| Abstract: | The site tracking and analysis were conducted because of the surface upwarping of heavy plates manufactured by Baosteel.The results showed that the defects mainly related to the quality of continuously cast slab.Some measures were taken to ensure the quality of continuously cast slab.The measures include adjustment of the argon flow rate at the cast nozzle,control of the depth-to-width ratio for cleaning,optimization of the clean-up mode of slab,etc.Now the defects of surface upwarping of heavy plates have ... |
