Application and research of rare earth in seamless steel pipe
Application of Rare Earth in Seamless Steel Pipes:
REEs are important technical elements in many steel products and can significantly change their convenience and bright performance. As the addition of a very small amount of REEs can significantly improve their properties, they have been widely used in the manufacturing of seamless steel pipes.
Rare earth elements like lanthanum, Ce, Nd, Sm and Y can help to refine the grain size and can refine the tube blank in the steel industry. With their small addition, the grain size of steel can be refined, which will result in an increase of strength properties, toughness and ductility.
REEs have also been widely used to improve homogenization, reduce non-metallic inclusions, improve mechanical properties and increase fatigue strength of seamless steel pipe. Apart from these, REEs facilitate the production of seamless steel pipe with higher strength, fatigue strength and superior mechanical properties.
RECs are also able to improve the surface quality of seamless steel pipes, making them more suitable for complicated machining, especially in cases when high level of surface accuracy is required.
Research of Rare Earth in Seamless Steel Pipe
Recently, numerous innovative methods and technologies have been developed to further improve the efficiency in steel production and enhance the properties of seamless steel pipe.
One of the most studied subjects is the use of REEs in steel production. Studies have proven that by adding optimal amounts of REEs in steel production, the strength, flexibility and fatigue resistance can be increased significantly. This was achieved by using several different techniques, including pressure-assisted solidification, double-strand continuous casting, hot metal rolling and cold rolling.
Studies have also found that the addition of REEs can have positive effects on the corrosion resistance and weldability properties of seamless steel pipes. Research have shown that REEs can have positive effects on the microstructure of seamless steel pipes, leading to a decrease in the number of non-metallic inclusions. Additionally, studies have also proved that REEs improve the fatigue performance of seamless steel pipes significantly.
Rare earth elements have become increasingly more important in the seamless steel pipe production over the years and this trend is expected to continue in the future. REEs play a significant role in improving the mechanical properties of seamless steel pipes and making them suitable for a wide range of demanding applications. Studies have helped to understand the effects of REEs on the grain refinement of seamless steel pipes, increasing the fatigue properties, weldability and corrosion resistance.
In conclusion, the use of REEs in the production of seamless steel pipes has become inevitable due to their efficiency compared to traditional techniques and their ability to provide superior mechanical properties for challenging applications.
