Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chute structures, in particular to a molten copper chute structure. Background Art
[0002] In the production of copper rod continuous casting and rolling production lines, there are often some quality defects in copper rods. For example, after the cross-section is enlarged for inspection, there are phenomena such as slag inclusions, pores or uneven texture in the cross-section of the copper rod. After research and tracing, it is found that the main reasons for the problems are that when putting copper into the chute before copper continuous casting, the slag in the copper is not completely removed, and the magnesium-based substances and high-aluminum-based substances precipitated or peeled off from the refractory of the chute cause slag, which directly affects the quality of the copper rod.
[0003] Therefore, many manufacturers will set slag blocking and filtering bricks in the chute. Although it has the effect of filtering residues, in actual work, the residues accumulated at the front end of the slag blocking and filtering bricks are very easy to block the flow of molten copper, and it is necessary to frequently clean and replace the slag blocking and filtering bricks, which will cause the suspension of work and affect production; moreover, the slag blocking and filtering bricks will cause a flow resistance phenomenon to the flow of molten copper, resulting in a long flow time of molten copper, and then leading to accelerated cooling, which is not conducive to the smooth flow of molten copper. Moreover, the low-temperature environment promotes the enrichment of residues in molten copper, resulting in an increase in the copper content and volume of residues, which is not conducive to copper production. Content of the Utility Model
[0004] The purpose of the utility model is to provide a molten copper chute structure to solve the problems of frequent cleaning and replacement of slag blocking and filtering bricks, resulting in work suspension, and the slag blocking and filtering bricks will cause a flow resistance phenomenon to the flow of molten copper, both of which affect copper production.
[0005] To solve the above technical problems, the utility model adopts the following technical solutions:
[0006] A molten copper chute structure includes a chute body. A flow dividing block is arranged in the flow channel of the chute body. The flow dividing block divides the flow channel into two branch flow channels.

[0007] A chute cover is arranged above the chute body. A heating device is arranged on the chute cover. The heating end of the heating device faces the branch flow channels.
[0008] A further technical solution is that the heating end of the heating device is located on the feeding side of the slag blocking brick.
[0009] A further technical solution is that the heating device is a fuel gas burner, and the nozzle of the fuel gas burner faces the branch flow channels.
[0010] A further technical solution is that the two sides of the flow blocking brick and the inner side of the branch flow channel are arc-shaped structures that are mutually adapted.
[0011] A further technical solution is that at least one installation groove is provided on the slag baffle brick, and a filter grille is slidably installed in the installation groove.
[0012] A further technical solution is that the flow baffle brick, the slag baffle brick and the filter grille are all made of refractory materials.
[0013] A further technical solution is that a liquid outlet is provided at the confluence of the two branch channels.
[0014] Compared with the prior art, at least one of the following beneficial effects can be achieved by the present utility model:

[0025] Embodiment 1:
[0026] As shown in this embodiment Figure 1 and Figure 2 a copper liquid chute structure includes a chute body 1. A flow dividing block 2 is arranged in the flow channel of the chute body 1. The flow dividing block 2 divides the flow channel into two branch flow channels 3. A flow blocking brick 4 and a slag blocking brick 5 are detachably installed in the branch flow channels 3 in sequence along the advancing direction of the copper liquid. A chute cover 6 is arranged above the chute body 1. A heating device is arranged on the chute cover 6, and the heating end of the heating device faces the branch flow channel 3.
[0027] The copper liquid is put into the chute, which is called copper discharging. One side of the chute serves as a conveying function, while the other side facilitates the filtration of the copper liquid for slag skimming. The copper liquid enters the flow channel of the chute body 1 and can enter two branch channels 3 through the diversion of the diversion block 2. Generally, one of the branch channels 3 is selected for circulation, and the other branch channel 3 is blocked by the flow blocking brick 4 to achieve the effect of the two branch channels 3 working in cooperation. The two branch channels 3 are used alternately, one in standby and one in operation, overcoming the drawback of needing to stop the copper discharging operation during the operation. The copper liquid is filtered by the slag blocking brick 5, and the residue accumulates at the front end of the slag blocking brick 5 for slag skimming treatment. The relatively pure copper liquid flows away and enters the next process; the filtration of the slag blocking brick 5 will cause resistance to the flow of the copper liquid, and the heating equipment can supply heat in time to prevent the temperature of the copper liquid from dropping and ensure the fluidity of the copper liquid.
[0028] Preferably, the heating end of the heating equipment is located on the feeding side of the slag blocking brick 5.
[0029] Due to the accumulation of residue and the slag blocking brick 5 itself at the front end of the slag blocking brick 5, the flow rate of the copper liquid is extremely slow and the liquid level is relatively high, making it easy to cool down. The heating equipment can supply heat in time to prevent the temperature of the copper liquid from dropping and ensure the fluidity of the copper liquid; and the high temperature can reduce the enrichment and solidification of the copper liquid on the residue, effectively avoiding the reduction of the copper liquid.
[0030] Preferably, the heating equipment is an oil and gas burner, and the burner nozzle 9 of the oil and gas burner faces the branch channel 3.
[0031] The flame of the oil and gas burner is stable. Gas is preferably used, which is clean and environmentally friendly. It mainly heats the branch channel 3, reduces the heating area, lowers the energy consumption, and saves costs and energy while ensuring the fluidity of the copper liquid.
[0032] Preferably, the two sides of the flow blocking brick 4 and the inner side of the branch channel 3 are arc-shaped structures that are mutually adapted.
[0033] The arc of the flow blocking brick 4 is convex outward, and the arc of the branch channel 3 is concave inward. On the premise of achieving a detachable effect through sliding fit, the convex arc can reduce the accommodation corners for the copper liquid. Otherwise, once it cools and solidifies, it is very difficult to clean, which will affect the installation of the flow blocking brick.
[0034] The slag blocking brick 5 and the branch channel 3 can also be of the above structure.
[0035] Preferably, at least one installation groove is provided on the slag blocking brick 5, and a filter grille 7 is slidably installed in the installation groove.
[0036] The filter grille 7 is convenient for disassembly, and the precision specifications are optional, facilitating timely replacement.
[0037] Preferably, the flow blocking brick 4, the slag blocking brick 5, and the filter grille 7 are all made of refractory materials.
[0038] Made of refractory materials, it has the effect of withstanding high temperatures.
[0039] Preferably, a liquid outlet 8 is provided at the confluence of the two branch channels 3.
[0040] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
