Product Description:

Product Description of Steel Heavy Rail with High Quality for Construction:

Sizes: 38kg, 43kg, 45kg, 50kg, 60kg.

Production Standard: GB2585-81, DIN, AREMA, JIS, BS, UIC, etc.

Material: 50MN, U71MN, 900A, 110A, etc.

Length: 6m-25m according to the requriements of the clients

Usages of Steel Heavy Rail 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 Steel Heavy Rail 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.

Inspection of Steel Heavy Rail with High Quality for Construction:

We will send the MTC of the factory to the clients dirrectly which contain the anlisis of the heat, chemiqul composition, phisical characteristicas, etc.

And our inspectors will arrive at the factory to meke the inspection of the size, length, weight and quantity before the transportation from the factory.

Q:What are the main functions of nondestructive inspection of rail defects?
In the manufacture of rails, cracks and other defects are easy to occur, and the defects which are difficult to observe by the naked eye are very likely to cause destructive accidents.
Q:What is the method to check the straightness of rail?
The measurement accuracy of the latter is up to 0.4 microns /1000 mm. Straightness measurement is mainly to measure the straightness error of cylinder and cone, the guideway of machine tools and other machines, and the straightness error of the workpiece's linear guide surface.
Q:The tracks on the stones have what effect?
When the line state occurs (level. Level. Direction), line maintenance work area workers will be used to track lifting up, then ramming into the gravel at the bottom of the sleeper, the line restored to good condition.
Q:Cause analysis of manganese stiffness in rail
If the addition of manganese 13% is made into high manganese steel, it becomes hard and tough. So people use manganese steel to make wear-resistant machine parts and rails, bridges and so on. Manganese steel is mainly used to withstand impact, extrusion, material wear and other harsh working conditions, the form of damage to wear consumption mainly, part of the fracture, deformation.
Q:What is a shaped rail?
The rail section size adopted by railway track is different. Our country now uses four types of 75kg/m, 60kg/m, 50kg/m, 43kg/m and two types of 45kg/m and 38kg/m that have been eliminated.
Q:Why can't the blue after rail grinding
Blue is produced martensite, which is a kind of brittle microstructure, high magnification can be found between the metal particles Never mind, cannot form a fibrous structure, will cause the brittle fracture of the rail, there is a big security risk.
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:Why high-speed rail tracks are seamless rail will not expand, how to force the expansion and contraction limit?
The tracks are produced by steel mills by special data, and their technical content is not comparable to that of ordinary rails.
Q:What is the difference between Q235B rail and 55Q rail?
The two kinds of material rail is mainly carbon content difference, and the other is brittleness, toughness, tensile strength, impact strength are not the same
Q:Why are some city railways called light rail? What is heavy rail?
At present, the passenger flow of Shanghai's largest public transport facilities, Rail Transit Pearl Line: date of traffic was 729 thousand people, namely the peak stage of one-way traffic of 20 thousand and 400 passengers per hour; forward (to 2020) the daily traffic of 914 thousand passengers per hour, is the peak stage of one-way traffic of 51 thousand and 500 passengers. The train formation is 6, the train running time is 5.5 minutes, and the forward time is 2.1 minutes. Therefore, the Pearl Line of rail traffic should not be called "light rail" strictly, but should belong to Metro system.
