Packaging & Delivery of Ms Heavy Steel Rai 50Mn, U71Mn

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

Ms Heavy 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.

5. Delivered by container or bulk vessel

Q:The rails of the high iron welded together as a whole
Seamless welding technology, can make between two rails almost can not see the welding point, natural transition, in the high-speed rail, "bang" sound will become history.
Q:What is the upsetting amount of rail?
Upsetting is the amount of deformation produced during the top upsetting of the two rail to be welded.
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 is quenched rail?
The concrete method is as follows: when the rail or the wheel of the eutectoid component is heated by the high-frequency induction or the flame is heated to 850~900 DEG C, the quenching process is cooled by compressed air or spray. The cooling speed of quench water quenching than the general low, thus obtained the fine pearlite.
Q:What is a rail pile?
The rail is used as the material of the pile foundation to directly push the rail vertically into the ground to the design depth. The superstructure is supported by the friction force between the rail and the surrounding soil and the bearing capacity of the rail top and the bearing soil. Generally used for better soil conditions, buildings are not very large
Q:What kind of rail needs polishing?
Therefore, the rail damage must be eliminated or repaired in time so as to avoid the safety of rail transit operation. These repair measures, such as rail oiling, rail grinding, etc., in which rail grinding due to its high efficiency by the world wide range of railway applications.
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'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:What are the main functions of nondestructive inspection of rail defects?
Even endanger personal safety. Using nondestructive testing, RT, MT, PT and other conventional testing methods, it is easy to find defects that are difficult to observe by the naked eye. Prevent accidents and ensure quality.
Q:Several questions about high speed rail and subgrade.
You said concrete thick plate, should be the track board, that is, the use of ballastless track line, there is gravel laying corresponding to the ballasted track. This has nothing to do with operational safety. Many high-speed rail lines are adopted both at home and abroad, and ballasted tracks are adopted.
