Abstract

A burner and/or injector panel apparatus includes a flange rotatable within a cylindrical aperture in a horizontal plate and securely retainable between one or more retaining clips and the plate. Extending downward from the flange is a main body with a cylindrical chamber. A burner, burner/injector, or injector is contained within the cylindrical chamber. The main body has a helical cooling circuit extending around the cylindrical chamber and burner and/or injector. The burner and/or injector panel apparatus may be installed through a furnace wall, especially an electric arc furnace, more particularly, a balcony panel of a sump area of an electric arc furnace. The burner and/or injector panel apparatus may be tilted from horizontal or rotated around its vertical axis in order to better target a target area of a molten bath of metal with a flame, jet of oxygen, or stream of carbon particles.

First claim

What is claimed is:

1. A metal melting furnace panel apparatus for a burner and/or for an injector, said panel apparatus comprising:
a horizontal plate having a lower surface, an upper surface, and a vertically oriented cylindrical aperture extending through said upper and lower surfaces;
a horizontally extending flange having a uniform height along its periphery and having a vertically extending axis, a width or diameter of said flange being greater than a diameter of said cylindrical aperture;
a main body integrally formed with said flange and extending downwardly therefrom along a main body axis at an angle to a vertical axis of said flange, said main body having a centrally disposed cylindrical chamber extending upper and lower ends thereof, said integrally formed flange and main body being operatively associated with said plate such that:
in operation, said flange rests atop said plate while said main body projects downwardly though said cylindrical aperture,
when said flange is rotated atop said plate around the flange's vertically extending axis, because said flange is integrally formed with said main body, said main body is rotated within said cylindrical aperture,
said plate is adapted and configured to retain said plate in fixed position; and

a burner and/or injector inserted in said main body cylindrical chamber adapted and configured to inject therefrom at least one of a flame, a jet of oxygen, and a stream of carbon particles.

2. The metal melting furnace panel apparatus of claim 1 , further comprising:
one or more fasteners; and
one or more retaining clips corresponding to said one or more fasteners, wherein said plate further comprises one or more studs corresponding to said one or more retaining clips upwardly projecting from an upper surface of said plate, said clips being adapted and configured to be fastened to said studs with said fasteners so as to fixedly secure said flange between said plate and said one or more clips.

3. The metal melting furnace panel apparatus of claim 1 , wherein said main body has a cylindrical configuration coaxial with said cylindrical chamber.

4. The metal melting furnace panel apparatus of claim 1 , wherein said flange has a cylindrical configuration and said flange diameter is greater than a diameter of said cylindrical aperture.

5. The metal melting furnace panel apparatus of claim 1 , wherein said burner and/or injector comprises a burner.

6. The metal melting furnace panel apparatus of claim 1 , wherein said burner and/or injector comprises an oxygen injector.

7. The metal melting furnace panel apparatus of claim 1 , wherein said burner and/or injector comprises a burner and an oxygen injector.

8. The metal melting furnace panel apparatus of claim 1 , wherein said burner and/or injector comprises a carbon particle injector.

9. The metal melting furnace panel apparatus of claim 1 , wherein said burner and/or injector comprises a burner and a carbon particle injector.

10. The metal melting furnace panel apparatus of claim 1 , wherein said burner and/or injector comprises a burner, an oxygen injector, and a carbon particle injector.

11. A metal melting furnace panel apparatus for a burner and/or for an injector, said panel apparatus comprising:
a horizontal plate having a lower surface, an upper surface, and a vertically oriented cylindrical aperture extending through said upper and lower surfaces;
a horizontally extending flange having a uniform height along its periphery and having a vertically extending axis, a width or diameter of said flange being greater than a diameter of said cylindrical aperture;
a main body integrally formed with said flange and extending downwardly therefrom along a main body axis at an angle to a vertical axis of said flange, said main body having a centrally disposed cylindrical chamber extending upper and lower ends thereof, said integrally formed flange and main body being operatively associated with said plate such that:
in operation, said flange rests atop said plate while said main body projects downwardly though said cylindrical aperture,
when said flange is rotated atop said plate around the flange's vertically extending axis, because said flange is integrally formed with said main body, said main body is rotated within said cylindrical aperture,
said plate is adapted and configured to retain said plate in fixed position; and

a burner and/or injector inserted in said main body cylindrical chamber adapted and configured to inject therefrom at least one of a flame, a jet of oxygen, and a stream of carbon particles, wherein said integrally formed flange and main body include a cooling circuit having a helically shaped portion in said main body extending around said cylindrical chamber.

12. An electric arc furnace installation, comprising:
a furnace having a hearth adapted and configured to contain a bath of molten metal;
a sump region with a tap hole;
sidewalls extending upwardly and around said hearth and sump region;
a balcony panel extending horizontally over said sump region and having a cylindrical opening; and
the metal melting furnace panel apparatus of claim 1 , said plate being secured to an exterior surface of said balcony panel and said cylindrical aperture is aligned with said balcony panel cylindrical opening, said main body extending downwardly through said balcony panel cylindrical opening.
