Problems solved by technology

[0005] The purpose of the present invention is to provide a water-cooled furnace cover working door to solve the problem that the water-cooled furnace cover is directly affected by the radiation of high-temperature molten steel and the splash of liquid steel slag in the prior art, so that the working door on the water-cooled furnace cover is often stuck to the working door. On the bottom plate of the door, the work door cannot be opened, which reduces the work efficiency

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of iron and steel smelting, in particular to a water-cooled furnace cover working door. Background technique [0002] The water-cooled furnace cover is the core equipment of the LF furnace (ladle refining furnace), and its use will directly affect the working status of the entire LF furnace and even the entire steelmaking workshop. Usually, working doors such as temperature measurement sampling door, gun hole door and operation door are set on the water-cooled furnace cover to cooperate with the processes of temperature measurement sampling, top blowing argon, adding alloy auxiliary materials, etc. These working doors are opened during work and closed during standby . The working door is welded by water pipes. The working door is close to the bottom plate of the working door, and is opened or closed by the drive of the cylinder. [0003] However, because the water-cooled furnace cover is directly affected ...
