Titanium and titanium alloys are hard-to-deform metals and expensive, so the hot extrusion process is the most suitable for the production of large-sized, thick-walled or high-demand titanium tubes, titanium rods, and titanium profiles (hereinafter referred to as titanium extrusions). Development of future production methods.
In the 1950s, with the industrial production of titanium, hot extrusion forming technology was rapidly applied and developed in the production of titanium materials. After decades of development, Russia, the United States, the United Kingdom and other countries can not only produce titanium and titanium alloy tubes and bars, but also extrude a wide variety of titanium and titanium alloy profiles. These profiles are not only angle bars, T-shaped bars, and grooved pipes, but also various profiles, variable-section profiles, and even dimensional tolerances, and the surface quality is such that machining is not required.
Production and application of titanium materials in various countries
The experimental work of titanium alloys in Russia began in 1953, and in the 1960s, it provided a variety of thin-walled profiles, wing profiles, hollow profiles, large profiles and siding for the rapidly developing aviation technology. Since then, Russia's titanium extrusion technology has been at the world's advanced level. There are more than ten grades of titanium alloys and more than 2,000 specifications. For example, the thin-walled profiles of OT4, OT4-1, BT20, BT14, and BT15 alloys produced have a web thickness of 1.5 to 5 mm, and a web thickness tolerance of 0.5 mm.
In addition to domestic use, the extruded tubes, rods and profiles of Russia's Upper Salda Metallurgical Production Enterprise (VSMPO) are also exported in large quantities to aircraft manufacturers and suppliers in the United States and Europe. In addition to aerospace, the Pd, Ru-containing alloy Ti-6Al-4V alloy tubes produced by VSMPO are also used in oil exploration.
The production of large-diameter titanium alloy extruded pipes in the United States ranks at the world's leading level. The United States uses Ti-6Al-4V-Ru alloy pipes with a diameter of (48-610) mm × 26 mm × 2600 mm as geothermal and offshore drilling pipes. The ultra-long Ti-3Al-2.5V-Ru alloy tube with a diameter of 650 mm × (22-25) mm × 35000 mm produced by RMI Company of the United States is used for subsea oil exploration. In addition, Ti-6Al-4V ELI alloy pipes with a diameter of 600 mm × 25 mm × 15000 mm are used for the riser pipe of the drilling support platform in the Norwegian North Sea.
Internationally, the research and development of titanium tubes is relatively slow. Only Titanium Sports Technology in the United States adopts extrusion and stretching methods to produce tubes of various shapes such as square, rectangle, triangle, ellipse, pentagon, hexagon and octagon. , becoming the only company in the world that produces titanium tubes. At present, the application of titanium tube is not widely enough, and the amount is not large, but there is a large potential market in the fields of construction, sports and leisure and special engineering.
The extrusion production of titanium and titanium alloys in my country began in the late 1960s. At that time, Baotai Company and Great Wall Steel respectively introduced a 3,150-ton hot extrusion press from Germany that can extrude titanium alloys. After nearly 40 years of development, Baotai Company can extrude titanium and titanium alloys of various specifications of tubes, bars, profiles and composite materials with simple cross-sections, with dozens of grades. These products have been widely used in various sectors of the national economy such as aviation, aerospace, satellite, energy and chemical industry.
However, compared with advanced countries, my country still has a big gap, and profiles with more complex cross-sections cannot be produced. In recent years, with the sharp increase in the demand for high-quality titanium pipes in the civil fields such as chemical industry, Western Titanium Industry, Zhejiang Wuhuan and other companies have successively introduced extrusion machines mainly used for extruding titanium pipes. In October 2009, Baosteel Special Steel introduced the world's advanced 6000T extrusion press from Germany and put it into production, which provided the necessary equipment for the production of large-scale titanium tubes and profiles in China, marking a new level of titanium extrusion equipment in my country. .
