堆焊耐磨板加工中四道火的工序

  堆焊耐磨板上海11选5开奖结果在进行加工时需要经过退火、正火、淬火以及回火这四道火的工序,现简单介绍如下。

        1、TUIHUO

        将钢管加热到一定温度并保温一段时间,然后使它慢慢冷却,称为退火。堆焊复合耐磨管的退火是将钢管加热到发生相变或部分相变的温度,经过保温后缓慢冷却的热处理方法。退火的目的,是为了消除组织缺陷,改善组织使成分均匀化以及细化晶粒,提高钢管的力学性能,减少残余应力;同时可降低硬度,提高塑性和韧性,改善切削加工性能。所以退火既为了消除和改善前道工序遗留的组织缺陷和内应力,又为后续工序作好准备,故退火是属于半成品热处理,又称预先热处理。
