The invention will be described in further detail with reference to the following detailed description and accompanying drawings:
in the crystallizer of the oxygen-free copper up-drawing method in the prior art, pure copper is directly cooled when a copper rod is produced. This results in the copper rod cooling faster on the outside than on the inside, resulting in the copper rod being concave upward on the inside, as shown in fig. 4. Through the up-drawing crystallizer in the prior art, the produced copper rod can cause the line fluctuation of the internal crystalline structure to be larger, and the structure of the copper rod is slightly weakened. Simultaneously, solidify the in-process of going out the copper pole, because outside solidification rate is faster than inside solidification rate greatly, can lead to the copper pole outside to solidify and inside but not solidify yet, inside not yet solidified part can lead to the problem that drops under the effect of gravity.
Referring to fig. 1 to 3, in the present embodiment, an up-drawing crystallizer includes a graphite mold 10 having a first channel 9 therein, and a pipe assembly for cooling the graphite mold 10. The crystallizer also comprises a heat dissipation part 8 which is sleeved or attached on the outer wall of the ink mould, and the heat conductivity of the heat dissipation part 8 is lower than that of copper. Specifically, when the copper liquid subassembly solidifies into the copper pole at the inside first passageway 9 of graphite jig 10, because the thermal conductivity of heat dissipation piece 8 is less than the copper, consequently can reduce the outer solidification rate of copper pole, let the inside and outer solidification rate difference of copper pole diminish, let the inside brilliant texture of copper pole comparatively mild, the structural strength of the copper pole of reinforcing production. Meanwhile, the problem that the inner part of the copper rod falls off because the outer layer of the copper rod is solidified and the inner part of the copper rod is not completely solidified can be prevented; namely: the utility model discloses a crystallizer can prevent the inside problem that drops at the solidification process of copper pole. In fig. 1 and 2, the solution a is liquid copper. In this embodiment, the crystallizer further comprises a graphite sheath 6 sleeved on the outermost layer.
As shown in fig. 1 and 2, in the present embodiment, the piping assembly includes an inner pipe 5, a middle pipe 4 fitted around the inner pipe 5, and an outer pipe 3 fitted around the middle pipe 4. Wherein, an inner channel and an outer channel are respectively formed between the inner tube 5 and the middle tube 4 and between the middle tube 4 and the outer tube 3, and the inner channel is communicated with the outer channel. In addition, the pipe assembly is provided with a water inlet 1 and a water outlet, and the water inlet 1 and the water outlet are respectively communicated with the inner passage and the outer passage. In this embodiment, the inner and outer channels, which constitute the cooling channel 7 for the medium to flow through, are in direct contact with the heat sink 8, and good heat transfer can take place.
In the present embodiment, the medium flowing through the cooling passage 7 is water. Water enters the inner channel from the water inlet 1 and then flows to the water outlet from the inner channel through the outer channel, and the water inlet 1 and the water outlet are communicated through equipment such as a pump and the like to form a circulation loop.
In the present embodiment, the heat sink 8 includes a first heat sink layer that is nested or attached to an outer wall of the ink mold, and a second heat sink layer that is nested or attached to the first heat sink layer, and has a thermal conductivity lower than that of the first heat sink layer. The first heat dissipation layer is made of copper, and the second heat dissipation layer is made of copper-iron alloy. The heat conductivity of the copper-iron alloy is lower than that of copper, so that the cooling rate of the outer layer of the copper rod can be greatly reduced. In another embodiment, the second heat dissipation layer may be copper aluminum, copper tin, or copper titanium alloy.
In the practical application process, due to different calibers of the first channels 9 in the graphite mold 10, the diameters of the produced copper rods are different, so that the difference value of the heat dissipation rates of the outer layer and the inner part of the copper rods is different, and therefore, second heat dissipation layers with different heat conductivities are required to be adopted, and the practical requirements of the crystallizer are guaranteed. Specifically, the thermal conductivity required for the second heat dissipation layer, and the material can be obtained through multiple experiments, which are not described herein again.
In another embodiment, the heat dissipation element 8 may directly use cupper-iron, copper-aluminum, copper-tin, or copper-titanium alloy. The thermal conductivity of these alloys is also less than that of copper, and can also achieve a reduction in the rate of heat dissipation from the outer layer of the copper rod.
Through the above-mentioned scheme of this embodiment, the crystallizer of present case can let the copper pole of producing, and the line of its inside crystalline structure is more even, strengthens the structural strength of copper pole. Meanwhile, the problem that the inside of the copper rod falls off in the solidification process can be prevented. Has good practicability and production value.
