Spiral pipe production capacity growth

Time:2016-04-07 10:52:20

From the current point of view, the domestic steel consumption market potential larger areas, engineering machinery, petroleum chemical industry, power plant (nuclear power, thermal power), transport machinery (including high-speed train, automobile, aviation and military industries). Ministry of industry, "new materials industry," 12th Five-Year "development plan," said the establishment of high-quality steel base. With Shanghai, Hebei, Jiangyin as the center, focusing on the construction of high-quality special steel production base in East china. Relying on Anshan, Dalian and other old industrial bases, to build high-quality special steel base in Northeast china. In Shanxi, Wuhan, Hubei, Henan, Wuyang, Tianjin and other places to build a number of professional high-quality special steel production base. High end spiral steel pipe is a widely used material. You may have heard of aluminum, titanium, magnesium alloys, and this week we want to talk about, in the high-end spiral steel pipe which is very heavy in weight, but not in the life of a special kind of steel - high quality steel. High quality special steel is a kind of special steel varieties with high performance, long life, environmental friendliness, high technical content and high added value. At the industry level, the representative of the special spiral pipe material development direction on the protection of major national construction projects, improve the equipment manufacturing level, promote the upgrading of energy-saving emission reduction and related application technology has important significance, is the embodiment of the overall level of industrial development is an important sign of the national. National policy support for high quality steel is evident. 2015 production of 8 million tons of backward technology is flawed in high quality steel is a major equipment manufacturing, construction of major projects, strategic emerging industries and Defense advanced weapons of the core and key material, is a new high performance functional material and structural material. Due to the high quality special steel in the field of aircraft and shipbuilding are applied, so the most imaginative place is involved in the production of fighter aircraft and aircraft carrier aerospace industry theme. Public information shows that the global production and consumption of special steel in China, Japan, the United States, South Korea and some EU countries, the total production and consumption of more than 70% of the global total. While the proportion of high quality special steel is a reflection of a country's iron and steel industry development level is an important indicator of the global high quality special steel ratio in 10% to 12%, the highest proportion of more than 70% in Sweden. Germany more than second, ranking the first, followed by Japan and Italy, but also more than 20% of the total of more than 30%. The proportion of China is not more than 10%, lower than the global level. Industry analysts said, the main reason for the low quality of steel is not the cause of research and research and development of the gap caused by. Enterprises, universities and R & D institutions are the main R & D centers, these R & D departments do not have a good cooperation, are independent of the existence of interests, usually lead to waste of resources, repeated research. On the other hand, the direct contact between enterprises and downstream users has not been well established, patent applications are not enough." The key technology includes high-quality special steel, metallurgy and chemical purity Gao Jie precise control of chemical composition, the solidification process of cleanliness and uniformity control technology, high-quality steel rolling (forging) technology research, after finishing the heat treatment technology, including the organization control technology and defect detection and control technology, the development and application of Technology special steel varieties, varieties, construction process and equipment, on-line testing technology of integrated production demonstration line, promote the overall progress of special steel technology. Due to the complexity of its technology and the limitations of the use of high-quality steel has been not optimistic about the situation. The disconnection between enterprises and downstream users, but also has a certain relationship with the use of high-quality steel. At present, the domestic high-quality steel is mainly used in nuclear power, petrochemical, aviation, R & D output is limited, the industry platform is not enough, is not conducive to the increase of added value." The research and development is mainly reflected in the lack of R & D enterprises, the lack of core leading enterprises. The relevant data of the Ministry of raw material industries CCID think tank Research Institute showed that 20135 ~2010 years, the number of China's high-quality special steel patent annual growth was 117, the average annual growth rate of 34%. "Enterprises should be based on its own technology-based, Institute of Scientific Research Institute, universities, reasonable allocation of manpower, financial resources and limited resources, while strengthening ties with downstream, establish a strategic alliance to achieve cooperation and development." The analyst said. Technical level, increase the added value of the product, the establishment of benchmarking enterprises, support for small and medium enterprises, to create an industry platform, focus on breaking through technical problems, to achieve technological upgrading." In 12th Five-Year, the planning of new materials, affected by the policy, in addition to the traditional nuclear power, aviation, high-quality steel has become a trend in the selection of automotive steel. Overall distribution, some enterprises have formed a certain patent layout. Baosteel, Wuhan Iron and Steel shares and Anshan Iron and steel and other enterprises in recent years, the number of patent applications in the field of high-quality special steel into the world's top 20, has formed a certain patent layout. But from the enterprise patent, patent application China sum of the number of patent applications in the top 10 enterprises of all enterprises accounted for about 23% of the amount of patent application, and foreign top 10 leading enterprises, the left and right 55% of the total patent applications can account for all the enterprises to apply for the. The overall core technology R & D capability is a bottleneck to break through. Mentioned in the planning, by 2015, will form an annual output of high-quality steel production capacity of 8 million tons, basically meet the needs of high performance spiral steel pipe of the national key project of nuclear power, high-speed rail, ship and marine engineering, automobile, electric power and other industries.
