Abstract
Melting furnace (1), in particular for the production of metal alloys by melting alloying constituents, with a melting crucible (10), a cylindrical electrode rod (40) with a consumable electrode (41) attached thereto and a power supply (50) that is configured to supply the electrode (41) with power via the electrode rod (40), wherein the electrode rod (40) can be rotated about its own axis and moved along its own axis during the melting process.
Claims18
A melting furnace (1), in particular for producing metal alloys and non-ferrous alloys, comprising:
- an electrode rod (40) with a consumable electrode (41) attached thereto, the consumable electrode comprising alloying constituents to be remelted;
- a melting crucible (10);
- and
- a power supply (50) that is configured to supply the consumable electrode (41) with power via the electrode rod (40),
- wherein the electrode rod (40) is rotatable about a longitudinal axis and can be moved along the longitudinal axis during a melting process and
- wherein a remelted ingot comprising the alloying constituents is formed in the melting crucible during the melting process, and
- wherein the melting furnace (1) is configured to simultaneously rotate the electrode rod (40) about the longitudinal axis and oscillate the electrode rod (40) along the longitudinal axis during the melting process.
A melting furnace (1), for producing metal alloys and non-ferrous alloys by melting alloying constituents, comprising:
- a furnace column (62);
- a melting crucible (10);
- a furnace hood (20) which is configured to close the melting crucible (10), the furnace hood (20) being held on movably guided by the furnace column (62);
- an electrode carriage (30) held on and movably guided by the furnace column (62);
- an electrode receptacle (31) attached to the electrode carriage (30);
- an electrode rod (40) with a consumable electrode (41) attached to the electrode receptacle (31);
- and
- a power supply (50) that is configured to supply the consumable electrode (41) with power via the electrode rod (40),
- wherein the electrode rod (40) is rotatable about a longitudinal axis and can be moved along the longitudinal axis during a melting process, and
- wherein the consumable electrode (41) is immersed in the melting crucible (10) through a bushing (21) in the furnace hood (20), and
- wherein the furnace hood (20) is attached to the electrode carriage (30) by a hydraulic cylinder (23), the hydraulic cylinder (23) being configured to adjust a relative distance between the furnace hood (20) and the electrode carriage (30).
