METHOD AND FACILITY FOR TRANSFORMING A LIQUID-STATE METAL INTO A SOLID-STATE METAL

摘要

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.

1. A method for converting a metal in the liquid state into a fragmented metal in the solid state, on at least two tables which are mutually successive, comprising
pouring the metal in the liquid state on an upstream portion which is inclined in a downstream direction of a first receiving surface (7) of a first cooled table (4), vibrating the first table so that the metal moves toward a downstream end of the receiving surface of that first table, causing the metal to fall from the downstream end of the first table on an upstream portion of a second receiving surface (17) of a second cooled table (5), vibrating the second table so that the metal moves toward a downstream end of the receiving surface of that second table, passing the metal below at least one rotary transverse fragmentation roller (102) which is positioned above a downstream table which is located downstream of the first table (5), vibrating the last table so that the metal moves toward a downstream end of the receiving surface of that downstream table, and discharging the fragmented and solidified metal at the downstream end of the receiving surface of that downstream table.
