METHOD AND ARTICLE FOR INTRODUCING DENITROGENIZING FLUX INTO MOLTEN METAL

摘要

Method and article for introducing a denitrogenizing flux material (26) into molten metal (22) including the steps of providing a wire-like vector (14) that has an inner core of flux material (26) and an outer layer (24) that is used to contain the inner core of flux material (26) and introducing the wire-like vector (14) into the molten metal (22). Also a method of introducing a powdered denitrogenizing flux (40) into molten metal (32) using a lance (42).
