Based on all the advantages and the responsibility of Inner Mongolia's industrial "eldest son", Baosteel continues to play the role of the Inner Mongolia Autonomous Region's industrial "leader", helping Inner Mongolia to build a clean energy output base, with the development and investment of onshore wind power steel containing rare earth refreshing the Baosteel's research and development and investment in onshore wind power steel with rare earth content has refreshed the height of "Baosteel manufacturing" and turned the never-ending "northwest wind" into a constant source of green energy.
　　
Combined efforts to make good use of the two treasures of steel and rare earths
　　
"Baosteel onshore wind power steel containing rare earths is mainly produced by the wide plate production line of Baosteel thin plate plant." Baosteel sheet plant wide plate operations department director Wang Guohai introduced, "Baosteel is one of the earliest domestic steel enterprises to develop wind power steel, and continue to develop in tandem with the wind power industry. Rare earth-containing onshore wind power steel is the key product of Baosteel, and its production and sales volume, quality and delivery time are at the leading level of the industry, and it has a good reputation in Inner Mongolia, Shaanxi, Hebei and other places."

According to Wang Guohai, in order for the wind turbine to run in high wind speed, the tower made of wide thick plate is needed to support the wind turbine. In the wind power steel, the tower steel volume accounts for the largest, 1 1.5 MW wind turbine total steel volume is about 170 tons, of which the tower steel volume is about 120 tons, accounting for up to 70%. Not only that, because the wind turbine tower year-round to withstand high temperatures, extreme cold, sand and other harsh weather tests, wind turbine tower steel welding performance, mechanical structure, low-temperature impact toughness and other performance have harsh requirements, ordinary thick plate manufacturers are difficult to meet.
　　
"Steel with rare earths will be tougher, tougher and stronger!" Wang Guokhai pointed out the absolute advantage of Baosteel in developing onshore wind power steel. The natural rare earth-containing properties give Baosteel onshore wind power steel excellent welding properties, mechanical structure, low-temperature impact toughness and fatigue resistance.
　　
"To this day, wind turbine towers made of Baosteel onshore wind power steel are still standing intact in the wilderness, and still maintain the excellent achievement of zero accidents, regardless of wind and rain, snow and frost." Wang Guohai proudly said, "With the excellent product quality, Baosteel has not only become the product supplier of international wind power giant Vestas, but also supplied a large amount of onshore wind power steel for China's State Grid, State Power Investment, China Datang, China Huaneng and other large central enterprises."

　　During the interview, Wang Guohai mentioned an important equipment in the wind power field - direct-drive permanent magnet wind turbine with NdFeB as the core material. High-performance magnetic material is one of the most important materials for the production of direct-drive permanent magnet wind turbines. This is also the advantage of Baosteel Northern Rare Earth.
　　
"Direct-drive permanent magnet wind turbines take the turbine impeller to directly drive the generator rotation, eliminating the need for a traditional AC-excited doubly-fed asynchronous wind turbine with a speed-increasing gearbox, avoiding the occurrence of gearbox failures and maintenance during operation." Wang Guohai further explained, "Since direct-drive permanent magnet wind turbines are manufactured with rare earth NdFeB permanent magnets, they have the advantages of no excitation winding, simple structure, reliable operation, high power quality, low harmonic components, etc., and have strong low-voltage ride-through capability, which can improve the operation quality and reliability of the power grid, and are very suitable for such areas as Inner Mongolia, where the land is sparse and the wind and sand are severe. It is very suitable for the promotion in Inner Mongolia, which is a region with sparse land and severe wind and sand."
　　
As the leader of China's rare earth industry, Baosteel Northern Rare Earth relies on a series of industrial layout to form the industrial layout of high performance NdFeB magnetic materials in Beijing, Inner Mongolia and Zhejiang, becoming the largest supplier of high performance NdFeB magnetic materials in China and even in the world. "One hand is steel, the other hand is rare earth. The never-ending 'northwest wind' and the rich iron ore and rare earth resources of Baiyun Ebo are the treasures given to Inner Mongolia prairie by God." Wang Guohai said, "Rare earth permanent magnet materials make Baosteel onshore wind power steel products unique in China."
　　
In 2022, Baosteel further adjusts and optimizes the product structure and sales strategy of wind power steel, and strives to release the significant advantage of wind power steel benefits over other varieties of steel. In the first half of this year, Baosteel continued to increase the sales of onshore wind power steel containing rare earth, 438,300 tons of onshore wind power steel products were sold to all over the world, an increase of 128,000 tons year-on-year. In June this year, Baosteel's onshore wind power steel containing rare earths increased efficiency by 8.1 million RMB in a single month, and the total efficiency increase in the first half of the year reached 29,347,500 RMB. Based on the high quality products and strict delivery time, Baosteel's onshore wind power steel products have been consolidated for key users, and the cooperation relationship has become more and more stable, and the percentage of wind power steel purchase sales for key projects and head enterprises reached 59.16% in the first half of the year. Baosteel will continue to increase visits to key sales regions and key users to deepen the partnership, enhance user stickiness, improve variety benefits, and satisfy users and empower the brand with quality services.

 

 

Now, Baosteel onshore wind power steel with rare earth has been successfully applied to the world's most advanced new technology and test demonstration project of flexible DC power grid transmission, comprehensive power supply reliability reached the international advanced level, can realize the green grid full coverage, help the country "double carbon" goal to achieve.
　　
"As one of the four major applications of NdFeB magnetic material, which is on par with new energy vehicles, energy-saving elevators and energy-saving inverter air conditioners, the demand for wind power will grow rapidly. Wang Guohai is full of expectation, "Baosteel onshore wind power steel with rare earth empowerment will be promising and promising in the future."
　　
By combining the two treasures of steel and rare earths together, Baosteel plays a unique advantage to make the former "sky is pale, the wilderness is vast, the wind blows the grass low to see cattle and sheep" grassland interpretation of the "tower high, blade long, wind-blown units busy power generation" scene.
