  • Patent number: 4841542
    Abstract: An electric furnace includes a furnace vessel arranged on a furnace platform and 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 pivotably mounted lateral of the furnace vessel and including at least one lid bracket is provided for lifting, lowering and pivoting the furnace lid. In order that the high-current cables are only slightly twisted when pivoting the furnace lid, despite the pivot axis for the furnace lid being arranged as close to the furnace vessel as possible, the lid supporting framework is pivotably connected with the furnace platform by an oscillating crank hinged to it.

  • Patent number: 4643404
    Abstract: A tiltable metallurgical vessel has a convexly curved bottom, and is supported on a cradle frame tiltably mounted on the base. In order to provide a metallurgical vessel of high operational safety in which the melt covers as short a path as possible during tapping, scumming is feasible in a simple way, the retention of a residual sump in the vessel is possible, at least one eccentrically arranged, closeable tap opening is provided in the bottom above a receptacle placeable into the tapping position. The tap opening is closeable by a closure flap pivotable by a lever. The lever is connected with a shaft for rotation therewith, a pressure medium cylinder is mounted on the cradle frame, and an actuation rod of sufficient length to reach beyond the radiation region of the receptacle enables the shaft to be rotatable by the cylinder through the actuation rod.
