Continuously consumed electrodes are used in the manufacture of ferro alloys, aluminium, silicon metal and calcium carbide. The raw material for the electrodes is a carbon paste which is normally added to the electrode in large solid sections. The option of manufacturing such electrodes from small paste ‘briquettes’ is examined with respect to an industrial experiment used to predict the
