Characteristics and Improvement of Steel Rail

图片
As the speeds of  Railway Rail  and axle loads continue to increase, this also requires  Steel Rail  to have greater stiffness and better wear resistance. Steel Rail In order to make the rails have sufficient twist, the rail height can be appropriately increased to ensure that the rail has a large horizontal moment of inertia. At the same time, in order to make the rails have sufficient stability, it should be as wide as possible when designing the width of the rail. In order to optimize the stiffness and stability, countries usually control the ratio of the rail height to the bottom width when designing the rail section, ie H/B. Among them, improving the rail head section design is one of the methods to improve the stiffness and wear resistance. In the early rail section of the rail, the tread surface is relatively flat, and the arcs with smaller radius are used on both sides. Until the 1950s and 1960s, it was found that regardless of the shape of the...

What Is The Type And Specification Of Angle Bar?

图片
Angle Bar  is mainly divided into two types: equilateral angle bar and unequal angle bar. Among them, unequal angle bar can be divided into two types: unequal width and unequal thickness. Angle Bar The specifications of the angle bar are expressed by the dimensions of the side length and the side thickness. At present, the specifications of domestic angle bar are No. 2-20, and the number of centimeters of the side length is the number. The same angle bar often has 2-7 different side thicknesses. The imported angle bar indicates the actual size and thickness of the two sides and indicates the relevant standards. Generally, the angle of 12.5cm or more is a large angle bar, and the medium angle bar is between 12.5cm and 5cm. The side length bar is widely used in various metal structures, bridges, machinery manufacturing and shipbuilding, various building structures and engineering. Structures, such as house beams, bridges, transmission towers, lifting and transporting machi...

What's the Role of Railway Fasteners?

图片
Railway Fasteners  are the parts of the track used to join the rails and sleepers, also known as intermediate joint parts. Its function is to fix the rail to the sleeper, maintain the gauge and prevent the longitudinal and lateral movement of the rail relative to the sleeper. Railway rail fastener systems are divided into: shrapnel fastener system, gusset fastener system, and elastic strip fastener system. Railway Fasteners Although the construction of  Railway Rail  is inseparable from the role of railway fasteners, the strength of some ordinary railway fasteners cannot adapt to the vibration of high-speed rail. Railroads such as railways and subways require high-strength railway fasteners. As the construction of railways continues to increase, our demand for high-strength railway fasteners will also increase rapidly. Railway rail joints are the source of vibration. In order to overcome this vibration source and reduce the occurrence of rail joints, the us...

Technical Requirements Of The Elastic Clip Fastening System

图片
Here is  Rail Accessories Manufacturer  talking about Technical requirements of the elastic clip fastening system. Technical requirements of the elastic clip fastening system An ideal elastic fastening system should be able to meet the following requirements: Elastic  Rail Clip  fastening system should provide sufficient elasticity to absorb the vibrations and shocks caused by moving loads. Elastic clip fastening should have adequate toe load which should not reduce under service. Elastic clip fastening should be of “fit and forget” type to require the least maintenance. Elastic clip fastening should be of the type that it can be used and reused without losing its properties. Elastic clip fastening should have as few parts as possible, which are easy to be manufactured, laid and maintained. Elastic clip fastening should be of the type that it cannot be taken out and as such is free from sabotage or theft. Elastic clip fastening should be of the...

Functions Of Track Ballast

图片
Here is  Rail Accessories Manufacturer  talking about Functions of track ballast. In fact, the track ballast serves a number of purposes.  First of all, it makes sure that tracks stay in place when super-heavy trains roll by on them. It also plays an instrumental role in keeping any vegetation in check that might grow around the tracks (and make the ground beneath the tracks weaker).  Another important aspect of  track ballast  is that it seals out any water that may be around the tracks to actually reach the tracks on a regular basis. That doesn’t mean the ballast completely insulates the tracks from water, which would be impossible, but it does facilitate water drainage around and beneath the tracks so that water doesn’t stay near the tracks and compromise the solidarity of the ground.

Why Specially Those Stones?

Here is  China Standard Heavy Steel Rail Manufacturer  talking about Why Specially Those Stones. If you have any idea about it, welcome to contact us and discuss. It’s not like the construction crews put just any stone they find around the  tracks . That wouldn’t do the trick. For instance, if you put smooth, round pebbles in the ballast, then they might roll or slide over each other when a train passes over the tracks; therefore, they would fail at their main job – providing solidarity to the tracks. Given that fact, you need stones of a specific type that won’t move around too much, except by kids chucking stones near the tracks, of course! In order to guarantee that the stones stay in place, they use sharp and edged stones in the ballast.

What Is Track Ballast?

Here is a  Steel Rail Supplier  talking about What Is Track Ballast. If you have any idea about  Steel Track , welcome to contact us and discuss. Traveling by train is an amazing experience in fast-paced city life nowadays. You get to witness the stunning vistas of nature, sprawling fields, cities teeming with people, or endless stretches of land with no sign of any life whatsoever. One more thing that you almost always see throughout your train-journey are those small stones lying alongside the track on which your train races. Have you ever given any thought as to why there are almost always stones alongside a rail track? What is track ballast? To start with, the stones that you see lying close to the railway tracks are collectively called track ballast. It basically forms the trackbed on which the rail sleepers are kept. Track ballast is packed between the sleepers, in the areas below, and on the sides of railway tracks. I can already hear the question begi...
