Abstract
The invention relates to a movable closed cover for a refining furnace, which comprises a fixed support (1), wherein the fixed support (1) is arranged above the refining furnace, a fixed closed cover (2) and a movable closed cover (3) are arranged on the fixed support (1), the fixed closed cover (2) and the movable closed cover (3) are in butt joint to form a complete closed cover, the size of the movable closed cover (3) is larger than that of the fixed closed cover (2), the movable closed cover (3) can be used for sleeving the fixed closed cover (2) in, and the movable closed cover (3) can realize opening and closing actions of the refining furnace and the movable closed cover (3) when moving left and right on the fixed support (1). According to the movable closed cover for the refining furnace, the closed cover is not required to be removed, and the opening and closing actions of the refining furnace and the closed cover can be realized only by moving, so that the time for diffusing smoke dust is shortened, the dust collection efficiency is improved, and the field working environment is improved.
Description
Technical Field
The invention relates to a movable closed cover for a refining furnace, and belongs to the technical field of refining furnaces.
Background
The refining furnace is a smelting device in the hot working industry, and is mainly used for carrying out final deoxidation and alloying processes on molten steel in ferrous metallurgy.
At present, when steelmaking of a refining furnace is performed, a closed cover is generally required to be installed for dust collection, and the defect that when ingredients are added to molten steel, the whole closed cover is required to be removed, and dust collection equipment is not arranged in the removal process, so that a large amount of smoke dust is diffused, and the surrounding working environment is polluted.
Disclosure of Invention
The invention aims to solve the technical problem of providing the movable closed cover for the refining furnace, which does not need to remove the closed cover and can realize the opening and closing actions of the refining furnace and the closed cover only by moving, thereby shortening the time of smoke diffusion, improving the dust collection efficiency and improving the field working environment.
The invention solves the problems by adopting the following technical scheme: the utility model provides a refining furnace is with removing airtight cover, it includes the fixed bolster, the fixed bolster is arranged in the refining furnace top, be provided with fixed airtight cover and remove airtight cover on the fixed bolster, fixed airtight cover and remove airtight cover butt joint and form a complete airtight cover, remove airtight cover's size and be greater than fixed airtight cover, remove airtight cover can with fixed airtight cover suit in, remove airtight cover and can realize the action of opening and shutting of refining furnace and removal airtight cover when moving about on the fixed bolster.
Preferably, the fixed support is provided with a track, the bottom of the movable closed cover is provided with a traveling assembly, and the traveling assembly is matched with the track.
Preferably, the left end and the right end of the movable closed cover are sealed by high-temperature-resistant soft curtains.
Compared with the prior art, the invention has the advantages that:
according to the movable closed cover for the refining furnace, the fixed closed cover and the movable closed cover are in a movable sleeving mode, so that the butt joint of the fixed closed cover and the movable closed cover is easy, the movable closed cover is moved to the position above the fixed closed cover during overhauling of the refining furnace, the cover body is not required to be disassembled, and the opening and closing actions of the refining furnace and the closed cover can be realized only by moving, so that the time for diffusing smoke dust is shortened, the dust collection efficiency is greatly improved, and the field working environment is improved.
