Benefits of technology

The present invention proposes a method for electroslag remelting which is more cost-effective and efficient. The technical effects of the invention include the use of a fixed transformer, eliminating the need for flexible cables and reducing the power consumption of the furnace. The transformer can be easily connected to the contact device using a rigid busbar device. The furnace can be used for different processes under different atmospheres.

Problems solved by technology

Although, initially, there are higher costs for forming the base frame since it has to bear the transformer, these costs are outweighed by sparing the high-current cables and by the reduced operating costs.

Embodiment Construction

[0026]FIG. 1 shows a furnace 10 for electroslag remelting (ESR) under inert gas according to the state of the art. A base frame 11 forms a bearing plane 12 of a furnace head 13, wherein the bearing plane 12 and the furnace head 13, respectively, are mounted on supports 14. The furnace head 13 comprises a feed drive 15 for an electrode 16 with a spindle 17 and an electrode suspension 18 as well as an electrode rod 19 which connects the electrode 16 to the electrode suspension 18. Furthermore, by means of the base frame 11, two walkable platforms 20 and 21 are formed. Below the furnace head 13, a crucible 22 is disposed in which an ingot 23 and a melting bath 24 are already present. A bottom plate 25 of the crucible 22 is stationarily, that is fixedly, disposed on a base 26. Furthermore, above the crucible 22, a protective gas chamber 27 is formed which makes it possible to melt on the electrode 16 under protective gas. In a separate room 28, which is only illustrated partly here, a t...
