Description

Technical Field

[0001] The utility model belongs to the technical field of cooling devices, and particularly relates to a cooling device for processing rollers of a segment of a continuous casting machine. Background Art

[0002] Continuous casting is essentially a process of continuously injecting molten metal into a mold, forming a solidified shell with a certain strength and then pulling out the casting blank. The segment is one of the key equipment in the continuous casting process. It supports and guides the shell with a liquid core through upper and lower pinch rolls, pulls and straightens the casting blank, and further accelerates the solidification of the casting blank by means of the direct cooling of secondary cooling water and the indirect cooling of the cooling water of the segment. The quality of the segment of the continuous casting machine directly affects the quality of the casting blank, the drawing speed of the casting machine and the operation rate of the casting machine, etc., and plays a very important role in continuous casting production and quality.

[0003] The segment of the continuous casting machine requires cooling the high-temperature slab by vertically arranging cooling nozzles between the segment rollers. However, due to the slab transmission covering the segment rollers and resulting in insufficient cooling of the segment rollers themselves, there is a problem of deformation and damage of the segment rollers under the long-term high-temperature conduction of the high-temperature slab. In order to cool the segment rollers, arranging a water spraying cooling system is relatively cumbersome, and due to the shielding of the segment rollers by the slab transmission and transportation, the arrangement is difficult. In addition, the direct method of continuously spraying water for cooling has the disadvantage of large water consumption. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a cooling device for processing rollers of a segment of a continuous casting machine to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A cooling device for processing rollers of a segment of a continuous casting machine, including a fixed bracket. A water storage and cooling mechanism is arranged at the lower part of the fixed bracket. The water storage and cooling mechanism includes a bottomless receiving box, a lifting water spraying box and an electric push rod. The bottomless receiving box is fixed at the lower port of the fixed bracket. The lifting water spraying box is arranged inside the bottomless receiving box. The electric push rod is arranged below the lifting water spraying box. The surface of the lifting water spraying box is provided with water spraying nozzles. A water passing hose with a stop valve is arranged at the lower end of the lifting water spraying box.

[0006] It should be noted in the solution that the inside of the lifting water spraying box is hollow, and the water passing hose is communicated with the inner cavity of the lifting water spraying box.

[0007] Furthermore, it is worth noting that the water spraying nozzles are evenly distributed on the upper end surface of the lifting water spraying box, and the water spraying nozzles are communicated with the inner cavity of the lifting water spraying box.

[0009] As a preferred implementation manner, a sealing rubber ring is fixed to the side surface of the lifting and spraying box, and the sealing rubber ring is attached to the inner wall of the bottomless receiving box.

[0010] As a preferred implementation manner, a water storage chamber is provided inside the bottomless receiving box, and the lifting and spraying box is arranged directly below the roll of the continuous casting machine segment.

After the cooling water cools the segment roll, it automatically falls back and is collected in the water storage chamber of the bottomless receiving box. In this way, the bottomless receiving box can synchronously collect the cooling water during the water storage process for reuse.

[0015] (2) By providing the water storage and cooling mechanism, after the bottomless receiving box is filled with water, it is introduced into the roll rack of the continuous casting machine segment through the immersion roll docking port to soak and cool the high-temperature segment roll.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] See also Figure 1-4 The utility model provides a cooling device for processing the sector rollers of a continuous casting machine, comprising a fixed bracket 1. A water storage cooling mechanism is provided at the lower part of the fixed bracket 1. The water storage cooling mechanism comprises a bottomless receiving box 3, a lifting water spray box 7 and an electric push rod 11. The bottomless receiving box 3 is fixed at the lower port of the fixed bracket 1. The lifting water spray box 7 is arranged inside the bottomless receiving box 3. The electric push rod 11 is arranged below the lifting water spray box 7. A water spray nozzle 8 is provided on the surface of the lifting water spray box 7. A water hose 9 with a shut-off valve is provided at the lower end of the lifting water spray box 7.

[0024] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth explaining in detail that the interior of the lifting water spray box 7 is hollow, and the water hose 9 is connected to the inner cavity of the lifting water spray box 7.

[0025] Further as Figure 3 As shown, it is worth noting that the water nozzles 8 are evenly distributed on the upper end surface of the lifting water spray box 7, and the water nozzles 8 are connected to the inner cavity of the lifting water spray box 7.

