Just after the beginning of autumn, the vast Damao Grassland in Inner Mongolia is still a scene of vitality. Between the blue sky and the grassy meadows, milky white wind turbines stand, looking like toys like "windmills" from a distance, and like "Optimus Prime" from a close look, which is very huge and spectacular.
At the 2022 Beijing Winter Olympics held earlier this year, the practice of 100% use of "green electricity" in the Winter Olympics venues left a deep impression on the world. Among them, Baotou Steel has supplied 48700 tons of rare earth containing wind power steel for wind power construction in Zhangjiakou competition area, and used green steel to help the Beijing Winter Olympics "move forward together".

As a kind of clean renewable energy, wind power, with its huge reserves, good environmental benefits, short construction cycle, flexible installed capacity, low operation and maintenance costs, and conducive to diversification of energy production, has attracted more and more attention around the world. With the deepening understanding of clean energy at home and abroad, the policy, technology, land and other issues facing the development of wind power in China have been gradually solved. Especially in the "Fourteenth Five Year Plan" period, wind power, as a new energy that has achieved parity, ushered in a long-term stable and healthy growth.
Baotou Steel Wind Power Steel Transforms Grassland Wind into Green Energy
The outline of the "Fourteenth Five Year Plan" clearly proposed that nine clean energy bases and five offshore wind power bases should be built, which has brought huge space for the development of China's wind power industry. As an important component of the nine major clean energy bases, Inner Mongolia is sparsely populated, with a wide distribution, good stability and easy development of wind energy. It is the most abundant area of onshore wind energy resources in China, and its wind energy resource reserves and technology exploitable amount rank first in the country. As early as the end of 2015, the installed capacity of wind power in Inner Mongolia reached 22.5616 million kilowatts, surpassing the installed capacity of the Three Gorges Hydropower Station on the Yangtze River. The "Three Gorges of Wind Power" has risen in Inner Mongolia grassland.

In North China, "Jiziguan" of the Yellow River and Hebei North Wind Power Base, Baotou Steel's onshore wind power steel market share remained above 30%. In particular, in the "few" bend area of the Yellow River, Baotou Steel's onshore wind power steel market share exceeded 90%. In the northwest area on the other side, Baotou Steel's onshore wind power steel brand is quite famous in the local area, and its products account for "half of the country" in the regional market. In 2019, Baotou Steel's onshore wind power steel sales reached 534000 tons, accounting for about 20% of the national market share. In 2020, Baotou Steel's onshore wind power panels will sell well nationwide, with the sales volume reaching 819100 tons. In 2021, Baotou Steel's onshore wind power steel will occupy 1/4 of the domestic market share, and the market share will steadily increase.

Based on various advantages and the responsibility of the "eldest son" of Inner Mongolia's industry, Baotou Steel has constantly played the role of the "leader" of the industry in Inner Mongolia Autonomous Region to help Inner Mongolia build a clean energy output base. With the R&D and investment of onshore wind power steel containing rare earth, it has refreshed the height of "Baotou Steel Manufacturing" and turned the inexhaustible "northwest wind" into a continuous source of green energy.
Jointly make good use of the two treasures of steel and rare earth
"Baotou Steel's onshore wind power steel containing rare earths is mainly produced by the wide and thick plate production line of Baotou Steel's thin plate plant," Wang Guohai, director of the wide and thick plate operation department of Baotou Steel's thin plate plant, said, "Baotou Steel is one of the earliest steel enterprises to develop wind power steel in China, and continues to develop synchronously with the wind power industry. Land wind power steel containing rare earths is a key product of Baotou Steel. Its production, sales, quality and delivery date are at the leading level in the industry, and it has a good reputation in Inner Mongolia, Shaanxi, Hebei and other places."

