Abstract

In No.2 Steelmaking Plant of WISCO,80 t ladle has been lined with single permeable bricks.In order to improve the efficiency of argon bubbling,full bottom argon bubbling operation has been realized in the plant after a long period of tackling key problems.To meet the demand of multi-grades steel production as the prerequisite,the target-hit ratio of converter smelting reached over 99.95 % and the top argon bubbling device has been dismantled.
