Description

Technical Field

[0001] This utility model relates to the field of copper strip production technology, and in particular to a dumbbell-shaped chute. Background Technology

[0002] Currently, the casting machines used in the semi-continuous casting process of copper strip smelting workshops employ integral narrow chute sluices. Adding alloys during casting leads to slag formation. If the slag doesn't float in the chute, it can easily be carried into the ingot, causing inclusions. This results in peeling during later processing, severely impacting product quality. Therefore, to effectively solve the slag formation problem during casting, this design proposes a dumbbell-shaped chute. Summary of the Invention

[0003] The present invention aims to provide a dumbbell-shaped chute.

[0004] A dumbbell-shaped chute includes: a shell and an outlet, wherein the shell has a cuboid structure, the chute is provided inside the shell, the chute has a dumbbell shape, and an outlet is provided at one end of the chute.

[0005] Preferably, the chute includes: an end chute and a middle chute, the middle chute having a long strip structure, and end chutes having a square structure at both ends of the middle chute.

[0006] Preferably, the end groove is wider than the middle groove.

[0007] The beneficial effects of the above scheme are:

[0008] 1. The process and supporting equipment of this utility model are simple. By improving the shape of the chute, the problem of copper slag not being able to float and causing slag inclusions in the crystallizer can be effectively solved. Attached Figure Description

[0009] Figure 1 This is a schematic diagram of the structure of this utility model;

[0010] In the diagram: 1. Shell; 2. End groove; 3. Middle groove; 4. Outlet. Detailed Implementation

[0011] The present invention will be further described clearly and completely below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0012] according to Figure 1 As shown, a dumbbell-shaped chute includes: a shell 1 and an outlet 4, wherein the shell 1 has a cuboid structure, the shell 1 has a chute inside, the chute has a dumbbell-shaped structure, and one end of the chute has an outlet 4.

[0013] Specifically, the chute comprises end slots 2 and middle slots 3, the middle slots 3 are in a long strip structure, and the two ends of the middle slots 3 are provided with the end slots 2, and the end slots 2 are in a square structure.

[0014] Specifically, the end slots 2 are wider than the middle slots 3.

[0015] In the working process, compared with the original casting mold, firstly, the end slots 2 have a larger area, and when the copper liquid is poured, the copper liquid will stay in the end slots for a certain time, at this time, the slag in the runner can have a certain time and space to float in the copper liquid, the copper liquid will flow to the middle slots 3, and then flow to the other end of the end slots 2, at this time, the copper liquid still has time to stay and further float the slag in the copper liquid, and finally the copper liquid flows out through the outlet 4, because the slag in the copper liquid floats in the end slots 2 for a certain time, it ensures that the copper liquid flowing out from the outlet has a reduced slag content, and the slag will not be brought into the crystallizer, avoiding the inclusion of slag after casting.
