<p>A mounting block and an improved mounting arrangement for apparatus used in metal melting, refining and processing, particularly those apparatus adapted to steel making in an electric arc furnace, such as burners, lances and the like with supersonic oxygen lancing capability. The mounting block is fluid cooled to survive the hostile environment of the electric arc furnace and is designed to rest on the step between the side wall and hearth of the furnace without any substantial change to the structure of the furnace. The mounting block comprises a plurality of fluid cooling conduits surrounding an aperture which is formed through the block and adapted to mount the apparatus. The mounting arrangement includes utilizing the mounting block to mount an apparatus with supersonic oxidizing gas or lancing capability in an electric arc furnace. The apparatus is mounted by passing it through an aperture in a water cooled side panel aligned with the mounting aperture in the mounting block. Because the mounting block is approximately the width of the step, the discharge opening of the apparatus is moved closer to the surface of the melt and toward the center of the furnace thereby providing increased efficiency. The discharge opening will now also extend past the inner edge of the step so that the oxidizing gas flow pattern does not degrade the hearth material and other furnace equipment mounted nearby.</p> |
