Description

Technical Field

[0001] This utility model relates to the field of annealing furnace production technology, and in particular to an annealing furnace strip cooling device. Background Technology

[0002] In the metallurgical industry, strip steel is a common processed product. The stainless steel cold-rolled precision strip bright annealing production line is mainly used for the continuous bright annealing of thin stainless steel strips. The production line mainly consists of an uncoiler, a bright furnace inlet looper, a bright annealing furnace, a bright furnace outlet looper, a coiler, and other equipment. It is also equipped with an ammonia decomposition station and a hydrogen recovery unit. The bright annealing furnace consists of inlet and outlet sealing rollers, a furnace body, a muffle furnace, and cooling fans. Heat is generated by burning natural gas inside the furnace, and this heat is transferred to the muffle furnace to heat the thin stainless steel strip, thus achieving the purpose of heat treatment.

[0003] During production, especially when producing steel strips of a certain thickness (e.g., 0.5 mm or less), strip breakage accidents occur frequently. When a breakage occurs inside the furnace, handling it is quite difficult. There are two main challenges: First, during production, the furnace is filled with reducing gas and under positive pressure (typically 1.1 kPa) by the input of a mixture of hydrogen and nitrogen. Once a breakage occurs, the hydrogen in the furnace must be completely replaced with nitrogen before a safe handling of the breakage is possible. Second, the furnace temperature during annealing can reach as high as 1100 degrees Celsius. After a breakage occurs, the strip remaining in the furnace is extremely hot, posing a significant safety threat to the sealing rollers, rubber rollers, and workers during the annealing process.

[0004] Currently, when handling strip breakage inside the furnace, the high-temperature strip steel remaining in the furnace first needs to be pulled out of the annealing furnace using tension rollers, with one end pulled towards the exit side and the other towards the entrance side. During the pulling process, because the cooling fan needs to be shut down, the temperature of the strip head when it comes out of the annealing furnace reaches as high as 300 degrees Celsius, which can easily damage the sealing rollers and rubber rollers at the entrance and exit, and also poses a risk of burns to workers. At this time, workers need to use a wet mop to cool the strip steel, and the mop needs to be sprayed with water continuously to prevent damage to related equipment and facilities and burns to workers due to insufficient cooling. After the strip head is pulled out, a steel wire rope that is normally placed in the furnace needs to be used to pull the strip steel from the entrance side through the furnace to the exit side for welding. During this process, the steel wire rope or strip steel also needs to be cooled continuously. Currently, the traditional manual cooling method is inefficient and poses safety hazards, easily causing burns to workers.

[0005] Therefore, improving the efficiency and safety of cooling operations for broken belts is an urgent problem that needs to be solved. Utility Model Content

[0006] The purpose of this utility model is to provide a strip-breaking cooling device for annealing furnaces. This strip-breaking cooling device is used for strip-breaking cooling in heating furnaces. The device is simple and reliable to operate, and effectively improves operational safety and cooling efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An annealing furnace strip cooling device, comprising:

[0009] A water tank, the top side of which forms an opening, the water tank having side walls surrounding the periphery and a bottom wall located at the bottom;

[0010] Two arc-shaped hanging plates are respectively disposed on two opposite side walls around the water tank. The center lines of the arcs of the two arc-shaped hanging plates are arranged parallel. Each arc-shaped hanging plate has a first side and a second side in its arc-shaped extension direction. The first side is connected to the top of the corresponding side wall, and the second side forms a free end. The arc-shaped protrusions of the arc-shaped hanging plates face the opening away from the bottom of the water tank. The arc-shaped hanging plates are used to hang on the support rollers.

