Why the wind power flange has high technical content
At present, the height of wind power tower is generally 100~170 meters, which is connected by a single tower with a length of 15~30 meters. The connection between two towers is completed by flanges. The weight of the whole wind power tower is 200~400 tons, so there are high requirements for the strength and stiffness of the flange, which is the connection between the towers. The stress load it faces is also more complex, especially the offshore wind power flange needs to adapt to the harsh conditions such as low temperature, offshore wind waves, typhoons, rainstorms, etc.
Because of the particularity of the connecting parts of the wind power flange, its surface quality and dimensional accuracy are required to be high, so this large wind power flange is generally machined by cutting after forging. Large wind power tower flange, with a diameter of 3~8m, is generally made of S355NL or Q355NE and other low alloy high-strength structural steel, and its heat treatment status is normalized rolling or normalizing. Due to the large size of the wind power flange, the large double column vertical lathe is generally used to turn the end face and the outer/inner circle respectively.
