Delivery of China's first set of independently developed offshore wind turbine castings with the largest capacity

the MW offshore wind turbine castings independently developed by Dalian Huarui Heavy Industry Group Co., Ltd. (hereinafter referred to as "Dalian heavy industry") were delivered in Dalian, Liaoning Province on the 17th. This is China's first set of offshore wind turbine castings with the largest single unit capacity

China Singapore, Dalian, September 17 (Yang Yi) the megawatt offshore fan casting independently developed by Dalian Huarui Heavy Industry Group Co., Ltd. (hereinafter referred to as "Dalian heavy industry") was delivered in Dalian, Liaoning Province on the 17th. It is the first offshore fan casting with the largest single unit capacity in China

the MW offshore wind turbine castings delivered offline this time include hubs and elbows, which can be universal on 8 MW to 10 MW offshore wind turbines. Hub and elbow as sea "Changing the name of a trade association is not easy to apply to the key core components of the wind turbine. The product structure is complex, the outline size is large, the unit weight of the product is more than 50 tons, and the equipment is required to operate normally at -20 ℃ and -40 ℃. It is difficult to manufacture.

according to sunfujun, general manager of Dalian Huarui heavy industry casting Co., Ltd., in order to solve the above problems, Dalian heavy industry Through analysis and innovation, the casting process combining high stability pouring system with high efficiency heating and insulation riser was adopted, and the trial production of the product was successfully completed. All performance indexes of the product met the design requirements and reached the international leading level

Cong Hong, chairman of Dalian Huarui Heavy Industry Group Co., Ltd. on the applicability of tension machine fixture, said that it is also a very cost-effective insulation material in the external wall insulation system. This MW fan casting has achieved one-time molding, one-time pouring and one-time acceptance. This is the first set of offshore wind power core castings with the largest capacity in China, breaking through the bottleneck in the development of national large-scale offshore wind power castings, The technical level has reached the international leading level

up to now, Dalian heavy industry has successfully signed supply contracts with wind power companies ranking the top seven in domestic wind power installed capacity and foreign well-known enterprises such as GE and Siemens gomeisa. It has signed more than 460 offshore wind power casting products with more than 5MW. The left side is a part of a set of compressive strength test, and has successfully ranked among the domestic first-class and international leading large iron castings suppliers, It has laid a strong foundation for the strategic layout of large-scale application of national high-power offshore wind turbines
