The rotary anode copper melting furnace consists of three parts: furnace body, supporting device and driving device. The furnace body consists of a simplified body, masonry, furnace cover, combustion device, short exhaust pipe, etc. The size of the furnace body is related to the required amount of crude copper and crude copper slag per furnace. In addition, the maximum heat load suitable for the rotary anode furnace should also be considered. The cylinder size of the rotary anode furnace is related to the thickness of its brickwork. Since the rotary anode furnace needs to rotate during the casting process, the brickwork thickness cannot be too large, otherwise it will increase the driving power and the cylinder wall thickness; if the brickwork is too thin, in addition to affecting the furnace life and the cylinder surface temperature is too high, it also increases the heat dissipation and has a great impact on the strength of the supporting device and the roller.
Generally, the thickness of brickwork can control the surface temperature of the cylinder at 200~240℃. The heavy oil burning port is used as the boundary. A charging port and an oxidation-reduction port are opened on one side, and a copper outlet is opened on the other side. The arrangement of the ports is related to the process configuration. The angles between the ports have little to do with their diameters, but mainly depend on the rotation angle required by the process. It is convenient for the process operation requirements of oxidation, reduction and copper outlet.
The size of the furnace mouth mainly depends on the requirements of the crude copper loading operation and the size of the returned residual anode. Under the condition of meeting the loading requirements, the size of the furnace mouth should be reduced as much as possible, because one of the biggest advantages of the rotary anode furnace is that the furnace body has good air tightness, and the overflow and radiation heat loss of the orifice during the operation process is small. If the opening is too large, it will affect the thermal efficiency of the furnace. Moreover, if the size of the furnace mouth is too large, it will not only increase the difficulty of processing and manufacturing the furnace mouth water cooling parts, but also cause the furnace mouth lining bricks of the rotary anode copper melting furnace to collapse easily.
