Abstract：The main reasons of upwarping defect in the production process of hot-rolled strip steel are analyzed and summarized in this article.This paper describes the influence of the immersion depth of the crystallizer nozzle,the structure of the mold nozzle,the casting speed,the billet heating,the surface condition of rough rolling rolls and quality of finish rolling plate on the occurrence of warping.Combined with strip steel production,the production measures for controlling upwarping defect in steelmaking and rolling production processes are described.
