摘 要：<正> 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 PCO,thissteelmgking process was favorable to reduce theamount of [C] and [O] and increase the （P2O5）/[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.
