Description

Technical Field

[0002] The production process of continuously pouring high-temperature molten steel into ingots with certain cross-sectional shapes and certain dimensions is called continuous steel casting, and the equipment required to complete this process is called a continuous casting complete set of equipment. The electromechanical and hydraulic integration of steel pouring equipment, continuous casting machine main equipment, cutting area equipment, dummy bar collection and conveying equipment constitutes the core equipment of continuous steel casting, which is usually called a continuous casting machine.

[0003] The surfacing roller is one of the important components in the continuous casting machine. When the surfacing roller is in use, it needs to work stably under high temperature and high pressure environment. Therefore, the surfacing roller needs to be cooled during the working process. At present, when the surfacing roller is cooled, the coolant flow is usually used to make the surfacing roller exchange heat. The coolant in the inner cavity of the surfacing roller can be applied to the inner wall of the surfacing roller when the surfacing roller rotates. However, due to the high temperature of the surfacing roller, the coolant attached to the surfacing roller often loses its effect after the surfacing roller rotates a certain angle, which leads to no coolant directly participating in the cooling effect in the second half of the rotation of the surfacing roller, which easily leads to a low cooling effect.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 As shown, a continuous casting machine surfacing roller comprises a surfacing roller 1 for the continuous casting machine, driving members 2 are fixed on both sides of the surface of the surfacing roller 1, the driving members 2 can make the surfacing roller 1 rotate, a liquid inlet pipe 3 is rotatably provided in the inner cavity of the driving member 2 on one side, and a liquid outlet pipe 4 is rotatably provided in the inner cavity of the driving member 2 on the other side, a sealing member 5 is provided at the connection position between the liquid inlet pipe 3 and the driving member 2, and the sealing member 5 is also provided at the connection position between the liquid outlet pipe 4 and the driving member 2, a rotating mechanism 6 is provided in the inner cavity of the liquid inlet pipe 3, and a liquid feeding mechanism 7 is provided on the surface of the rotating mechanism 6. When the surfacing roller 1 is used, the inner cavity of the surfacing roller 1 can have coolant flow through the action of the liquid inlet pipe 3 and the liquid outlet pipe 4, so that the coolant participates in the cooling effect of the surfacing roller 1, and under the action of the rotating mechanism 6, the liquid feeding mechanism 7 in the opposite direction of the rotation direction of the surfacing roller 1 sprays the coolant on the inner cavity of the surfacing roller 1, thereby improving the cooling capacity of the coolant on the surfacing roller 1.

[0021] The rotating mechanism 6 includes a support frame 61 fixed on both sides of the inner cavity of the liquid inlet pipe 3, a rotating rod 62 is rotatably arranged in the inner cavity of the support frame 61, a rotating member 63 is fixed on the surface of the rotating rod 62, one end of the rotating rod 62 passes through the liquid inlet pipe 3, driving rods 64 are fixed on both sides of the surface of the rotating rod 62, a liquid storage shell 65 is fixed on the other end of the driving rod 64, and an orifice 66 is opened on the surface of the liquid storage shell 65. In this embodiment, through the arrangement of the support frame 61, the rotating rod 62, the rotating member 63, the driving rod 64, the liquid storage shell 65 and the orifice 66, when the coolant passes through the inside of the liquid inlet pipe 3, the rotating member 63 is rotated under the impact of the coolant, and then the driving rod 64 drives the liquid storage shell 65 to rotate in the inner cavity of the surfacing roller 1.

[0022] It should be noted that, in the present application, the rotation direction of the rotating member 63 should be opposite to the rotation direction of the surfacing roller 1 .

