预镀镍技术在活性钢热镀锌中的应用

APPLICATIONS OF NICKEL-DEPOSIT PRETREATMENT PROCESS TO HOT DIP GALVANIZING ACTIVE STEELS

预镀镍技术是在锌浴加镍技术的基础上发展起来的一种新技术,它可以很好地解决锌浴加镍技术所不能解决的抑制含硅量大于0.25%的活性问题。通过介绍,对这两种技术作了详细的比较。

Nickel-deposit pretreatiment process is a new technology on the basis of the process of addition of nickel in Zn bath. It can solve the problem about how to control the Fe-Zn reaction when the Si content is higher than 025%. These two processes are compared detailedly in this paper.
