With the world's leading casting processing technology, Dalian Heavy Industry has developed the core components of the world's largest wind turbine rotor, greatly improved the product integration molding capacity, and has become the exclusive supplier
of this key component of the 6 MW offshore wind power project of General Electric GE in the United States.
With a diameter of 6.
9 meters and a weight of 40 tons, the core components of the wind turbine rotor are the most difficult to machine in the casting field of thin-walled, large-scale rotating products, not only requiring no structural defects, but also within the diameter range of 6.
9 meters, the center offset cannot exceed 15 microns
.
This product has been trial-produced in many factories in Italy, France and other factories, but it was not successful
due to casting defects.
After receiving this contract, Dalian Heavy Industry Casting Company actively seized this opportunity, and after more than 4 months of efforts, successively conquered the key common technologies that restrict the production of large-scale castings, and achieved a molding, a pouring, and a number of strict joint inspections by GE experts from General Electric and GE in the United States, and obtained bulk orders
.
Dalian Heavy Industry with excellent product quality and reliable delivery cycle, its wind power structural parts product market space rapid improvement, technical level in the world in the leading position, hub, rotor and other casting products have covered all models of large wind power host, users include Vestas, Siemens, Alstom, Shanghai Electric, Dongfang Electric and many other domestic and foreign wind power machine leading enterprises, the market growth rate is more than
30%.
