METHOD OF GRAPHITISATION OF CARBON PRODUCTS AND DEVICE FOR ITS REALISATION Russian patent published in 2013 - IPC C01B31/04 F27D11/04 

FIELD: chemistry.

SUBSTANCE: invention is intended for electrode industry. Carbon products are laid between current leads with formation of electric circuit. Electric connection between current leads and carbon products is realised by means of graphite bridges. Power mechanism for compression of carbon products by technological effort, directed longitudinally with respect to their axes, is interacted with back current leads. Upper and lower graphite bridges are rigidly connected both to each other and to current leads with detachable connection via graphite plates, installed with their bases into slots of upper and lower bridges. Carbon products are heated to temperature of graphitisation by transmitting electric current through them. Device for graphitisation of carbon products contains electric resistance furnace, located in it graphitisation chambers, which include oppositely located current-conducting modules, consisting of graphite bridges with current leads movably installed between them, and a couple of frontal current leads, connected with electric energy source. Device is also provided with guides for oriented laying of modules on them and slots for current leads, made in each module from the side of butt ends of upper and lower bridges.

EFFECT: increased reliability of device operation, increased service term of bridges and inter-repair cycle, simplified preparation of furnace to work.
