真空熔炼 [冶] vacuum melting
vacuum refining
- 本管材是经过真空熔炼而制成的。
Our tubes are produced through the process of vacuum smelting. - 因此,真空熔炼及电子束熔炼作为冶金法的重要环节有着广泛的应用。
Therefore, as important processes of metallurgical method, vacuum refining and electron beam refining have been widely applied. - 如果合金本身对氧非常敏感,则不仅在雾化时要采取措施,在熔化时最好也采用真空熔炼。
If the alloy is in itself sensitive to the oxygen, then not only in atomization time must take the measure, when melting should better also use the vacuum melting.
