Usages of Hot Rolled Steel Rail

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

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.

Packaging & Delivery of Hot Rolled Steel Rail

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

steel rails delivered

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.

Q:55Q rail performance
This is the main rail material of different carbon content, the other is brittle and ductile tensile strength and impact strength are not the same, 55Q rail material is mainly used for mine rail, and Q235 is more commonly used, but cheaper
Q:High iron seamless rail is how to solve the problem of the thermal contraction account?
The rail temperature force is used on the railway line to lock the track with strong line resistance, which limits the free expansion of the rail. In our country, we use high strength bolts, gusset fasteners or elastic fasteners to restrict the rail. In order to reduce the temperature force of the rail, the line should be locked when the rail is at the right temperature. The local maximum rail temperature is used to lock the rail temperature with the lowest rail temperature above the average height.
Q:Why is there a gap between each rail on the railway?
In summer, the rails are heated and inflated, leaving gaps to prevent accidents. In winter, the tracks freeze and leave gaps to prevent broken rails, and the gap can act as a general solution.
Q:What is the connection of the rail joint?
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:What kind of rail needs polishing?
Corrective sanding (defect grinding) (Figure 2)The main purpose of this strategy is to eliminate or reduce grinding defects on line rail, generally use the active grinding process, pre designed grinding amount (0.5mm to 4-6mm), and the interval is relatively long, usually by the severity of the defect to decide.Corrective grinding is not very economical, mainly because of the need to remove a large amount of metal on the rail surface, and also requires a large number of grinding processes to reduce the potential service life of the rail. But to ensure that the rail will not fail in a short time, corrective grinding is necessary, especially during the period when the budget for replacing rails is tight. However, this condition of the rail may cause the train speed limit.
Q:How to repair welding rail?What kind of electrode is used in rail welding? What's the problem easily?
Repair welding is found when pitting corrosion pits local rail surface, affecting the smooth operation of the train, but the rail has not reached the need to replace the degree, can be used in welding repair: first by flame heated to a certain temperature, and then use the welding welding, using heat to control the cooling speed. When reduced to a certain temperature. The grinding wheel along the longitudinal smoothing.
Q:What is the rail of the railway?
Also, in the upper rail, the layer and is contacted with a wheel, is adding another 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 and the "tire" contact, the collision, there will be some flexibility, to ensure the safe operation of the train.
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:What are the three types of rail damage?
Rail damage has always been a key problem in railway transportation. The main damage types are rail crush, side wear, corrugation and delamination, accounting for more than 80% of the rail damage.
Q:What is the material for railway track
The railway tracks are made of steel and can be divided into ordinary manganese containing rails, copper containing plain carbon steel rails, high silicon copper bearing steel rails, copper rails, manganese rails, silicon rails, etc..
