Product Description

Rail to rail type is the number of quality kg long per meter representation. China railway rail used on the 75kg/m, 60kg/m, 50kg/m, 43kg/m and 38kg/m etc. several.

With I-shaped section optimal flexural performance by adopting the section shape of the rail, a rail head,

The rail and rail base is composed of three parts. To make the rail better endure all kinds of force, ensure the necessary strength condition, the rail shall be of sufficient height, its head and bottom should be of sufficient size and height, waist and bottom should not be too thin.

These types of rail, the rail has stopped production of 38kg/m, 60kg/m, 50kg/m rail on the main line and special line laying, generally laying rail 43kg/m. For heavy haul railway and the railway section is particularly busy, laying rail 75kg/m.

In addition, in order to suit the needs of turnout, bridge and seamless line structure, the railway of our country also adopts a special section (font and axis asymmetric rail industry). We used more as a dwarf special section rails, referred to as AT rail.

The standard length of rail in China for the 12.5m and 25.0m two. Severe, heavy rail using standard length rail 25.0m, other types of rail can adopt 12.5m25.0m standard length rail.

"Interim Provisions" 250km/h technical conditions of passenger dedicated rail 60kg/m, 250km/h passenger dedicated line (both rail freight) standard rail scale length of 100m.

Three kinds of curve shortening track length than the standard 12.5m 40, 120mm 80, short track, there are three kinds of 25.0m than the standard rail short 40, 80, 160mm.

China's rail per meter of roughly the number of kilograms of weight, can be divided into crane rail (rail crane), heavy rail and light rail three:

The crane rail is divided into QU120, QU100, QU80, QU70 four, material is usually steel, single biggest is QU120 up to 118kg/m.

The heavy rail. According to the steel grades are divided into: ordinary containing manganese steel rail, a copper containing carbon steel rail, high silicon steel containing copper, copper, manganese steel rail track rail, rail and other silicon. There are mainly 38, 43, 50kg three. In addition to 45kg rail for a few on the line, 60kg in the large capacity and high speed rail lines have been planned with. GB2585 81 specifies 38 ~ 50kg/m in China rail technology condition, the size and the code as shown in Table 6 - 7 - 10 below.

In 2007, China promulgated a new standard GB 2585-2007, except for 38 ~ 50kg/m, the new added 60kg/m and 75kg/m two types of heavy rail.
