Abstract

PURPOSE: To effectively promote dephosphorization reaction, etc. of hot iron by setting the flow rate of oxygen from a nozzle near the hot iron inflow side of a trough type furnace or the like higher than that from a nozzle at the outlet side.
CONSTITUTION: In a trough type continuous predephosphorization furnace or the like, the flow rate of oxygen from nozzles is gradually increased from the molten metal inflow side to the molten metal outflow side. That is, much oxygen is blown at a part where decarburization occurs slightly, and a restricted vol. of oxygen is blown at a part where CO is formed actively. Thus, one or more places blown with oxygen at a controlled flow rate are set in the furnace to equalize the sum of the flow rate of oxygen and that of CO in the vicinity of each of the nozzles. By accomplishing slag-metal reaction of this method in a high carbon noze of above 2% carbon concn. with vigorous agitation, continuous steel making is promoted efficiently.
