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.