[0026] This solution has the following working process: Before use, the fixed bracket 1 is fixedly connected to the frame outside the segment roll of the continuous caster, so that the frame of the segment roll of the continuous caster, the fixed bracket 1, the bottomless receiving box 3 and the lifting base 4 form a cooling water tank. At the same time, the lifting spray box 7 is connected to the high-pressure water flow through the water pipe 9 below. When in use, the lifting spray box 7 is suspended below the segment roll in the raised state of the electric push rod 11. The cooling water introduced into the lifting spray box 7 is sprayed onto the segment roll through the spray nozzles 8 for cooling from above. After the cooling water cools the segment roll, it automatically falls back and is collected in the water storage chamber 6 of the bottomless receiving box 3. In this way, the bottomless receiving box 3 can collect the cooling water synchronously during the water storage process for reuse.

[0027] According to the above working process, it can be known that: the lifting spray box 7 is suspended below the segment roll in the raised state of the electric push rod 11. The cooling water introduced into the lifting spray box 7 is sprayed onto the segment roll through the spray nozzles 8 for cooling from above. After the cooling water cools the segment roll, it automatically falls back and is collected in the water storage chamber 6 of the bottomless receiving box 3. In this way, the bottomless receiving box 3 can collect the cooling water synchronously during the water storage process for reuse.

[0028] Furthermore, as shown in Figure 1 、 Figure 2 and Figure 4 it is worth specifically stating that the lower port of the bottomless receiving box 3 is fixed with a lifting base 4, and the surface of the lifting base 4 is provided with a telescopic sliding opening. The water pipe 9 is arranged in the telescopic sliding opening of the lifting base 4.

[0029] Furthermore, as shown in Figure 4 it is worth specifically stating that a sealing rubber ring 10 is fixed on the side of the lifting spray box 7, and the sealing rubber ring 10 is attached to the inner wall of the bottomless receiving box 3.

[0030] Furthermore, as shown in Figure 1 it is worth specifically stating that a water storage chamber 6 is arranged inside the bottomless receiving box 3, and the lifting spray box 7 is arranged directly below the segment roll of the continuous caster. During the process of continuously filling the bottomless receiving box 3 with water, the lifting spray box 7 descends along the bottomless receiving box 3, so as to expand the water storage space of the bottomless receiving box 3. After the bottomless receiving box 3 is filled, it is introduced into the frame of the segment roll of the continuous caster through the immersion roll docking port 12 for soaking and cooling the high-temperature segment roll. The way of continuous contact with the cooling water is conducive to improving the cooling effect of the segment roll. When the water temperature drops due to high-temperature evaporation during the water storage inside the bottomless receiving box 3, the electric push rod 11 can be used to control the lifting spray box 7 to lift upward along the bottomless receiving box 3, so as to adjust the water storage height to maintain the soaking and cooling work of the segment roll.

[0031] Furthermore, as shown in Figure 1As shown, it is worth explaining in detail that the sleeve housing of the electric push rod 11 is fixed to the bottom of the lifting base 4, and the output shaft of the electric push rod 11 passes through the lifting base 4 and is fixed to the bottom of the lifting water spray box 7.

[0032] Further as Figure 1 As shown, it is worth mentioning that a support frame 5 is fixed to the lower end surface of the raised base 4, a fixing hole 2 is provided on the upper surface of the fixed bracket 1, the fixed bracket 1 is fixed to the lower end of the sector roller frame of the continuous casting machine, and a dipping roller docking port 12 is provided at the upper end of the fixed bracket 1.

[0033] In summary: the lifting water spray box 7 is suspended in the lower position of the fan-shaped roller when the electric push rod 11 is raised. The cooling water entering the lifting water spray box 7 is sprayed on the fan-shaped roller from above through the water nozzle 8 for cooling treatment. After the cooling water cools the fan-shaped roller, it automatically falls back and is collected in the water storage chamber 6 of the bottomless receiving box 3. In this way, the bottomless receiving box 3 can synchronously collect cooling water for reuse during the water storage process; after the bottomless receiving box 3 is full, it is passed into the fan-shaped segment roller frame of the continuous casting machine through the immersion roller interface 12 and the high-temperature fan-shaped roller is immersed and cooled. The continuous contact with cooling water is beneficial to improving the cooling effect of the fan-shaped roller. When the water temperature drops due to high-temperature evaporation in the bottomless receiving box 3, the water storage height can be adjusted to maintain the immersion and cooling of the fan-shaped roller.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
