Abstract: A process and device for producing a wire (12) made of amorphous metal alloy having an iron base by producing a jet (7) of molten alloy (4) through the orifice (60) of a die (6), and introducing this jet (7) into a cooling liquid (9) urged by centrifugal force against the inner wall of a rotary drum. The crucible (2) containing the alloy (4) and the die (6) are made using different materials and are joined by a joint (25) the material of which differs from those of the crucible (2) and of the die (6). Furthermore, means (3) are employed for heating the alloy (4) both in the crucible (2) and in the die (6) and an inert or reducing gas is delivered directly in contact with the jet (7) as it leaves the die (6). Wire (12) obtained with this process or this device, this wire being employed, for example, for reinforcing pneumatic tires.

Abstract: Method and apparatus (20) for obtaining a wire (12) of amorphous metallic loy, characterized by the fact that a jet (7) of molten amorphizable alloy (4) is contacted with a gas (55) capable of reacting chemically with at least one of the components of the alloy (4) before the jet (7) reaches a cooling liquid (9), so as to form a layer around the jet (7) which is capable of stabilizing it. A distance traversed by the jet (7) between the nozzle and the cooling liquid is greater than 1 cm.

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.
