Wind turbine anchor plate for foundation has 2 parts: upper and lower anchor plate (embeded and template ring), which are connected by splice plates and high strength anchor bolts.
Splice plate is a kind of rectangle plate which has the same mechanical properties of anchor plate, usually wind turbine foundation requires anchor plate with large diameter, compared with manufacture anchor ring plate in hot rolled method, use splice plate and seperate parts of anchor plate is more economical option.
Anchor Plate Production Process
According to the plan to buy steel plate (Q345E) → Rraw material re-inspection → Cutting (CNC programming, flame cutting) → Leveling → inspection → opening groove → cleaning and polishing → anchor plate group for tailor welding → inspection (100% ultrasonic flaw detection) → Cleaning Grinding → Appearance inspection → Leveling → Flatness Detection→ Machining → Inspection → CNC Drilling → Inspection → Sand blasting → Anti-corrosion treatment → Inspection → Packaging → Storage.
