Beschreibung
Zusammenfassung:	The invention provides a water-cooled cover working door. A working door body is suspended on the first side face of channel steel by arranging angle steel clamped on a pulley device, so that the working door body and a working door bottom plate are kept a gap away from each other without being contacted with each other, the phenomenon that the working door on a water-cooled cover always sticks to the working door bottom plate under the influence of the radiation of high-temperature molten steel and splashing of liquid steel slag in the smelting process of an LF is overcome, the problem that the working door cannot be opened is solved, and the performance of the water-cooled cover of the LF furnace is optimized.
