ABSTRACT:
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 The liquid metal is withdrawn in the presence of an outer elongated upwardly travelling alternating electromagnetic levitation field and a second inner electromagnetic levitation field for maintaining the tubular liquid metal column in a substantially weightless and pressureless contact 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 The resulting solidified tubular metal product is withdrawn from the upper portion of the field, cooled and further processed to result in a desired and product/and has a homogeneous, fully dense, fine grain structure due to continuous eddy current stirring by the levitating electromagnetic fields and a ripply, shiny exterior surface.
