Railway Fastener Burr Processing Guide

Railway Fastener refer to tiny metal particles on the surface of the fastener that are burrs.
How the Railway Fastener burr occurs when fasteners are formed during cutting, grinding, milling and other similar chip processing. In order to improve the performance and service life of the fasteners, it is necessary to remove the fastener burrs before using the fasteners. Fasteners are common components on mechanical equipment and are important components, so surfaces, sharp corners and edges need to achieve extremely high metal cleanliness. The main methods for removing burrs are: traditional mechanical processes, grinding, polishing and other processes with different degrees of automation.
Railway Fastener
It is also possible to remove the fastener burrs by a chemical process, so that the quality of the fasteners can be better ensured, and the fasteners are all sequentially immersed in a plurality of containers, one of which contains a chemical solution. With a simple soaking process, all burrs can be removed, making the surface smooth and smooth, and the edges are smooth, giving users unprecedented quality. Chemical deburring is not only environmentally friendly but also saves a lot of production and personnel costs.
Three major issues to be aware of fastener maintenance
Although the fasteners are small, they have a great effect. The use of fasteners requires regular maintenance to ensure safer use of the fasteners, and can extend the service life of the fasteners and improve the performance of the mechanical equipment.
As a Railway Fastening System Manufacturer, when we are maintaining fasteners, there are three main problems:
1. When the fastener is quenched, the silicate cleaning agent should be used to clean the impurities, and then carefully rinsed to avoid residual impurities on the fastener, which affects its normal application.
2. After the fastener is tempered, its color may change. After the fastener is soaked in the ether for a period of time, oily substance will be produced. When this happens, the fastener is indicated. Not clean enough. After the analysis, it will be found that the stacking is not very reasonable when heating the fasteners, and the fasteners may have some small oxidation in the quenching oil.
3. If there is a white substance on the fastener, it is likely to be some phosphide. The reason for this phenomenon is that there is no cleaning with an acid cleaner, and it is not careful enough to check the rinsing tank.
The above problems must be taken seriously, which will directly affect the performance of the fasteners, and may also lead to a shortened service life of the Railway Fastening System, causing early damage of the fasteners.

Tension Clamp Is Important

图片
With the increase of the axle load of the railway locomotive and the improvement of the running speed of the train, as well as the development of the urban rail transit and the subway, the Tension Clamp  is also becoming a key link in the continuous development of the track structure, which is concerned by all the countries. In the general line, the need is about buckle pressure, good elastic spring, to meet the needs of heavy-duty, high-speed lines, while in the viaduct track seamless circuit, in order to reduce the interaction between the rail and the bridge, we have to ensure the elasticity that is enough, if the train goes through, the loss of undercover cushion due to compression caused by the buckle pressure is small, and fasteners of  Railway Fastening System  do not loose. Although it is a small public work device, but it is an important part of the track, because of its large demand, about 7000 per kilometer, its reliability is directly related to the safety...

Pay Attention to Rail Plate Base Pad

图片
As an indispensable part of the railway, the  Rail Plate Base Pad  plays an important role on the railway. If it falls off, which will influence the whole  Railway Fastening System  deeply. In the high-speed railway subgrade, the separation of the slab Rail Plate Base Pad will reduce the track strength. This situation means the stiffness and service life of the track will be reduced directly. It causes the rail plate base pad to crack and disconnects from the lug time. The pressure of the top surface of subgrade increases with the length of abscission. Meanwhile, the trend of increasing is becoming more and more obvious.

Do You Know Heavy Haul Rail?

图片
The first International Heavy Haul Congress in 1978 was held in Perth, Australia. Since the establishment of the International Association of Heavy Haul Transport in 1985, the definition of heavy railroads has evolved with heavy loads and advancing with the time. In 2005, the International Association of Heavy Load Associations proposed a new heavy haul railway standard that required to meet at least two of the following three conditions: 1.train traction quality is not less than 8000t 2.vehicle axle in the vehicle reach or exceed 27t 3.The length of the line is not less than 150 km, the annual freight volume is not less than 40 million tons. We support several types of  Rail Fastening System  to meet the different rail's requirements.
