| 摘要 |
<p>The present invention describes apparatus (10) for pre-heating a carbon body (12,12') prior to pitch impregnation, utilizing electrical current flow through the carbon body (12,12') along their longitudinal axes. The apparatus comprises a framework (34,30,32,40,34'32'40') on which first and second electrical contact means (60,70,60',70') are movably supported. In use the carbon body is supported on the framework (34,30,32,40,30',32'40') by stationary roller assemblies (46) and the electrical contact means (60,70,60',70') are pressed against opposite ends of the carbon body (12,12') by respective adjustable pressing assemblies (64,74) <IMAGE></p> |
