Applications of Hot Rolled Light Steel Rail for Warehouse ,Minas, Structures

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.

Heavy rail is suitable for the laying of main trunk line of the curves and the orbit of the tunnel can also be used for tower crane and other crane track.

High Quality Steel Rail

Packaging & Delivery of Hot Rolled Light Steel Rail for Warehouse ,Minas, Structures

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

High Quality Steel Rail

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.

High Quality Steel Rail

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.

7. Invoicing on theoretical weight or actual weight as customer request

8. Payment terms: 30% advance payment by T/T, 70% payment against the copy of the B/L; 100% L/C at sight, etc.

Q:What kind of steel should be used for railway rails?
The railway began to switch to rail, and after decades of improvement, the materials used were converted to steel, while the quality of steel was greatly improved. Rail used in the railway must bear great pressure, so it is necessary to use very high quality steel. The requirement of rail for steel is higher than that of other applications. The same small defect may not cause any problems in the reinforcement used by the building; however, the occurrence of the railway rail at any time will lead to the derailment of the track and the derailment of the train.
Q:Seamless rail is not afraid of expansion and contraction?
Seamless rail not thousands of kilometers without gaps, but the 25 meter long rail welding up into hundreds of metres long or even thousands of meters long, and then in the shop on the embankment, or the gap between 11 mm and a section of a seamless rail, now Shanghai Nanjing line is 303 km long ultra long seamless rail, seamless rail in order to solve the thermal expansion and contraction by slot number is not enough, now solve the thermal expansion and contraction in two ways, one is the long rail itself under all temperature stress, will be locked in the long rail sleepers, which is due to temperature change and contraction, this method is suitable for a year four small temperature difference areas, for example in the south of China. In some temperature difference regions should take another approach, namely the long rail itself does not bear the temperature stress, and stress or regular bleeding stress to automatic bleeding Method, make the long rail with temperature rise and free shrinkage, at the time of laying also try to choose the optimum temperature of the rail laying, the expansion value in the minimum range, so that regardless of the temperature rising or falling, the rail expansion always control at a minimum.
Q:What kind of welding rod should be used for rail and Q235A welding?
MG600 welding rod can be used for rail and Q235A welding.
Q:What is the material for railway track
The main grades of domestic rails are U74, U71Mn, PD2, PD3 and BNbRE, of which PD2 is general carbon steel, SQ process, fully quenched rail, PD3 is high carbon micro vanadium low alloy rail, BNbRE is low alloy rail with niobium rare earth treatment.
Q:Why is there a gap between each rail on the railway?
Rail is the main component of 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:Why are the rails made of I-beam?
The rails are made of type H steel, one of i-beam.
Q:What's the difference between a high-speed rail and an ordinary one?
Not only does the train speed run faster than the train, but the infrastructure (track, signal, communication and catenary) of the train also meets the technical requirements of the speed grade.
Q:Why is the railroad track free of expansion joints now?
One is the long rail itself under all temperature stress, will be locked in the long rail sleepers, which is due to temperature change and contraction, this method is applicable to all the year round temperature of similar areas, for example in the south of Chinese. In some temperature difference regions should take another methods, namely the long rail itself does not bear the temperature stress, and stress or regular bleeding stress to automatic bleeding, make the long rail with temperature rise and free shrinkage, at the time of laying also try to choose the optimum temperature of the rail laying, the expansion value in the minimum range, so that regardless of temperature rise or fall, the rail expansion always control at a minimum.
Q:What are the main functions of nondestructive inspection of rail defects?
In the manufacture of rails, cracks and other defects are easy to occur, and the defects which are difficult to observe by the naked eye are very likely to cause destructive accidents.
Q:Can a track circuit stand between two rails without getting an electric shock?
If the electric two rail, rail, sleeper and ground are insulated, people do not contact track, not electric shock, no "step voltage. If the insulation is not good, the ground has power, it would have to waste much power, is a great waste.
