Abstract
The present invention relates to a method for continuous production of elongated carbon bodies having substantial uniform cross-section where a casing filled with unbaked carbonaceous electrode paste is slowly and substantially continuously lowered down through a baking furnace having an external energy supply. The casing is perforated in order to allow baking gases to flow from the electrode paste and into the baking furnace. Air for combustion of the baking gases is supplied to the baking furnace in an amount necessary for combustion of the baking gases which flow into the baking furnace. The external energy supplied to the baking furnace is controlled in such a way that the total amount of external energy supplied to the baking furnace and the energy generated by combustion of the baking gases inside the baking furnace is sufficient to maintain a temperature inside the baking furnace of 700.degree.-1300.degree. C., preferably 900.degree.-1100.degree. C.
