PROCESS OF FORMING COPPER ANODES

摘要

The present invention relates to a process of forming copper anodes (6) in a casting wheel (I) from the stage in which the copper is in liquid molten state (5) in a dumping chute (3) and is transferred to a ladle (4) until the anode (6) of solid copper is transformed into an anode (6) and is discharged from a mould (2) located in said casting wheel (I) wherein said process prevents the liquid molten copper (5) from being adhered to the edge of the ladle (4) and in the interstice (14) generated between the surfaces of the ejector rod (13) and the passing through bore (12) located on the mould (2) comprising the stages of: pouring the molten liquid copper from a distributing dumping chute (3) towards a ladle (4); (b) connecting the metallic components of the ladle (4) to the ground in order to produce positive charge (17); (c) spraying towards the edge (lip) of the ladle (4) an air jet (19) with dry dusting release agent (20) which is expelled by a nozzle (21) charging the particles of said dry dusting (20) with high voltage and negative charge the particles of said dry dusting release agent (20) with high voltage and negative charge (18); (f) pouring the molten liquid copper (5) from the ladle (4) towards the cavity (II) of a mould (2) of anodes; (g) waiting until the copper gets cold in order to form the anode (6) by means of the turn of the casting wheel (I); (h) driving the ejector rod (13) to expel the anode (6) from the cavity (II) of the mould (2); and (i) removing the anode (6) from the mould (2) by means of cranes. The nozzle (21) is moved over the ladle zone (4) and mould zone (2) by means of a robotic arm (22) which is mounted on a cart (24) suspended above the casting wheel (I).(18); (b) connecting the metallic components of the mould (2) to the ground in order to produce a positive charge (17); (e) spraying towards the cavity (II) of the mould (2) and towards the location zone of the ejector rod (13) dry dusting release agent (20) through an air jet (19) which passes through a nozzle (21) which charges the particles of said dry dusting release agent (20) with high voltage and negative charge (18); (f) pouring the molten liquid copper (5) from the ladle (4) towards the cavity (II) of a mould (2) of anodes; (g) waiting until the copper gets cold in order to form the anode (6) by means of the turn of the casting wheel (I); (h) driving the ejector rod (13) to expel the anode (6) from the cavity (II) of the mould (2); and (i) removing the anode (6) from the mould (2) by means of cranes. The nozzle (21) is moved over the ladle zone (4) and mould zone (2) by means of a robotic arm (22) which is mounted on a cart (24) suspended above the casting wheel (I).

1: A process of forming copper anodes (6) in a casting wheel (1) from the stage in which the copper is in liquid molten state (5) in a dumping chute (3) and is transferred to a ladle (4) until the solid copper is transformed into an anode (6) and is discharged from a mould (2) located in said casting wheel (1) characterized in that said process prevents the liquid molten copper (5) from being adhered to the edge of the ladle (4) and in the interstice (14) generated between the surfaces of the ejector rod (13) and the passing through bore (12) located on the mould (2), the process comprising the stages of:
(a) pouring molten liquid copper from a distributing dumping chute (3) towards a ladle (4); (b) connecting the metallic components of the ladle (4) to the ground in order to produce a positive charge (17); (c) spraying towards the edge of the ladle (4) an air jet (19) with dry dusting release agent (20) which is expelled by a nozzle (21) charging the particles of said dry dusting (20) with high voltage and negative charge (18); (d) connecting the metallic components of the mould (2) to the ground in order to produce a positive charge (17); (e) spraying towards the cavity (11) of the mould (2) and towards the location zone of the ejector rod (13) dry dusting release agent (20) through an air jet (19) which passes through a nozzle (21) which charges the particles of said dry dusting release agent (20) with high voltage and negative charge (18); (f) pouring molten liquid copper (5) from the ladle (4) into the cavity (11) of an anode mould (2); (g) waiting until the copper gets cold in order to form the anode (6) by means of the turn of the casting wheel (1); (h) driving the ejector rod (13) to expel the anode (6) from the cavity (11) of the mould (2); and (i) removing the anode (6) from the mould (2) by means of cranes.
