[0042] The following disclosure provides many different embodiments or examples for implementing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the utility model.

[0043] The embodiments of the utility model will be described in detail below with reference to the drawings. Embodiment 1

[0044] The existing copper rod up-drawing continuous casting crystallizer, the outer side surface of the graphite sizing pipe of the introduction end contacts the flowing water, and the inner side surface contacts the melt, and the melt is cooled and sized by heat exchange with high efficiency heat transfer. However, in the cooling process, the temperature difference of the external flowing water of the graphite sizing pipe in the pulling direction is small, and the temperature difference of the upward metal melt in the graphite sizing pipe in the pulling direction is large, so that the heat exchange efficiency of the graphite sizing pipe in the pulling direction gradually decreases from bottom to top, and the unbalanced heat exchange efficiency increases the crystallization speed difference of the melt from the outside to the inside at different positions, and the copper rod drawing speed in the continuous casting process is not completely uniform, and the time of each section of the copper rod passing through each section of the graphite sizing pipe in the pulling direction is different, thereby affecting the structure and mechanical property uniformity of the metal after forming, and leading to easy copper rod breakage.

[0045] Please refer to Figures 1-5 The embodiment provides a copper rod up-drawing continuous casting crystallizer sizing mechanism for melt cooling and sizing at the introduction end of a copper rod up-drawing continuous casting crystallizer, which can reduce the crystallization speed difference of the melt from the outside to the inside at different positions, thereby improving the structure and mechanical property uniformity of the metal after forming, and reducing the copper rod breakage frequency. The copper rod up-drawing continuous casting crystallizer sizing mechanism mainly comprises an inner tube 100 and a heat transfer assembly 200 arranged outside the inner tube 100.

[0046] The inner tube 100 is used for directly contacting the melt and casting and forming the melt in the process of being pulled upward. Figure 2 , Figure 4As shown in the figure, the inner tube 100 is formed by its body extending from one end to the other end, and its cross section is generally annular. The inner tube 100 mainly consists of an introduction section 110 at one end, a crystallization section 120 in the middle, and a sleeve section 130 at the other end. Among them, the introduction section 110 is used to guide the melt into the inner tube 100, when the crystallizer is working, the introduction section 110 is inserted into the melt with the opening downward, and the melt is pressed into the introduction section 110 under the action of the pressure difference between the inside and outside of the crystallizer, and the outer side of the side wall of the introduction section 110 is provided with an outer flange 112, which is used to be embedded between the shell 500 and the protective sleeve 600 of the crystallizer, and the shaping mechanism is fixed relative to the shell 500 and the protective sleeve 600. The crystallization section 120 is used to carry out the process of metal melt from liquid phase to solid phase, when the crystallizer is working, the outer side of the crystallization section 120 is the cooling liquid in the crystallizer, and the inner side is the metal melt, and the crystallization section 120 carries out efficient heat transfer and conduction. In this embodiment, the inner diameter of the crystallization section 120 is smaller than that of the introduction section 110, so that there is a margin when the melt in the introduction section 110 flows and fills into the crystallization section 120, so that when the drawing speed is fast in the drawing process, the melt below is not enough to fill in time, and the copper rod can be avoided. Defects such as necking or broken line caused by the melt not filling the crystallization section 120 in time. And, the outer side of the side wall of the crystallization section 120 is provided with a plurality of first annular grooves 122, the body of each first annular groove 122 is semicircular concave, the first annular groove 122 is formed by its body extending along the circumference of the side wall of the crystallization section 120, and a plurality of first annular grooves 122 are arranged in sequence on the outer side of the side wall of the crystallization section 120 along the axial direction of the crystallization section 120. At the same time, the sleeve section 130 is arranged at the other end of the inner tube 100 opposite to the introduction section 110, the inner diameter of the sleeve section 130 is larger than that of the crystallization section 120, and the sleeve section 130 is arranged on the upper wire guide pipe 300, so that the shaping mechanism of the embodiment is connected with the wire guide pipe 300, and the copper rod continues to cool down along the wire guide pipe 300 and is drawn out.

