Embodiment 1

[0027] Embodiment one: if figure 1 , figure 2 Shown, the present invention also discloses a kind of manufacturing process of copper rod, comprises the following steps:

[0028] 1) Put the electrolytic copper raw material into a closed mixed molten material furnace for smelting at a melting temperature of 1100-1200°C. After the electrolytic copper is completely melted, continue smelting for 15-20 minutes;

[0029] 2) Transfer the molten material in the closed mixed molten material furnace to the upward continuous casting molten material furnace. The heating temperature of the upward continuous casting molten material furnace is 1080-1100 degrees Celsius; then the molten material enters the continuous casting crystallization through the siphon effect In the continuous casting crystallizer, cooling crystallization is carried out through the cooling water system;

[0030] 3) The crystallized copper rod in the continuous casting crystallizer is drawn out from the top of the cont...

Abstract

The invention discloses a manufacturing process of a copper rod, comprising the following steps: 1) putting electrolytic copper raw materials into a closed mixed melting furnace for smelting, and after the electrolytic copper is completely melted, continue smelting for 15-20 minutes; 2) smelting The molten material in the closed mixed melting furnace is transferred to the upward continuous casting melting furnace, and the heating temperature of the upward continuous casting melting furnace is 1080-1100 degrees Celsius; The copper rod is drawn out from the top of the continuous casting mold, during which oxygen insulation is carried out through the argon thermal insulation device of the continuous casting mold, and the produced copper rod is packaged into rolls. The invention improves the heat insulating effect of the heat insulating sleeve and reduces the energy loss by setting a set of argon circulating flow system.

Description

technical field [0001] The invention relates to the field of copper rod production, in particular to a copper rod manufacturing process. Background technique [0002] In the existing production process of copper rods, there is a heat insulation sleeve outside the bottom of the continuous casting crystallizer, and its heat insulation effect is limited; at the same time, in the existing preparation method, in order to prevent the copper rods from being quenched and oxidized, a separate coating is required on the top of the crystallizer. Install heat preservation device, its energy consumption is serious. Contents of the invention [0003] In view of the above problems, the present invention proposes a copper rod manufacturing process, which solves the defects of limited heat insulation effect of the continuous casting crystallizer in the existing copper rod manufacturing process and serious energy consumption due to separate installation of heat preservation devices. [000...
