Abstract
Contact plate for placing in contact with the wall of an electrode of an electro-metallurgical furnace. The contact plate includes an internal channel having an inlet and at least one outlet. The inlet and outlet are respectively linked to an external intake duct and to at least one external duct for discharging a fluid. An elongate hole (16) has an elongate partition (35) which has opposing elongate edges (39) adjacent to opposing elongate zones (33) of the elongate hole so as to define, in the hole, elongate spaces (16a-16b) on either side of the elongate partition. The elongate partition defines a connecting passage (41) between the elongate spaces and link holes (29) communicating with the elongate spaces being formed at a distance from the connecting passage. The elongate spaces form portions of the internal channel (59).
