The reverberatory furnace is a traditional forging equipment, which is widely used in forging copper and lead. The structure of the reverberatory furnace consists of eight parts: furnace bottom, furnace wall, furnace top, charging port and converter slag injection port, discharge port, working door, flue, and fire bridge.

(1) Furnace bottom: According to the positional relationship between the bottom and the bottom, it can be divided into a hanging bottom and a solid bottom; according to the structure of its bottom, it can be divided into a brick-built reverse arch furnace bottom and a sintered integral furnace bottom. The smelting, smelting and reverberatory furnaces commonly used in production mostly use a brick-built reverse arch furnace bottom, and its thickness is usually between 700-900 mm.

(2) Furnace wall: The furnace wall is placed directly above the furnace bottom. The inner layer of the melting reverberatory furnace is made of magnesia bricks and magnesia-alumina bricks, the outer layer is clay bricks, and some important parts are chrome-magnesia bricks. The inner and outer walls of metal kilns with relatively low melting points, such as aluminum melting furnaces, can be made of clay bricks.

(3) Furnace roof: The reverberatory furnace roof structure is divided into brick-built arch and hanging furnace roof. The hanging furnace roof can be further divided into: simple ceiling, pressure beam thrust ceiling and vertical rod thrust ceiling.

(4) Feeding port and converter slag injection port: The size of the feeding port depends on the conditions of the charge. The charging port on the top of the furnace is generally made into a water jacket type. When the converter slag needs to be processed in the copper smelting reverberatory furnace, the injection port should be set at the front end so that the slag flow direction is as parallel to the side wall as possible to avoid impact and damage to the material slope.

(5) Discharge port: ① Hole-type product discharge port ② Slot-type product discharge port. For periodic operation reverberatory furnaces, if there are multiple layers of melt such as slag, matte and crude metal in the furnace at the same time, the slot-type product discharge port is mostly used. ③ Siphon-type product discharge. The siphon-type product discharge port has the advantages of convenient and safe operation, which can improve working conditions, reduce labor intensity, and improve product quality.

(6) Working door: The periodic reactor is provided with a working port for feeding, plugging in oxidation blowpipes, reduction pipes, oxidation-reduction, solvent addition, etc. Working door, working door, working door, depending on the size of the furnace. The working door of the present invention is used to transport furnace building materials and for workers to enter and exit during the construction process, and is filled with the same refractory bricks before ignition. The furnace wall above the slag line of the molten pool is generally equipped with a working door.

(7) Flue: The periodic reverberatory furnace usually adopts a vertical flue. When the furnace width is not large and the vertical part of the vertical flue is not high, it can be directly pressed on the vault of the furnace. Here, the vault can adopt a "reinforced arch ring" to bear the load of the flue.

(8) Fire bridge: The periodic reverberatory furnace with a coal-burning fire chamber has a fire bridge that is easily eroded and damaged during the production process. Generally, better refractory materials are used for masonry and water jackets or natural cooling air ducts are installed on the wall. Therefore, the masonry of the fire bridge is relatively thick. The fire bridge should not be too high to prevent low-temperature dead corners.

It can be seen that the reverberatory furnace has a simple structure, is easy to operate and control.
