What are the uses of wind power flanges?
Release time：
2023-02-15
Wind power flange, also known as wind tower flange, wind power flange process is: raw material sources refined export flaw plate --> material into the factory by the supervision of the Bureau of re-inspection --> downfeed by a large saw --> raw materials into the heating furnace heating --> punching repeated forging forming --> normalized annealing heat treatment, wind power flange is connected to the tower sections or tower and hub, hub and blade between the structural components, usually using bolted connections.
The material used in wind power flange is low alloy high strength steel Q345E/S355NL, working environment low temperature close to -40℃, withstand wind power up to 12 levels, the heat treatment requirements for normalizing, normalizing process by refining the grain, uniform organization, improve the organization of defects, improve the comprehensive mechanical properties of forging flange.
Normalizing the degree of impact on the organization, the appropriate temperature makes the grain refinement, so as to get good performance. The temperature is too low, the effect is not great, the temperature is too high, the grain is coarse, very easy to form Weiss organization, so that the performance decline. The mechanical properties of the forging flange before and after the improvement of the normalizing process was tested and the organization observation, the results show that the use of appropriate normalizing process can obtain a comprehensive mechanical properties of the flange better.
The process flow of wind power flange is: raw material source refining export flaw plate --> material into the factory by the supervision of the Bureau of re-inspection --> downfeed by a large sawing machine --> raw materials into the heating furnace heating --> punching repeated forging forming --> normalizing annealing heat treatment --> rough machining after heat treatment --> qualified to do fine machining --> geometric size inspection --> finished product packaging and shipment.
