[0029] Such as figure 1 shown, including the following steps:
[0030] Step S10, such as figure 2 , Figure 4 As shown, copper material 10 (electrolytic copper) is added into a smelting device and melted to obtain molten copper. Wherein, the smelting device includes a preheating furnace 20 , a melting furnace 30 , a chute 110 , and a first holding furnace 40 connected in sequence. The combustible gas is fed into the preheating furnace 20, and the copper material 10 is transported to the preheating furnace 20 for combustion and preheating, and the surface attachments of the copper material 10 are burned off. Specifically, the incomplete combustion reaction (partial cracking) is carried out in the preheating furnace 20, and the incomplete combustion reaction is an exothermic reaction, so the preheating furnace 20 does not need external heat energy, and the heat generated by its own combustion can make the reaction continue. . The preheating furnace 20 and the melting furna...

[0038] Such as image 3 , Figure 5 As shown, on the basis of the first embodiment, a second hollow crystallizer 120 is also provided. When the output speed of the first primary casting rod is greater than the output speed of the intermediate casting rod, the copper liquid is also controlled to crystallize to the second hollow The device 120 transports. Specifically, a second hollow crystallizer 120 is installed in the second holding furnace 90, and the copper liquid 100 is condensed into a solid in the second hollow crystallizer 120, and the upper end of the solid is pulled upward by a traction mechanism to form a second primary casting rod. The second primary casting rod undergoes a cold rolling process and a coil forming process to produce a finished copper rod. Specifically, since the first hollow crystallizer 80 needs to ensure a certain output speed when crystallizing the first primary casting rod. The output speed of the produced first primary cast rods may be faster...
