Create A Whole Industrial Chain Of Space Metal

Aerospace Haiying (Harbin) Titanium Industry Co., Ltd. (referred to as Haiying Ha Titanium) is a high-tech enterprise that researches and produces high-end titanium products for aviation, aerospace, shipbuilding and other industries. According to Xiao Bo, secretary of the Haiying Harbin Titanium Party Committee, the company has invested a total of 1.675 billion yuan in the construction of a special titanium industrial park in the Harbin Aerospace High-tech Innovation Industrial Park. And when put into use, it can reach an annual production capacity of 300 tons of titanium alloy castings, 200 tons of titanium alloy forgings and complex sheet metal parts."

"This is the wing surface of the aircraft. When the aircraft flies at supersonic speed, the temperature of its wing can reach 500°C. It must be made of a light, tough, and high-temperature-resistant material, and titanium alloy can just meet these requirements. .”

"This is the air rudder. It can adjust the flight direction of the aircraft by changing the air flow. Because it is on the surface of the spacecraft, titanium alloy is the most suitable for high temperature resistance and corrosion resistance."

In Haiying Harbin Titanium Industrial Park, facing a row of bright silver titanium alloy products with different shapes, Haiying Harbin Titanium Specialist Zhao Hong professionally explained: "This is a bellows, which is equivalent to a spring. The function of elastic connection can be realized, the flight environment of the spacecraft is complex, the stretching length is different, ordinary materials are easy to deform or even break, and titanium alloy has good strength, plasticity and fracture toughness, which is just a match."

Titanium's "power" is so powerful that it is not easy to "tame" it. According to Zhao Hong, in order to improve production capacity, Haiying Ha Titanium Titanium Industrial Park has introduced many state-of-the-art titanium alloy production and processing equipment at the beginning of its construction. "In the first phase of the project, a new titanium alloy casting plant, titanium alloy precision plastic forming plant, titanium alloy machining plant, etc. were newly built, and nearly 300 sets of process equipment were newly added." Zhao Hong said.

In the plastic forming workshop of the industrial park, hydraulic presses with a height of more than ten meters are working rumblingly, and operators in special white uniforms are processing titanium alloy plates. Zhao Hong said: "The heating temperature of the hydraulic presses can reach a high temperature of seven to eight hundred degrees. , skilled workers must wear heat-insulating clothing, heat-insulating gloves and dust masks to operate, and can heat and press titanium alloy plates into specified shapes." The entire workshop, looking around, is distributed with various large-scale vacuum diffusion welding furnaces, etc. Equipment, there are different production lines such as hot press molding. Each production line is like a small workshop that can directly process finished products.

In order to process titanium alloys into structural parts of various shapes to better meet aerospace needs, Haiying Ha Titanium also uses 3D printing technology to produce titanium alloy parts and components. Zhao Hong pointed to a finished part and said: "This is made by 3D printing technology." There are about fifty or sixty holes distributed, which is like an exquisite work of art. According to him, Aerospace Haiying's 3D titanium alloy printing technology has been in the leading ranks in China, and now it can use 3D printing methods to manufacture complex parts that cannot be realized by other traditional methods in a short time, have complex structures, and are difficult to process and assemble.

At present, Haiying Ha Titanium has five core capabilities of titanium alloy precision casting, titanium alloy precision plastic forming, titanium alloy powder preparation, electron beam additive manufacturing, precision machining and system integration. "We plan to build low-cost manufacturing of titanium alloys, high-temperature alloys, powder metallurgy molding, additive manufacturing products and services, additive equipment design and manufacturing, new material R&D and manufacturing in the second phase, and gradually build the industrial park into a center in Northeast my country. 'Titanium Valley'". Xiao Bo, Secretary of the Haiying Harbin Titanium Party Committee, is full of confidence in the future development of the company.

In the future, Haiying Harbin Titanium will continue to implement the development concept of "three highs and one new" of high starting point, high technology, high-end products and new mechanisms. Based on the existing product technology, through continuous research and development, it will extend to the upstream and downstream industries of the product. Gradually form a complete industrial chain of titanium products, transforming the enterprise from traditional titanium alloy parts manufacturing to an internationally influential enterprise that provides complete sets of equipment manufacturing and overall technical solutions. At the same time, the industrial park will gradually be built into a domestically leading and internationally advanced enterprise. It is a well-known R&D and manufacturing base for high-end titanium alloy products in the industry.
