| 摘 要： | The experiment was carried out in a combinedblowing converter.The natural gas was supplied asthe cooling medium for the bottom lance.The blow-ing practice of medium P hot metal(0.30-0.85% [P]) indicated that with better stirringat the bottom of the converter and lower P_(CO),thissteelmgking process was favorable to reduce theamount of [C] and [O] and increase the (P_2O_5)/[P].The maximum rate of dephospborization might behigh up to 0.0a5%/min and the P content in steelcould be reduced to lower than 0.03% by singleslag-forming operation.

| Abstract: | The experiment was carried out in a combined blowing converter.The natural gas was supplied as the cooling medium for the bottom lance.The blow- ing practice of medium P hot metal (0.30-0.85% [P]) indicated that with better stirring at the bottom of the converter and lower P_(CO),this steelmgking process was favorable to reduce the amount of [C] and [O] and increase the (P_2O_5)/[P]. The maximum rate of dephospborization might be high up to 0.0a5%/min and the P content in steel could be reduced to lower than 0.03% by single slag-forming operation. |
