Similarly, a breakthrough has been made in the localization of major third-generation nuclear power equipment. Since the end of last year, China’s first self-developed nuclear reactor pressure vessel was delivered to Liaoning Hongyanhe Nuclear Power Station by a single system, and several million-kilowatt nuclear reactor pressure vessels and other products have been continuously delivered to users, marking the country’s millions of kilowatt-class nuclear islands. The manufacture of the main equipment is fully domesticated.
The achievements of one-and-two independent innovation are only a microcosm of the rapid growth of China's equipment manufacturing industry in the “Eleventh Five-Year Plan†period. Since the beginning of this year, major scientific and technological major projects undertaken by a group of equipment companies, such as “large-scale rapid and efficient CNC automatic stamping production lines†and “key manufacturing technology for large-scale kilowatt-scale nuclear power equipment castings and forgings†have passed the national appraisal. The world’s largest tonnage crawler crane and domestic A large number of major equipment, such as the largest stacker and reclaimer, have come out one after another. The pace of our country’s march toward a “powerful country with strong equipment†has become increasingly steady.
Industry "equipmentization" features the obvious industry scale to top the world
On July 16th, in the sound of cheerful firecrackers, the Jinan No. 2 Machine Tool Heat Treatment Center officially laid the foundation. This is another major technical transformation project that will increase the company's production capacity after “Jiji†followed by Casting Co., Ltd., D6 workshop eastward expansion and reconstruction and reinforcement of the foundry company.
Behind the continued expansion of “Ziji†production capacity is the significant increase in the market share of its domestic leading large-scale rapid-automatic stamping production line for its competitive products. "Ziji" Chairman Zhang Zhigang told reporters that since 2009, "Jiji" has undertaken more than 20 large-scale rapid automatic stamping production line orders, making the proportion of high-end products such as automatic stamping lines increase from 15% to 55%. . At present, not only the six domestic CNC large multistation press production lines used in the domestic market are all from “Zijiâ€, but also “Jiji†has become an important competitive force in the international market.
During the "11th Five-Year Plan" period, the characteristics of China's industrial structure 'equipmentization' became increasingly apparent, and the industry presented a new trend of rapid development of advanced manufacturing industries." Zhu Hongren, chief engineer of the Ministry of Industry and Information Technology, pointed out that since the "Eleventh Five-Year Plan", the "State Council has been accelerating Under the guidance of the Several Opinions on Rejuvenating the Equipment Manufacturing Industry and the State Council's Adjustment and Revitalization Plan for the Equipment Manufacturing Industry, the development of the equipment manufacturing industry in China has accelerated noticeably, and the proportion of the equipment industry to the total industrial output value has risen from 22.4% at the end of the “Tenth Five-Year Plan†period. Up to 26.15% in 2009, the level of major technological equipment autonomy has been significantly improved, international competitiveness has been further enhanced, and the technological level and market share of some products have leapt to the top of the world.
The person in charge of the Ministry of Industry and Information Technology of the Ministry of Industry and Information Technology told reporters that during the "11th Five-Year Plan" period, one of the biggest changes in China's equipment manufacturing industry was the rapid growth of scale. Statistics show that in 2010 the added value of the equipment industry accounted for more than 9% of the national GDP; the total industrial output value increased from 4 trillion yuan in 2005 to more than 14 trillion yuan in 2010; and the proportion of the total industrial output value in the country increased from 16.6%. To 20.3%; enterprises above designated size have reached more than 100,000, an increase of nearly 50,000 from the end of the “Tenth Five-Year Planâ€; employees reached 17.52 million; total assets have reached 10.4 trillion yuan, compared to the “Tenth Five-Year Plan†Some time. Among them, one landmark change is that in 2009, China's machinery and equipment industry achieved sales of 1.5 trillion US dollars, more than Japan’s 1.2 trillion US dollars and the United States’ one trillion US dollars, ranking first in the world and becoming the world’s equipment manufacturer. A big country.
Equipment support capabilities significantly enhance the achievements of major equipment localization
On June 29, the world’s largest and most advanced 18,500-ton free-forging hydraulic press was officially put into operation at CITIC Heavy Industries, marking that the forging capacity of China’s large-scale free-forged parts has reached the world level.
The successful development of the 18,500-ton free-forging hydraulic press is only one of the many achievements made by China's equipment industry in the localization of large-scale casting and forging parts in recent years. Thanks to the rapid development of China's hydropower and nuclear power business, since the "Eleventh Five-Year Plan", China's major technological equipment autonomy has made remarkable achievements, and the level of mechanical products has made considerable progress. High-efficiency clean power generation equipment (ultra-supercritical thermal power, high-power hydropower, nuclear power, and wind power) has been able to basically meet domestic demand, and the technological level and product output have entered the world's forefront. The rotors of ultra-supercritical thermal power units achieve mass production, and three million kilowatts of three generations Nuclear power key forging technology breakthroughs. The comprehensive autonomy rate of 1000KV UHV AC transmission and transformation equipment and ±800KV DC transmission complete equipment reaches over 90% and 60%, respectively. China has also become the first country in the world to invest in UHV power transmission and transformation equipment.
In recent years, the rapid development of steel, mining, cement, petrochemical, and other industries has also promoted the improvement of independent innovation capabilities of related equipment manufacturing. At present, the 10 million-ton-class iron and steel enterprises in the conventional process complete sets of equipment, 20 million tons of open-pit mine complete sets of equipment, daily production of 4,000-10,000 tons of clinker dry process cement complete sets of equipment can provide. The 300,000-ton/year ammonia synthesis equipment was autonomized, and the key “three machines†such as the one-million-ton ethylene plant cracking gas compressor, propylene compressor and ethylene compressor were also successfully developed.
For a long time, CNC machine tools are the short boards of China's equipment manufacturing industry. High-end CNC systems and heavy-duty, precision machine tools have been monopolized by foreign manufacturers. After the “Eleventh Five-Year Plan†period, the domestic high-end CNC machine tools represented by Huazhong CNC “Huazhong 8†high-end numerical control system achieved a gratifying breakthrough. The self-sufficient rate of the numerical control system and functional components for the CNC machine tools reached 60 %, The self-developed numerical control system has an average failure-free time of 20,000 hours.
In addition, large-scale aircraft science and technology major projects are progressing well. The new ARJ-21 aircraft with independent intellectual property rights is undergoing a test flight and is expected to begin batch delivery this year. The "Chongqing Engineering" and "Manned Spaceflight" have made major achievements. During the “Eleventh Five-Year Plan†period, the domestic market share of mechanical products was further increased from 80% in 2005 to over 85% in 2010, and the ability to guarantee the protection of various industries in the national economy was significantly enhanced.
