The refining control model for stainless steel was developed. At the time of developing this model, the refining index that was concerned with distributing oxygen to C and Cr was derived. The following points were clarified: 1) The refining control model that was composed of the mass balance and the heat balance in the converter and made it possible to estimate the composition of molten steel, the amount and composition of slag, and temperature of molten steel was developed. 2) The refining index (DOS) in which the bulk region as a reaction site in addition to the fire spot regions of top and bottom blowing was taken into consideration, was derived. 3) This model was applied to the actual YAWATA 145t LD-OB converter and it became possible to estimate [%C], [%Cr], temperature of molten steel, and the amount and the composition of slag accurately.
