  • Particulate slagging composition for the extended optimum continuous casting of steel
    Patent number: 4235632
    Abstract: A particulate slagging composition for the extended optimum continuous casting of a steel which tends to evolve alumina into the molten protective layer of said composition maintained on the top of a pool of molten steel. Such particulate slagging composition is characterized by a R' ratio (the sum of the theoretical net oxide analysis values of CaO+MgO+BaO+SrO+MnO+FeO+F+B.sub.2 O.sub.3 to the theoretical net oxide analysis value of SiO.sub.2) preselected for obtaining Opertional ADK values not substantially in excess of about 750 seconds after substantial absorption of alumina from the steel.
