FIELD: graphite coating of carbon members. SUBSTANCE: method involves using set of stationary spaced dielectric fire-proof ribbed resting members which are located on dielectric stationary platform. Every resting member has pair of adjacent U-shaped holes which are positioned side by side, have open top and are spaced from main platform. They are also spaced from one another by means of piece of fire- proof ribbed member strut which is designed as whole. Multiple resting members are located in parallel, so that U-shaped holes match. In addition furnace has multiple insulated U-shaped solid metal sections with open top which external, internal and bottom surfaces are spaced from main platform which is located between adjacent resting members. Ends of metal sections are located in U- shaped holes of resting members. Adjacent metal sections are spaced by vertical air duct which is formed by pieces of resting members, piece of main platform and side surfaces of metal sections. Vertical air duct is open from top and bottom and increased speed shaped as Venturi tube, which bottom hole provides forced air cooling of metal sections of furnace.

SYSTEM FOR GRAFITAR CARBON BODIES

Method and apparatus for graphitizing carbon bodies

Post-coking and graphitizing carbon bodies impregnated with pitch comprises forming strand from carbon bodies, and surrounding with thermal insulating layer Post-coking and graphitizing carbon bodies impregnated with pitch comprises forming a strand from the carbon bodies, and surrounding with a thermal insulating layer. Before heating the carbon bodies, the oxygen content in the furnace is reduced to less than 4 vol.% so that an electrical current can be passed through the strand. The gas pressure is regulated so that it deviates by +10 to -40 Pa from the external air pressure. Gases and/or vapors produced from the carbon bodies and/or from the insulating layer are removed from the furnace using a suction device. An Independent claim is also included for a furnace sink for carrying out the process.
