Section: claims

1. A mobile melting device including a crucible base and a crucible chamber adapted to receive a crucible; comprising: the crucible base comprises a chamber bottom and the crucible chamber comprises a shell,wherein the device further comprises a transport means which is adapted to move the crucible base together with the crucible from a first position to a second position, wherein the crucible in said first position is disposed outside the crucible chamber and in the second position is disposed within the crucible chamber,wherein the chamber bottom and the shell are configured such that they form a gas-tight furnace enclosure in the second position,wherein the transport means with the crucible base and the crucible arranged thereon is movable such that crucible can be removed from the area below the crucible chamber and another crucible can be introduced into the crucible chamber,wherein the melting device comprises a charging device which is arranged above the crucible chamber, and wherein stabilizing elements are arranged within the crucible chamber, stabilizing the crucible during the melting process. 2. The melting device according to claim 1, wherein the charging device is gas-tight. 3. The melting device according to claim 1, wherein the crucible chamber comprises a heater that enables to heat the crucible. 4. The melting device according to claim 1, comprising a collecting pan which is arranged below the crucible in the crucible base. 5. The melting device according to claim 1, wherein the melting device is configured modular, comprising at least one chamber module, a charging module and a transport module. 6. A method for consolidating a material in a melting device according to claim 1, comprising the steps ofa. charging a crucible with a material to be consolidated;b. heating the material to be melted within the crucible, so that at least a part of the material to be melted melts,c. recharging an additional portion of material to be melted, andd. solidifying the molten material in the crucible to a block. 7. The method according to claim 6, wherein a non-oxidizing atmosphere prevails in the crucible chamber during the heating process. 8. The method according to claim 6, wherein the crucible during the process steps of heating, melting, recharging and solidifying is disposed within the crucible chamber. 9. The method according to claim 6, wherein the crucible is removed from the crucible chamber and cooled after the solidification and another crucible is introduced into the crucible chamber during the cooling process. 10. The method according to claim 6, wherein the oxygen partial pressure in the crucible chamber is less than 10 kPa. 11. The method according to claim 6, wherein the steps of charging, heating, melting and, optionally recharging, are carried out in a single crucible under vacuum and/or a controlled atmosphere. 12. The melting device according to claim 1, comprising stabilizing elements arranged within the crucible chamber to stabilize the crucible during the melting process. 13. The melting device according to claim 3, wherein the heater is an induction heater. 14. A mobile melting device including a crucible base and a crucible chamber adapted to receive a crucible; comprising: the crucible base comprises a chamber bottom and the crucible chamber comprises a shell,wherein the device further comprises a transport means which is adapted to move the crucible base together with the crucible from a first position to a second position, wherein the crucible in said first position is disposed outside the crucible chamber and in the second position is disposed within the crucible chamber,wherein the chamber bottom and the shell are configured such that they form a gas-tight furnace enclosure in the second position,wherein the transport means with the crucible base and the crucible arranged thereon is movable such that crucible can be removed from the area below the crucible chamber and another crucible can be introduced into the crucible chamber,wherein the melting device comprises a charging device which is arranged above the crucible chamber,and wherein the melting device comprises a collecting pan which is arranged below the crucible in the crucible base. 15. The melting device according to claim 14, wherein the charging device is gas-tight. 16. The melting device according to claim 14, wherein the crucible chamber comprises a heater that enables to heat the crucible. 17. The melting device according to claim 14, wherein the melting device is configured modular, comprising at least one chamber module, a charging module and a transport module. 18. A method for consolidating a material in a melting device according to claim 14, comprising the steps ofa. charging a crucible with a material to be consolidated;b. heating the material to be melted within the crucible, so that at least a part of the material to be melted melts,c. recharging an additional portion of material to be melted, andd. solidifying the molten material in the crucible to a block.
