Analysis of Quenching Process of rail joint bar

A rail joint bar, (track joint bar, also known as fish plate), is the recommended product for rail joint connection. Divided into light rail, heavy rail, and crane rail.

The rail joint bar is also called the fish plate, which plays a role in fixing the rails on the railway. According to different rail applications, the type of plywood used is also different, so that the role of the plywood can be further brought into play. In fact, in order to enhance the role of the plywood, some quenching processes are often used after the plywood is produced. In order to increase the understanding of the quenching process. Let’s take a look at the plywood quenching process. Track plate manufacturers

The heat treatment process is very important in the production of rail joint bar. This research mainly focuses on the self-tempering process of the quenching heat of the fish plates. The following are the results of the study: different cooling rates, different water inlet methods, and different quenching medium residence times, these factors all lead to different organizational properties. In the quenching process, the cooling rate is inconsistent, and the temperature drop is relatively stable during the temperature drop. The cooling rate of the waist is uniform, while the cooling rate of the small waist is inconsistent, resulting in that its microstructure and mechanical properties being lower than those of the large waist. up. Comparing the two different ways of entering the water in the self-tempering process of quenching residual heat, it can be concluded that since the water depth of the waist up is higher than that of the waist down, the temperature drop rate of the water entering is slower, the structure is stable and the strength is higher, and the microstructure is uniform and stable. , Excellent mechanical properties.

In summary, it is the rail joint bar quenching process. It is understood that these will further play the role of the fish plate in practical applications in the future.
GloryRail supplies many types of railway accessories such as rail clips, fishplates, and mine accessories. The quality is good, and damages during use are rare.

Principle of rail clamp design

Principle of rail clamp design rail clamp design The rail clamp design has several functional features: 1. Adjustability: The adjustable length is 15mm, and its adjustability functions include: (1) The rail presser is easy to install, saves time, and has high precision (2) The track can be adjusted if the structure of the support beam is slightly changed. 2. Anti-loosening: Under the action of the lateral force of the track, through the force analysis of the welding RTYB, a part of these lateral forces are transmitted to the bottom seat through the upper cover plate as the pressure of the bottom edge to seat on the upper cover plate. The other part is the lateral friction between the base and the upper cover. Since the wedge-shaped action between the base and the upper cover plate is converted into the tightening force of the bolts, it has an anti-loosening effect. 3. Self-locking: The three pieces are self-locking together through the interaction of the upper cover, the base, and the

What is rail creep

What is rail creep rail creep Rail creep is also known as line crawl. The creeping phenomenon of the rail along the longitudinal direction of the line. With the increase in railway transportation tasks, the impact of the wheels on the rails when the train is running accelerates the creep of the rails. Rail creep can cause many diseases of the line. In order to prevent the occurrence of track creep diseases, it is necessary to find out the real cause of creeping in order to effectively eliminate the problem. There are two different manifestations: the rails move along the soft sleeper surface due to insufficient fastening pressure of the fasteners; the longitudinal movement of the row is caused by insufficient ballast bed resistance. The reason for this is the longitudinal force of the rail caused by the wheel rolling and longitudinal slip, train braking, the change of rail temperature, and the creep caused by the deflection and deformation of the rail under the action of the wheel load
