Problems solved by technology
[0003] The furnace hood of the existing rotatable metallurgical furnace is large in volume, occupies a large space, and is easy to accumulate dust. The furnace hood is cooled by a water jacket. The cooling water in the water jacket needs special cooling measures and cannot recover heat. Therefore, the use of the existing furnace hood Short life, and inconvenient process maintenance and adjustment

The invention discloses a furnace cover of a rotatable metallurgical furnace and the rotatable metallurgical furnace with the furnace cover. The furnace cover of the rotatable metallurgical furnace comprises a first cover body, a second cover body and an inserting plate, wherein the first cover body is shaped like a straight tube, the lower end face of the first cover body is arc-shaped, and a main smoke outlet is formed in the upper end of the first cover body; the second cover body is arc-shaped, the upper end of the second cover body is connected with the side wall at the lower end of the first cover body, the lower edge of the second cover body and the lower end face of the first cover body are located on the same circumference, an emergent smoke outlet is formed in the second cover body, and a radial inserting hole formed between the emergent smoke outlet and the upper end of the second cover body is formed in the second cover body; and the inserting plate is movably arranged in the radial inserting hole along the radial direction. The furnace cover of the rotatable metallurgical furnace, disclosed by the embodiment of the invention, has the advantages of small size and occupied space, no ash deposition, good sealing performance, convenience in process overhaul and regulation and the like.
Description
technical field [0001] The invention relates to the field of metallurgy, in particular to a furnace cover of a rotatable metallurgical furnace and a rotatable metallurgical furnace with the same. Background technique [0002] Rotatable metallurgical furnaces, such as rotatable metallurgical furnaces, are commonly used equipment in the metallurgical industry. The rotatable metallurgical furnace is widely used in the smelting of non-ferrous metals. During the smelting process, in order to effectively recover the waste heat of the rotatable metallurgical furnace, a waste heat boiler is installed above the smoke outlet of the rotatable metallurgical furnace. The waste heat boiler passes through the furnace cover and the rotatable The metallurgical furnace is connected so that the high-temperature flue gas enters the waste heat boiler from the rotatable metallurgical furnace, so that the heat in the high-temperature flue gas can be recovered through heat exchange. [0003] The f...
