Abstract

Настоящим изобретением предлагается способ, с помощью которого образующий металлический туман металл, растворенный в одной части "смеси солевых расплавов, состоящей из одного или более солевых расплавов, содержащих образующий металлический туман металл" (в общем случае - солевого расплава), может быть удален и переведен в другую часть этого солевого расплава, чтобы повысить там его концентрацию. Как следствие, данный способ может применяться как одно из средств обработки солевых расплавов в различных отраслях промышленности, где работают с солевыми расплавами, содержащими образующий металлический туман металл, такой как Са или Na. В частности, при применении этого способа в производстве Ti путем восстановления кальцием (Са), этот Са, растворенный в подаваемом в электролизер солевом расплаве, может быть быстро удален (извлечен), в результате чего может быть повышена эффективность образования Са во время электролиза солевого расплава. Следовательно, можно эффективным образом проводить образование Са и восстановление TiClпри электролизе солевого расплава, и возможна стабильная эксплуатация в коммерческих масштабах. Таким образом, этот способ может эффективным образом применяться при производстве Ti или Ti-го сплава путем восстановления кальцием (Са).The present invention provides a method by which a metal mist-forming metal dissolved in one portion of a "molten salt mixture consisting of one or more molten salts containing a metal mist-forming metal" (generally a molten salt) can be removed and transferred to another part of this molten salt in order to increase its concentration there. As a consequence, this method can be used as one of the means for the treatment of molten salt in various industries, where they work with molten salt containing a metal haze-forming metal such as Ca or Na. In particular, when this method is applied in the production of Ti by reduction with calcium (Ca), this Ca dissolved in the molten salt supplied to the electrolysis cell can be quickly removed (recovered), as a result of which the efficiency of Ca formation during electrolysis of the molten salt can be increased. ... Therefore, Ca formation and TiCl reduction in molten salt electrolysis can be carried out efficiently, and stable operation is possible on a commercial scale. Thus, this method can be effectively applied in the production of Ti or Ti alloy by calcium (Ca) reduction.
