Product Description:

Product Description of Steel Heavy Rail with High Quality for Structure Project and Building: 

Sizes: 38kg, 43kg, 45kg, 50kg, 60kg.

Production Standard: GB2585-81, DIN, AREMA, JIS, BS, UIC, etc.

Material: 50MN, U71MN, 900A, 110A, etc.

Length: 6m-25m according to the requriements of the clients     

Usages of Steel Heavy Rail with High Quality for Structure Project and Building:

Light rail is mainly used in forest region, mines, factories and construction sites laid of the place such as temporary transport line and light motorcycles with line. Be widely used for railway, subway, transportation track, express, curve way, tunnel way and so on.

Packaging & Delivery of Steel Heavy Rail with High Quality for Structure Project and Building:

1. Packing: it is nude packed in bundles by steel wire rod

2. Bundle weight: not more than 3.5MT for bulk vessel; less than 3 MT for container load

3. Marks:

Color marking: There will be color marking on both end of the bundle for the cargo delivered by bulk vessel. That makes it easily to distinguish at the destination port.

Tag mark: there will be tag mark tied up on the bundles. The information usually including supplier logo and name, product name, made in China, shipping marks and other information request by the customer.

If loading by container the marking is not needed, but we will prepare it as customer request.     

4. Transportation: the goods are delivered by truck from mill to loading port, the maximum quantity can be loaded is around 40MTs by each truck. If the order quantity cannot reach the full truck loaded, the transportation cost per ton will be little higher than full load.

5. Delivered by container or bulk vessel

6. Delivery Time: All the Hot Rolled Steel Rail will be transpoted at the port of Tianjin, China within 30 days after receiving the advance payment by T/T or the orginal L/C at sight.

Inspection of Steel Heavy Rail with High Quality for Structure Project and Building:

We will send the MTC of the factory to the clients dirrectly which contain the anlisis of the heat, chemiqul composition, phisical characteristicas, etc.

And our inspectors will arrive at the factory to meke the inspection of the size, length, weight and quantity before the transportation from the factory.

Q:U71Mn what does "U" mean in the rail?
Rail steel (rail, steel) is used for the manufacture of locomotives, cranes and other rail steel for professional use. Most of the rail steel by oxygen open hearth and oxygen converter smelting and rolling by. Rail used in the main wear and long-term repeated load, so the requirements of wear, pressure, fatigue, welding and good toughness.
Q:What is called orbital angle?
It is a major component of a railway track. Its function is to guide the wheel of the rolling stock, to bear the great pressure of the wheel and to deliver it to the sleeper.
Q:Scrap rail has what use, what enterprise demand on rail?
The use of the old rail companies generally require coal mine tunnel laying railway enterprise, and gantry crane, crane installation, also need to track than with new rail can save much cost, use effect can be said to be the same. The waste rail can only be used as heavy steel scrap into the steel enterprise.
Q:What is the working principle of a rail profilometer?
The rail profilometer is an instrument for testing and checking the profile, two-dimensional dimension and two-dimensional displacement of the rail. According to the principle of the sensor, the rail profilometer is divided into inductance, induction and piezoelectric type.
Q:The difference between small resistance and constant resistance fastener of high speed rail
The three is in the construction of track laying, try to choose the season or time period and the minimum impact on the rail expansion, thus laying up, the problem will be a small part of.The Beijing Tianjin high-speed railway is now built long seamless rail, only the seams in the station area will be two to switch between stations, rail unit as a observation unit, each unit in the rail on both sides of the shoulder is buried with observation pile, regularly to crawl to measure the rail unit, when the amount of abnormal (also crawling is the internal stress anomaly), the need for stress relief construction, stress relief through elimination of rail because stress caused by the abnormal thermal expansion and contraction.
Q:The tracks on the stones have what effect?
When the line state occurs (level. Level. Direction), line maintenance work area workers will be used to track lifting up, then ramming into the gravel at the bottom of the sleeper, the line restored to good condition.
Q:Why are the rails made of I-beam?
H section steel is a kind of economical and economical surface profile (other cold bending thin wall steel, pressed steel plate, etc.). Because of the reasonable cross-section shape, they can make steel more effective and improve the bearing capacity. Unlike ordinary I-beam, the flange of H steel is widened, and the inner and outer surfaces are usually parallel so that it is easy to connect with high strength bolts and other components. The size of the series is reasonable, the model is complete, easy to design and use.
Q:Generally, how often do rail rails change?
This depends on the line conditions, such as the Daqin Line Heavy Haul lines, because each year the volume can reach 7 tons, generally less than a year to track, on the small radius curve rail replacement cycle is shorter, for many reasons, such as serious abrasion, stripping off block etc..
Q:What is the method to check the straightness of rail?
The measurement of rail straightness is one of the important parts of length measurement technology. The commonly used methods are straight ruler method, collimation method, gravity method and straight line method.
Q:What is the difference between rail welding and field welding of railway rails?
In my impression, the thermit welding is mostly used for track erection, and then the welded rails (several hundred meters long or more kilometers long track) are welded together at the site.
