Development and application of titanium hot extrusion forming technology

Titanium and titanium alloys are widely used due to their excellent properties. Hot extrusion method is mainly affected by extrusion temperature, extrusion speed, extrusion ratio (degree of deformation) and lubricant. Computer experimental simulations combined with actual data can be used to establish appropriate extrusion processes to achieve maximum output and maximize economic benefits.
Titanium hot extrusion forming technology is an important metal processing method and is widely used in aviation, aerospace, medical and chemical industries. This technology heats titanium material to a certain temperature and then extrudes it through a die to obtain the desired shape and properties. This article mainly introduces the development and application status of titanium hot extrusion forming technology, mainly involving the preparation of extrusion billet, Heating of extrusion billet, etc.

What is the hot extrusion process: The hot extrusion process is an advanced plastic processing method that uses the high pressure transmitted by the extrusion rod on the extrusion machine to extrude the returned material enclosed in the extrusion cylinder into products with the same shape as the mold. . It has the advantages of improving the deformation ability of metals, high overall product quality, and wide product range [. Titanium and titanium alloys are difficult to deform metals and are expensive. Therefore, the hot extrusion process is suitable for the production of large-sized, thick-walled or high-demand titanium. Tubes, titanium rods, and titanium profiles are the most promising production methods.

1. Raw material preparation: Select appropriate titanium material and perform surface treatment.
2. Heating: Heating the titanium material to the hot extrusion forming temperature.
3. Extrusion: Put the heated titanium material into the mold and perform extrusion forming.
4. Cooling: Cool the extruded titanium material.
5. Post-processing: Surface treatment and size adjustment of the formed titanium material.

Extrusion billet is one of the key links in titanium hot extrusion forming technology. The traditional extrusion billet preparation method mainly includes steps such as smelting, casting, forging and heat treatment. With the development of technology, some new preparation methods have gradually been applied in practice, such as powder metallurgy and fused spray deposition. These new methods can significantly improve the density and mechanical properties of materials while reducing energy consumption and costs during the preparation process.

During the hot extrusion of titanium materials, the heating method of the extruded billet has an important impact on the quality and performance of the final product. Currently, commonly used heating methods include furnace heating, induction heating and laser heating. Furnace heating is a traditional heating method, which has the advantages of uniform heating and easy temperature control, but the heating speed is slow and the efficiency is low. Induction heating has the advantages of fast heating speed and high efficiency, but it requires the use of expensive equipment and the heating uniformity is relatively poor. Laser heating has the advantages of fast heating speed, high efficiency, and uniform heating, but it requires the use of high-precision control equipment and expensive lasers.

Titanium hot extrusion forming technology is widely used in the aerospace field, such as aircraft engine blades, fuel pipes, etc. In addition, this technology has also been widely used in the medical and chemical fields, such as medical equipment, chemical equipment, etc. With the development of technology and the expansion of application scope, the efficiency and product quality of titanium hot extrusion forming technology have been significantly improved. At the same time, with the increasing awareness of environmental protection and restrictions on energy consumption, this technology will gradually develop in the direction of greening and energy saving.

Titanium hot extrusion forming technology is an important metal processing method and is widely used in aviation, aerospace, medical and chemical industries. The development of this technology has gone through many stages and is now widely used. With the continuous advancement of technology and the expansion of application scope, the future development of this technology will pay more attention to issues such as improving efficiency, reducing costs, reducing energy consumption and environmental protection. At the same time, as new materials continue to emerge and application demands continue to increase, titanium hot extrusion technology will continue to develop and improve to adapt to new application demands and market changes.
