Description

Technical Field

[0001] This application relates to the field of water-cooled box technology, and in particular to a staged temperature-controlled water-cooled box. Background Technology

[0002] High-speed wire rod rolling lines are typically designed with air cooling systems to cool the wire rod. Different steel grades require different cooling temperatures and times, and the original air cooling system generally meets the rolling requirements. However, when rolling certain special steel grades, the slow cooling rate and difficulty in accurately controlling the cooling temperature make it difficult to meet the rolling process requirements. Therefore, a water-cooling system is needed for high-speed wire rod rolling.

[0003] Patent CN219724115U discloses a water cooling device for high-speed wire rod rolling. This prior art uses a filter plate to filter the spray water used for water cooling, and then starts a centrifugal motor in conjunction with a stirring shaft to stir the collected water source. The centrifugal force generated by stirring causes the water source to come into contact with a bag filter to filter out dust particles. Then, through the cooperation of a water pump and a circulating water pipe, the water is transported to the inside of the water tank for recycling, thereby improving the efficiency of the device.

[0004] However, the aforementioned existing technologies have the following technical defects:

[0005] First, in this existing technology, all spray pipes have the same aperture, and spraying with a fixed aperture will increase the ineffective water consumption. At the same time, the water cooling device has multiple sets of spray pipes, which can cool multiple steel wires at the same time. However, the number of spray pipes cannot be reasonably adjusted according to the number of steel wires. If a small number of steel wires are cooled, all spray pipes will still work at the same time, which will also increase the ineffective water consumption and cause serious waste of water resources in the device.

[0006] Second, in this existing technology, water cooling of the steel wire results in unevenly distributed water accumulation on the surface of the steel wire after removal. This water accelerates local oxidation of the steel wire and absorbs heat during evaporation, causing a sudden drop in local temperature of the steel wire. This leads to uneven temperature distribution in different parts of the steel wire, thus affecting the quality of the finished steel wire product.

[0007] In summary, existing technologies still have room for improvement in terms of water conservation and the quality of finished steel wire products. Therefore, those skilled in the art have proposed a device for adjusting the number of nozzles according to the number of steel wires and for timely dewatering of water-cooled steel wires. Summary of the Invention

[0008] To address the aforementioned problems, this application provides a staged temperature-controlled water-cooled box, employing the following technical solution:

[0009] It includes a cooling box, on the inner top surface of which are installed multiple evenly distributed baffles. Multiple evenly distributed inlets are provided on the front side of the cooling box, and an outlet aligned with each inlet is provided on one side of the rear side of the cooling box.

[0010] The system includes a spraying mechanism, which includes an electric cylinder mounted on the upper side of the cooling box. Inside the cooling box, there is a set of horizontally distributed tubes on the front side of each partition, with both ends rotatably connected to the inner wall of the cooling box. A set of downward-facing nozzles are installed on the side of the horizontal tubes. The orifice diameter of the nozzles on each set of horizontal tubes decreases sequentially from the inlet to the outlet. A water-blocking piston connected to the electric cylinder is slidably installed inside the horizontal tube.

[0011] It also includes a water removal mechanism, which consists of multiple annular tubes located inside the cooling box near the tail end. Multiple evenly distributed jet nozzles are installed on the sides of the annular tubes, and a set of annularly distributed brushes is also provided in front of each set of jet nozzles.

[0012] Preferably, a rectangular plate is installed on the inner wall of the cooling box between the brush and the jet nozzle. Each group of brushes is mounted on the outer side of a mounting cylinder that is rotatably connected to the rectangular plate. The side of the rectangular plate has a through hole aligned with each mounting cylinder.

[0013] Preferably, an arc-shaped groove is provided on the outer side of the mounting cylinder, and a slider adapted to it is slidably arranged in the arc-shaped groove.

[0014] Preferably, a strip groove is provided on the side of the cooling box, and a mounting bracket connected to all the sliders is slidably arranged in the strip groove.

[0015] Preferably, a multi-port pipe connected to all annular pipes is provided below the annular pipe, and an air pump connected to one end of the multi-port pipe is installed on the side of the cooling box. An air-blocking piston connected to an electric cylinder is slidably arranged inside the multi-port pipe.

[0016] Preferably, the side of the cooling box with the strip groove is also provided with a drive mechanism, which slides back and forth in the strip groove using a drive mounting bracket.

