[0023] The chute structure for copper rod production includes an upper trough body 1 and a lower trough body 2 stacked up and down, and the upper trough body 1 and the lower trough body 2 are elongated structures made of castable materials. The cross section is roughly rectangular. figure 1 It is a three-dimensional schematic view of the lower tank body representing an embodiment of the present invention, such as figure 1 As shown, the lower tank body is a strip-shaped structure with a roughly rectangular cross-section, and a channel for the copper liquid to flow is provided on its upper surface.

[0024] The copper rod production chute structure that the first embodiment of the present invention relates to is as follows: figure 2 shown. figure 2 It shows the structure of the chute for copper rod production which concerns on the 1st Example of this invention.

[0037] image 3 is a cross-sectional view showing the structure of the chute for copper rod production according to the second embodiment of the embodiment of the present invention. The structure of the chute involved in the second embodiment is mostly the same as the structure of the chute in the first embodiment, and the description of the same structure is omitted here, and the structure different from the first embodiment is emphasized.

[0038] like image 3 As shown, the two side surfaces of the casting body 20 of the lower tank body part 2 are in the form of inclination to the outside, specifically, the cross section of the casting body 2 20 is an inverted trapezoidal structure. Correspondingly, the heat insulation board 25 and the third pouring body 26 have slopes that fit the two side surfaces of the second pouring body 20, so that the surface of the material has a compacting effect and the materials can be combined more closely.

Abstract

The invention provides a chute structure used for copper rod production and a copper rod manufacturing method. The chute structure comprises an upper chute body and a lower chute body, wherein the upper chute body comprises an upper shell in a box iron shape with a downward opening, and the inner wall of the upper shell is sequentially provided with ceramic paper, a nano microhole heat insulation plate, a ceramic fiber plate and a first casting body; and the lower chute body comprises a lower shell in a box iron shape with an upward opening, and the inner wall of the lower shell is sequentially provided with ceramic paper, a nano microhole heat insulation plate, a ceramic fiber plate and a second casting body. A channel for allowing melted copper to flow is arranged on the upper surface of the second casting body, the upper chute body and the lower chute body are attached tightly through the upper shell and the lower shell, and the heat preservation performance of the chute structure is good, so that energy loss is small, and the service life is longer; mounting is fast, maintenance is easy and the maintenance cost is low; and since the heat insulation performance is good, the temperature of the outer surface of a chute is lowered, and accidental injuries to personnel is avoided.

Description

technical field [0001] The invention relates to the field of copper rod manufacturing, in particular to a copper rod production chute structure and a copper rod manufacturing method using the chute structure. Background technique [0002] In the dip-coating copper rod production process, the electrolytic copper is preheated in the preheating furnace to burn off the attachments on the surface of the copper plate, and then enters the melting furnace to melt into copper liquid, and then enters the holding furnace through the chute. The chute is mainly composed of shell, pouring material and burner; the main function of the chute is to make the natural gas and air premixed in the chute to burn, to produce CO, CO2 and other components, to reduce and keep the copper liquid flowing into the chute, and to avoid the oxidation of the copper liquid . During the production process, the heat insulation effect of the chute is poor, and the temperature of the chute shell is high, which ca...
