Abstract

Abstract This invention relates to a process and apparatus for the production of metal filaments having controlled widths by rolling and quenching from the molten state between the contact faces of two contiguous cooperating rotary elements having contact face widths that are essentially coextensive with the width of the filament to be produced. This technique causes any excess molten alloy to be dispersed laterally rather than to pass vertically between the elements. Optionally, the apparatus may be equipped with shearing means to remove any excess flash.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 107 words
In an apparatus for the production of metal filaments from a molten stream ejected from a source of molten metal wherein the contact faces of contiguous cooperating rotary elements are used as the quenching source, the improvement which comprises orienting the rotary elements so that the molten metal is introduced into the nip thereof, providing contact faces on the rotary elements which allow unconfined lateral dispersion of the excess of said molten stream quenched on said contact faces, said contact faces comprising widths that are in the range of about 0.003 to 0.100 inch and are essentially coextensive with the width of the filament to be produced.
Claim 2
Dependent Claim 107 words
In an apparatus for the production of metal filaments from a molten stream ejected from a source of molten metal wherein the contact faces of contiguous cooperating rotary elements are used as the quenching source, the improvement which comprises orienting the rotary elements so that the molten metal is introduced into the nip thereof, providing contact faces on the rotary elements which allow unconfined lateral dispersion of the excess of said molten stream quenched on said contact faces, said contact faces comprising widths that are in the range of about 0.003 to 0.100 inch and are essentially coextensive with the width of the filament to be produced.
Claim 3
Dependent Claim 31 words
The apparatus of claim 1 wherein a shearing means adjacent to the rotary elements is incorporated into the apparatus contiguous to the rotary elements to remove the laterally dispersed excess flash.
Claim 4
Dependent Claim 21 words
The apparatus of claim 1 wherein the rotary elements are complementarily contoured so as to prOduce a correspondingly shaped metal filament.
Claim 5
Dependent Claim 22 words
The apparatus of claim 1 wherein the contact face of the quenching elements is narrower than the supporting width of the elements.
Claim 6
Dependent Claim 27 words
The apparatus of claim 1 wherein the width of the contact face of the quenching rotary element is in the range of about 0.003 to 0.100 inch.
Claim 7
Independent Claim 115 words
A method of making metal filaments having controlled width in the range of about 0.003 to 0.100 inch from a molten stream which comprises: a. adjusting two contiguous cooperating rotary quenching elements, which have contact faces that essentially coincide with the desired width of the filament, so that the molten stream is received within the nip of said rotary elements; b. passing the molten stream, at a rate in excess to that required to produce said width, between the rotating elements to effect quenching of the stream while allowing said excess of the molten stream to be ejected laterally without confinement from the quenching rotary element; and c. recovering the substantially solidified filament thus formed.
Claim 8
Independent Claim 115 words
A method of making metal filaments having controlled width in the range of about 0.003 to 0.100 inch from a molten stream which comprises: a. adjusting two contiguous cooperating rotary quenching elements, which have contact faces that essentially coincide with the desired width of the filament, so that the molten stream is received within the nip of said rotary elements; b. passing the molten stream, at a rate in excess to that required to produce said width, between the rotating elements to effect quenching of the stream while allowing said excess of the molten stream to be ejected laterally without confinement from the quenching rotary element; and c. recovering the substantially solidified filament thus formed.