[0017] Preferably, one end of the horizontal tube in the same group extends to the outside of the cooling box and is equipped with a gear. On one side of the cooling box, a rack that meshes with each gear is slidably provided. All racks are equipped with a sliding plate whose end is bent downward and connected to the part of the mounting bracket that extends to the outside of the cooling box.

[0018] Preferably, a speed measuring instrument is installed on the front side of the cooling box above the edge inlet, and a diversion pipe connected to all the horizontal pipes is installed on the upper side of the cooling box, with a flow control valve installed on the diversion pipe.

[0019] Preferably, a support roller is rotatably installed between the inner walls of the cooling box below each partition, a tail roller is rotatably installed between the inner walls of the cooling box near the rear side, and a controller is installed on the other side of the cooling box.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. The spray mechanism in this application has nozzles on each group of horizontal pipes with decreasing orifice diameters from inlet to outlet. First, multiple large-diameter nozzles in the first three zones spray water for rapid cooling, and then small-diameter nozzles in the last two zones spray water for precise temperature control. Compared with nozzles of uniform orifice diameter, this reduces water consumption. At the same time, each horizontal pipe is equipped with a movable water-blocking piston, which can be adjusted according to the number of steel wires to be cooled to open the corresponding number of nozzles, avoiding a large amount of water consumption when cooling a small number of steel wires, thus saving water resources.

[0022] Second, this application utilizes a dewatering mechanism to remove surface water from steel wires after water cooling. This mechanism employs a combination of brushes and air nozzles for cleaning. The brushes remove most of the accumulated water, and any remaining water is broken down into smaller droplets by the brush bristles, reducing the difficulty of subsequent air-jet dewatering, improving dewatering efficiency, reducing steel wire drying time, directly increasing production line speed, and preventing water accumulation on the steel wire surface that could lead to temperature differences and thermal stress concentration, affecting the quality of the finished steel wire. Furthermore, the driving mechanism allows the brushes to rotate back and forth at the same angle, ensuring complete cleaning of the steel wire surface. This avoids the problem of water being squeezed into the gaps between the brush bristles and remaining in a fixed contact area, which is common with fixed brushes.

[0023] Third, when used in conjunction with a spraying mechanism, the spraying nozzles can swing back and forth at the same angle to spray, which not only expands the spraying coverage area and reduces the cooling blind zone of the steel wire, but is also particularly suitable for high-speed rolled steel wire. At the same time, the swinging spray can change the water flow angle, allowing the water flow to impact the surface of the steel wire at different angles, thereby improving heat transfer efficiency.

[0036] The following combination Figure 1 - Figure 10 The embodiments of this application will be described in detail.

[0037] This application discloses a staged temperature-controlled water-cooled box with a spray mechanism. The nozzle diameters on each group of horizontal tubes decrease sequentially from the inlet to the outlet. First, multiple large-diameter nozzles in the first three zones spray water for rapid cooling. Then, small-diameter nozzles in the last two zones spray water for precise temperature control. Compared with nozzles of uniform diameter, this reduces water consumption. In addition, each horizontal tube is equipped with a movable water-blocking piston. The position of the water-blocking piston can be adjusted according to the number of steel wires to be cooled, allowing the corresponding number of nozzles to open. This avoids excessive water consumption when cooling a small number of steel wires, thus saving water resources.

[0038] Example 1:

[0039] like Figure 1 and Figure 3 As shown, the cooling box 1 includes a cooling box 1. Multiple evenly distributed partitions 5 are installed on the inner top surface of the cooling box 1. The partitions 5 divide the inner top of the cooling box 1 into multiple areas. Multiple evenly distributed inlets 6 are provided on the front side of the cooling box 1. An outlet 7 aligned with each inlet 6 is provided on one side of the rear side of the cooling box 1. A drain pipe 8 is installed on the side of the cooling box 1 near the bottom. The inlets 6 are used for steel wires to enter the interior of the cooling box 1 and to be removed from the outlet 7 after cooling. The drain pipe 8 is used to drain water from the interior of the cooling box 1.

[0040] like Figure 3 As shown, support rollers 9 are rotatably installed between the inner walls of the cooling box 1 below each partition 5, and tail rollers 21 are rotatably installed between the inner walls of the cooling box 1 near the rear side. All support rollers 9 and tail rollers 21 provide support for the steel wire entering the cooling box 1, and the rotatable connection also facilitates the advancement of the steel wire in the cooling box 1.