According to Wang Guohai, in order to enable the wind turbine to operate at a high wind speed, a tower made of wide and thick plates is needed to support the wind turbine. Among the wind power steel, the steel consumption of the tower is the largest. The total steel consumption of a 1.5MW wind turbine is about 170 tons, of which the steel consumption of the tower is about 120 tons, accounting for up to 70%. Not only that, because wind power tower is subject to high temperature, extreme cold, sandstorm and other severe weather tests all year round, the steel used for wind power tower has strict requirements for welding performance, mechanical structure, low-temperature impact toughness and other properties, which is difficult for ordinary thick plate manufacturers to meet.
"If the steel contains rare earth, it will be stronger, tougher and stronger!" Guoguohaido has the absolute advantage of Baotou Steel in developing onshore wind power steel. The characteristics of natural rare earth make the onshore wind power steel of Baotou Steel have excellent welding performance, mechanical structure, low temperature impact toughness and fatigue resistance.
"Up to now, the wind power tower made of onshore wind power steel of Baotou Iron and Steel Co., Ltd. is still standing intact in the wilderness. Despite the wind, rain, snow and frost, it still has the excellent performance of zero accidents." Wang Guohai said proudly, "With excellent product quality, Baotou Steel has not only become the product supplier of Vestas, an international wind power giant, but also supplied a large amount of onshore wind power steel for China's State Grid, State Power Investment Corporation, China Datang, China Huaneng and other large central enterprises."

During the interview, Wang Guohai mentioned to the reporter of China Metallurgical Daily an important equipment in the field of wind power - a direct drive permanent magnet wind generator with NdFeB as the core material. High performance magnetic material is one of the most important materials for direct drive permanent magnet wind turbine. This is also the advantage of Baotou Steel North Rare Earth.
"The direct driven permanent magnet wind turbine adopts the fan impeller to directly drive the generator to rotate, eliminating the speed increase gearbox required by the traditional AC excitation doubly fed asynchronous wind turbine, and avoiding the gearbox failure and maintenance during operation." Wang Guohai further explained that, "As the direct drive permanent magnet wind turbine is made of rare earth NdFeB permanent magnet, it has the advantages of non excitation winding, simple structure, reliable operation, high power quality, less harmonic components, and strong low voltage ride through capability, which can improve the operation quality and reliability of the power grid. It is very suitable for promotion in such sparsely populated and heavily sandstorm areas as Inner Mongolia."
As the leader of China's rare earth industry, Baotou Steel North Rare Earth has formed the industrial layout of high-performance NdFeB magnetic materials in Beijing, Inner Mongolia, Zhejiang and other places relying on a series of industrial layout, 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 inexhaustible 'northwest wind' and the rich iron ore and rare earth resources in Baiyunebo are the treasures bestowed by heaven on the Inner Mongolia prairie." Wang Guohai said, "Rare earth permanent magnetic materials make Baotou Steel's onshore wind power steel products unique in China."
In 2022, Baotou Steel will further adjust and optimize the product structure and sales strategy of wind power steel, and strive to release the significant advantages of wind power steel over other types of steel. In the first half of this year, Baotou Steel continued to increase the sales of onshore wind power steel containing rare earths. 438300 tons of onshore wind power steel products were sold to various regions, an increase of 128000 tons year-on-year. In June this year, Baotou Steel's onshore wind power steel containing rare earth increased its efficiency by 8.1 million yuan in a single month, and the cumulative efficiency in the first half of the year reached 29.3475 million yuan. Based on high-quality products and strict delivery time, Baotou Steel's onshore key users of wind power steel products have been consolidated, and the partnership has become more stable. In the first half of the year, the purchase and sales of wind power steel for key projects and leading enterprises accounted for 59.16%. Baotou Steel will also continue to increase its visits to key sales regions and key users, deepen cooperation, enhance user stickiness, improve variety efficiency, and satisfy users with quality services and empower brands.
Today, Baotou Iron and Steel Group's rare earth containing onshore wind power steel has been successfully applied to the world's most advanced new flexible DC grid transmission technology and test demonstration projects. The integrated power supply reliability has reached the international advanced level, which can achieve full coverage of the green grid and help the country achieve its "double carbon" goal.
"It can be predicted that as one of the four major fields of application of neodymium iron boron magnetic materials, which are equally famous with new energy vehicles, energy-saving elevators and energy-saving variable-frequency air conditioners, the demand in the wind power field will usher in rapid growth." Wang Guohai is full of expectations, "the onshore wind power steel of Baotou Steel with rare earth enabling will have broad prospects and a promising future."
By combining the two treasures of steel and rare earth, Baotou Iron and Steel Co., Ltd. has given play to its unique advantages, making the prairie of the past "the sky is vast, the wild is vast, and the wind blows the grass, and the cattle and sheep are seen when the grass is low" a scene of "the tower is high, the blades are long, and the wind driven units are busy generating electricity".
