发明名称 COMPOSITIONS AND TWO-STAGE METHODS FOR THE DEOXIDATION OF MOLTEN STEEL
摘要 Deoxidizing compositions and two-stage methods for deoxidizing molten steel produce purer steel products, at lower cost, than traditional aluminum and silicon-based deoxidation technologies. A first deoxidizing composition is free from elemental aluminum and reduces oxygen content primarily by the conversion of carbon to carbon monoxide, along with the conversion of silicon to silica. A subsequently-added second deoxidizing composition lowers the oxygen content to a highly desirable level, with the production of substantially less alumina impurities than the prior art technologies.
