Processes are considered for conversion of high-phosphorus cast iron during steel smelting in 300-ton oxygen converters of AO Arselormittal Temirtau beneath magnesia slags of sensible composition. Technology is developed and assimilated, including application towards the end of blowing with oxygen of saturated magnesia slag (8 − 11% MgO) with basicity 3.0 − 3.4 and formation of a wear-resistant skull coating (with resistance of 1–2 melts) on the lining during slag blowing with high-pressure nitrogen with additions of magnesia alumina flux (MAF). Use of MAF flux provides an increase in slag MgO content (up to 9 − 10%) with maintenance of required metal dephosphorizing within the limits 97.1 − 98.1% with a phosphorus content in metal on average of 0.013 − 0.017%.
