[0002] The production process of continuously pouring high-temperature molten steel into ingots with a certain cross-sectional shape and certain size specifications is called continuous steel casting. The equipment required to complete this process is called a continuous casting equipment set. The continuous casting equipment set includes steel casting equipment, continuous casting machine main equipment, cutting equipment, etc. The most core component of the continuous casting machine main equipment is the crystallizer. When in use, molten steel passes through the crystallizer and then solidifies into a solid ingot shell according to the specified cross-sectional shape.

[0029] A number of water inlet holes 3 are formed on the upper wall of the copper tube 1 and are respectively connected to the annular water channel 2;

[0030] External cooling water can enter the annular water channel 2 through the water inlet 3, so that it can evenly cool the outer wall of the copper tube 1;

[0031] A plurality of water outlet holes 4 are formed on the lower wall of the copper tube 1 and are respectively connected to the annular water channel 2;

[0032] The water outlet 4 can facilitate the cooling water in the annular water channel 2 to flow out so as to take away the heat;

[0033] The heat dissipation layer 5 is provided on the outer surface of the copper tube 1;

[0034] The heat dissipation layer 5 is coated on the outer surface of the copper tube 1, and can fully conduct heat to the outer wall of the copper tube 1;

[0035] The first shell 6 is disposed on the upper wall of the copper tube 1 and is located outside the plurality of water inlet holes 3;

[0036] The first shell 6 is fixedly mounted on the upper wall of the copper tube 1 and can be relatively fixed. At the same time, a water inlet is provided on the upper wall of the first shell 6, which can facilitate the staff to add cooling water into the first shell 6 so that the cooling water can flow evenly into the plurality of water inlet holes 3;

[0037] The second housing 7 is disposed on the lower wall of the copper tube 1 and is located outside the plurality of water outlet holes 4;

[0038] The second shell 7 is fixedly mounted on the lower wall of the copper tube 1 and can be relatively fixed. At the same time, a water outlet is provided on the lower wall of the second shell 7. The cooling water in the annular water channel 2 can flow into the second shell 7 through the water outlet 4 and then be discharged through the water outlet, which is convenient for the staff to recycle and reuse.

[0039] The air cooling device is arranged outside the heat dissipation layer 5 and is used for air cooling and heat dissipation of the heat dissipation layer 5 .

[0040] Specifically, the air cooling device includes a pair of fixing frames 8, and the pair of fixing frames 8 are respectively arranged on both sides of the heat dissipation layer 5;

[0041] The outer wall surfaces of the first shell 6 and the second shell 7 are fixedly mounted with a connecting frame 9, and one end of the connecting frame 9 is fixedly connected to the outer surface of the fixing frame 8;

[0042] A pair of slide bars 10 are fixedly installed in the fixed frame 8, and sliders 11 are slidably installed on the outer surfaces of the pair of slide bars 10, and a cooling fan 12 is fixedly installed between the pair of sliders 11;

[0043] The pair of sliders 11 slide on the pair of slide bars 10 respectively, and can drive the heat dissipation fan 12 to move, so that the heat dissipation fan 12 can blow air to the heat dissipation layer 5, and the heat dissipation efficiency of the heat dissipation layer 5 can be improved.

[0044] Specifically, a pair of fixed blocks 13 are fixedly installed on one side wall of the fixed frame 8, a reciprocating screw 14 is rotatably installed between the pair of fixed blocks 13, a reciprocating slider 15 slidably connected to the reciprocating screw 14 is fixedly installed on the outer surface of the cooling fan 12, a driving member 16 is fixedly installed on one end surface of one fixed block 13, and the output end of the driving member 16 is fixedly connected to one end of the reciprocating screw 14;

[0045] The driving member 16 is a motor, and the rotation of its output end can drive the reciprocating screw 14 to rotate. The rotation of the reciprocating screw 14 can drive the reciprocating slider 15 to slide back and forth on its surface. At this time, the reciprocating slider 15 can drive the cooling fan 12 to move, so that it can cool the heat dissipation layer 5 by air.

[0046] Specifically, a water guide block 17 is fixedly installed on the inner wall surface of the annular water channel 2 and below the water inlet hole 3;

[0047] The water guide block 17 is a triangular prism, which can guide the cooling water flowing out of the water inlet hole 3 so that the cooling water can flow evenly to both sides of the annular water channel 2 .

[0048] Specifically, the heat dissipation layer 5 is a high temperature resistant thermal conductive coating.

[0049] Working principle: when in use, the staff fills the external cooling water into the first shell body 6 through the water inlet. At this time, the cooling water flows into the annular water channel 2 through several water inlet holes 3. At this time, the water guide block 17 can guide the cooling water to flow to both sides of the annular water channel 2 to cool the copper tube 1. The cooled cooling water flows into the second shell body 7 through the water outlet hole 4, and then flows out from the water outlet for convenient collection by the staff. At the same time, the heat dissipation layer 5 can conduct heat to the copper tube 1, so that the copper tube 1 accelerates the heat dissipation efficiency. At the same time, the staff starts the heat dissipation fan 12 and the driving member 16. The heat dissipation fan 12 can blow the external wind to the heat dissipation layer 5, which can improve the heat dissipation efficiency of the heat dissipation layer 5. At the same time, the rotation of the output end of the driving member 16 can drive the reciprocating screw 14 to rotate. The rotation of the reciprocating screw 14 can drive the reciprocating slider 15 to slide back and forth, so that it can drive the heat dissipation fan 12 to move, so that the heat dissipation fan 12 can evenly blow the surface of the side wall of the heat dissipation layer 5, so that it can quickly extract the heat in the copper tube 1 and dissipate the heat, bringing convenience to people.
