Since July 2014, between the South Chang Zi and Pingshun Station of the newly-built railway channel in middle south of Shanxi, the railway department successfully opened up the comprehensive test of heavy-load railway of 30T spindle, marking the new breakthrough in our heavy-load railway technology. Analyst points that with the improvement of railway bearing housing technology, the high-speed rail basically realized domestic manufacturing, and the related patents have been gradually accepted. As the core part of high-speed rail, railway bearing industry will greet new opportunities.
Technology breakthrough in heavy-load railway industry
Heavy-load transportation is the internationally recognized development direction in railway freight, while the axle load represents its development level. Currently, rail wagon in our country commonly uses 23T axle load. In recent years, in order to speed up to develop heavy-load transportation, railway department, through independent innovation, has successfully developed 25T axle load heavy railway complete technology that has been successfully applied in Daqin Railway (8.16,-0.530,-6.10%) etc. Combining the technology of the railway channel project in Shanxi middle south, the railway department opened up the comprehensive R&D of 30T axle heavy-load technology, systematically organized the tackling of core equipment and key technology, initially developed the 30T axle engine, 30T axle wagon and electronic control air brake system, and the same-phase power supply technology and energy-saving traction transformer; initially developed and applied the 30T axle heavy-load carrier roller track structure, heavy steel rail, turnout and related complete technology, making the new breakthrough of heavy-load railway technology in our country.
This test involved 6 systems, 20 professional directions and 77 test projects in rail vehicle, permanent way engineering, communication signals, traction power supply, heavy-load transportation, and vibration noise, systematically verifying the safety, compatibility and suitability of fixed facilities and mobile equipment of 30T heavy-load railway when in operation. Up to now, it has tested 100,000 miles, and will lay a solid foundation to open up the operation of 30T axle heavy-load railway in China, further improve the innovation level of the related technology, and form the complete technology system with proprietary intellectual property rights.
Railway bearing industry faces opportunities
This year, high levels keep the promotion of the high-speed rail in overseas market, and breakthroughs were made not only in the traditional region of Southeast Asia and South Asia, but in the USA and Russia, in addition, the combination of China Southern and Northern Locomotive is also performed to clear the obstacles away for high-speed rail expansion and development. So far, it costs less in China’s high-speed railway construction, and according to the analysis by the World Band, the cost in Europe is 150-240 million yuan/km, 470 million yuan/km in California, and the world average cost is 200 million yuan/km, however, according to the research of China Academy of Railway Sciences, the average cost in China is 129 million yuan/km, less than 2/3 in the world.
In order to introduce foreign carrier roller manufacturers , we have established joint ventures with overseas rail equipment enterprises including Kawasaki-Sifang Co., Ltd. (24.50,-2.550,-9.43%), Bombardier Inc-BSP, ALSTOM-CNR CRC, Siemens-CNR TRC, and developed a series of products. On the key technology of high-speed trains, so far CNR and CSR has basically realized overall nationalization with the rate of about 90%, additionally, the patents of Chinese high speed railway has been gradually accepted in abroad. Insiders hold that railway bearing industry, as the core part of high-speed railway, is developing fast. Together with the improvement of railway technology, it will meet new opportunities in bearing field.
