Realize that Da Muwa wind power is transferred from land to sea

Daeye Special Steel Production Wind Power Special Forging

On September 15th, good news came from Luoxian: The first set of 16 MW platform wind power main shafts bearing made by Dae Metallurgical Steel Materials smoothly went offline. Key components of the fan.

Wind power is clean energy, and its industry plays an important role in achieving my country's "double carbon" goal. As the core component of the wind turbine, the main shaft bearing assumes the function of tolerance and improve the efficiency of fan transmission in the fan. Wind power main bearing is the core connection transmission parts of fan wheels and generators. Due to the complexity of wind power equipment, long life, high reliability, etc., the wind power bearing has high technical complexity. Therefore, its manufacturing not only has a high technical content, but also has a relatively long cycle. The technical requirements for maritime fan bearings are more complicated. In order to reduce risks, the materials need to be specially processed.

In 2015, Daye Special Steel undertakes and completed the national "863" scientific research project --- "Development of Key Technologies for Using Bearing Using Bearing", which laid a solid foundation for the production technology of the domestic high-power wind turbine with bearing steel and bearings. Together with bearing companies and fan companies, the localization of fan bearings from scratch, from scratch to strong, to achieve the development of Da Muwa wind power from land to high -end sea.

According to the research and development technicians of Dye Metallurgical Steel, the 16 MW platform wind electricity main shaft bearing needs to ensure that the performance of the material is improved under larger size conditions, and the bearings have a long life. , Detection and analysis and other capabilities have put forward more stringent requirements.

Speaking of the research and development process of the product, the technical research and development personnel of Da Meantian Steel said that combined with user needs, the use of advanced smelting and forging equipment, the process design of the product's smelting processing and thermal treatment Dimensions of bearing steel purity purification, biased analysis and other series of "card neck" problems. Bearing steel has the characteristics of low -twice tissue tissue, high purity, small analysis, and low oxygen content. Finally, it provides users with high -power wind power high -quality bearing steel Raw materials.

Experts from the China Renewal Energy Society of Renewable Energy Society said that the first domestic set of 16 MW platform wind power main shafts to solve the most critical "card neck" problem that my country's wind power industry has not resolved in 20 to 30 years, and further promotes domestic production Wind power products contribute "China Power" for global response to climate change, solving energy security, and realizing energy transformation.
