已经介绍过了,今天主要介绍退火工艺。

     冷拔过程中钢丝的组织与力学性能发生变化,产生加工硬化,随着冷却便形成作,增加一班钢丝的抗拉强度,硬度,弹性极限等增加而延伸率,断面收缩率等下降,由于存在加工硬化的现象,当拉巴的变形达到一定的程度后,钢丝冷却加工性能就会 明显下降,而不适宜再继续拉拔,这时就需要对钢丝进行中间热处理,已恢复及各种加工性能,这种中间热处理的过程就称为退火。


客人订货时会经常会强调要软,我们做退火处理时就是时间更长,至于市面上一些较硬的黑铁丝做绑丝时太硬绑起来费力,绑不紧,大部分都是为了节省成本退火时间段造成的。客人收到货后放在仓库还没卖出去就有生锈一般是客人仓库比较潮,黑铁丝省去了包装前的喷油过程。针对客人常遇到的一些问题,雷德隆一直在这方面努力,改进,让客人拿到更好的产品,更好的销售,减少后顾之忧。雷德隆从事生产销售黑铁丝十三年,只为把黑铁丝做得更好!因为专业,所以值得信赖!
