METHOD OF PACKING LARGE-SIZE ISOSTATIC MOULDING FINE-GRAIN GRAPHITE WORKPIECES DURING GRAPHITATION Russian patent published in 2015 - IPC C01B31/04 

FIELD: chemistry.

SUBSTANCE: method of packing fired carbonaceous large-size isostatic moulding fine-grain graphite workpieces during graphitation includes arrangement thereof vertically and horizontally across the core in columns, separated from each other by layers of core filling with thickness of about 0.2 times the diameter of the workpiece. The lateral sides of each workpiece are tightly attached to flat heat-transfer panels made of highly heat-conductive and high-temperature structural graphite. The width of the panel is equal to the diameter or thickness, in case of a workpiece with a rectangular cross-section, and the length is respectively equal to the length of the workpiece, the thickness is not less than 0.15 times of its diameter or thickness, in the case of a workpiece with a rectangular cross-section. The heat-transfer panels can be composite in the direction of their length.

EFFECT: reducing heat stress in the body of the workpiece, reducing graphite consumption and specific energy consumption owing to a 40% reduction of the mass of additional components of the graphite articles.
