ABSTRACT:
In a method of impregnating carbon electrodes, a step of heating and drying carbon electrodes is separately juxtaposed to a step of pitch impregnation and cooling so that respective palettes are transported on separate courses for the respective steps, and at a position where said courses approach each other, the electrodes are transferred from a palette for said heating and drying step to a palette for said impregnation and cooling step so that the palette in the step of impregnation and cooling does not pass through a heating and drying furnace in the other step.
