Abstract

Abstract

In present Study, two emperical formulas have been obtained for the activity of oxygen, a[o], at the latter period of the blowing course in the 120T BOF Converter in Panzhihua steel Company.
The emperical formula corresponding to the lower carbon content (C ≤ 0.3%), may be used for fast[%C]-determination in which a[o] is o btained by using an oxygen probe.The accaracy of[%C] obtained may reach 0.01% when[%C] is less than 0.10%, For the extention of the application of the formula to a range of C ≤ 0.20%, more experimental work are needed.
The present study shows that Smart decarbonization model is applica ble for the BOF system.A computer control plan for the blowing termin al is proposed based on the decarbonization model and the a[o]-[%C] relation diagrams.
