Abstract
The utility model relates to a device for producing monocrystal copper rods in a multiwire method. Because the utility model uses a structure that a valve mechanism is arranged on a communicating position of a horizontal liquid passing pipe and a smelting furnace, and therefore, when a jet of leakage liquid is leaked out or a mold is replaced, each of the rest jets can be still operated normally, and productive continuity can be ensured. Moreover, the utility model can enable a plurality of air bubbles to be contained in the smelting furnace and copper liquid in the upper layer of inclusions not to directly enter the horizontal liquid passing liquid, and thereby, the quality of copper rods can be improved. In addition, because the utility model is also provided with a stirring deoxidation device, and therefore, the utility model not only can enable the temperature of copper liquid in the smelting furnace to be kept to be uniform and identical, but also can speed up the process of deoxidation. Monocrystal copper rods which are produced by the utility model not only can be successfully used for six kinds of computer network lines, but also can be used for producing superfine copper wires, and the diameter of each of the copper wires is under 0.005 mm.
