 characterized in that   the transformer is fixedly disposed at the furnace head.   
     
     
         2 . The furnace according to  claim 1 ,
 characterized in that   the supports ( 39 ) are formed column-shaped and form at least one bearing plane ( 40 ) of the furnace head ( 41 ) together with horizontal bearings.   
     
     
         3 . The furnace according to  claim 1  or  2 ,
 characterized in that 
 the transformer ( 42 ) is fixedly disposed on the bearing plane ( 40 ). 
 
     
     
         4 . The furnace according to one of the preceding claims,
 characterized in that   at the furnace head ( 41 ), a contact device ( 44 ) for transmitting the electric power to the electrode, an electrode rod and/or a bottom plate of the crucible is formed, wherein the transformer ( 42 ) is disposed directly adjacent to the contact device.   
     
     
         5 . The furnace according to  claim 4 ,
 characterized in that   the transformer ( 42 ) is fixedly disposed relative to the contact device ( 44 ).   
     
     
         6 . The furnace according to  claim 4  or  5 ,
 characterized in that 
 the transformer ( 42 ) is connected to the contact device ( 44 ) by means of a rigid busbar device ( 43 ). 
 
     
     
         7 . The furnace according to one of the preceding claims,
 characterized in that   the furnace head is formed stationary, and the crucible has a bottom plate which is movable relative to the furnace head.   
     
     
         8 . The furnace according to one of the  claims 1  to  6 ,
 characterized in that 
 the bottom plate is formed stationary, and the furnace head ( 41 ) is formed horizontally movable relative to the crucible. 
 
     
     
         9 . The furnace according to one of the  claims 1  to  6 ,
 characterized in that 
 the crucible has a stationary bottom plate, and the furnace head is formed stationary relative to the bottom plate. 
 
     
     
         10 . The furnace according to one of the preceding claims,
 characterized in that   the furnace ( 37 ) is configured for electroslag remelting under vacuum, under inert gas, under air atmosphere or under pressure.   
     
     
         11 . A method for electroslag remelting with a furnace ( 37 ), wherein the furnace comprises a base frame ( 38 ), wherein the base frame comprises supports ( 39 ) which bear a furnace head ( 41 ), wherein at the furnace head, an electrode is disposed, wherein the electrode is melted on in a crucible disposed below the furnace head, wherein the electrode is melted on into the crucible by means of a feed movement of the electrode, wherein the furnace comprises a transformer ( 42 ) which supplies electric power for melting on the electrode,
 characterized in that   the transformer is moved together with the furnace head.
