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.
Claims3
Apparatus for pre-heating a cylindrically shaped amorphous carbon body comprising:
- a) a framework formed of structural steel members including
- i) a first vertical steel member arranged opposite to and spaced from a second vertical steel member
- ii) a horizontal steel member spanning the first and second vertical steel members and affixed thereto to provide a rigid structure;
- b) a first stationary roller assembly extending horizontally in-line between the first and second vertical steel members adapted to support an amorphous cylindrically shaped carbon body extending between said first and second steel members and to permit said amorphous carbon body to roll back-and-forth on said roller assembly between said first and second vertical steel members;
- c) a first electrical contact means pivotally supported by and depending downward from said horizontal member adjacent said first vertical support member;
- d) a second electrical contact means rollably supported by and depending downward from said horizontal member adjacent said second vertical support;
- e) a first adjustable pressing assembly fixedly mounted on said first vertical support member for applying a pressing force on said first electrical contact means;
- f) a second adjustable pressing assembly fixedly mounted on said second vertical support member for applying a pressing force on said second electrical contact means;
- said apparatus being configured so that a shaped carbon body can be received on said roller assembly between said first and second electrical contact means and be contacted by said first and second contact means through adjustment of the first and second pressing assemblies.