[0023] The liquid feeding mechanism 7 includes a sealing plate 71 sliding in the inner cavity of the liquid storage shell 65 and a slide groove 73 opened on the surface of the driving rod 64. Connecting rods 72 are fixed on both sides of the surface of the sealing plate 71. The liquid feeding mechanism 7 also includes a driving groove 74 opened on both sides of the inner cavity of the surfacing roller 1. In this embodiment, through the arrangement of the sealing plate 71, the connecting rod 72, the slide groove 73 and the driving groove 74, when the liquid storage shell 65 rotates, the sealing plate 71 fixed to the inner cavity of the liquid storage shell 65 can move the connecting rod 72, and then under the limit of the driving groove 74, the connecting rod 72 is equivalent to the liquid storage shell 65 to be lifted and lowered. Since the sealing plate 71 is fixed to one end of the connecting rod 72, the sealing plate 71 can be lifted and lowered in the inner cavity of the liquid storage shell 65.

[0024] A rotor 8 is rotatably provided on one side of the surface of the connecting rod 72, and the rotor 8 works in contact with the driving groove 74. In this embodiment, the setting of the rotor 8 improves the smoothness of the contact between the connecting rod 72 and the driving groove 74, thereby improving the stability of the liquid feeding mechanism 7 during operation.

[0025] The two side surfaces of the connecting rod 72 are tightly fitted to the surface of the slide groove 73 , and the connecting rod 72 slides on the surface of the slide groove 73 . In this embodiment, through this arrangement, the slide groove 73 can provide a limit for the operation of the connecting rod 72 .

[0026] A plurality of atomizing water spray heads 9 are arranged on the surface of the liquid outlet pipe 4, and the plurality of atomizing water spray heads 9 are evenly spaced and discharged on the surface of the liquid outlet pipe 4. In this embodiment, the coolant inside the liquid inlet pipe 3 can be atomized and sprayed out through the arrangement of the atomizing water spray heads 9, thereby improving the heat absorption effect of the coolant inside the surfacing roller 1.

[0027] Working principle: During the operation of the surfacing roller 1, driven by the driving member 2, the surfacing roller 1 can drive the casting to move. Since the temperature of the casting is relatively high, the temperature of the surfacing roller 1 will also tend to be relatively high. At this time, the staff can use the liquid inlet pipe 3 to provide coolant to the inner cavity of the surfacing roller 1, and under the action of the atomizing water nozzle 9, the coolant is atomized in the inner cavity of the surfacing roller 1 to improve the heat exchange effect. When the coolant passes through the rotating member 63, the rotating member 63 can be rotated, and under the action of the shape of the rotating member 63, the rotation direction of the rotating member 63 is opposite to the rotation direction of the surfacing roller 1.

[0028] Under the continuous infusion of the liquid inlet pipe 3, the coolant rises in the horizontal plane of the inner cavity of the surfacing roller 1, and when the horizontal plane is higher than the working range of the liquid outlet pipe 4, the coolant flows out from the liquid outlet pipe 4, and the heat exchange effect is achieved during the continuous input of the liquid inlet pipe 3 and the continuous output of the liquid outlet pipe 4. When the rotating member 63 causes the driving rod 64 and the liquid storage shell 65 to rotate, under the action of the driving groove 74, the connecting rod 72 drives the sealing plate 71 to rise and fall relative to the liquid storage shell 65. When the liquid storage shell 65 is at the bottom of the surfacing roller 1, under the action of the driving groove 74, the sealing plate 71 is moved away from the orifice 66, and then under the action of the orifice 66, the coolant at the bottom of the inner cavity of the surfacing roller 1 is extracted. When the liquid storage shell 65 rises, under the action of the driving groove 74, the sealing plate 71 is moved close to the orifice 66, and then under the action of the orifice 66, the coolant in the liquid storage shell 65 is sprayed into the inner cavity of the surfacing roller 1, so as to achieve the effect of cooling the inner cavity of the surfacing roller 1.

[0029] When the surfacing roller 1 rotates itself, the coolant in the inner cavity of the surfacing roller 1 can be smeared on the inner wall of the surfacing roller 1. However, since the temperature of the surfacing roller 1 is too high, the coolant cannot support the surfacing roller 1 to complete the rotation and loses its effect. Since the rotation direction of the rotating member 63 is opposite to that of the surfacing roller 1, under the action of the liquid storage shell 65 and the liquid feeding mechanism 7, the coolant can be applied to the other half of the inner cavity of the surfacing roller 1, thereby improving the cooling effect.
