Abstract
Apparatus for the production of metal including a furnace for melting metal provided with a crucible inside which a metal charge is melted. The furnace provides for tapping a liquid metal disposed on the bottom of the crucible and includes a tapping channel for the transfer of the liquid metal from the furnace. The apparatus also includes a delivery unit for delivering inert material (S) having a delivery device for the selective delivery of the inert material (S) into the tapping channel.
Claims13
A method to produce metal in a melting furnace, comprising at least one step of filling a tapping channel of a furnace for melting metal provided with a crucible inside which a metal charge is melted, and with a covering panel disposed on an upper part, said furnace being provided with means for tapping a liquid metal disposed on a bottom of said crucible and comprising the tapping channel for transferring said liquid metal from said furnace, wherein
- a delivery unit for delivering inert material (S) comprises a delivery device for selective delivery of the inert material (S) into said tapping channel, and
- a hatch unit is disposed on said covering panel and configured to allow access to the inside of said crucible for the delivery of said inert material (S), and
- wherein said delivery unit comprises support means configured to rotatably support said delivery device in order to take it from an operative condition, in which it faces toward said furnace and is aligned with said hatch unit, to a stand-by or parked condition in which it is disposed outside a bulk of the furnace, and vice versa, wherein the hatch unit comprises a support plate, stably attached to the covering panel, and provided with an aperture and a closing door, configured to allow or prevent access to the aperture, said closing door being provided with a central aperture and an access panel configured to selectively at least partially open and close the central aperture, and
- wherein the delivery unit is supported and moved in rotation by the support means outside said furnace, at least from the stand-by or parked condition, in which said delivery device is disposed outside the bulk of the furnace, to the operative condition, in which said delivery device is at least partly above the covering panel of the furnace being able to cooperate with said tapping channel, and vice versa.
An apparatus for the production of metal comprising:
- a furnace for melting metal provided with a crucible inside which a metal charge is melted, and with a covering panel disposed on an upper part, said furnace being provided with means for tapping a liquid metal disposed on a bottom of said crucible and comprising a tapping channel for transferring said liquid metal from the furnace,
- a unit for delivering inert material (S) comprising a delivery device for selective delivery of the inert material (S) into said tapping channel,
- a hatch unit disposed on said covering panel and configured to allow access to the inside of said crucible for the delivery of said inert material (S), wherein said delivery unit comprises support means configured to rotatably support said delivery device in order to take it from an operative condition, in which it faces toward said furnace and is aligned with said hatch unit, to a stand-by or parked condition in which it is disposed outside a bulk of the furnace, and vice versa, wherein the hatch unit comprises a support plate, stably attached to the covering panel, and provided with an aperture and a closing door, configured to allow or prevent access to the aperture, said closing door being provided with a central aperture and an access panel configured to selectively at least partially open and close the central aperture.
An apparatus for the production of metal comprising:
- a furnace for melting metal provided with a crucible inside which a metal charge is melted, and with a covering panel disposed on an upper part, said furnace being provided with means for tapping a liquid metal disposed on a bottom of said crucible and comprising a tapping channel for transferring said liquid metal from the furnace,
- a unit for delivering inert material (S) comprising a delivery device for selective delivery of the inert material (S) into said tapping channel,
- a hatch unit disposed on said covering panel and configured to allow access to the inside of said crucible for the delivery of said inert material (S), wherein
- said delivery unit comprises support means configured to rotatably support said delivery device in order to take it from an operative condition, in which it faces toward said furnace and is aligned with said hatch unit, to a stand-by or parked condition in which it is disposed outside a bulk of the furnace, and vice versa, wherein the hatch unit comprises a support plate, stably attached to the covering panel, and provided with an aperture and a closing door, configured to allow or prevent access to the aperture, said closing door being provided with a central aperture and an access panel configured to selectively at least partially open and close the central aperture, wherein the access panel is configured to pass from a closed position, in which it is substantially parallel to the closing door and prevents access to the central aperture, to an open position, in which it is inclined with respect to the closing door allowing access to the central aperture for the introduction of the inert material (S) by the delivery device.