[0041] like Figure 1 , Figure 4 and Figure 5 As shown, the system includes a spraying mechanism 2, which includes an electric cylinder 206 mounted on the upper side of the cooling box 1. Inside the cooling box 1, a set of horizontally distributed pipes 201 are provided on the front side of each partition 5. The two ends of the horizontal pipes 201 are rotatably connected to the inner wall of the cooling box 1. A set of downward-facing nozzles 202 are installed on the side of each inlet 6 of the horizontal pipes 201. The orifice diameter of the nozzles 202 on each set of horizontal pipes 201 decreases sequentially from the inlet 6 to the outlet 7. After the steel wire enters, it is first cooled quickly by spraying water with multiple large-diameter nozzles 202 in the first three zones, and then the temperature is precisely controlled by spraying water with small-diameter nozzles 202 in the last two zones.

[0042] like Figure 1 and Figure 4 As shown, a branch pipe 215 connected to all horizontal pipes 201 is installed on the upper side of the cooling box 1. The branch pipe 215 is connected to a water source to supply water to each horizontal pipe 201.

[0043] like Figure 1 and Figure 2 As shown, a speed measuring instrument 11 is installed on the front side of the cooling box 1 above the edge inlet 6, and a flow control valve 12 is installed on the diversion pipe 215. A controller 18 is installed on the other side of the cooling box 1. The controller 18 is electrically connected to the speed measuring instrument 11 and the flow control valve 12. The speed measuring instrument 11 detects the rolling speed of the incoming steel wire and then sends a signal to the controller 18. The controller 18 controls the flow control valve 12 to adjust the water flow rate of the diversion pipe 215, so as to realize the linear adjustment of water volume with rolling speed and reduce water consumption.

[0044] The relationship between rolling speed and flow rate is: Q = 0.02v^2 + 1.5v (Q is the flow rate in L / min, V is the rolling speed in m / s). After receiving the rolling speed, the controller 18 calculates the flow rate and controls the flow control valve 12 to execute.

[0045] like Figure 4 and Figure 6 As shown, the connection between the diverter pipe 215 and the horizontal pipe 201 is located above the first set of nozzles 202. A water-blocking piston 203 is slidably disposed inside the horizontal pipe 201 between the first set of nozzles 202 and the second set of nozzles 202. When the water-blocking piston 203 is between the first set of nozzles 202 and the second set of nozzles 202, water can only be sprayed out from the first set of nozzles 202. When it is between the second and third sets, water can only be sprayed out from the first set of horizontal pipes 201 and the second set of horizontal pipes 201, and so on. By adjusting the position of the water-blocking piston 203, the position of which set of horizontal pipes 201 sprays water is controlled.

[0046] The corresponding nozzle 202 can spray water according to the number and position of the steel wires entering, avoiding water waste caused by the nozzle 202 that is far away from the steel wires. For a single steel wire, the inlet 6 closest to the speed measuring instrument 11 is preferred to be used. For multiple wires, water is used sequentially from the inlet 6 closest to the speed measuring instrument 11 to the right.

[0047] like Figure 4 and Figure 6 As shown, a crossbar 204 extending to the outside of the cooling box 1 is installed on the center of the side of the water-blocking piston 203. All the ends of the crossbars 204 are connected to the strip plate 205 connected to the electric cylinder 206. The ends of the crossbars 204 and the strip plate 205 are rotatably connected. The extension and retraction of the electric cylinder 206 drives all the water-blocking pistons 203 to move through the strip plate 205 and the crossbars 204, so that one electric cylinder 206 can control the number of water sprayed by the nozzles 202 on all the horizontal pipes 201.

[0048] like Figure 1 and Figure 2 As shown, two slide rails 13 are symmetrically installed on the upper side of the cooling box 1. Each slide rail 13 has a sliding seat 14. An L-shaped frame 15 connected to the strip plate 205 is installed on the upper side of the slide seat 14. The moving strip plate 205 drives the slide seat 14 to move on the slide rail 13 through the L-shaped frame 15, which enhances the stability of the strip plate 205 when it moves. The surface of the slide rail 13 is coated with a smooth layer to ensure that the slide seat 14 slides on it without jamming.

[0049] like Figure 1 and Figure 2As shown, multiple evenly distributed infrared generators 16 are installed on one side of one of the slides 14 on the upper side of the cooling box 1. Infrared receivers 17 adapted to the infrared generators 16 are installed on the side of the slides 14. At the same time, the positions of all infrared generators 16 in the group are adapted to the positions of multiple sets of nozzles 202 on the horizontal tube 201. When the infrared receiver 17 is aligned with the first infrared generator 16, the first set of nozzles 202 is opened. When it is aligned with the second infrared generator 16, the first and second sets of nozzles 202 are opened, and so on. Thus, the horizontal tube 201 is opened according to the number of inlets 6 used, and the set of nozzles 202 corresponding to the used inlet 6 is opened.

