Temperatures were measured with K-type thermocouples in two electrodes in an industrial FeMn furnace.Themeasurements were taken over a period of16days with seven measurement days,including one furnace shutdown andstart up.The temperature profiles show a temperature rise from50to70℃in the area of the paste level.Furtherdowning of the electrode induced current from the current bars heat up the paste above the contact clamps.Differentlypositioned measurement points on the circumference of the electrode show large differences in paste temperature.Inone measurement position between the fins of the casing,temperatures reach up to270℃C due to induction,and atthese temperature volatiles may start to leave the coal-tar pitch going upward through the melted electrode paste.Thevolatiles may condensate again,and hence decrease the coal-tar pitch viscosity which again increases the chance ofsegregation in the paste.The highest temperature is found between the steel fins because heat conduction by the steeldecreases temperature gradients close to the fins.The need for heat conduction by steel fins can also be seen in a COMSOL computer model where the steel fins are not included,and better heat conduction would improve the model.During high slipping before a furnace shutdown the position of the baking zone is moved down,but stays within thecontact clamp.Temperatures in the electrode need more than12hours to recover after a shutdown of 8 hours.
