Problems solved by technology
However, this method is very troublesome, and when putting in, it is necessary to remove the charcoal or graphite layer on the copper liquid, so some oxygen will be brought in, resulting in poor product effect
[0006] What needs to be pointed out is that it has been found through research that impurity removal and oxygen removal and dehydrogenation are a gradual process. Adding oxygen, dehydrogenation and impurity removal agents in stages will achieve better results, but the existing method is based on smelting Time, adding these substances several times, resulting in the surface solution quality is not good enough

Embodiment Construction
[0035] It should be pointed out that because the production system is relatively complicated, the applicant simplified or omitted some details without improvement, and these technical knowledge is the prior art in this field.
[0036] Such as figure 1 As shown, the production line for producing copper wire rods of the present invention includes hoist a, melting furnace b, holding furnace c, continuous casting machine d, hydraulic shear e, shaping ingot casting machine f, rough Rolling mill g, flying shear h, finishing mill i, pickling machine j, coiler k, and transport vehicle L; the hoist lifts the feed vehicle to a certain height and sends it to the melting furnace for melting. After the molten copper is melted and refined, it is sent to into the holding furnace, and further sent to the continuous casting machine for casting. After the rough products produced by the continuous casting machine are processed by the hydraulic shear and shaping ingot casting machine, they are se...

The invention discloses a catapult type deoxygenation and dehydrogenation device for oxygen-free copper production, which comprises: a head made of pure copper, the outer surface of which is covered with a graphite layer; a pipe body with a pipe wall made of pure copper, and The head is connected, one end of the tube body is open, there is an accommodation space inside, and the outer circumference is covered with a graphite layer; the sealing cover is used to seal the open end of the tube body, and the outer circumference is provided with a graphite layer; several deoxygenation and dehydrogenation subunits , accommodated in the accommodating space, and there are copper separators between adjacent oxygen removal and dehydrogenation units. The present invention has the advantages of convenient feeding and control of the diffusion speed of the deoxygenation and dehydrogenation agent. It only needs to be added once to realize the impurity removal treatment in the whole process without multiple additions, thus reducing the chance of impurity entering the surface of the copper liquid and improving the oxygen removal rate. Advantages of the dehydrogenation effect.
Description
technical field [0001] The invention relates to a copper production device, in particular to a production line for producing copper wire rods. Background technique [0002] With the rapid development of my country's national economy in recent years and the continuous improvement of people's quality of life, the quality requirements for various products are becoming more and more stringent. Electric wires for automobiles, connecting wires for computers, connecting wires for instruments, enameled wires and magnet wires have high requirements on the overall performance of wire rods due to their small diameters. The quality of copper wire rods produced by continuous casting and rolling of waste copper in China is unstable, and the copper rods produced by the upward drawing method have high hardness, and the rate of end breaks in the wire drawing process is high. [0003] Therefore, higher and higher requirements are put forward for copper smelting productivity, cost and product...
