If we say that "natural rare earth steel in steel" is a highly covered property of steel products in our country, then "stronger, tougher and stronger" is a comprehensive description of the characteristics of rare earth steel in our country.
Recently, the Chinese Academy of Sciences Institute of Metal Information show that under the premise of basically not increasing the cost of steel production, adding a certain amount of rare earth elements in the steel, can significantly improve the toughness and wear resistance of steel, heat resistance, corrosion resistance, this Rare earth steel purification technology significantly improved the quality of steel, and promote China's steel industry into the high-end global value chain.
Rare earth is known as "industrial vitamins", rare earth steel is a steel containing a certain amount of rare earth elements such as lanthanum, cerium, rare earth elements can significantly improve the toughness of steel and wear resistance, heat resistance, corrosion resistance, after its application Technology is the long-standing unsolved problem in China's steel industry.
In the recent 20 years, the application of rare earth elements in steel has received the great attention and strong support from the relevant state departments. China has rich rare earth resources and the steel output ranks first in the world, which provides a solid foundation for the development of rare earth steel. At present, China has developed a series of products, including copper and phosphorus weathering steel, manganese and niobium series of low-alloy high-strength steel, X series pipeline steel, heavy rail steel, gear steel, bearing steel, spring steel, die steel, construction machinery steel, low Carbon micro-alloy deep-drawn steel, stainless steel and heat-resistant steel, including more than 80 rare earth-containing steel.
Baotou Steel Group has achieved tangible results in technological innovation of rare earth steel. Baotou Steel to promote "rare earth" as the center of the transformation and upgrading, production of high value-added features steel products, will achieve sales revenue of 126 billion yuan in 2020 to create the strongest, world-class leader in rare earth industry, the world's best rare earth Steel production base, go all out to lead a new road to industrialization. At present, Baotou Steel Rare Earth Steel, including high-speed rails, seamless steel pipe has been widely used in national key projects and along the "Belt and Road" exported to 25 countries abroad.
The "13th Five-Year Plan" period is the critical period for China's rare earth industry to upgrade and improve its efficiency. The "Development Plan for Rare Earth Industries (2016-2020)" issued by the Ministry of Industry and Information Technology states that taking the opportunity of the implementation of the "China-made 2025" national strategy and implementing the requirements of the "State Council's Opinions on Promoting the Sustainable and Sound Development of Rare Earth Industries" Based on the key areas of "Made in China 2025" with high relevance to the rare earth industry, we will vigorously develop the high-end rare earth applications and accelerate the transformation and upgrading of the rare earth industry.
With the "Made in China 2025" plan put forward, the strategic goal of making a strong nation has put forward higher and more urgent development requirements for its basic industries - materials manufacturing. The traditional material research and development model of "experience-guided experiment" has been unable to meet the new material research and development needs. The development of a new model of high efficiency and low cost materials development is an urgent need to vigorously promote the development of materials including rare earth steel and support the development of advanced manufacturing and high technology.
Someone has counted an account, if China's output of rare earth steel can reach 35 million tons / year, then the annual consumption of mixed rare earth (with excess lanthanum, cerium-based) 21000 tons. From this perspective, the development of rare earth steel can not only promote the steel industry to upgrade, but also to achieve the comprehensive utilization of rare earth elements, to promote the healthy development of rare earth industry also has a positive effect.
As a new economic growth point in the restructuring and transformation of the country's economy, the rare earth industry has great potential for development. Next, our country should implement the strategy of "rare earth +", no longer rely on the old ways of selling raw materials, make greater efforts in the development of rare earth steel, and promote the technological advantages of rare earth steel into industrial, economic and strategic advantages, The formation of rare earth industry chain and steel industry chain mutual support and benign interaction pattern.
