Development of disk connections between billets in columns and energy-efficient graphitizing regulations for electrodes in direct-heating furnaces

The requirements for electric contact joints between workpieces in the core columns of Kastner furnaces are formulated. The choice of a material - graphite foam - for making electric contact gaskets is justified. Rational form and thickness of electric contact pads have been determined, the glue for their fixation between electrode blanks has been selected. A mold for forming electrocontact pads has been developed and prototypes of pads of different shapes, thickness and density have been made in order to check their suitability for forming Kastner furnace core under industrial conditions.
