Effect of Additives on Desulfurization Capability of CAS-OB Refining Ladle Slag
, 2011 To avoid slag sticking onto the ladle snorkel during the CAS-OB refining and alloying process, CaO-B2O3 and CaO-CaF2 were respectively employed as modifiers added into the ladle slag. The desulfurization capability of modified slag was investigated.

Refining Method for Refining Cast Iron by the Electrolysis of Slag
Refining Method for Refining Cast Iron by the Electrolysis of Slagapplication/pdf Original researches on the refining method of cast iron by the electrolysis of slag will be described in this paper. Cast iron is not so easily reduced as steel that strong deoxidizing reagents, such as alkali, alkali earth metals and Mg, are necessary to reduce cast iron melts satisfactorily.
