Ms Light 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.

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 kind of steel should be used for railway rails?
At present, foreign timber rail basically is pearlite steel, while the rail strength can be increased by alloying and heat treatment technology, but is close to the limit, cannot be solved in improving the strength while maintaining good toughness from the root of the problem, more unable to meet the requirements of high speed and heavy haul railway on rail and rail turnout is higher and the technology. Bainitic steel is the invention patent of Professor Fang Hongsheng of Tsinghua University. In 2005, it was coordinated by Baotou science and Technology Bureau to promote cooperation between Baotou Steel and Tsinghua University. It was listed as a key research cooperation project in Baotou. The bainitic rail solves the technical problems of strength, toughness, plasticity and processability simultaneously meeting the requirements. The operation test of Shenyang Bureau, Shijiazhuang Taiyuan line, Beijing Baotou line, Daqin Railway Line in recent years proved that the bainite rail turnout rail turnout than the strength can be increased more than 2 times, the toughness can be increased more than 4 times, life can be increased more than 3 times. In October last year, the Ministry of Railways organized the "railway heavy rail bifurcated rail structure and material optimization research" bidding project, Baotou Steel won the bid at an absolute advantage. The next step is to generalize to curve rail, combined turnout rail and other varieties, and the economic and social benefits will be more remarkable.
Q:Why should there be a gap between the two railway tracks?
Another relatively new way of connecting rails is the continuous welded rail (Continuous, Welded, Rail, CWR), also known as seamless rails or long welded rails. This method couples several kilometers of rails together to form a continuous line. Because there is no seam, the strength of the track increases, less maintenance is needed, and the vehicle runs more smoothly.The cost of welded rails is more expensive than that of a fish board. But because of the high strength, the vehicle can travel at a higher speed on the continuous welded track, and the friction force is reduced.
Q:The tracks on the stones have what effect?
There is one very important point, due to thermal expansion and contraction, the rail in the summer or winter there will be expansion and contraction, so that line crawling up the runway or off track rail, and the stones can well make up for the lack of lines is to prevent and stop crawling up track or off track.
Q:What are the contents of the rail approach?
If you are into the rail welding base, to the selection of rail (rail according to the different choices of different welding tasks), welding inspection (inspection of rail in rail transport process has no damage), before steel rail welding straightening (rail end bend straightening), rust before welding (rail end, rail top surface, bottom of rail welding, prepare welding is left).
Q:How to deal with old rail rail?
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. The rail must provide a continuous, smooth, and least resistant rolling surface for the wheel. In electrified railway or automatic block section, rail can also be used as track circuit.
Q:What is the rail dispersion?
The concrete way is to make all the rail fasteners loose, and use the drum to pad the rail and hit the rail with a rail collision device. When the rail reaches the designed rail temperature, the fastener is quickly tightened and the line is locked. When the rail temperature is lower than the designed rail temperature, the rail pulling device can be used to draw the rail and tighten the fastener.
Q:What is the method of rail butt welding?
The replacement of rail in CWR on the main line and no conditions for pressure welding or contact welding, the general method of aluminium heat welding rail, the disadvantage of this approach is that the solder joint residual impurities and bubbles easily, affect the service life of the rail and road safety, so in the solder joint al heat welding on general drum to install packet fishplate support as external reinforcement joint.
Q:What is the welding method of rail butt joint?
When welding, advance the end to be welded two workpiece fixed in the mould, then the aluminum and iron oxide powder mixture (called thermite) is heated in a crucible, the reduction of the exothermic reaction, become liquid metal (iron) and slag (Al2O3), injection mold. The liquid metal flows into the gap of the joint to form the weld metal, and the slag floats on the surface.
Q:Why should there be a certain gap in the rail connection?
But in the knowledge of the physics of middle school once learned, between the tracks and the track is to leave a little gap, because if you do not leave it in the summer, temperatures fell between the rail and rail mutual extrusion thermal expansion and contraction, causing damage to the road traffic safety hazards.