[0011] A first water spray pipe is installed inside the water tank. The axis of the first water spray pipe is parallel to the axis of the arc of the arc-shaped hanging plate. The first water spray pipe is located in the water tank near one of the arc-shaped hanging plates. The first water spray pipe has multiple first water spray nozzles, which are used to spray water onto the broken strip located in the water tank. Two first limiting blocks are provided in the middle of the first water spray pipe. The two first limiting blocks are spaced apart along the extension direction of the axis of the first water spray pipe. The first limiting blocks have second water spray nozzles that are connected to the first water spray pipe. The water spray coverage of the second water spray nozzles covers at least the gap between the two first limiting blocks. The gap between the two first limiting blocks is used for the passage of the wire rope.

[0012] Water supply equipment, the water supply equipment being used to supply water to the first spray pipe;

[0013] A guide roller, the axis of which is parallel to the axis of the first water spray pipe, is rotatably mounted in the water tank around its own axis. The guide roller is located on the side of the first water spray pipe facing the other arc-shaped hanging plate and is spaced apart from the first water spray pipe. The distance between the guide roller and the plane containing the opening is greater than the distance between the first water spray pipe and the plane.

[0014] The aforementioned annealing furnace strip breakage cooling device can be kept on standby in the factory when there is no strip breakage. It can be temporarily installed and used when a strip breakage occurs inside the furnace. Specifically, when using this device to cool the broken strip, the water tank can be placed on the outlet side of the annealing furnace. Since there is a sealing roller at the outlet of the annealing furnace, this roller can be reused as a support roller. For ease of explanation, the arc-shaped hanging plate near the first water spray pipe in the water tank is called the first arc-shaped hanging plate, and the other arc-shaped hanging plate is called the second arc-shaped hanging plate. During installation, the first arc-shaped hanging plate is hung on the sealing roller, covering its upper side. The second arc-shaped hanging plate can be hung on a roller (e.g., a transfer roller) on the production line near the annealing furnace, which also serves as a support roller. Thus, the water tank is fixedly installed on the outlet side of the annealing furnace. Because it is hung on the support rollers on both sides, it can be removed simply by lifting it upwards. This device is simple and reliable to install and disassemble, and very convenient to use.

[0015] After installation, the broken strip is pulled out of the furnace using a steel wire rope. The steel wire rope pulls the broken strip, which passes over the upper surface of the first arc-shaped hanging plate. The first arc-shaped hanging plate hangs on the sealing roller, providing some protection to prevent the sealing roller from being damaged by heat. Then, the broken strip is pulled to the water tank. The steel wire rope passes under the first water spray pipe and between the two first limiting blocks. Cooling water sprayed from the second water spray nozzle cools the steel wire rope, and the two first limiting blocks restrict the steel wire rope from passing through the middle, preventing it from deviating during its forward movement. When the broken strip passes under the first water spray pipe, the first… The spray nozzles spray cooling water towards the broken belt to cool it down. Then, the steel wire rope pulls the broken belt through the bottom of the guide roller and finally out above the second arc-shaped hanging plate. Thus, the water tank is placed on the conveyor path that the broken belt passes through after it is pulled out. The broken belt can be continuously cooled as it passes through the water tank. Because the guide roller is lower than the first spray pipe and the second arc-shaped hanging plate, the broken belt is recessed at the guide roller, which facilitates the cooling water to flow down and collect at the bottom of the water tank. This prevents the cooling water from flowing onto the ground with the steel belt and protects the surrounding equipment and environment.

[0016] Therefore, the above-mentioned strip cooling device for annealing furnaces is used for strip cooling in heating furnaces, reducing manual labor. It only requires pulling the strip into a water tank to achieve cooling water spraying and cooling. The operation is simple and reliable, and it can also accurately cool the wire rope. There is no need for manual cooling of the strip or wire rope, which effectively improves the safety of operation, reduces the risk of burns to workers, and achieves continuous cooling by water spraying during the pulling process, which effectively improves the efficiency of cooling operations.

The second water spray pipe is installed in the water tank and is located on the side of the guide roller away from the first water spray pipe, and is spaced apart from the guide roller. The distance between the guide roller and the plane relative to the plane where the opening is located is greater than the distance between the second water spray pipe and the plane. The second water spray pipe is provided with a plurality of third water spray nozzles, which are used to spray water onto the strip broken in the water tank.

