38 kg rail size parameters
38kg steel rail usually refers to standard rails with a weight of about 38.733 kg per meter. The size parameters of this rail mainly include rail height, rail bottom width, rail head width, cross-sectional area, etc. The specific parameters are as follows:
* Rail height: 134mm
* Rail bottom width: 132mm
* Rail head width: 70mm
* Cross-sectional area: F=42.5cm²
| Parameters of 38kg Heavy Rail | |||
| type | weight (kg/m) | material | length (m) |
| 38kg | 38.733 | 50Mn/U71Mn | 12/12.5m |
| rail height (mm) | bottom width (mm) | head width (mm) | web thinkness (mm) |
| 134 | 114 | 68 | 13 |
These parameters have a vital impact on railway construction and use. The design of rail height and rail bottom width ensures the stability and load-bearing capacity of the rail, while the rail head width affects the contact area between the train wheels and the rails, thereby affecting the stability and driving safety of the train.
In addition, different types of rails have their own specific size parameters. The setting of these parameters is based on the principle of meeting the safety, stability and economy of railway transportation.
Importance of rail size parameters
The size parameters of rails are important considerations in railway construction and use. Reasonable size design can ensure the load-bearing capacity, stability and durability of rails, thus affecting the safety and comfort of train operation. At the same time, different size parameters also determine that different types of rails are suitable for different transportation systems and occasions.
In general, understanding and reasonably selecting the size parameters of rails is crucial to ensure the efficiency and safety of railway transportation. No matter what the size of the rail is, the optimal size parameters need to be determined according to its use environment and needs.
