摘要: The present invention relates to a method for production of carbon electrodes where a first unbaked carbonaceous electrode paste containing a binder which cures at a temperature below 500.degree. C. is supplied to an annulus between a curing chamber having an inner cross section corresponding to the cross section of the electrode which is to be produced and an inner mould material, curing of the first electrode paste by means of supplying heat to the curing chamber, removing of elongated sections of the cured first electrode paste from the curing chamber. The lengths of the cured first electrode paste are mounted on the top of the electrode column in an electric smelting furnace, a second electrode paste is optionally supplied to the central opening of the cured body of the first electrode paste, whereby the cured body of the first electrode paste and the second electrode paste are baked into a solid carbon electrode in the area of supplying electric operating current to the electrode.
