ABSTRACT:
An electric furnace includes a furnace vessel covered by a furnace lid liftable and lowerable by a lid lifting mechanism and pivotable from a position above the furnace vessel into a position lateral of the furnace vessel and back by a lid pivoting mechanism. A lid supporting framework is pivotably mounted lateral of the furnace vessel and includes at least one lid bracket extending over the furnace vessel for lifting, lowering and pivoting the furnace lid. In order to be able to pivot the lid bracket without furnace lid and without necessitating manipulations to be carried out at the furnace lid for the purpose of exchanging the lid or the lid core, the lid bracket is detachably connected to the furnace lid by at least one coupling means, with a coupling piece of the coupling means being arranged on the lid bracket and a coupling counter piece of the coupling means being arranged on the furnace lid. The coupling piece or the coupling counter piece includes a lateral recess extending in the pivoting direction of the lid supporting framework, through which the coupling counter piece is capable of being assembled with the coupling piece from aside.
