摘要： 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. The lid supporting framework, under formation of a coupler, either is hinged to the furnace platform by means of a further oscillating crank under formation of a four-bar linkage or is guided with by one point along a guide arranged on the furnace platform under formation of a thrust crank.
摘要翻译：一种电炉包括设置在炉平台上的炉容器，其被可升降的盖子所覆盖，所述炉盖可由盖提升机构降下，并可从所述炉容器上方的位置转动到所述炉容器的侧面位置，枢转机构。提供了用于提升，降低和枢转炉盖的盖支撑框架，其可枢转地安装在炉容器的侧面并且包括至少一个盖支架。为了使高电流电缆在旋转炉盖时仅略微扭曲，尽管炉盖的枢转轴线尽可能靠近炉容器设置，但是盖支撑框架与炉平台可枢转地连接，摆动曲柄铰链到它。在形成耦合器的情况下，盖支撑框架或者通过在四杆连杆形成下的另一个摆动曲柄铰接到炉平台，或者沿着布置在炉平台上的引导件被引导一点的推力曲柄。

摘要： 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.
