ABSTRACT:
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.
