Abstract (en)
The invention provides a filled tubular article (38) for controlled dissolution in a molten metal for making boron treated steel, comprising: an elongate conduit of ferrous material (56) an elongate, non-particulate member located within the conduit, the member being primarily of aluminum material (58) and a preselected particulate master composition (60) including particles being made of a material containing a preselected amount of the chemical element boron. The invention also provides a method of casting a boron treated steel article by introducing molten steel into a mold (20), the improvement comprising: the introduction below the surface of the molten steel (13) in the mold of preselected percentages by height of aluminum in the form of a non-particulate elongate member and boron in the form of particles of a material containing the chemical element boron, said elongate member and particles being within an outer conduit of ferrous material of a filled tubular article (38)
