With its world-leading casting processing technology, Dalian Heavy Industry recently successfully developed the core components of the world's largest wind turbine rotor, greatly improved the product integration molding capacity, and became the exclusive supplier
of this key component of the 6 MW offshore wind power project of GE of the United States.
The core power generation components of the offshore wind turbine developed by Dalian Heavy Industry are supporting products of the offshore EDF project built by GE General Electric for Alstom of France, and it is also the largest wind turbine product currently put into commercial operation in the world
.
With a diameter of 6.
9 meters and a weight of 40 tons, this product is the most difficult to machine in the casting field of thin-walled large-scale rotating products, not only requires 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 and France, but it has not been successful
due to casting defects.
Relying on the unique technology and manufacturing advantages accumulated over the years, Dalian Heavy Industry Casting Co.
, Ltd.
has successively overcome the key common technologies that restrict the production of large-scale castings after more than 4 months of efforts, and has achieved a number of strict joint inspections by GE experts of General Electric and GE in the United States, reached quality standards, and obtained batch orders
。 Dalian Heavy Industry Casting Company technical level in the world's leading position, excellent product quality, reliable delivery cycle, the company's production of hub, rotor and other casting products have covered all models of large wind power host, scrap rate of less than 0.
5%, users include Vestas, Siemens, Alstom, Shanghai Electric, Dongfang Electric and many other domestic and foreign wind power machine leading enterprises, the market growth rate of more than
30%.
