Abstract
Description
Technical Field
[0001] The present application relates to the technical field of hot-rolled steel cooling, and in particular to a steel section cooling device. Background Art
[0002] Steel sections are usually used for track laying and are a type of complex cross-section steel. Steel sections are usually prepared by hot rolling, and the end temperature of hot rolling is generally 800-900°C. After hot rolling, the steel sections need to be cooled to facilitate subsequent processing.
[0003] In the related art, water cooling is usually used to cool the steel section. The traditional water cooling method is usually to put the entire section of the steel section into a water cooling tank filled with cold water, and then take out the steel section after the temperature drops.
[0004] Regarding the above-mentioned related technologies, when the steel is placed in the water cooling tank for cooling, the surface temperature of the steel drops rapidly when it enters the water due to the high surface temperature, but the inside is still at a high temperature. At this time, the cooling water around the steel has been heated up, and the cooling speed of the steel is reduced, which prolongs the cooling time. At the same time, the heating of the cooling water causes the inside of the steel to be unable to be cooled in time, resulting in a large temperature difference between the inside and outside of the steel and poor cooling uniformity. Utility Model Content
[0005] In order to improve the uniformity of internal and external cooling of steel sections, the present application provides a steel section cooling device.
[0006] The present application provides a steel section cooling device adopting the following technical solution:
[0007] A steel section cooling device comprises a water inlet pipe, a plurality of water cooling units arranged at intervals and used for cooling the steel section, and a plurality of conveying units arranged staggered with the water cooling units and used for conveying the steel section along the length direction;
[0008] Each of the water cooling units includes a plurality of drainage hoses connected to the water inlet pipe and a spray head arranged on the drainage hose. When the steel section is located in the conveying unit, each of the spray heads is circumferentially arranged at intervals outside the steel section and is aligned with the steel section.
[0009] By adopting the above technical solution, the spray heads are arranged circumferentially around the outside of the steel and aimed at the steel. This layout can ensure that all parts of the steel surface can be evenly sprayed with cooling water. The spray heads are directly aimed at the steel, and the cooling water can directly act on the surface of the steel, quickly reducing the surface temperature of the steel. At the same time, the sprayed cooling water flows continuously, which can continuously take away the heat on the surface of the steel, speeding up the cooling speed of the steel, thereby achieving a uniform reduction in the temperature inside and outside the steel, avoiding the problem of large temperature difference between the inside and outside of the steel and poor cooling uniformity in traditional water cooling methods.
[0010] Furthermore, at least two spray heads are respectively provided on each of the drainage hoses, and the angle range of the spray fan surfaces sprayed by the spray heads is between 45° and 80°.
[0011] By adopting the above technical solution, setting at least two spray heads on each drainage hose can ensure that all parts of the profiled steel can be fully covered by the cooling water. Setting the angle range of the spray fan surface between 45° and 80° can make the spray water more evenly distributed on the surface of the profiled steel, reduce the cooling blind area, and further improve the cooling uniformity. Multiple spray heads working simultaneously can accelerate the flow rate and spraying speed of the cooling water, thereby more quickly reducing the surface temperature of the profiled steel. The appropriate angle range of the spray fan surface can also ensure that the cooling water can fully contact the profiled steel and improve the heat exchange efficiency.
[0012] Furthermore, a track rack for installing the conveying unit is provided above the water inlet pipe. Each of the conveying units includes two conveying rollers that are arranged at an interval up and down and are rotatably connected to the track rack, and the distance between the two conveying rollers is equal to the thickness of the profiled steel.
[0013] By adopting the above technical solution, the track rack provides an installation platform for the conveying rollers. By adjusting the distance between the two upper and lower conveying rollers to be equal to the thickness of the profiled steel, it can ensure that the profiled steel maintains a stable posture during the conveying process, avoiding shaking or offset of the profiled steel in the thickness direction and affecting the cooling effect. This precise conveying method helps to ensure the uniformity and efficiency of the cooling of the profiled steel.
[0014] Furthermore, at least two limiting convex portions are coaxially provided on each of the conveying rollers. The distance between the two limiting convex portions is greater than or equal to the width of the profiled steel. A limiting groove for the profiled steel to be clamped into is jointly formed between the opposite side surfaces of the two limiting convex portions and the outer wall of the conveying roller.
[0015] By adopting the above technical solution, the limiting convex portions are provided on the conveying rollers to form a limiting groove on the conveying rollers. The width of the limiting groove is the same as the width of the profiled steel, so as to fix the profiled steel in the width direction on the conveying rollers, prevent the profiled steel from shaking or offsetting left and right during the conveying process, ensure the uniformity of the cooling effect, and also improve the safety and stability of the conveying process.
[0016] Furthermore, one end of the conveying roller passes through the track rack, and a rotating seat is coaxially provided and fixedly connected to the end of the conveying roller protruding from the track rack.
