摘要

本文对稀土的固氢、隋性气泡浮游法的去氢以及稀土—惰性气泡联合去氢作用进行了试验研究

研究表明:联合处理既有效地改善了稀土化学固氢的动力学条件

又兼有气泡浮游法去氢的作用。因此

具有处理的“潜伏期”短

去氢效率高的特点

为冶金工业提供了一种新的、高效率的无毒去氢方法。

Abstract

In the Paper

the function of RE to fix H

Ar bubbles to remove H

as well as the combined process to remove H with RE and Ar bubbles have been investigated. It has been shown that the combined process has characteristics of both short latent period and a high efficient of removing H. In addition it has the advantages of fixing H with chemical method and removing H with bubble method. It provides a new efficient non-toxic method of removing H for the metallurgical industry.
