Recently, the Anshan Iron and Steel Wire Plant Stock Company for 60 million tons of production line of new breakthroughs in wire size limit successful, producing the largest size Φ25mm wire products.cast bronze Angang Steel thus become the second in China after the wire with mass production specification products, the ability of the enterprise.
bronze bushing Anshan Iron and Steel Wire Plant Stock Company organized a full range of technology products to overcome the technical specifications of research to bring a large rolling slow, temperature control fluctuations, into the circle of good, dry bushing easily spinning coil resistance, tension control, impact on the ring difficult to collect large rolls and many other difficulties, by optimizing the design of control procedures, improved production tools, and other measures to adjust the control parameters of rolling solve one problem.
plain bearing The Φ25mm specifications successful development and production of wire products, not only to fill the Anshan Iron and Steel wire a major gap in the specifications to achieve full coverage wire product specifications,sleeve bushing but also further enhance the competitiveness of Anshan Iron and Steel Wire and market share brand laid a solid foundation.
DU bushing Φ25mm specifications versatile and wire products, most of the varieties of special steel, steel fasteners, such as automotive, high-grade spring steel, bearing steel, etc., the market outlook is generally optimistic about the industry.
bushing Bearing industry profits by four into a high-end products are still lagging behind.
brass bushing China's bearing industry in 2010 sales revenue and profit growth surpassed the three into, and profit growth than revenue growth.
China Industry News reporter recently learned from the China Bearing Industry Association, China's bearing industry in 2010 achieved rapid development, the end of 2010, bearing well-run industry production,Mould guide plate economic efficiency has improved exports rebounded sharply, imports still on 旺势.
The rapid development of bearing industry, but also key areas of our country independent of the major technologies and equipment have made outstanding contributions. However, the Secretary-General Wang Quanqing China Bearing Industry Association,plastic bushing told this reporter admitted that the pace of development in China is still bearing the high-end host can not keep up the pace of development.
This reporter learned that, in the high-speed railway in China wind power bearing spindle bearings, bearing accelerator is still a wide gap between the fields. Among them, the speed of more than 160 km EMU used in bearings, SKF from Sweden is still full at the imports and other international giants.
It is worth mentioning that China Bearing Industry Association, organized in 2010, a large aircraft, high-iron bearings and bearing joint research, and has achieved initial results. Bearing industry optimistic to expect that research in accordance with the current development speed, and if all goes well, the next two or three years, Chinese-made high-speed railway will be able to truly support bearings.
Revenue mark.
Although the final statistics have not yet released, but preliminary data show that the bearing industry in 2010 will be 突破千亿元 main business revenue mark, reaching 120 billion yuan, the growth rate will reach 30%. In the automotive, agricultural machinery, household appliances industry driven, increased demand for small bearings in 2010, predicted that the annual bearing production will reach 150 million units, an increase of 36.36%. Expected total profit of 6.5 billion, an increase of 38.3%.
Bearing in 2010 will reach 4.15 billion units exported, up to reach 53.65 percent, compared with 28.9% growth in 2008; export volume will reach 3.32 billion U.S. dollars, an increase of about 63.6%, compared with 11.4% growth in 2008.
Wang Quanqing analysis, export growth was mainly due to the development of China's bearing industry over recent years, products bearing the micro level of technical quality is close to international standard, miniature bearings in the world market, has occupied a stable market.
Bearing imports in 2010 will reach 18 million units, up 30%, compared with 13.7% growth in 2008. Use of foreign exchange of imports will reach 3.8 billion, an increase of 34.38%, compared with 41.8% growth in 2008 or so. Import deficit may reach $ 480,000,000.
New R & D progress.
2010, the advantages of the national bearing industry research and development in three key areas of ten major technologies and equipment 106 supporting bearing 528 kinds, the annual sales income of 9.2 billion, the product reaches the level of similar foreign products.
Wang Quanqing stressed that the bearing industry in 2010, key areas of our country independent of the major technologies and equipment to make a contribution.
Among them, the "Shenzhou V", "Shenzhou VI", "seven gods", "Chang'e I", "Chang'e II" and the high-thrust rocket, "Jian Shi," as the representative of the aerospace, aviation and defense equipment, bearings supporting all based on the domestic, with completely independent intellectual property rights.
And miniature ball bearing design and manufacturing technology and material quality to meet international advanced level, with strong international competitiveness. Miniature ball bearings grinding, super finishing and assembly of automated production lines, the whole industry has increased to more than 3,000.
This reporter learned that, in the above mentioned 106 species of major technical equipment supporting bearings, including the international advanced level of the wind turbine yaw, variable pulp bearings, nuclear power plant secondary pump bearings, bearing quasi-high speed passenger trains, heavy rail speed truck bearing, high-power locomotive bearings, cement mill stand bearings, bearing a new generation of CT machines, the third generation wheel bearings units, long-life automotive water pump bearing, super precision bearings rolling mills, continuous casting production line bearing Segment and have achieved industrialization.
In addition, hydraulic crawler cranes kiloton bearings, high-powered agricultural equipment, bearings, high-speed steam flow spinning bearings, do tons of coal underground mining equipment bearings, major CNC machine tool spindle, rotary table bearings, 12,000 m high reliability ultra-deep drilling rig bearings, high speed, high temperature, long life bearing chemical equipment, long-life bearings and thin-walled mine robot shaker bearings have also been successfully developed and industrialized.
"Internal injuries" troubled industry.
However, bearing problems in development of the industry can not be ignored.
As China's emerging strategic industries (such as high-speed railway, large aircraft) and high-end equipment manufacturing (such as some high-speed precision machine tools) the development of high-end bearings imports growing rapidly. Currently all imports of high-speed rail bearings, part of the high-speed precision machine tool bearings need to be imported. In the long run, on the growth of China's emerging strategic industries will be adversely affected.
Not keep pace with the development of high-end part of the host bearing the pace of development. First, instability due to raw material properties, resulting in bearing life and reliability of the instability, it is difficult to enter the host market; second is due to the rapid development of high-end equipment, all kinds of high-end bench test equipment, bearings and other modern inputs too large experimental methods not kept pace, resulting in bearing R & D progress has been slower. Basic components as a high-speed train rail bearing areas, the Swedish SKF, German FAG, NTN Japan and other international giants still firmly occupy the Chinese market.
In addition, SMEs, due to the weak scientific basis, capital is weak, the majority of the lower level of automation, slow the pace of adjustment of product structure, resulting in value-added products is generally low, affecting the pace of development of SMEs.
