Title: PRACTICE OF WHOLE COURSE NITROGEN CONTROLFOR MOLTEN STEEL OF CSP THIN SLAB CASTING
Abstract: This paper briefly introduces the theory of nitrogen control for molten steel of CSP thin slab casting.The nitrogen content of steel w(N) before and after LF refining furnace treatment were measured under different bottom-blowing conditions. In order to meet the needs of steel quality for decreasing nitrogen, the following measures were taken: an optimal changing-over time of nitrogen and argon was kept at about 10 minutes;the buried arc and atmosphere-controlled operations were adopted in LF furnace;the extended nozzle and protective casting with argon sealing were used between tundish and ladle,etc.
