Abstract (en)
The metal tubes e.g. copper alloys are obtained by continuous or semi-continuous gravity casting of a tube blank and then the cold drawing of this blank. Also claimed is an installation for the manufacture of the tubes, comprising (a) a set of equipment for casting the tube blank consisting of a reservoir (12) for liquid metal with an opening in its bottom in which a mandrel (14) is engaged, a mould (13) in which the metal is solidified, an electromagnetic stirring annulus (15), a cooling annulus (16) and an extraction system (18) and (b) a cold drawing and heat treatment assembly made up of a drawing machine, a drawing bench and a reheating furnace.
