As modern industry develops, the performance requirements for materials are becoming increasingly demanding, especially in cutting-edge fields such as aerospace and energy power. These fields require equipment that is lightweight, strong, corrosion-resistant, and stable at high temperatures. TC4 titanium alloy, with its unique physical and chemical properties, is the ideal solution to these problems. However, using titanium alloys to cast double-layer blade impellers is very challenging. Titanium alloys are susceptible to shrinkage, thermal cracking, and compositional segregation during casting, and the complex structure of double-layer blades worsens these issues. Recently, a customer commissioned NBSM to develop a batch of TC4 titanium alloy castings for double-layer blade impellers made of high-strength TC4 alloy. The impellers have a maximum rotating diameter of 427 mm, an outer wall thickness of 9 mm, and a blade thickness of 3 mm. Through several rounds of technical seminars and process tests, the NBSM technical team gradually discovered the key technology for casting titanium alloy double-layer blade impellers. They effectively reduced the impurity content in the titanium alloy by optimizing the melting process, thereby improving the purity and casting performance of the material. At the same time, they adopted an advanced pouring system and solidification control technology to ensure the smooth flow of the titanium alloy melt and precise solidification. This effectively avoided shrinkage holes, thermal cracks, compositional segregation, and other problems, ensuring the performance and stability of the internal double-layer blades of the impeller. The successful development of titanium alloy double-layer blade impeller castings is only the beginning of this scientific and innovative journey. As science and technology continue to progress

The high-end manufacturing field has put forward multi-dimensional and stringent requirements on the comprehensive performance of structural materials due to the rapid development of modern industry. In cutting-edge fields such as aerospace and medical device research and development, there is a desire to achieve high strength and light weight as well as key properties such as corrosion and creep resistance. TC4 titanium alloy (Ti-6Al-4V), a typical α+β dual-phase alloy, has excellent specific strength, thermal stability, fatigue resistance, and corrosion resistance. These properties make it a material that meets the above requirements. However, this material presents challenges in the precision manufacturing process. Due to its high strength and toughness, low thermal conductivity, and low elastic modulus, work hardening occurs easily during cutting. This leads to a sharp increase in cutting temperature, which affects forming accuracy. Pores and thermal cracks easily form during welding, and the welded area easily oxidizes at high temperatures.Recently, Nanjing Baotai was commissioned by customers to manufacture a batch of TC4 titanium alloy cable winch bases. This batch of structural parts is made of titanium alloy TC4 and has a maximum length of 1930 mm, a maximum width of 1160 mm, and a height of 800 mm. The challenges in producing this batch of titanium alloys are:1. The titanium alloy base has a complex structure, and there are strict tolerance requirements in many places. The minimum tolerance range is 0.1 mm, and there are requirements for multiple geometric tolerances, concentricity, etc. 2. Titanium easily reacts with gases such as oxygen, nitrogen, and hydrogen at high temperatures, forming brittle compounds that result in weld embrittlement and decreased plastic toughness. The high solubility of molten titanium in hydrogen and oxygen, as well as the rapid precipitation during solidification, can lead to the formation of pores. These pores create stress concentration points in titanium alloy welds, thereby reducing their quality.3. The thermal conductivity of titanium alloys is only one-quarter that of steel. Local high temperatures during welding lead to significant temperature gradients and deformation. Titanium alloys react easily with oxygen and nitrogen at high temperatures. Tooling must be designed in coordination with the gas protection system to prevent oxidation embrittlement. The elastic modulus of titanium alloys is relatively low, and the base's large welding area results in significant residual deformation after welding, easily causing the workpiece's shape and size to change.After many rounds of discussions about the process and technical tests, the Baotai technical team determined the main technical aspects of manufacturing and processing the TC4 titanium alloy cable winch base. They analyzed the three-dimensional model, optimized the machining process, designed the tooling, accurately controlled the processing speed, and strengthened the cooling measures to ensure the accuracy of the internal and external processing. Optimizing the welding process effectively controls deformation and dimensional changes after welding and significantly reduces defects generated during the welding process. The successful manufacturing of the titanium alloy cable winch base is a significant step forward in science, technology, and innovation. As science and technology continue to advance and production technology continues to improve, the application scope of titanium alloys will expand to more key areas. As new technologies are developed, the market for titanium alloys will grow, and we will be able to meet the needs of different industries for high-performance materials. Guided by market demand and customer satisfaction, we make full use of our technical equipment's advantages and constantly pursue improvement and innovation to enhance the company's technical strength and market competitiveness.

Titanium is known as a "strategic metal" due for its high specific strength, non-magnetic properties, and excellent corrosion resistance. It is widely used in cutting-edge fields such as aerospace, the ocean industry, and the military. However, the excellent properties of titanium also make its plastic processing difficult. Processing large-diameter, thin-walled, seamless titanium tubes has always been a technical challenge in the industry.Recently, however, our special materials subsidiary has successfully developed large-diameter, thin-walled, seamless titanium tubes, including φ368*5.5*6000, φ219*5*6000, φ159*4*6000, and φ140*3.5*6000. After inspection, the tubes' size tolerance and performance meet the requirements of the GJB 9579-2018 "Specification for Titanium and Titanium Alloy Seamless Tubes for Ships" and the GB/T 3624-2023 "Titanium and Titanium Alloy Seamless Tubes," reaching the leading domestic level. The successful development of this product addresses an urgent need for key domestic specialized equipment and demonstrates the company's strength in titanium seamless pipe manufacturing.To solve the technical difficulties in processing large-diameter, thin-walled, seamless titanium tubes, our company organized relevant production and technical experts and established a key research project team. Under the leadership of our founder, Mr. Deng Guishun, we achieved several key breakthroughs in large-diameter seamless titanium tube production technology through equipment improvement, technological innovation, and continuous efforts. (1) Overcoming the production technology bottleneck of large-diameter, thin-walled, seamless titanium tubes with an ultra-large diameter-to-thickness ratio (D/S ≥ 60);(2) Through bold experimentation and technological innovation, the only current method of producing large-diameter seamless titanium tubes by perforation + cold rolling tube mill has changed. A perforation + extension + drawing processing method has been creatively realized, filling the domestic gap.(3) The outer diameter, wall thickness, and length of the tubes exceed the maximum sizes specified in the GJB 9579-2018 "Specification for Titanium and Titanium Alloy Seamless Tubes for Ships," GB/T 3624-2023 "Titanium and Titanium Alloy Seamless Tubes," and other standards, expanding the titanium market's application prospects.(4) By adopting advanced tube mouth shrinking technology and improving the drawing head's structure, the drawing head's length is reduced from 250 mm to 20 mm, greatly reducing material loss.In the future, our company will continue to innovate and improve, leverage the advantages of our technical equipment, achieve technological breakthroughs, optimize the production process, reduce costs, and produce this type of large-diameter, thin-walled, seamless titanium tube at a lower cost (though slightly higher than small-diameter titanium seamless tubes). I believe that, in the near future, large-diameter, thin-walled, seamless titanium tubes will be widely used in the shipbuilding, chemical, vacuum salt production, metallurgy, and electrical industries, contributing to the development of China's high-end manufacturing sector. We welcome colleagues from all walks of life to strengthen cooperation and create brilliance together!
