Kiwango cha reli ya chuma ya EN13674-4 utangulizi

19 Mei

EN13674-4 ni kiwango cha Ulaya ambacho kinabainisha mahitaji ya reli za chuma zinazotumiwa katika mifumo ya kufuatilia reli. Kiwango hiki kinashughulikia vipimo vya kiufundi kwa reli za chuma zilizo chini ya gorofa na uzito wa jina kuanzia 27 kg / m kwa 46 kilo/m, and it applies to rails made of rolled steel.

EN13674-4 standard includes various parameters such as rail dimensions, mali ya mitambo, Utungaji wa kemikali, and other quality characteristics. It also specifies the testing procedures that need to be followed to ensure the rails meet the required standards.

EN13674-4 helps ensure that steel rails used in railway track systems are manufactured to a consistent standard, which helps improve safety, Kuegemea, and performance of railway operations.

The EN13674-4 standard covers the technical requirements for flat-bottomed steel rails. These rails have a symmetrical cross-section with a flat base and two sloping sides.

Zaidi ya hayo, the standard defines the rail profile dimensions, which include the head width, Urefu, na unene, as well as the foot width and depth. It also specifies the tolerances for these dimensions and other quality characteristics such as straightness, surface finish, and internal soundness.

EN13674-4 standard specifies the technical requirements for flat-bottomed steel rails used in railway track systems. Here are some of the key specifications covered by this standard:

  1. Rail dimensions: The standard defines the nominal weights of the rails, which range from 27 kg / m kwa 46 kilo/m. It also specifies the rail profile dimensions, including the head width, Urefu, na unene, as well as the foot width and depth.
  2. Mali ya mitambo: The standard sets out the minimum values for various mechanical properties of the rails, such as yield strength, nguvu ya tensile, urefu, and hardness. These properties help ensure that the rails can withstand the loads and stresses imposed by train traffic.
  3. Utungaji wa kemikali: The standard specifies the maximum limits for various chemical elements in the steel used to manufacture the rails, such as carbon, Silicon, Manganese, sulfuri, na phosphorus. These limits help ensure that the steel has the desired properties for rail applications.
  4. Quality characteristics: The standard includes requirements for various quality characteristics of the rails, such as straightness, surface finish, and internal soundness. These characteristics help ensure that the rails meet the necessary standards for safety, Kuegemea, na utendaji.
  5. Testing procedures: The standard specifies the testing procedures that need to be followed to evaluate the rails’ compliance with the required specifications. These tests include visual inspection, dimensional measurements, mechanical testing, and non-destructive testing.

EN13674-4 standard for flat-bottomed steel rails is primarily used in European countries for railway track systems. The rails manufactured in accordance with this standard are commonly used in various applications.

In addition to Europe, some other countries around the world also use the EN13674-4 standard for their rail systems.

EN13674-4 standard is an important reference for the design, manufacture, and maintenance of steel rails used in railway track systems, and it helps ensure that these systems operate safely and efficiently.
