Usages of Steel Heavy Rail 50MN, U71MN, 900A, 110A:

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 50MN, U71MN, 900A, 110A:

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 50MN, U71MN, 900A, 110A:

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.

FAQ:

Q1: Why buy Materials & Equipment from OKorder.com?

A1: All products offered by OKorder.com are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, OKorder.com adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.

Q2: What makes stainless steel stainless?

A2: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

Q3: Can stainless steel rust?

A3: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

Q:What is the upsetting amount of rail?
Top forging is a very important link in the welding process of rails. The link is to increase the feeding force, so that rail rapid delivery, so as to achieve the elimination of debris, eliminate defects, forming a good welding process.
Q:Contact surface between train wheel and rail
Because the wheels of the train all have rims, you can go and have a look at it, that is, a part of the inside of the wheel. The main function of this wheel flange is to guide and prevent derailment. The rim has a very complex profile. The standard requirement is that if the flange of a car is too worn out, it is prone to derailment. The machined flange must be machined to the standard contour.
Q:What is the difference between the rail lead line and the rail connection line?
Shaped rail refers to a complete rail, one end is a rail type, and the other end is another rail type, is obtained by forging process.
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 the welding method of rail butt joint?
In order to adjust the melt temperature and the chemical composition of weld metal and alloy, often adding additives amount in thermites. Thermit welding has the characteristics of simple equipment, convenient operation and no power supply. It is often used in welding of rails, bars and other large section workpieces.
Q:Which companies are the main rail products used in China?
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. The rail must provide a continuous, smooth, and least resistant rolling surface for the wheel. In electrified railway or automatic block section, rail can also be used as track circuit.
Q:How to deal with old rail rail?
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. The rail must provide a continuous, smooth, and least resistant rolling surface for the wheel. In electrified railway or automatic block section, rail can also be used as track circuit.
Q:The hardness of the crane wheel is larger than that of the rail
You have to look at the actual wear and tear situation, because there are many tracks on the market are Q235, and the ordinary steel plate is a model, and there is 55Q's better, but the price is also expensive,
Q:What is the cause of the side or rail end of the rail? If not timely remediation, what will easily lead to consequences?
Simple and straightforward to say: rail by lateral, vertical long-term pressure fatigue, make rail deformation deformation, so that the profile of horizontal widening, that is, fat edge.
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.
