Abstract:The paper briefly describes the history of stainless steel development in Taiyuan Iron and Steel (Group) Co. Ltd. (TISCO) China, describes in detail the major progresses of stainless steel development in TISCO since the ninth Five-Year Plan, including the revamping project of 500000 t stainless steel production line and the expansion project of 400000t cold rolled stainless steel sheets. The achievements in the state key task in Ninth Five-Year Plan “Technological Development of High Quality Stainless Steel Flat Products”, tackling the problems for quality improvement, developing of products, tapping the potentials according to standards, which has made the stainless steel in TISCO develop in a great leap. The paper also introduces synoptically the main contents and characteristics of processes and technologies of the new 1.5×106 t stainless steel project that is in the progress of approval. The paper, combining with the actuall practics of TISCO, also analyses and compares the advanced processes and technologies to be used in the new project of TISCO with the most advanced international processes and technologies for the stainless steel production line including the stainless steelmaking, hot rolling and cold rolling.