[0047] The heat transfer assembly 200 is also formed by the body extending from one end to the other end, and the cross section is substantially annular, the heat transfer assembly 200 is sleeved outside the crystallization section 120 of the inner tube 100, for enhancing the stability of the inner tube 100, and conducting heat between the crystallization section 120 and the cooling liquid outside. In the embodiment, the heat transfer assembly 200 adopts copper-iron alloy material, and the inner tube 100 adopts graphite material, therefore, the thermal conductivity of the heat transfer assembly 200 is lower than the thermal conductivity of the inner tube 100, which reduces the thermal conductivity of the entire side wall of the shaping mechanism, and the solidification rate of the outer layer of the copper rod during solidification is reduced more, and the solidification rate of the inner layer is reduced less, thereby reducing the solidification rate difference between the inner layer and the outer layer, making the crystal organization of the internal radial growth of the copper rod more uniform, which can enhance the strength of the copper rod, and prevent the problem of separation between the inner and outer layers of the copper rod caused by the segmentation of the copper rod. And, a plurality of inner flanges 202 are arranged on the inner side of the side wall of the heat transfer assembly 200, the body of each inner flange 202 is a semicircular protrusion, the inner flange 202 is formed by the body extending along the circumference of the side wall of the heat transfer assembly 200, and the plurality of inner flanges 202 are arranged in sequence along the axial direction of the heat transfer assembly 200 on the inner side of the side wall of the heat transfer assembly 200. When the inner tube 100 and the heat transfer assembly 200 are assembled, the plurality of inner flanges 202 inside the heat transfer assembly 200 are embedded in the plurality of first annular grooves 122 outside the inner tube 100, and are shape-fitted with each other, thereby separating the outer wall of the crystallization section 120 and the cooling liquid outside, and enhancing the structural strength of the shaping mechanism. At the same time, from one end close to the introduction section 110 to the other end, the size of the plurality of inner flanges 202 and the plurality of first annular grooves 122 gradually decreases, that is, the cross-sectional area in the circumferential direction gradually decreases, so that the thickness of the graphite layer with higher thermal conductivity of the side wall of the shaping mechanism gradually increases, and the thickness of the pure copper layer with lower thermal conductivity gradually decreases, thereby the thermal conductivity of the side wall of the shaping mechanism gradually increases from one end close to the introduction section 110 to the other end. When the crystallizer is in continuous casting operation, the temperature difference of the flowing water outside the graphite shaping tube in the traction direction is small, the temperature difference of the rising metal melt inside the graphite shaping tube in the traction direction is large, and the thermal conductivity of the side wall of the shaping mechanism gradually increases from one end close to the introduction section 110 to the other end, so that the heat exchange efficiency of the graphite shaping tube in the traction direction tends to be uniform and stable from bottom to top, the uniform and stable heat exchange efficiency reduces the difference in crystallization speed of the melt from outside to inside at different positions, thereby making the structure and mechanical properties of the metal after forming more uniform, which can reduce the frequency of copper rod breakage.

[0048] In summary, in the present embodiment, the copper rod is provided with an inner tube 100 and a heat transfer assembly 200 sleeved outside the inner tube 100. The heat transfer assembly 200 is combined by a first heat transfer component 210 and a second heat transfer component 220. The first heat transfer component 210 and the second heat transfer component 220 are the left and right parts of the heat transfer assembly 200 divided along the center line of the bottom end face. The cross sections of the first heat transfer component 210 and the second heat transfer component 220 are both semicircular annular. When the first heat transfer component 210 and the second heat transfer component 220 are combined, the end faces of the heat transfer assembly 200 are respectively spliced to form a second annular groove 203 and a third annular groove 204. The second annular groove 203 and the third annular groove 204 extend along the circumference of the heat transfer assembly 200. The first fixed ring 230 and the second fixed ring 240 are respectively embedded in the second annular groove 203 and the third annular groove 204 during installation, so as to form a stable overall structure of the heat transfer assembly 200. The first heat transfer component 210 and the second heat transfer component 220 are combined with the first fixed ring 230 and the second fixed ring 240, so that the heat transfer assembly 200 can be conveniently installed on the inner tube 100. The circumferential cross sections of the first fixed ring 230 and the second fixed ring 240 are isosceles trapeziums, and the circumferential cross sections of the second annular groove 203 and the third annular groove 204 adapted to the first fixed ring 230 and the second fixed ring 240 are also isosceles trapeziums. The bottom sides of the trapeziums are arranged towards the outside of the heat transfer assembly 200, so that the first fixed ring 230 and the second fixed ring 240 are more firmly installed and have better fixing effect.

[0049] As shown in Figure 3 , Figure 5 the heat transfer assembly 200 in the present embodiment is mainly combined by a first heat transfer component 210 and a second heat transfer component 220. The first heat transfer component 210 and the second heat transfer component 220 are the left and right parts of the heat transfer assembly 200 divided along the center line of the bottom end face. The cross sections of the first heat transfer component 210 and the second heat transfer component 220 are both semicircular annular. When the first heat transfer component 210 and the second heat transfer component 220 are combined, the end faces of the heat transfer assembly 200 are respectively spliced to form a second annular groove 203 and a third annular groove 204. The second annular groove 203 and the third annular groove 204 extend along the circumference of the heat transfer assembly 200. The first fixed ring 230 and the second fixed ring 240 are respectively embedded in the second annular groove 203 and the third annular groove 204 during installation, so as to form a stable overall structure of the heat transfer assembly 200. The first heat transfer component 210 and the second heat transfer component 220 are combined with the first fixed ring 230 and the second fixed ring 240, so that the heat transfer assembly 200 can be conveniently installed on the inner tube 100. The circumferential cross sections of the first fixed ring 230 and the second fixed ring 240 are isosceles trapeziums, and the circumferential cross sections of the second annular groove 203 and the third annular groove 204 adapted to the first fixed ring 230 and the second fixed ring 240 are also isosceles trapeziums. The bottom sides of the trapeziums are arranged towards the outside of the heat transfer assembly 200, so that the first fixed ring 230 and the second fixed ring 240 are more firmly installed and have better fixing effect.

[0050] It should be pointed out that the heat transfer assembly 200 in the present embodiment can also be made of brass, copper-aluminum alloy, copper-titanium alloy and the like. The condition to be met is that the thermal conductivity of the material used for the heat transfer assembly 200 is lower than that of the material used for the inner tube 100. Embodiment 2
