A furnace apparatus and method for the lengthwise graphitization (LWG) of carbon bodies are provided which utilize U-shaped metal furnace sections mounted on stationary rib supports to contain carbon electrode bodies and surrounding thermally insulating pack material. Vertical flues are provided between parallel rows of U-shaped metal furnace sections to accelerate cooling of graphitized electrode bodies and in a further embodiment water droplets are additionally sprayed on the metal furnace sections.

Apparatus for lengthwise graphitization (LWG) of carbon electrode bodies

Spray cooled side-wall assembly for an electric arc furnace which includes individual spray cooled segments joined together to form a furnace side-wall. One or more of the segments can be arch-shaped and surround a spray cooled sub-assembly to address conditions of high thermal stress.

Modular spray cooled side-wall for electric arc furnaces

Hood assembly for pneumatic process metallurgical vessel, such as BOF, which includes removeable spray cooled sub-assemblies at predetermined locations in the hood assembly.