[0017] By adopting the above technical solution, a rotating seat is provided at the end of the protruding track frame of the conveying roller and is fixedly connected coaxially with the conveying roller. The rotating seat, as an independent component, is convenient for separate disassembly and replacement, making the replacement and maintenance of the conveying roller simpler and faster, reducing the maintenance cost and time. At the same time, the rotating seat is also convenient for connecting with the power source outside the track frame to drive the conveying roller.
[0018] Furthermore, it further includes several driving motors for driving the rotating seat. Define up to six of the conveyor rollers located in the same plane and the corresponding rotating seats as a conveying group, and the number of driving motors corresponds one-to-one with the number of conveying groups;
[0019] A transmission belt is provided between the rotating seats in each conveying group, and the driving motor is electrically connected to the rotating seat at the head / end of the conveying group.
[0020] By adopting the above technical solution, each conveying group is equipped with a driving motor, and all the rotating seats in the group are driven to rotate synchronously through the transmission belt to achieve stable conveying of the profiled steel. The centralized driving method not only simplifies the structure but also improves energy efficiency and reduces energy consumption. The rotating seats at the head and end of the conveying group are directly driven by the driving motor, and the other rotating seats achieve synchronous transmission through the transmission belt. According to the actual needs of the production line, the number and position of the conveying groups can be flexibly configured. Each conveying group is independently driven without interference, and can adapt to the cooling requirements of profiled steel with different lengths and widths.
[0021] Furthermore, a main pipeline and an auxiliary pipeline are respectively communicated with the water inlet pipe, and self-priming pumps are respectively provided on the main pipeline and the auxiliary pipeline.
[0022] By adopting the above technical solution, the main pipeline is responsible for the main cooling water supply, which can ensure that the cooling water can be quickly and evenly supplied to each spray head. The auxiliary pipeline can be used as a backup to provide additional cooling water when needed. The dual-pipeline setting can ensure that when one pipeline fails or needs maintenance, the other pipeline can still work normally, ensuring the continuous operation of the cooling device, improving the stability and reliability of the entire cooling system, and meeting different cooling requirements or coping with emergencies. The two self-priming pumps respectively control the water flow rates of the main pipeline and the auxiliary pipeline, and can adjust the water flow rate according to the actual production situation and cooling requirements to achieve more precise and flexible cooling control.
[0023] Furthermore, a self-cleaning filter is provided on the water inlet pipe.
[0024] By adopting the above technical solution, the self-cleaning filter can effectively filter impurities, particulate matters, etc. in the water entering the cooling system, avoid abrasion or blockage of the spray heads, enable the clean cooling water to better perform heat exchange, reduce the thermal resistance caused by impurities, thereby protecting the normal operation of the entire cooling system and improving the cooling efficiency.
[0025] In summary, the present application includes at least one of the following beneficial technical effects:
[0026] 1. The spray heads are arranged at intervals and staggered with the conveying unit, so that the rail can be continuously sprayed and cooled while being conveyed, improving the cooling efficiency and avoiding the mutual interference between the two actions of spraying and conveying;
[0027] 2. The spray heads are circumferentially wound around the outside of the profiled steel and aligned with the profiled steel to ensure that all parts of the surface of the profiled steel can be evenly sprayed with cooling water, directly acting on the surface of the profiled steel, quickly reducing the surface temperature of the profiled steel. At least two spray heads are arranged on each diversion hose, and the angle range of the spray fan surface is 45° - 80°, which can reduce the cooling blind area and further improve the cooling uniformity;
[0028] 3. Each conveying group is equipped with a driving motor, and all the rotating seats in the group are driven to rotate synchronously through a transmission belt, realizing the stable conveying of the profiled steel, improving the energy efficiency and reducing the energy consumption, flexibly configuring the number and position of the conveying groups, adapting to the cooling requirements of profiled steels with different lengths and widths, and improving the flexibility and scalability of the system;
[0029] 4. The double-pipeline design of the main pipeline and the auxiliary pipeline ensures that when one pipeline fails, the other pipeline can still work normally, guaranteeing the continuous operation of the cooling device. The self-cleaning filter protects the cooling system from the influence of impurities, extends the service life of the equipment, and reduces the maintenance cost. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners
[0038] In order to make the purpose, technical solutions and advantages of the present application clearer and more understandable, the following Figures 1-7 in conjunction with the attached drawings
[0039] and embodiments, the present application will be further described in detail. Figure 1 The embodiment of the present application discloses a section steel cooling device. In this embodiment, words used to express positional relationships such as "upper" and "lower" are all determined with reference to the placement and installation positions of the section steel cooling device in its normal use state. Referring to
[0040] Referring to Figure 2 and Figure 3 a section steel cooling device includes a water inlet pipe 1, a plurality of water cooling units 2 and a plurality of conveying units 3. The water cooling units 2 and the conveying units 3 are both arranged above the water inlet pipe 1 and are spaced apart, and the water cooling units 2 and the conveying units 3 are arranged in a staggered manner. The conveying unit 3 conveys the section steel 0 along the length direction of the section steel 0, and the water cooling unit 2 cools the section steel 0 during the conveying process of the section steel 0.
