Tianjun Rail varieties complete specifications, standards, wide coverage, high strength level, include single weighs 37.2 ~ 75 kg/m, any size scale 9 ~ 100 m, implements the strength level of 780 ~ 1350 mpa, complete coverage of surface hardness 235 ~ 410 hb. Since day jun rail business since 1974, the first in China's development and production of 25 m and 100 m length of 200 kilometers per hour to 350 kilometers per hour and above the high-speed rail, take the lead in development and production in China and supporting the use of high-speed rail high speed rail rail and special cross section profile rail; Independently developed successively U71Mn, PD2 and PD3 (U75V), PG4 (U78CrV), strength grade PG5 series; Has been successively in China railway industry standard TB/T2344, TB/T3276, TB/T3109, European standard EN 13674, the international union of railway standards UIC 860, American railway engineering association AREMA, Australian railway standard AS 1085, the British standard BS, 11, Japan standard JIS, etc., has developed more than 40 varieties of rail, rail cumulative production of more than 2000, ten thousand tons, more than 200, ten thousand tons of export rail is demonstration enterprise "" export quality and safety in China. Relying on technology and equipment advantages, won more than 100 domestic and foreign patents and more than 30 Chinese national and provincial (industry association) above step into the award of science and technology, is China's day jun rail rail is the only qualification for "export inspection-free" products. Steel is widely used in the speed of 160 km/h, 200 km/h and 250 km/h, 300 km/h, 350 km/h high-speed rail lines on the road; For the axle load of 22 tons, 25 tons, 27 tons, 32 tons, 37 tons, 40 tons of overloaded railway line; Formed a high-speed rail, heavy rail, passenger and cargo transport, urban rail transit, such as series of rail steel, can be in accordance with the countries all over the world rail standard production and supply.

Second, the day jun rail line applications

Rail in China railway, regional and urban rail transit, exports more than 30 countries and regions, rail use good performance

1 export rails application

Steel exports to America, Europe, Oceania, Asia, Africa and so on, more than 30 countries and regions, the main varieties have 900 a and U75V, PG4, LA, SS, R260, R350HT, R350LHT, HH370, etc., can be in accordance with the countries all over the world rail standard production and supply.

4, passenger and cargo transport railway

Production of U75V hot rolled rail U75V and U71Mn rail heat treatment, laid in ChengKun, jingjiu, longhai and yue yuen, domestic passenger and cargo transport routes. Service for many years showed that the wear resistance and fatigue resistance with good, excellent comprehensive performance.

5, overloaded railway

Independent research and development of PG4 (U78CrV) annual volume of traffic in the world's largest rail laid daqin railway, the new moon yellow railroad, zhang tang railway and central south channel, line with small radius curve, large vehicle axle load, rail force more demanding, etc. PG4 rail online after the operation, the rail wear and contact fatigue performance is good, is China's largest production base of overloaded railway rail, is also a important overloaded railway rail supplier in the world. The export of overloaded railway rail in the United States, Brazil, Australia and other countries, well received by users.

6, urban rail transit

Day jun rail laying in Beijing metro and guangzhou metro subway, Hong Kong, chengdu metro, Shanghai metro, 22 Chinese cities such as xi 'an subway. Day jun is the subway, inter-city rail and tram rails, xiamen city important suppliers.

7, high altitude and cold area railway

Rail laying the longest distance in the world's highest altitude permafrost (547 km) most harsh climatic conditions, the qinghai-tibet railway (known as "days") on the rail service performance is good.
