Abstract
A furnace for pre-heating carbon bodies prior to pitch impregnation utilizing electrical current flow through the body along its longitudinal axis. The furnace is an apparatus which includes a structural steel framework with roller assemblies to support a carbon body. Electrical contacts and pressing assemblies are provided for establishing pressing forces on the carbon body and the apparatus is configured so that a carbon body can be received on the roller assemblies and contacted by the electrical contact means by adjustment of the pressing assemblies.