[0034] refer to Figure 1 and Figure 3 As shown, this embodiment of the present invention provides a cooling device for annealing furnace strip breakage. For ease of explanation, the direction from the bottom of the water tank 1 to the open side is considered vertically upward, and the plane perpendicular to the vertical direction is considered horizontally. Specifically, the cooling device for annealing furnace strip breakage provided in this embodiment includes: a water tank 1, an arc-shaped hanging plate 2, a first water spray pipe 3, a water supply device, and a guide roller 5; wherein, the water tank 1 has a side wall surrounding the periphery and a bottom wall located on the bottom side, and the top side of the water tank 1 forms an open side. For example, the water tank 1 can be formed by a box body, and the top side of the box body is an open structure, constituting the open side of the top side of the water tank 1; two arc-shaped hanging plates 2 are provided, and the two arc-shaped hanging plates 2 are arranged at intervals along the first direction, and the two arc-shaped hanging plates 2 are respectively provided on two opposite side walls around the periphery of the water tank 1. The center lines of the arcs of the two arc-shaped hanging plates 2 are arranged parallel, and each arc-shaped hanging plate 2 extends in its arc direction. The device has a first side and a second side facing upwards. The first side is connected to the top of the corresponding sidewall, and the second side forms a free end. The arc-shaped protrusion of the arc-shaped hanging plate 2 faces away from the bottom of the water tank 1 from the opening, and the arc-shaped concave part of the arc-shaped hanging plate 2 faces downwards. The arc-shaped hanging plate 2 is used to hang on the support roller. For example, the arc-shaped hanging plate 2 is a circular arc-shaped hanging plate 2, and the curvature of the arc-shaped hanging plate 2 is adapted to the support roller, so that it can better match and adhere to the support roller, and the hanging is more secure. In addition, the central angle of the arc of the arc of the arc of the hanging plate 2 is 160° to 190°. The specific central angle of the arc of the arc of the hanging plate 2 can be selected as 170°, 175°, 180° or 185°.

[0035] The first water spray pipe 3 is installed inside the water tank 1. The axis of the first water spray pipe 3 is parallel to the axis of the arc of the arc-shaped hanging plate 2. In the horizontal direction, the first water spray pipe 3 is located in the water tank 1 near one of the arc-shaped hanging plates 2. In the vertical direction, the first water spray pipe 3 is located in the water tank 1 near the opening. The first water spray pipe 3 has a tubular structure with a hollow interior. The first water spray pipe 3 is provided with multiple first water spray nozzles, which are connected to the hollow interior structure of the first water spray pipe 3. The first water spray nozzles are used to spray water onto the broken strip located in the water tank 1. For example, the first water spray pipe 3 is provided with multiple first water spray nozzles in the direction of its own axis extension. The system has multiple evenly spaced first nozzles, each forming a first water spray nozzle. Along the extension direction of the axis of the first water spray pipe, the total spray area of ​​the multiple first water spray nozzles covers the width of the broken strip, ensuring that water can be sprayed throughout the width of the broken strip, thus guaranteeing a cooling effect. Two first limiting blocks 4 are located in the middle of the first water spray pipe 3. These two first limiting blocks 4 are spaced apart along the extension direction of the axis of the first water spray pipe 3, with a spacing of 10mm to 20mm between them to facilitate the passage of the steel wire rope. Preferably, the two first limiting blocks 4 are located in the first water spray pipe 3 facing the water tank 1. On one side of the heart, the two first limiting blocks 4 are flush with each other at their downward-facing ends, and the downward-facing ends of the two first limiting blocks 4 protrude from the bottom side of the first water spray pipe 3. The lower end face of each first limiting block 4 is a smooth curved surface to avoid scratching the strip steel. Each first limiting block 4 is provided with a second water spray nozzle, which is connected to the first water spray pipe 3. The first limiting block 4 has a liquid flow channel inside, one end of which is connected to the first water spray pipe 3, and the other end of which is connected to the second water spray nozzle. The water spray coverage of the second water spray nozzle covers at least the gap between the two first limiting blocks 4. The gap between the two first limiting blocks 4 is... For example, the second water nozzle can be opened to face the gap between the two first limiting blocks 4, through which the steel wire rope passes; the water supply equipment is connected to the first water pipe 3 to supply water to the first water pipe 3; the axis of the guide roller 5 is parallel to the axis of the first water pipe 3, and the guide roller 5 is rotatably installed in the water tank 1 around its own axis. The guide roller 5 is located on the side of the first water pipe 3 facing the other arc-shaped hanging plate 2 and is spaced apart from the first water pipe 3; relative to the plane where the opening is located, the distance between the guide roller 5 and the plane is greater than the distance between the first water pipe 3 and the plane, and in the vertical direction, the guide roller 5 is lower than the first water pipe 3.

