In a process and installation for the manufacture of a metal wire from a jet of molten metal, the jet of metal which is in the course of solidification is supported by cooling fluid displaced by two cylinders rotating in opposite directions with a tangential velocity such that the wire is supported in stable equilibrium in the plane of vertical symmetry of the two cylinders above the level defined by the plane perpendicular to the plane of symmetry and passing through the axes of rotation of the two cylinders, the space between the two cylinders being between about 0.15% and 3% of their common radius and their peripheral speed being between about 4 and 120 m/sec.

A process for manufacturing a metal or metallic alloy wire by projecting a jet of molten metal or metallic alloy through a die into a cooling enclosure containing a cooling fluid in which the jet solidifies into a wire along an axis of stability, the cooling fluid being imparted, at least until the solidification of the jet, a movement which is directed perpendicularly towards the jet, characterized by the fact that the axis of the die forms an angle of between 45°and 90°with the descendant vertical and is contained within the same vertical plane as the axis of stability of the wire, and by the fact that in a plane cross section perpendicular to the axis of stability of the wire the velocity of the cooling fluid is distributed symmetrically with respect to the vertical plane so as to reach a minimum in the vertical plane and to have a component parallel to the minimum velocity which increases on both sides of the vertical plane, said cooling fluid velocity also being distributed in such a manner that said minimum velocity at the level of the axis of stability of the wire has a value sufficient to support the wire and impart to it a practically linear trajectory along its axis of stability, said minimum velocity upstream of the axis of stability having a higher value and downstream of the axis of stability a lower value than said wire-supporting value at the level of the axis of stability of the wire.
