Abstract
Abstract A metallurgical vessel, particularly for use as a converter, includes a receptacle tiltably mounted on supporting journals fitted into bushings. Media for treating the contents of the receptacle and/or for cooling the outside walls of the receptacle is fed to the receptacle by feed and delivery pipes connected at one end to a distributor and at the other end to at least one of the bushings. A plurality of bores axially extending through the bushing and connected to the delivery pipes is provided as means for communicating the media to the receptacle. The bores extend parallel to the axis of the supporting journal and are disposed in a circumferential arrangement around and coaxial with the axis of the supporting journals.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
177 words
A metallurgical vessel for use as a converter comprising a receptacle, means for tiltably supporting said receptacle including a pair of journals forming an axis about which said receptacle is tiltable a plurality of bores extending in a direction parallel to the axis of said supporting journals and disposed in an annular arrangement coaxial with the axis of said supporting journals and providing passages for feeding media therethrough to the interior of said container for treating the contents thereof and/or for feeding media to said receptacle for cooling said receptacle, each said bore having an inlet end for receiving the media and an outlet end for supplying the media to said receptacle, a distributor, and delivery pipes each connected at one end thereof to said distributor for receiving the media therefrom and at the other end thereof to said inlet end of one of said bores wherein the improvement comprises a bushing fitted on one of said supporting journals, said plurality of bores located in and extending axially through said bushing radially outwardly from said supporting journal.
Claim 2
Dependent Claim
177 words
A metallurgical vessel for use as a converter comprising a receptacle, means for tiltably supporting said receptacle including a pair of journals forming an axis about which said receptacle is tiltable a plurality of bores extending in a direction parallel to the axis of said supporting journals and disposed in an annular arrangement coaxial with the axis of said supporting journals and providing passages for feeding media therethrough to the interior of said container for treating the contents thereof and/or for feeding media to said receptacle for cooling said receptacle, each said bore having an inlet end for receiving the media and an outlet end for supplying the media to said receptacle, a distributor, and delivery pipes each connected at one end thereof to said distributor for receiving the media therefrom and at the other end thereof to said inlet end of one of said bores wherein the improvement comprises a bushing fitted on one of said supporting journals, said plurality of bores located in and extending axially through said bushing radially outwardly from said supporting journal.
Claim 3
Dependent Claim
57 words
The metallurgical vessel according to claim 1 further comprising a plurality of connecting pipes each connected at one end thereof to the outlet end of one of said plurality of bores on the end of said bushing adjacent said receptacle and connected at the other end thereof to points of use for said media on said receptacle.
Claim 4
Dependent Claim
27 words
The metallurgical vessel according to claim 2 wherein said delivery pipes are connected to the inlet ends of said bores in the axial direction of said bushing.
Claim 5
Dependent Claim
27 words
The metallurgical vessel according to claim 2 wherein said delivery pipes are connected to the inlet ends of said bores in the radial direction of said bushing.
Claim 6
Dependent Claim
27 words
The metallurgical vessel according to claim 2 wherein said connecting pipes are connected to the outlet ends of said bores in the axial direction of said bushing.
Claim 7
Dependent Claim
23 words
The metallurgical vessel according to claim 2 wherein said connecting pipes are connected to said bores in the radial direction of said bushing.
Claim 8
Dependent Claim
46 words
The metallurgical vessel according to claim 2 further comprising a supporting ring for supporting said receptacle therein, and wherein said delivery pipes and said connecting pipes are connected to said supporting journal on the outside of said supporting ring to permit tilting movement of said vessel.
Claim 9
Dependent Claim
36 words
The metallurgical vessel according to claim 2 further comprising a plurality of spare bores extending through said bushing and the inlet and outlet ends of said spare bores being closed and being available for subsequent use.