[0050] like Figure 2 As shown, the controller 18 is electrically connected to the infrared generator 16, the infrared receiver 17, and the electric cylinder 206. The operator turns on the corresponding infrared generator 16 by opening several sets of nozzles 202 on the horizontal pipe 201. Then, when the electric cylinder 206 works, it drives the strip plate 205 to move, which in turn drives the water-blocking piston 203 to move the slide 14, which in turn drives the infrared receiver 17 to move. When the infrared receiver 17 receives the infrared rays emitted by the working infrared generator 16, it sends a signal to the controller 18, and the controller 18 controls the electric cylinder 206 to turn off.

[0051] In summary, the infrared generator 16 at the corresponding position is opened according to the required number of steel wires to be cooled. Then, the electric cylinder 206 extends, moving all the water-blocking pistons 203, and simultaneously moving the infrared receiver 17. When the infrared receiver 17 aligns with the working infrared generator 16, the electric cylinder 206 closes, and the number of nozzles 202 opened is adjusted. Multiple steel wires are then sequentially fed into the cooling box 1 from the left inlet 6 to the right, ensuring that all steel wires roll at the same speed. Water enters the horizontal pipe 201 through the diversion pipe 215, and then... The nozzle 202 sprays water to cool the steel wire. After the steel wire enters, it is first cooled quickly by spraying water from multiple large-diameter nozzles 202 in the first three zones. Then, it is precisely controlled by spraying water from small-diameter nozzles 202 in the last two zones. The cooled water is discharged through the drain pipe 8. After the steel wire is cooled, it is removed from the outlet 7. The rolling speed of the steel wire is detected by the speed measuring instrument 11 and sent to the controller 18. After receiving the rolling speed, the controller 18 calculates the flow rate and controls the flow control valve 12 to control the water flow rate in the diversion pipe 215.

[0052] like Figure 3 and Figure 7As shown, it also includes a dewatering mechanism 3, which includes a set of annular pipes 301 located inside the cooling box 1 near the tail end. All annular pipes 301 are distributed front to back and aligned with the corresponding outlets 7. Multiple evenly distributed jet nozzles 302 are installed on the side of the annular pipes 301 and are inclined towards the inlet 6. The cooled steel wire passes through each set of two annular pipes 301. The annularly distributed jet nozzles 302 blow away the residual water stains on the surface of the steel wire, reducing the drying time of the steel wire, speeding up the work efficiency, and also avoiding the accumulation of water on the surface of the steel wire, which can cause temperature differences and thermal stress concentration.

[0053] At the same time, the jet nozzle 302 sprays air at an inclined angle, forming a shearing airflow, which is more effective at stripping water from the surface of the steel wire than vertical jetting.

[0054] like Figure 3 and Figure 7 As shown, a multi-port pipe 303 connected to all annular pipes 301 is provided below the annular pipe 301. An air pump 304 connected to one end of the multi-port pipe 303 is installed on the side of the cooling box 1. Air is injected into the multi-port pipe 303 by the air pump 304. The gas enters each annular pipe 301 and is ejected from each jet nozzle 302.

[0055] like Figure 7 and Figure 8 As shown, each group of air nozzles 302 is also provided with a group of ring-shaped brushes 307 on the front side. A rectangular plate 305 is installed between the brushes 307 and the air nozzles 302 on the inner wall of the cooling box 1. Each group of brushes 307 is installed with a mounting cylinder 306 that is rotatably connected to the rectangular plate 305 on the outer side. The side of the rectangular plate 305 has a through hole 311 aligned with each mounting cylinder 306. After the steel wire is cooled by the spray mechanism 2, it passes through the aligned brushes 307, through holes 311 and ring tube 301 in sequence. The bristles of the brushes 307 are made of high-temperature resistant ceramic fiber. The brushes 307 are used to brush away most of the water on the surface of the steel wire, and then the air nozzles 302 are used to blow away the remaining water. The combination of the two methods improves the water removal effect on the surface of the steel wire.

[0056] It should be noted that the surface of the mounting cylinder 306 is also provided with multiple drainage holes (not shown in the figure). The drainage holes allow the water brushed off to drain quickly out of the mounting cylinder 306. At the same time, the obstruction of the rectangular plate 305 also prevents the air nozzle 302 from blowing a large amount of water onto the brush 307.

