Abstract

Abstract There is disclosed herein an annular quench ring surrounding a coaxial, axially relatively moving pipe for spraying a coneshaped pattern of quenching fluid inwardly thereagainst. A sleeve, also coaxial with the pipe, is disposed adjacent to the exit end of the quench ring in the direction of the apex of the cone-shaped spray, the sleeve being spaced radially outwardly of the pipe whereby a substantial portion of the fluid richochets between the load and the inner surface of the sleeve throughout the length of the sleeve to increase the quenching effect.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 120 words
A quenching device for quenching an elongated, relatively moving workpiece comprising an annular quench ring adapted to surround and be spaced radially from the workpiece and direct a high velocity spray of quenching fluid against the workpiece in a conical pattern directed axially outwardly of the exit end of said quench ring; a sleeve member coaxially surrounding and spaced radially from the workpiece at a position spaced axially beyond the exit end of said quench ring whereby a substantial portion of the quenching fluid is deflected from the workpiece and, alternately, impinges on the inner surface of said sleeve and is again deflected from the workpiece throughout substantially the length of said sleeve, to increase the quenching of the workpiece.
Claim 2
Dependent Claim 120 words
A quenching device for quenching an elongated, relatively moving workpiece comprising an annular quench ring adapted to surround and be spaced radially from the workpiece and direct a high velocity spray of quenching fluid against the workpiece in a conical pattern directed axially outwardly of the exit end of said quench ring; a sleeve member coaxially surrounding and spaced radially from the workpiece at a position spaced axially beyond the exit end of said quench ring whereby a substantial portion of the quenching fluid is deflected from the workpiece and, alternately, impinges on the inner surface of said sleeve and is again deflected from the workpiece throughout substantially the length of said sleeve, to increase the quenching of the workpiece.
Claim 3
Dependent Claim 24 words
In a quenching device as set forth in claim 1: means for moving the elongated workpiece through said quench ring for continuous quenching thereof.
Claim 4
Dependent Claim 49 words
In a quenching device as set forth in claim 1: support means mounting said quench ring and said sleeve together as a unit; and means for moving said support means in a path whereby said quench ring and said sleeve travel coaxially along the workpiece for continuous quenching thereof.
