Qinghai: Promote the high-quality development of Qinghai's titanium-magnesium light alloy industry chain

Titanium and magnesium have excellent properties and are widely used. Titanium is known as "future metal" because of its good corrosion resistance, excellent mechanical properties at high and low temperature, high specific strength and good biocompatibility. Titanium alloy, as a new material with high performance, has been widely used in national defense weapons, aerospace, energy and chemical industry, marine engineering, rail transit and other fields. Magnesium is one of the most abundant elements in the earth's crust, which has the advantages of high specific strength, high specific stiffness, machinability, low processing cost and easy recovery. Magnesium is widely used in energy, rail transit, automobile, construction, 3C and other important industries. It is a unique strategic metal and new structural material in China.

According to the report on the development of China's titanium industry, the supply of titanium has increased rapidly in the past five years. In 2022, China produced about 180000 tons of titanium, of which 46% were used in aerospace, energy, chemical and other key areas of component production. In the future, with the higher requirements for localization and lightweight equipment in aerospace and other fields, the demand for titanium and titanium alloy parts will also increase greatly. China's original magnesium output in 2022 is 893600 tons, 80% of which is used in automobile manufacturing and aerospace parts manufacturing. With the demand for high-end aerospace equipment and lightweight automotive parts, the demand for magnesium alloy applications will continue to grow.

Qinghai Province is rich in titanium and magnesium resources. Take the 2000 ton / day mining project on the south slope of Tingcha Mountain in Wulan County, Haixi Mongolian Tibetan Autonomous Prefecture as an example, the mining area is 1.21km2, the mining scale is 2000 tons / day, and the service life of the mine is 42.7years. At present, the metal magnesium integration project of Chaerhan Salt Lake has lower carbon dioxide emissions than the current modified Pijiang method in China, and the metal magnesium produced is the cleanest magnesium in the world. Qinghai Salt Lake magnesium Industry Co., Ltd. now has a metal magnesium production line of 100000 tons / year, and Qinghai Haijiangte magnesium Industry Co., Ltd. has built a magnesium alloy production line of 56000 tons / year. At present, the metal magnesium in Haixi state has not been produced stably and continuously, the preparation cost is high, and the size of the prepared magnesium ingot is small, so it can not be applied on a large scale.

To create the industrial "four places" is the direction that General Secretary pointed out for the high-quality development of Qinghai, and it is the action path to build a green and low-carbon circular development economic system. We should base ourselves on the advantages of resources and keep pace with the times to promote the transformation and development of the titanium-magnesium light alloy industry in Qinghai, and contribute to writing a chapter of Chinese-style modernization in Qinghai.

one。 Jointly build a "industry-university-research" platform with complementary advantages and mutually beneficial win-win situation

Relying on the existing technology research center of Qinghai Province, we actively cooperate with Chinese universities, scientific research institutes and large enterprises to build a cooperation platform for "production, learning, research and application" of titanium and magnesium light alloys. On the one hand, by means of introducing and hiring, introducing high-end talents and expert consultants from key units of the industry, relying on the advantages of the platform and specific projects as the carrier, continue to attract high-end talents and constantly solve the technical difficulties existing in the whole industry chain of titanium and magnesium light alloys. On the other hand, relying on the advantages of talents, scientific research, projects, equipment, information and other resources of the platform, and combining the favorable conditions of industry, policy, environment, capital, and humanities, we will continue to make breakthroughs in technology research and development, technology transfer, technology services and personnel training, so as to achieve a mutually beneficial and win-win industrial pattern with complementary advantages.

two。 Create a platform for industrial sharing, technology sharing and collaborative development

Relying on the rich titanium and magnesium resources and green energy in Qinghai Province, we have opened up the resources of titanium and magnesium light alloy product development, design, manufacturing and technical information to the society, release the demand for R & D design, inspection, quality control, industrial chain construction, key technological breakthroughs, and the introduction of key talents, so as to continuously tap and enhance the R & D potential of the core equipment of the industrial chain. Promote the common development of the industry by sharing advanced equipment in the province, and at the same time jointly undertake major national scientific and technological projects with key enterprises in the industry to jointly tackle the problem of "sticking neck" of key projects in national basic fields, to achieve efficient utilization and value sharing of technological resources.

