A guide tube structure for flux concentration is provided. The discharge guide tube comprises a central orifice that extends from a source of metal to an outlet in the discharge guide tube for directing a stream of melt therethrough; a structure that generates an electromagnetic field in the discharge guide tube; and an interior discharge guide tube flux concentration configuration that is capable of concentrating at least one of heat, electromagnetic field, and electromagnetic flux onto the stream of melt that flows through the central orifice. The electromagnetic field is applied at a substantially constant level.

[ What is claimed is:] [1.]1. A discharge guide tube for a metal refining or melting apparatus, the discharge guide tube having a substantially right cylindrical outer configuration and comprising:a base plate forming a hearth of the melting apparatus and an extension through which a central orifice originating in the base plate and extending from a source of metal through the extension to an outlet for directing a stream of melt therethrough;a structure that generates an electromagnetic field in the discharge guide tube; andan interior discharge guide tube flux concentration configuration comprising an angled and stepped profile having a reduced diameter at its central portion that is capable of concentrating electromagnetic flux resulting from the generated electromagnetic field onto the stream of melt that flows through the central orifice, resulting in heating the stream, and the electromagnetic field being applied at a substantially constant level.
