本文简要回顾了钛冶炼的历史和当前钛冶炼研究的发展趋势。目前，广泛研究了利用各种进料如氧化钛的电解和金属热还原方法。然而，在实现利用氧化物进料的熔炼工艺的实际应用之前，仍有许多挑战有待解决。为了使钛成为“普通金属”，需要一种高速、节能、低成本和低环境影响的新还原工艺。概述了钛回收的现状，并讨论了回收工艺的发展。目前，在钢铁工业中，被氧和铁严重污染的低级钛废料用于生产添加剂合金（钛铁）。在不久的将来，如果对钛金属的需求急剧增加，市场上可能会出现低等级钛废料供过于求的情况。因此，开发抗污染和有效去除氧和铁的工艺对于钛的有效利用至关重要。这些技术的发展对于通过钛冶炼和回收技术的创新来扩大钛工业至关重要。
This paper presents a brief review of the history of titanium smelting and the current trends in related research and development. Presently, both electrolytic and metallothermic reduction processes utilizing various feed materials such as titanium oxide are widely studied. However, many challenges remain to be addressed before realizing the practical application of smelting processes utilizing oxide feed. To make titanium a "common metal", a new reduction process that is high speed, energy-efficient, low cost, and of low environmental impact is required. The current status of titanium recycling is likewise outlined, and the development of the recycling process is discussed. Low-grade titanium scraps heavily contaminated by oxygen and iron are currently used for producing additive alloys (ferro-titanium) in the steel industry. In the near future, if the demand for titanium metal increases dramatically, there could be an oversupply of low-grade titanium scraps in the market. Therefore, the development of anti-contamination and efficient removal processes for oxygen and iron is essential for the efficient utilization of titanium. The development of these technologies is vital for expanding the titanium industry through innovation in both titanium smelting and recycling technologies.