[0041] Referring to Figure 4 and Figure 5, a single water cooling unit 2 includes a plurality of drainage hoses 21 and spray heads 22. One end of the drainage hose 21 is connected to the water inlet pipe 1. The end of the drainage hose 21 far from the connection with the water inlet pipe 1 is circumferentially wound around the outside of the profiled steel 0. The drainage hose 21 is arranged in a ring shape, and there is a spacing for arranging the spray heads 22 between the annular inner wall and the outer wall of the profiled steel 0. The annular parts of the drainage hoses 21 are arranged adjacent to each other along the length direction of the profiled steel 0. In this embodiment, the number of drainage hoses 21 in each water cooling unit 2 is six, the number of spray heads 22 on each drainage hose 21 is two, and the spray heads 22 are circumferentially arranged at intervals outside the profiled steel 0. The angle range of the spray fan surfaces sprayed by the spray heads 22 is between 45° and 80°. Multiple spray heads 22 work simultaneously to reduce the cooling blind area, so that the cooling water is evenly distributed on the surface of the profiled steel 0 and the cooling uniformity is improved.
[0042] Refer to Figure 6 and Figure 7 , each conveying unit 3 contains two conveying rollers 32 arranged parallel to each other and spaced vertically. Above the water inlet pipe 1, there is an orbital frame 31 for installing the conveying rollers 32. Both conveying rollers 32 are rotatably connected to the orbital frame 31, and the distance between the two conveying rollers 32 is the same as the thickness of the profiled steel 0, so as to form an effect of clamping the profiled steel 0 from above and below. At the middle position of each conveying roller 32, there are two limiting convex parts 33 arranged in a ring and integrally connected. Between the two opposite surfaces of the two limiting convex parts 33 and the conveying roller 32, a limiting groove 331 is formed. The width of the limiting groove 331 is the same as the width of the profiled steel 0, so as to form an effect of limiting the profiled steel 0 from left and right in the limiting groove 331.
[0043] One end of the conveying roller 32 passes through the orbital frame 31. At the end of each conveying roller 32 protruding from the orbital frame 31, a rotating seat 34 is coaxially arranged and fixedly connected. An external drive motor 35 for driving the rotating seat 34 is arranged on the orbital frame 31. Six conveying units 3 are defined as a conveying group, and each conveying group is equipped with a drive motor 35. Each drive motor 35 is electrically connected to the rotating seat 34 at the head or end in each conveying group. A transmission belt 36 is arranged between the rotating seats 34 in the same plane in the same conveying group. In each conveying group, the rotating group directly connected to the drive motor 35 is equivalent to the active rotating seat 34, and the other rotating seats 34 connected by the transmission belt 36 are all driven rotating seats 34, so as to achieve the transmission effect of driving multiple by one in each conveying group. At the same time, the number of rotating seats 34 in the same conveying group is limited to six to avoid the problem of insufficient driving force of the drive motor 35.
[0044] The implementation principle of a section steel cooling device in an embodiment of this application is as follows: The water inlet pipe 1 supplies cooling water to the water cooling unit 2. The water inlet pipe 1 is connected to a main pipeline 11 and an auxiliary pipeline 12. When the main pipeline 11 fails, the auxiliary pipeline 12 can be used as a backup to ensure the continuous supply of cooling water. After the cooling water passes through the main pipeline 11 or the auxiliary pipeline 12, it is filtered by the self-cleaning filter 14 and then supplied to each water cooling unit 2. Each water cooling unit 2 is composed of six drainage hoses 21 and twelve spray heads 22. Each drainage hose 21 surrounds the section steel 0, and each spray head 22 is evenly distributed on the drainage hose 21. The cooling water sprayed by the spray heads 22 covers the surface of the section steel, achieving the effect of cooling the section steel 0. The section steel 0 is conveyed by multiple conveying units 3. Each conveying unit 3 is composed of two parallel conveying rollers 32 arranged at an upper and lower interval. The conveying rollers 32 are connected to the track frame 31 through rotating seats 34 and are driven by a driving motor 35 through a transmission belt 36. The distance between the conveying rollers 32 matches the thickness of the section steel 0, forming an upper and lower clamping effect, and the limiting protrusions 33 on the conveying rollers 32 form a left and right limiting effect, ensuring the stability of the section steel 0 during the conveying process. Through the setting of the driving motor 35 and the transmission belt 36, the linkage between multiple conveying units 3 is realized. The conveying rollers 32 in each conveying group can be driven by the same driving motor 35, improving the conveying efficiency.
[0045] The above are all preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
