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).

Abstract: Method and installation for converting a metal in the liquid state into a fragmented metal in the solid state. The metal in the liquid state is poured on an upstream portion of a receiving surface (7) of a first cooled vibrating table (4). The metal falls from the downstream end of the first table on an upstream portion of a receiving surface (17) of a second cooled vibrating table (5). The fragmented and solidified metal is discharged at the downstream end of the receiving surface of that second table. A rotary fragmentation roller (102) may be positioned above a table. The tables comprise an upstream cooling zone (7) by means of a liquid/gas emulsion and a downstream cooling zone (17) by means of a liquid.

Abstract: A contact plate intended to be brought into contact with the wall of an electrode of an electro-metallurgical furnace, comprising an internal channel having an inlet and at least one outlet which can be linked respectively to an external supply conduit and at least one external discharge conduit for a fluid. According to the invention, at least one elongate hole (16) is provided, inside which an elongate partition (35) is installed that has opposing elongate edges (39) adjacent to opposing elongate areas (33) of the elongate hole so as to define, in said hole, elongate spaces (16a-16b) to either side of the elongate partition, the elongate partition defining a communication passage (41) between said elongate spaces and connecting holes (29) communicating with said elongate spaces being provided at a distance from said communication passage, said elongate spaces forming portions of said internal channel (59).
