Process for carbon electrode manufacture

A process for extruding green carbon electrodes comprising forcing a mixture of a carbonaceous material and a binder selected from the group consisting of coal-tar pitch, petroleum pitch and synthetic resins, through an extrusion die while applying to the area of contact between said mixture of carbonaceous material and binder and said extrusion die an extrusion oil comprising between about 45 and about 75 parts by weight per 100 parts of a mixture of straight-chain paraffinic hydrocarbons having an average number of carbon atoms per molecule between about 16 and about 45 and a cylinder stock derived from crude petroleum.
