ABSTRACT:
In the refining of steel by an oxygen topblown converter, the temperature and carbon content of molten steel are simultaneously measured by a sensor at a predetermined time before the end point, whereby in accordance with the difference between a calculated carbon content at the endpoint obtained by processing the measured values and a target carbon content at the end-point, the oxygen quantity to be blown in at the end-point and the coolant requirement or the pattern of soft-blow are computed to simultaneously control the temperature and carbon content of the molten steel at the end-point.
