Usages of High Quality Hot Rolled Light Steel Rail for Minas Q235,55Q

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 High Quality Hot Rolled Light Steel Rail for Minas Q235,55Q

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.

Light Rail

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.    

Light Rail

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:Does the crane use the touch wire or the rail directly?
The crane sliding contact line is also called sliding contact line, slip line and safe slip line. The crane slide line is used to power the moving equipment. It consists of two parts
Q:High iron seamless rail is how to solve the problem of the thermal contraction account?
The seamless line is divided into a fixed area, expansion area, buffer, the buffer can be reserved for the large number of rail joints for expansion, expansion area adjacent to the buffer, if the buffer rail gap due to seasonal changes is not enough, the rail to replace the different length in the expansion area to adjust the rail gap.
Q:The difference between small resistance and constant resistance fastener of high speed rail
The second point adopts the tight pull, that is, the fastening of the rail is more firmly fixed on the ballast bed with the new fastener, and the high-speed railway basically adopts the ballastless track technology, and the fastening performance is better than that of the common railway.
Q:What type of rail is the main type used on the railway?
Heavy rail mainly used for 50KG/MRail is divided into two kinds: heavy rail and light rail,Rail specifications are expressed by nominal weight per metre.Heavy rail: rail of a nominal weight greater than 30 kg per meter
Q:Cause analysis of manganese stiffness in rail
In the manufacture of rail, in addition to adding more manganese, in the upper rail, the layer and is contacted with a wheel, but also added another kind of metal, indium, it added to the rail on the part of the hardness of the case, even has some toughness, the train wheel is very important it is time, and the "tire" contact, collision, there will be some flexibility, to ensure the safe operation of the train.
Q:What is the rail temperature stress?
Temperature stress: as a result of changes in temperature, the structure or member produces an extension or contraction, and when the expansion is limited, stress is generated within the structure or member, known as thermal stress
Q:What is the difference between the rail lead line and the rail connection line?
When different types of rail connection section need, because the rail section size is different, need a fishtail splint or rail to rail, or called fish shaped tail splint splint or the connection of different section type profiled rail rail.
Q:Why is rail insulated?
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:High speed rail runs so many trains a day, what about rail wear?
The track is regularly checked and repaired. These are upstairs, in addition, the EMU because the car is light, but also the whole car power, the rail wear is not large, there is no heavy haul trains. What's more, its curves and downhill slopes have been computed without any large downhill or small radius curves. Secondly, high-speed rail or rail lines or, in addition to rail bottom slope on rail surface will advance and regular grinding, in order to form a point of view, the train is running, but can improve the wheel through smoothly.
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.
