The electric current enters the molten glass from the electrodes, joule heat is generated in the glass kiln, and the heating of the molten glass is completed. The initial mounting position of the electrodes determines to some extent the temperature inside the glass furnace. The determination of the position relationship between the electrode end face and the cell walls on the two sides is an important factor influencing the erosion of the cell walls, and the protrusion or the leveling of the electrode end face and the cell walls is more beneficial to prolonging the service life of the cell walls.
