The invention discloses a closed-running secondary element continuous smelting anode copper production line. The production line comprises a multi-element smelting furnace, a fire finishing furnace, acasting disc and a flow guiding groove. The production line is characterized in that through dynamic regulation of the arrangement mode, the position and the jet direction and the type and ratio of the gas supply of the multi-element smelting furnace and a spray gun of the fire finishing furnace, the intensity and the depth of the reaction process are improved, the movement mode and the rate of copper matte are improved, the copper-containing 75%-78% of the sub-white matte is produced by the multi-element smelting furnace, and the fire finishing furnace produces an anode copper with copper content greater than 99.2%; the closed flow guiding groove is arranged among the multi-element smelting furnace, the fire finishing furnace and the casting disc, the copper matte is conveyed without interruption, and ingot casting production of anode copper is accomplished. Compared with the prior art, production equipment for the secondary element continuous smelting anode copper is less, the arrangement and installation are compact, the flow is short, the construction investment is saved, the operation cost is low, the energy is saved, the environment is protected, the safety is achieved, andtherefore, the production line has very good popularization and use value.
