Abstract:
    An apparatus for shaping, by compacting, carbonaceous blocks formed by a carbonaceous paste based on a carbonaceous aggregate such as coke, anthracite or graphite, and an organic cokable binder such as tar and optional additives. The carbonaceous paste is introduced into a mould in which some of the walls are displaceable with respect to their initial position and there are successively applied to said paste at least one stress sigma n along an axis An, then at least one stress sigma n 1 along an axis An 1 which is not coincident with the axis An, then at least one stress sigma n 2 along an axis An 2 which is not coincident with the axis An 1, and so forth, repetitively, each stress sigma (i) being applied after at least partial suppression of the stress sigma (i-1). Use of the apparatus substantially enhances compactness of the carbonaceous blocks.
