Method of and apparatus for continuously forming a flexible elongate metallic member

Abstract From the Canadian patent

A flexible elongate metal member e.g. a rod or wire, is continu-, ously formed by causing molten metal contained in an upstanding tube to be ejected out of the open upper end of the tube whilst at the same time, establishing about said upper end an alternating electromagnetic field which sets up forces such as to cause the ejected metal to be compressed inwardly to form a column of molten metal which protrudes from the tube. The column of molten metal is cooled to such an extent that at least an upper end part of the column is in a substantially solid state and whilst molten metal is, fed into a lower part of the tube the substantially solidified part of the column of metal is withdrawn …
