The upper roller 11, the lower roller 12, the first block chain 13 and the second block chain 14 are arranged to form a casting cavity. When a solution is injected into the casting cavity, the desired ingot is formed under the action of the extrusion force to avoid hollowness. For example, copper liquid is injected into the casting cavity, and a copper ingot of a certain size is die-casted under the action of the extrusion force of the upper roller 11, the lower roller 12, the first block chain 13 and the second block chain 14. Among them, the upper roller 11 can be an upper steel strip, and the lower roller 12 can be a lower steel strip.

Based on this, the embodiment of the utility model is provided with a purging device 20 below the first block chain 13 and the second block chain 14. The purging device 20 blows air toward the first block chain 13 and the second block chain 14 to remove oxides on both sides of the first block chain 13 and the second block chain 14, such as copper oxide scale, to prevent the oxides from melting again and entering the ingot, reduce impurities in the ingot, and avoid wire breakage during the drawing process.

[0033] In the copper rod production system provided by the embodiment of the present utility model, the upper roller 11, the lower roller 12, the first block chain 13 and the second block chain 14 are arranged to form a casting cavity, and the liquid in the casting cavity forms a billet under the action of the extrusion force to avoid hollowness; by driving the upper roller 11 and the lower roller 12 to rotate, the first block chain 13 and the second block chain 14 rotate, and the billet moves forward; by arranging a purge device 20 below the first block chain 13 and the second block chain 14, the oxides on the first block chain 13 and the second block chain 14 are purged to avoid the oxides from melting again and entering the billet, thereby reducing impurities in the billet, thereby avoiding wire breakage during the drawing process and improving production efficiency and product quality.

[0038] The purge device 20 in the embodiment of the present invention also includes a fixed frame 24, a first guide wheel and a second guide wheel. The first guide wheel and the second guide wheel are spaced apart and are respectively rotatably connected to the fixed frame 24. It should be noted that the spacing between the first guide wheel and the second guide wheel is equal to the spacing between the first block chain 13 and the second block chain 14. The first guide wheel is used to support and guide the rotation of the first block chain 13. Specifically, the circumference of the first guide wheel is provided with a first limiting groove, and the first block chain 13 can move along the first limiting groove. The second guide wheel is used to support and guide the rotation of the second block chain 14.

It should be noted that the rotation speed of the first guide wheel 25 and the second guide wheel 26 is consistent with the rotation speed of the upper roller 11 and the lower roller 12.

[0040] The copper rod production system provided by the embodiment of the present invention also includes a tundish 30, which is a refractory material container for holding a solution, such as a copper solution. The outlet of the tundish 30 is connected to the casting cavity, and the solution in the tundish 30 can flow to the casting cavity through the outlet of the tundish 30 to form a billet. A filter is provided between the inlet and outlet of the tundish 30 to filter impurities in the solution and prevent impurities from entering the casting cavity, that is, to reduce impurities in the billet and prevent breakage during drawing. The filter can be arranged at the inlet of the tundish 30, or at the outlet of the tundish 30, or between the inlet and the outlet. Optionally, the filter is a filter brick, and the number of filter bricks can be 30-50ppi, such as 30ppi, 40ppi, 50ppi, etc. The filter in the embodiment of the present invention can be multiple, and multiple filter elements are spaced between the inlet and outlet of the tundish 30.

[0041] Impurities are easily generated at the corners of the ingot cast from the casting chamber. Therefore, in this embodiment of the utility model, a milling device is provided at the outlet of the casting chamber to perform milling on the ingot cast by the casting device 10. Specifically, the milling device includes a main milling cutter and an auxiliary milling cutter, which cooperate to mill the corners of the ingot and reduce impurities in the ingot.

[0042] The copper rod production system provided by the embodiment of the present invention also includes a melting furnace, a slag box 40, a holding furnace and a rolling mill. The melting furnace can melt the metal in the furnace into liquid metal, such as copper liquid. It should be noted that before loading, the first block chain 13 and the second block chain 14 need to be cleaned with a purge device 20 to remove impurities on the surface. Figure 3As shown, slag box 40 is provided with upper launder 42, lower launder and slag removal opening 41, wherein upper launder 42 is communicated with the outlet of melting furnace, copper liquid enters in slag box 40 through upper launder 42, can remove the scum in the copper liquid by slag removal opening 41, can be skimmed once at intervals of 2-3 hours.Copper liquid after cleaning enters in holding furnace through lower launder, and holding furnace plays the effect of buffering, temperature adjustment, oxygen reduction.In the production process, need regularly utilize oxygen analyzer that melting furnace, holding furnace and lower launder are carried out oxygen content detection, oxidation furnace oxygen content is controlled at 80-120ppm, holding furnace oxygen content is controlled at 160-180ppm, and lower launder oxygen content is controlled at 240-330ppm.The outlet of holding furnace is communicated with the import of tundish 30, is provided with at least one filter brick in tundish 30, and filter brick number can be 30ppi and 40ppi, in order to filter the impurity in copper liquid. The molten copper in the tundish 30 is introduced into the casting chamber through the outlet of the tundish 30. The casting chamber is enclosed by upper rollers 11, lower rollers 12, and a first block chain 13 and a second block chain 14. After passing through the casting chamber, the molten copper forms a copper ingot. During the casting process, a purge device 20 can clean the first and second block chains 13, 14 in real time or at intervals to remove surface oxides and prevent them from secondary oxidation and entering the ingot. After a period of continuous production, the surfaces of the first and second block chains 13, 14 are polished to remove surface graphite. Furthermore, the copper ingot is introduced into a rolling mill under the action of upper rollers 11 and lower rollers 12. The rolling mill rolls the copper ingot into a copper rod of a predetermined size, such as a diameter of 8±4 mm. Before entering the rolling mill, a milling device is used to remove edges and corners that are prone to impurities and hollowness. The copper rod is then reduced and cooled in a cleaning line, resulting in a copper rod suitable for multi-wire drawing and fine wire production. The solution in the cleaning line can be a mixture of water and isopropyl alcohol, and the concentration of the isopropyl alcohol aqueous solution is 2%-4%, so as to obtain multi-head drawing wire and fine wire copper rod of a certain size.
