2、Feng Shichao(TechnologyCenter ofAngang SteelCo. , Ltd. )Abstractnull The current technicalsituation of new duplex steelmaking technology for converter isdescribed, each dephosphorization process developed by enterprises at homeand abroad such as JFEaSum itomoM etalsaN ippon SteelaKobeSteel, Baosteel
3、, etc. and theirproduction are introduced. Du-plex steelmaking technology is simpler than the conventionalone, the free room in converter is larger,the reaction dynam ics condition is better, the production cost is cheaper, and phosphorus content inliquid ironmaybegenerally reduced to0. 010%.
