Zusammenfassung:CONTINUOUS METAL TUBE CASTING METHOD, APPARATUS AND PRODUCT Dense, homogeneous tubular metal products such as pipe is cast in long lengths continuously by introducing liquid metal into the lower portion of an annular-shaped casting vessel. The liquid metal is withdrawn in the presence of at least one elongated upwardly travelling alternating electromagnetic levitation field and a second inner electromagnetic containment field for maintaining the tubular liquid metal column in a substantially weightless and pressureless condition while solidifying. The resulting solidified tubular metal product is withdrawn from the upper portion of the field, cooled and further processed to result in a desired end product.
