About 70% of steel is nowadays produced via different variants of basic oxygen converters. The converter process was developed in the middle of the nineteenth century using bottom-blown air for oxidation.

    In the case of conditions B, C, and E, it is thought that the increase in the particle diameter of the slag during flux addition is slow, and aggregation proceeds after the end of flux addition. Since the flux addition time is 10 min in condition C and 3 min in condition E, the treatment time after flux addition is longer in condition E.
