In order to adapt to the continuous development of high-speed rail construction, the annual investment in railway construction has continued to increase. The total scale of China's railway fixed asset investment plan in 2010 is 823.5 billion yuan, of which: the capital construction investment plan is 700 billion yuan, the renovation investment plan is 21.4 billion yuan, and the railway locomotive and rolling stock purchase investment scale is 100 billion yuan. In 2011, the total scale of China's railway fixed asset investment plan was 850 billion yuan, of which 700 billion yuan was capital construction investment, and the investment plan for renovation and transformation was 24 billion yuan; the investment scale of railway locomotives and rolling stock purchases was 126 billion yuan.
In my country’s high-speed railway construction projects, infrastructure and locomotive manufacturing account for a relatively large proportion of the overall investment, and the procurement of raw materials and spare parts takes up a large part of its cost. Therefore, traditional track infrastructure materials and locomotive manufacturing The market space for spare parts is huge. Among them, many companies are involved in steel rails, railway elastic components, railway fasteners, waterproof materials, axles and wheels. Of course, in the construction of high-speed railways, construction projects such as stations, tunnels, and bridges consume more construction steel such as rebar and wire rods, which basically account for 60% of the overall steel consumption.
