Description

Technical Field

[0001] The present invention relates to the technical field of titanium alloy processing, and particularly relates to a titanium alloy recycling device. Background Art

[0002] Titanium alloy (Ti-6Al-4V / TC4) is a material with excellent properties and is widely used in aerospace, automotive manufacturing, military, and high-end manufacturing. Due to its excellent strength-to-weight ratio, strong corrosion resistance, and good high-temperature stability, it has become an important choice for aircraft structural components. However, the production process of titanium alloy is very complex and costly. The main reason is that the refining process of titanium metal requires high-temperature smelting, and the alloying process is very delicate. In addition, during the processing of titanium alloy, the energy consumption is large and the manufacturing cost is high, which poses a certain economic pressure on the wide application of titanium alloy.

Especially in the aerospace field, a large amount of titanium alloy waste is generated during the production process. The recycling and reuse of these wastes can not only reduce resource waste but also greatly reduce production costs. The recycling and utilization of titanium alloy can not only alleviate the resource shortage problem of titanium metal but also promote the goals of green manufacturing and sustainable development.
