SELF-BAKING ELECTRODE UPPER-END DETECTION APPARATUS AND SELF-BAKING ELECTRODE UPPER-END MANAGEMENT METHOD

摘要

Provided is a self-baking electrode upper-end detection apparatus with which the upper end of a self-baking electrode can be detected automatically, accurately, and safely. The self-baking electrode upper-end detection apparatus (40) is provided with: a protection tube (50) that is disposed in an anchored state within an electrode case (20), and the lower end of which is positioned higher than the upper end of an electrode energizing section (30); a measurement tube (60) that is disposed so as to be inserted through the protection tube (50); and an air cylinder (70) for lowering the measurement tube (60) with a constant pressure, from the initial position thereof to where the lower end (61) of the measurement tube (60) hits a self-baking electrode (10) and stops. The air cylinder (70) is actuated so as to lower the measurement tube (60) until the tube stops, and an evaluation is made as to whether the stopping position of the lower end (61) of the measurement tube (60) is within a management range (R).
