Abstract:Under the promotion of the 13th five-year plan,the steel rolling technology of China has made rapid progress and remarkable achievements,presenting a large number of high-level achievements in science and technology. Modern technologies,such as big data,Internet,digitization and intellectualization,provide advanced and efficient means for research and development,production,scientific and technological innovation of high quality and performance steel. The steel output has increased from 1.048 billion tons in 2016 to 13.25 billion tons in 2020,with the self-sufficiency rate of high performance steel exceeding 98.5%,which provides the key basic material support for the national economic development and construction. The development and progress of China's steel rolling technology and the representative scientific and technological achievements during the 13th five-year plan period were briefly introduced and analyzed,focusing on the overall production situation of China's steel rolling products and the representative scientific and technological achievements of steel rolling technology. The key technologies and application of representative scientific and technological achievements are briefly introduced from the aspects of rolling process basis and microstructure controlling,greening rolling,digital and intelligent rolling,development of high strength and performance hot rolling products and advanced hot rolling technology,high performance,high strength,high precision cold rolling products and advanced cold rolling technology. Finally,the future development of steel rolling technology is prospected.
