Usages of Light Steel Rail Q235, 55Q with High Quality for Construction:

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 Light Steel Rail Q235, 55Q with High Quality for Construction:

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.

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's the difference between a high - speed rail and an ordinary railroad track?
1, ordinary rail each section of 25 meters long, weighing about 1.5 tons, laying completed, the tracks will leave a gap between. In the process of running train, passengers at a distance will hear "Da Da" sound, this is the train to the crash of the welding point.2, high-speed rail line from a single length of 500 meters of rail laying, all of the ballastless track, the entire line level error of not more than 0.1 mm. While the train is moving at full speed, passengers will not hear "click".
Q:What are the reasons for the development of rail nuclear injury?
Because of the rapid increase of railway speed, heavy load and annual volume, rail damage is aggravated, especially in the songThe rail line, the line in a very short time because of head injury may produce a nuclear line.
Q:Will seamless rail expand and shrink?
Yes, that's the law of matter. When heated, the distance between molecules increases, the rail will stretch, and the same cold will shrink.Seamless rail is actually 25 meters rail welded into 1000 meters long rail, paved with local temperature.
Q:What is the function of a railway joint connection part?
The intermediate connecting parts, also called fasteners, have different combinations according to the different types of sleepers used. The wooden, including ordinary spike and iron plate. The advantage of this kind of fastener is less parts, easy installation, but little effort. In order to improve the performance of wooden, many countries use screw spike or spring instead of ordinary spike spike, or use a variety of different types of fastener on the concrete sleeper has been effective. The concrete sleeper fastening, including anchor bolts, iron plate, fastening piece and an elastic cushion (a) anchor bolt. For fastening fastening parts by anchoring various methods. The use of China on the railway is a sulfur anchor mix of sulphur, sand, cement and wax mixture is melted into colloid, injected into the reserved hole in the sleeper, as the fixed anchor bolt medium, pulling resistance, durability and insulation performance are very good. (b) iron backing plate. The utility model can disperse the vertical pressure of the rail, and after adding the shoulder, the transverse force transmitted by the rail can be partly taken, but because the compressive strength of the concrete sleeper is very large, the utility model can not be arranged in general. (c) fastening parts. There are two types of rigidity and elasticity. Rigid fastening parts mainly for buckle type; elastic fastening parts are spring and bar use plate elastic strip type two. (d) elastic cushion. When the train passes, the utility model can buffer and reduce vibration, and can improve the insulation performance of the concrete sleeper. Rubber backing plate, plastic backing plate, cork rubber backing plate and wood backing plate etc., and rubber backing plate is the best.
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.
Q:What is the method of rail butt welding?
Common Rail Rail butt joint, generally use fishtail board connection.Seamless rail bonding in the factory under the conditions of general use of air pressure welding or contact welding, the advantage of this is that there are relatively few impurities inside the solder joint, rail more stable.
Q:What is the rail temperature stress?
Thermal stress is also called thermal stress". Stress due to the temperature rise and fall of a body or the temperature of each part of an object. For example, the workpiece is welded by the stress caused by local heating; there is a gap between the rails of the rails to avoid or reduce the possible temperature stress.
Q:High speed rail runs so many trains a day, what about rail wear?
The rail is made of high manganese steel.Manganese iron is very eccentric and interesting: if 2-3% manganese is added into the steel, the resulting low manganese steel is as brittle as glass and cracked at one stroke. However, if manganese is added to >13% to make high manganese steel, it becomes hard and tough.
Q:What are the requirements of the two rails on the track?
At that level, the same section of line about two shares of the top surface of the rail height difference; line to line tolerance of 4mm, the other line is 6mm.
