What is the wind flange used for?

The wind power flange is a structural element that connects each section of the tower or between the tower and the hub, or between the hub and the blades. It is generally connected by bolts.

The wind power flange is simply the flange of the wind turbine. Wind power flange is also called wind tower flange. Its process flow mainly includes the following steps:

1. Source of raw materials, refining and export of flaw detection plates

2. materials enter the factory re-inspected by the county technical supervision bureau

3. The material is cut by a large sawing machine

4. The raw materials are heated in the heating furnace.

5. Top punching is repeated Forging and forming

6. Normalization, annealing and heat treatment

7. p>8. Fine machining after passing the test

Detailed information:

Principle of wind flange:

The material used in wind power flange is high strength low alloy steel Q345E/S355NL, the lowest temperature in the environment working temperature is close to -40℃ and the maximum wind resistance can reach level 12. The heat treatment requirement is normalizing. The normalizing process refines the grains, standardizes the structure, improves structural defects and improves the quality of the forged flange.

The degree of standardization has a great influence on the structure. The appropriate temperature can refine the grains and achieve good performance. If the temperature is too low, the effect will be insignificant; if the temperature is too high, the grains will become coarse and a Widmanstatten structure will easily form, reducing performance.

Mechanical properties testing and organizational observation were carried out on the standard processmalization of forged flange before and after improvement. The results show that a flange with better comprehensive mechanical properties can be obtained using an appropriate normalization process.
