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:How do seamless rails solve thermal stress problems?
Seamless line is not entirely seamless, but this gap is pulled very longOrdinary line every 25 meters, one rail seam, seamless rail with long rail and long rail, almost every 1 kilometers to set a rail seam. This rail joint is used to solve the temperature stress as common rail joints
Q:The difference between small resistance and constant resistance fastener of high speed rail
The railway line to solve the rail expansion and contraction method is generally used for fastening the way, is the shrapnel into spring fastener fastener (also called spring bar fastener), rail tightly in the sleepers, forcibly will produce thermal expansion and contraction of the energy to digest, but the existence of such a problem is generated when the thermal expansion and contraction energy is greater than the distance unit of sleeper rail adhesion, makes up the phenomenon of rail, rail sleeper unit length twist. In order to solve this problem, the railway department within a certain distance, playing a few holes in the rail waist to release the energy generated by thermal expansion and contraction, and within a certain distance (about 1500m) retaining rail joint, to assist in releasing the energy generated by the thermal expansion and contraction, in order to solve the problem of rail expansion and contraction. First of all, the first point is that the steel of the rail is not made in China, all of them are imported, and the quality of the rail is guaranteed to the maximum extent.
Q:What is the difference between the rail lead line and the rail connection line?
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:Cause analysis of manganese stiffness in rail
The characteristics of manganese steel are unique. If the manganese in 2-3% is added to the steel, the low manganese steel is as brittle as glass and cracked at the same time.
Q:The tracks on the stones have what effect?
The stones piled together have good elasticity and scatter the vibrations of the train, giving the passengers a sense of comfort
Q:What are the contents of the rail approach?
Is the base of the welded rail or the field of the laying line?.
Q:Name the basic structure and function of the rail
The type of rail is expressed by the mass kilogram of rail length per meter. The rails used in China's railways are 75kg/m, 60kg/m, 50kg/m, 43kg/m and 38kg/m.Has the best bending performance of I-shaped section by section shape of rail, a rail,43G, 50G, 60G rail cross sectionRail, waist and rail bottom three parts. In order to make the rail better withstand the force from various aspects, and ensure the necessary strength conditions, the rail should have enough height, the head and the bottom should have enough area and height, the waist and the bottom should not be too thin.
Q:What kind of rail needs polishing?
Since the main rail surface defects have been eliminated by corrective or transition sanding, then preventive sanding can be carried out. The purpose of this grinding strategy is to eliminate or control the rail surface defects and ensure the rail surface state and good shape. Usually a small amount of metal (0.2~0.3mm) is removed and the grinding time is more frequent or controllable.Preventive grinding is very economical, especially if only a small amount of metal is removed, the use of grinding tools is reduced, and the service life of the rail is maximized.
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 main material of high speed rail?
High manganese steel is one of the main anti-wear materials, and its wear-resistant parts are widely used in metallurgy, mining, power, building materials, railways, coal mines, military industry, energy and other fields.