[0057] like Figure 7As shown, an arc-shaped groove 308 is provided on the outer side of the mounting cylinder 306, and a matching slider 309 is slidably arranged in the arc-shaped groove 308. A strip groove 20 is provided on the side of the cooling box 1, and a mounting bracket 310 connected to all sliders 309 is slidably arranged in the strip groove 20. When the mounting bracket 310 slides back and forth in the strip groove 20, it drives each slider 309 to move back and forth. The sliding sliders 309 moving back and forth drive the mounting cylinder 306 to deflect back and forth at the same angle through the arc-shaped groove 309 on the surface of the mounting cylinder 306. This can completely clean the surface of the steel wire and avoid the problem that the water in the fixed contact area between the brush and the steel wire is easily squeezed into the gap between the brush bristles, forming most of the residue.

[0058] like Figure 1 and Figure 10 As shown, the side of the cooling box 1 with the strip groove 20 is also provided with a drive mechanism 4. The drive mechanism includes an L-shaped seat 401 installed on the side of the cooling box 1. A motor 402 is installed on the side of the L-shaped seat 401. A turntable 403 is installed on the drive end of the motor 402. A drive rod 404 with its end hinged to the mounting frame 310 is rotatably installed on the side edge of the turntable 403. The running motor 402 drives the turntable 403 to rotate. The rotating turntable 403 drives the mounting frame 310 to reciprocate through the drive rod 404.

[0059] like Figure 7 and Figure 9 As shown, a baffle piston 313 is slidably disposed inside the multi-pass pipe 303 between the first group of annular pipes 301 and the second group of annular pipes 301. An L-shaped rod 314 extending to the outside of the cooling box 1 and bent upward to connect with the strip plate 205 is installed on the side of the baffle piston 313. The baffle piston 313 can control the number of annular pipes 301 opened on the multi-pass pipe 303, ensuring that the group of jet nozzles 302 corresponding to the unused outlet 7 does not spray. At the same time, the movement of the baffle piston 313 is driven by the strip plate 205, so that when each group of nozzles 202 is opened, its corresponding jet nozzle 302 is also opened.

[0060] In summary, the running motor 402 drives the turntable 403 to rotate. The rotating turntable 403 drives the mounting frame 310 to reciprocate through the drive rod 404. After being cooled by the spray mechanism 2, the steel wire passes through the aligned brushes 307, through holes 311 and annular tubes 301. The brushes 307 brush away most of the water on the surface of the steel wire, and then the air nozzles 302 blow away the remaining water. At the same time, when the mounting frame 310 slides back and forth in the strip groove 20, it drives each slider 309 to move back and forth. The sliding sliders 309 move back and forth and drive the mounting cylinder 306 to deflect back and forth at the same angle through the arc-shaped groove 309 on the surface of the mounting cylinder 306. This can completely clean the surface of the steel wire and avoid the problem that when the contact area between the fixed brush and the steel wire is unchanged, the water is easily squeezed into the gap between the brush bristles and forms most of the residue.

[0061] like Figure 1 and Figure 4 As shown, one end of the horizontal tube 201 extends to the outside of the cooling box 1 and is equipped with a gear 207. On one side of the cooling box 1, a rack 208 is slidably arranged on one side of each gear 207 and meshes with it. The reciprocating rack 208 drives the horizontal tube 201 to reciprocate through the gear 207. Then, during the water spraying process of the nozzle 202, the horizontal tube 201 is deflected by the deflection. The oscillating water spray of the nozzle 202 can expand the coverage area and reduce the cooling blind zone of the steel wire, which is especially suitable for high-speed rolled steel wire. At the same time, the oscillating water spray can change the water flow angle, allowing the water flow to impact the surface of the steel wire at different angles, thereby improving the heat transfer efficiency.

[0062] Such as 1 and Figure 10 As shown, all racks 208 are mounted on the lower side with a sliding plate 209 whose end bends downward and connects to the part of the mounting bracket 310 that extends to the outside of the cooling box 1. When the drive mechanism 4 drives the mounting bracket 310 to move back and forth, it also drives the sliding plate 209 connected to it to move back and forth. The sliding plate 209 moving back and forth drives all racks 208 to move back and forth.

