The use of technology with the intermediate flushing of slag at blowing out and
complete its abandonment after the scarification of fettling can be effective only at correct
determination of oxygen blowing out moment stopping, that possibly at presence of adequate
model of technological process. The presented approach allows to reduce an expense
of lime on 10.7 kg/t, dolomite on 1.1 kg/t, oxygen on 2.0 m3/t, common quantity of
slag on 15.0 kg/t, eventual content of phosphorus in 1.5-2.0 times as compared to base
technology.
Keywords: oxygen converter, phosphorus, oxygen blowing-off, smelting technology,
