FOR 1372: Production of Titanium and Titanium-Alloys with Minimised Process Steps

基于目前的技术和研究状况，克劳斯塔尔工业大学、亚琛工业大学和弗莱堡工业大学的成员成立了一个研究小组，以复杂和跨学科的方式研究钛生产过程中的步骤最小化。研究单位背后的主要动机是日益严重的能源减少和排放增加的问题，这极大地挑战了目前对个人机动性的看法，这需要全新的交通概念，显然更轻量化的设计。研究股的总体目标是为一种步骤最少的工艺建立科学基础，这种工艺可以在大规模工业规模上实施，以生产廉价的钛材料，作为现有钛技术的替代品。该项目将包括从廉价原材料的调理，金属回收和加工到材料开发的所有内容。研究单位的分目标是：(1)利用潜在的原材料储备；(2)直接从原料中回收钛和钛合金，不需要绕道二氧化钛；(3)工艺步骤数量最小化；(4)能量输入最小化；（五）采用新型耐火陶瓷；(6)以转换和连接的方式处理，作为冶金工艺步骤的反馈；(7)开发合适的合金体系；(8)高效回收废钛。除了实际的工艺开发之外，研究单位还希望通过提供基础数据来触发钛材料生产、加工和开发领域的未来研究活动。该研究项目预计将分为两个阶段，每个阶段3年。在第一阶段，实验室调查将表明该项目所依据的概念是可行的。样品将由钛金属组成，通过各种工艺路线的最小化工艺步骤生产。该前驱体材料将被加工成低级、技术级和高级材料，并根据其生产和使用性能进行表征。同时，将开发合适的合金体系。第二阶段将包括在钛生产和加工行业的合作下向中试工厂规模转移。在这一阶段，其他部门可加入研究股，并可建立更多的国际合作。

Based on the current state of technology and research, the members of the TU Clausthal, RWTH Aachen and TU Bergakademie Freiberg have set up a research group to look at the minimisation of the process steps in the production of titanium in a complex and interdisciplinary way. The main motivation behind the Research Unit is the dramatically increasing problem of diminishing sources of energy and increasing emissions, which drastically challenges the current perceptions on individual mobility and that demands entirely new traffic concepts with a clearly higher content of lightweight designs. It is the overall objective of the Research Unit to establish scientific foundations for a process with minimised steps, which can be implemented on a large industrial scale, for the production of inexpensive titanium materials as an alternative to the existing titanium technology. The project is to include everything from the conditioning of inexpensive raw materials, metal recovery and processing to the development of materials. The subgoals of the Research Unit are: (1) utilisation of potential reserves of raw materials; (2) direct recovery of titanium and titanium alloys from their raw materials without the TiCl4 detour; (3) minimisation of the number of process steps; (4) minimisation of the energy input; (5) use of new refractory ceramics for the smelters; (6) processing by means of conversion and joining as feedback for the metallurgical process steps; (7) development of suitable alloy systems; (8) efficient recycling of titanium scrap. In addition to the actual process development, the Research Unit wants to trigger future research activities in the fields of the production, processing and development of titanium materials by providing fundamental data. The research project is forecasted to include two phases of three years each. During the first phase, laboratory investigations are to show that the concepts, on which this project is based, are feasible. The proof will consist of titanium metal produced with minimised process steps from various process routes. This precursor material will be processed into low grade, technical grade, and high grade materials, which will be characterised in terms of their production and usage properties. At the same time, suitable alloy systems will be developed. The second phase will then include the transfer to the pilot plant scale with the cooperation of the titanium producing and processing industries. Other departments may join the Research Unit during this phase and additional international cooperation may be established.
