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.

Study on Cooling Method of SUP9 Spring Flat Steel

Study on Cooling Method of SUP9 Spring Flat Steel Hot rolled spring flat steel bar is mainly used for the automotive industry, and it’s the raw material for automobile leaf spring  manufacturing. The main varieties of spring steel include 60Si2Mn spring steel,  SUP9 spring steel flat bar , 55SiMnVB spring steel. SUP9 spring steel flat bar is produced in accordance with the Japanese standard. At present, many leaf spring manufacturers mostly use SUP9 spring steel as the raw material for manufacturing automotive leaf springs. Compared with 60Si2Mn, SUP9 spring steel has good hardenability and low decarburization tendency, so the mechanical properties and fatigue properties of the leaf springs produced with SUP9 spring steel are better than that of 60Si2Mn steel. However, due to the good hardenability of  SUP9 steel , the hardness is often too high during actual rolling production and cooling. The reheating, quenching and tempering treatment are carried out in...
