Information

Sleeper screws are the main components of railway tracks. The main material is manganese alloy. The function of the sleeper screws is to guide the wheels of the rolling stock to move forward, withstand the huge pressure of the wheels, and transmit them to the sleepers. The main material of sleeper screws is carbon steel, which has high strength and hardness, high elastic limit and fatigue limit.

Classification of rail damage:
The manufacturer of sleeper screws tells you that rail damage is a serious problem in rail transit, which directly affects the safety and stability of train operation, and is closely related to transportation costs, selection of rail materials, and related design and manufacturing. The sleeper screws manufacturer tells you that the rails need to be supported and guide the locomotive to travel in the prescribed direction. However, during long-term use, rails will suffer damage, such as common breaks, cracks, and other conditions that affect performance. Only by clarifying the rail damage and its causes can the work quality of rail flaw detection be better improved.
Rail nuclear damage
The main reason is that during the process of smelting or rolling, the material used for the rail is relatively poor, or there are defects in the process of use, so that the stress of the locomotive is concentrated under the action of repeated loads, and the source of fatigue continues to increase and expand. . The manufacturer of sleeper screws tells you that rail nuclear damage mainly occurs inside the head of the rail, and as the diameter of the nuclear damage increases, the bearing capacity of the rail will decrease accordingly. Therefore, under the action of high-speed repeated load, the rail is extremely easy to break.
Rail joint damage
This is the weakest link in the line. The wheels of rolling stock constantly act on the joints of the rails, making the maximum inertial force borne by about 55% higher than that of other parts. The manufacturer of sleeper screws tells you that during normal rail flaw detection, screw hole cracks or saddle wear often occur.
Rail longitudinal and vertical horizontal cracks
The longitudinal and vertical cracks of the rail are mainly due to the poor manufacturing process of the rail, and the serious segregation, shrinkage cavity, and inclusions in the steel ingot have not been paid attention to. The sleeper screws manufacturer tells you that after the steel ingot is rolled into a rail, those defects will remain in the rail head, rail waist and rail bottom in flakes, on the contrary parallel to the longitudinal direction of the rail, presenting a horizontal or vertical state.
Rail bottom crack
Developing from the vertical longitudinal cracks at the rail waist downwards, they become cracks at the bottom of the rail. Rust pits or scratches on the bottom of the rail will form transverse cracks on the bottom of the rail. The sleeper screws manufacturer tells you that in the process of manufacturing the rails, the bottom of the rail has defects such as rolling and lack of close contact with the backing plate sleepers, which cause the bottom of the rail to be subjected to great stress, resulting in transverse cracks or ruptures at the bottom of the rail.