[0063] Example 2:

[0064] Based on Example 1, such as Figure 1 As shown, an auxiliary roller 10 is rotatably installed below each set of horizontal tubes 201 inside the cooling box 1. The end of the auxiliary roller 10 and the gear 207 on the same side extends to the outside of the cooling box 1 and is rotatably installed with an L-shaped seat 19 connected to the side of the cooling box 1. A rocker arm 210 is installed at the center of the side of the gear 207 at the end of the middle horizontal tube 201 of each set. A striking wheel 211 is rotatably installed at the lower end of the rocker arm 210. The auxiliary roller 10 can also support the steel wire moving forward in the cooling box 1. At the same time, during the reciprocating deflection of the gear 207, it will also drive the rocker arm 210 to reciprocate. The reciprocating deflection of the rocker arm 210 will drive the striking wheel 211 to strike the adjacent auxiliary roller 10, causing it to vibrate. Then, the vibration is transmitted to the supported steel wire, causing the steel wire to vibrate slightly. The vibration can allow the surface of the steel wire to come into full contact with the cooling water during the cooling process, improving the cooling efficiency and reducing the local accumulation of cooling water on the surface of the steel wire.

[0065] This application also discloses a method for using a staged temperature-controlled water-cooled box, the steps of which are as follows:

[0066] S1. Pre-adjustment: Adjust the position of the water-blocking piston 203 in advance according to the number of steel wires to be cooled. Specifically, open the infrared generator 16 at the corresponding position according to the number of steel wires to be cooled. Then, the electric cylinder 206 extends to move all the water-blocking pistons 203 and move the infrared receiver 17 at the same time. When the infrared receiver 17 is aligned with the working infrared generator 16, the electric cylinder 206 is closed. At this time, the position adjustment of the water-blocking piston 203 is completed, so that all the nozzles 202 on the left side of the water-blocking piston 203 are opened, and then the set of nozzles 202 on each horizontal pipe 201 corresponding to the inlet 6 to be used is opened. At the same time, the moving strip plate 205 will also move the air-blocking piston 313 to the predetermined position and open all the annular pipes 301 on the left side of the air-blocking piston 313.

[0067] S2. Steel wire cooling: The rolled steel wires are inserted into the cooling box 1 from left to right and cooled by the spray mechanism 2. Specifically, multiple steel wires are fed into the cooling box 1 from the left inlet 6 to the right to ensure that all steel wires have the same rolling speed. Water enters the horizontal pipe 201 through the diversion pipe 215 and is then sprayed out by the open nozzles 202 to cool the steel wires. After the steel wires enter, they are first sprayed with water by multiple large-diameter nozzles 202 in the first three zones for rapid cooling. Then, they are sprayed with water by small-diameter nozzles 202 in the last two zones for precise temperature control. The cooled water is discharged through the drain pipe 8, and the cooled steel wires are removed from the outlet 7.

[0068] S3. Surface dehydration: The dehydration mechanism 3, in conjunction with the drive mechanism 4, removes water from the surface of the cooled steel wire. Specifically, the running motor 402 drives the turntable 403 to rotate. The rotating turntable 403 drives the mounting frame 310 to reciprocate through the drive rod 404. After being cooled by the spray mechanism 2, the steel wire passes through the aligned brushes 307, through holes 311, and annular tube 301. The brushes 307 brush away most of the water on the surface of the steel wire, and then the air nozzles 302 blow away the remaining water. At the same time, when the mounting frame 310 slides back and forth in the strip groove 20, it drives each slider 309 to move back and forth. The sliding sliders 309 move back and forth through the arc-shaped grooves 309 on the surface of the mounting cylinder 306, causing the mounting cylinder 306 to deflect back and forth at the same angle, which can completely clean the surface of the steel wire.

[0069] S4. The oscillating and reciprocating mounting bracket 310 drives all horizontal tubes 201 to deflect back and forth, causing all nozzles 202 to deflect back and forth. Specifically, when the drive mechanism 4 drives the mounting bracket 310 to move back and forth, it also drives the slide plate 209 connected to it to move back and forth. The reciprocating slide plate 209 drives all racks 208 to move back and forth, and through the gear 207, it drives the horizontal tubes 201 to deflect back and forth. In turn, during the water spraying process of the nozzles 202, the deflected horizontal tubes 201 drive the nozzles 202 to deflect. The oscillating water spraying of the nozzles 202 can expand the coverage area and reduce the cooling blind zone of the steel wire, which is especially suitable for high-speed rolled steel wire. At the same time, the oscillating water spraying can change the water flow angle, allowing the water flow to impact the surface of the steel wire at different angles, thereby improving the heat transfer efficiency.
