Abstract
In order to cool the jet coming from a crucible and then the wire as it starts solidifying, there is used a gaseous cooling fluid mixture having a base of gaseous hydrogen and at least one other component which is a compound of hydrogen capable of an endothermic chemical reaction in contact with the jet (wire) and of a chemical composition such that the product or products of this reaction have a high molecular content (mol %) of free hydrogen.
Claims8
A process for cooling a wire of metal or metal alloy produced in an installation comprising essentially a crucible containing the molten metal or metal alloy, a die arranged in a wall of the crucible, an enclosure containing a pressurizing fluid acting on the metal or metal alloy in the crucible and a cooling enclosure following the die and containing a gaseous cooling fluid mixture having a base of gaseous hydrogen and at least one other component, the wire being obtained by projecting a jet of the metal or metal alloy through the die into the gaseous cooling fluid mixture contained in the cooling enclosure, characterized by the use of a gaseous cooling fluid mixture in which said other component is a compound of hydrogen capable of an endothermic chemical reaction in contact with the jet (wire) and of a chemical composition such that the product or products of said reaction have a high molecular content (mol %) of free hydrogen.