three。 Create a diversified service system, improve the layout, symbiosis and co-prosperity

Relying on the existing technology and professional conditions in Qinghai Province, we will create a diversified service system for the high-end equipment manufacturing industry, especially the titanium-magnesium light alloy new material industry, and promote the transformation, upgrading and rapid development of the new materials and equipment manufacturing industry in Qinghai Province. Strengthen the cultivation of "specialized and special new" enterprises, so that these enterprises can continue to make efforts in the aspects of "specialization, refinement, characteristics and novelty", adhere to the weak points of focused titanium and magnesium light alloy industry chain, and create a number of strong specialized and special new manufacturing enterprises. improve and serve the layout of the industrial chain.

Fourth, the construction of information platform, digital empowerment, innovation-driven

High-end equipment manufacturing industry, especially related to the construction of titanium and magnesium new materials industry chain, should adhere to the development idea of digital reform to enhance the level of industrial modernization. On the one hand, strengthen the support of science and technology to create a new engine driven by innovation; on the other hand, explore digital empowerment and build a new system of modern industry. In the aspect of technical design, we should vigorously develop the technology center based on auxiliary design and system simulation, and integrate the concept of lean production to optimize the design, so as to achieve the effect of optimization of production process, rationalization of structure layout, energy saving and consumption reduction in production process. In the aspect of digital empowerment in the construction of industrial chain, explore the information management platform of industrial chain process, realize the interconnection of information in the whole industrial chain process, and provide the technical basis of borderless information flow for improving efficiency, reducing cost and continuous innovation. In the aspect of digitalization of enterprise management, we should build Internet special line and internal local area network, and apply related information systems such as office automation system, production management information system, human resources information system, etc., which complement each other with the information management platform of the industrial chain process, eliminate the isolated island of information, and establish a new system of cooperative work and collaborative development.

Fifth, lay out the whole industry chain economy, cooperate across regions and create value together.

From the component manufacturing link to the raw material production and product precision processing, the whole industry chain is gradually formed. The first is to improve the upstream industrial chain, extending forward from the manufacturing link, to build new mining and mineral processing plants, and the second is to improve the downstream industrial chain, extending backward from the manufacturing link, strengthening inspection, recycling of waste products, precision processing and other links to improve the added value of products.

In terms of titanium alloy industry chain: take the 2000 t / day mining project of titanium ore on the south slope of Dingcha Mountain in Wulan County, Haixi Prefecture as an example. According to the mine reserves and taste, a production plant with an annual production capacity of 30,000 tons of sponge titanium can be built in Wulan County Industrial Park. The cost of sponge titanium can be reduced by 30% and 40% by electrolytic process, and then the sponge titanium can be transported to the relevant smelting enterprises in the province to complete titanium ingot smelting. Then transport the titanium ingots to the enterprises specializing in titanium alloy parts and equipment manufacturing in the province for parts production. To realize titanium alloy mining from titanium ore in Qinghai province, → mineral processing → electrolysis to prepare sponge titanium to prepare → titanium ingots smelting → titanium alloy parts extrusion / forging → titanium alloy parts precision machining industry chain.

In terms of magnesium alloy industry chain: the price of magnesium ingots can be reduced by upgrading or building a new electrolytic magnesium ingot production line in Haixi Prefecture, relying on the advantages of talents, scientific research, projects, equipment, information and other resources of the "industry-university-research" platform to improve the production process of magnesium alloy plates, produce magnesium alloy slabs through specific processes, and match the corresponding magnesium alloy precision processing enterprises. To achieve magnesium alloy materials from magnesium ingots to produce → magnesium alloy slab extrusion → magnesium alloy parts precision machining of the complete industry chain.

To promote the high-quality development of the titanium-magnesium light alloy industry chain, it is necessary to further share the production platform, strengthen the whole life cycle management, optimize the supply chain management, expand the service derivative manufacturing, and establish the popular science base, etc., so as to speed up the innovation of the business model, release the potential of integrated development, and realize the transformation from the traditional product-centered development mode to the integrated manufacturing mode oriented by customer demand and product service system. Create a new pattern of equipment manufacturing industry with diverse data samples, intelligent production level, perfect product system, accurate industrial customization, flexible response production and industry resource sharing, and build Qinghai into a new highland of titanium-magnesium light alloy industry in China.
