Abstract
Abstract An improved cooling fluid for an apparatus for the manufacture of a wire by projecting a jet of liquid metal or metal alloy through a nozzle into a cooling enclosure containing the cooling fluid is characterized by the fact that the cooling fluid consists of a mixture of a gas and steam, the gas and the steam being compatible with the jet, the gas furthermore being at a temperature below the condensation point of the steam, so as to transform at least a part of the steam into liquid droplets.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
144 words
A cooling fluid for an apparatus for the manufacture of a solid wire by projecting a jet of liquid metal or metal alloy through a nozzle into a cooling enclosure containing the cooling fluid in which the transformation of the liquid jet into solid wire takes place, characterized by the fact that the cooling fluid consists of a mixture of a gas and steam, the gas and the steam being compatible with the jet, the gas furthermore being at a temperature below the condensation point of the steam, so as to transform at least a part of the steam into liquid droplets, said liquid droplets which enter into contact with the jet having diameters which at most equal to 2.5% of the diameter of the wire produced and being selected in suitable diameter by the centrifugation of the cooling fluid in the cooling enclosure.
Claim 2
Dependent Claim
144 words
A cooling fluid for an apparatus for the manufacture of a solid wire by projecting a jet of liquid metal or metal alloy through a nozzle into a cooling enclosure containing the cooling fluid in which the transformation of the liquid jet into solid wire takes place, characterized by the fact that the cooling fluid consists of a mixture of a gas and steam, the gas and the steam being compatible with the jet, the gas furthermore being at a temperature below the condensation point of the steam, so as to transform at least a part of the steam into liquid droplets, said liquid droplets which enter into contact with the jet having diameters which at most equal to 2.5% of the diameter of the wire produced and being selected in suitable diameter by the centrifugation of the cooling fluid in the cooling enclosure.
Claim 3
Dependent Claim
55 words
The cooling fluid according to claim 1, characterized by the fact that the cooling fluid is imparted a movement of rotation in the portion of the cooling enclosure adjacent the nozzle, the wall of the adjacent portion having the shape of a surface of revolution around an axis parallel to the axis of the nozzle.
Claim 4
Dependent Claim
57 words
The cooling fluid according to claim 2, characterized by the fact that the cooling fluid is imparted a movement of rotation by means of a fan arranged near the wall of the adjacent portion for propelling the cooling fluid along an axis located at a distance other than zero from the axis of revolution of the wall.
Claim 5
Dependent Claim
61 words
The cooling fluid according to claim 2, characterized by the fact that the cooling fluid is imparted a movement of rotation by means of at least one steam delivery tube arranged near the wall of the adjacent portion for propelling the cooling fluid along an axis located at a distance other than zero from the axis of revolution of the wall.
Claim 6
Dependent Claim
36 words
The cooling fluid according to claim 3, characterized by the fact that the axis of propulsion of the cooling fluid and the axis of revolution of the wall form an angle which is adjustable in space.
Claim 7
Independent Claim
155 words
An apparatus for the manufacture of a solid wire by projecting a jet of liquid metal or metal alloy through a nozzle into a cooling enclosure containing a cooling fluid in which the transformation of the liquid jet into solid wire takes place, said cooling fluid consisting of a mixture of a gas and steam, the gas and the steam being compatible with the jet, the gas furthermore being at a temperature below the condensation point of the steam, so as to transform at least a part of the steam into liquid droplets, characterized by the fact that the portion of the cooling enclosure adjacent the nozzle has a wall having the shape of a surface of revolution around an axis parallel to the axis of the nozzle and has means for imparting to the cooling fluid a movement of rotation around said axis of revolution, the gas feed being distinct from the steam feed.
Claim 8
Independent Claim
155 words
An apparatus for the manufacture of a solid wire by projecting a jet of liquid metal or metal alloy through a nozzle into a cooling enclosure containing a cooling fluid in which the transformation of the liquid jet into solid wire takes place, said cooling fluid consisting of a mixture of a gas and steam, the gas and the steam being compatible with the jet, the gas furthermore being at a temperature below the condensation point of the steam, so as to transform at least a part of the steam into liquid droplets, characterized by the fact that the portion of the cooling enclosure adjacent the nozzle has a wall having the shape of a surface of revolution around an axis parallel to the axis of the nozzle and has means for imparting to the cooling fluid a movement of rotation around said axis of revolution, the gas feed being distinct from the steam feed.
Claim 9
Dependent Claim
48 words
The apparatus according to claim 6, characterized by the fact that said means consists of a fan arranged near the wall of the adjacent portion for propelling the cooling fluid along an axis located at a distance other than zero from the axis of revolution of the wall.
Claim 10
Dependent Claim
52 words
The apparatus according to claim 6, characterized by the fact that said means consists of at least one steam delivery tube arranged near the wall of the adjacent portion for propelling the cooling fluid along an axis located at a distance other than zero from the axis of revolution of the wall.
Claim 11
Dependent Claim
35 words
The apparatus according to claim 7, characterized by the fact that the axis of propulsion of the cooling fluid and the axis of revolution of the wall form an angle which is adjustable in space.