[0036] The aforementioned annealing furnace strip breakage cooling device can be kept on standby in the factory when there is no strip breakage. It can be temporarily installed and used when a strip breakage occurs inside the furnace. Specifically, when using the aforementioned annealing furnace strip breakage cooling device to cool the broken strip, the water tank 1 can be placed on the outlet side of the annealing furnace. Since there is a sealing roller at the outlet of the annealing furnace, the sealing roller can be reused as a support roller. For ease of explanation, the arc-shaped hanging plate 2 near the first water spray pipe 3 in the water tank 1 is called the first arc-shaped hanging plate, and the other arc-shaped hanging plate 2 is called the second arc-shaped hanging plate. During installation, the first arc-shaped hanging plate is hung on the sealing roller, covering the upper side of the sealing roller. The second arc-shaped hanging plate can be hung on a roller (e.g., a transfer roller) near the annealing furnace on the production line, which is also reused as a support roller. Thus, the water tank 1 is fixedly installed on the outlet side of the annealing furnace. Since it is hung on the support rollers on both sides, it can be disassembled simply by lifting it upwards. This device is simple and reliable to install and disassemble, and very convenient to use. After installation, the broken strip is pulled out of the furnace using a steel wire rope. The steel wire rope pulls the broken strip, which passes over the upper surface of the first arc-shaped hanging plate. The first arc-shaped hanging plate hangs on the sealing roller, providing some protection to prevent the sealing roller from being damaged by heat. Then, the broken strip is pulled to water tank 1, with the steel wire rope passing under the first water spray pipe 3 and between the two first limiting blocks 4. Cooling water sprayed from the second water spray nozzle can cool the steel wire rope, and the two first limiting blocks 4 can restrict the steel wire rope from passing through the middle, preventing it from deviating during its forward movement and causing damage. When the belt passes under the first water spray pipe 3, the first water spray nozzle sprays cooling water towards the broken belt to cool it down. Then, the steel wire rope pulls the broken belt through the bottom of the guide roller 5 and finally passes over the top of the second arc-shaped hanging plate. Thus, the water tank 1 is placed on the conveyor route through which the broken belt is pulled out. The broken belt can be cooled down when it passes through the water tank 1. Since the guide roller 5 is lower than the first water spray pipe 3 and the second arc-shaped hanging plate, the part of the broken belt at the guide roller 5 is concave, which makes it easy for the cooling water to fall into the bottom of the water tank 1.

[0037] Therefore, the above-mentioned annealing furnace strip breaking cooling device is used for strip breaking cooling in heating furnaces, reducing manual labor. It only requires pulling the broken strip into the water tank to achieve cooling water spraying and cooling. The operation is simple and reliable, and it can also accurately cool the steel wire rope, effectively improving work safety, reducing the risk of burns to workers, and the cooling is achieved by spraying water during the pulling process, effectively improving the work efficiency of cooling operation.

[0038] To further improve the cooling efficiency and effect, two first water spray pipes 3 can be set. The two first water spray pipes 3 are set in parallel and spaced apart, and are located on the same side of the guide roller 5. The two first water spray pipes 3 spray water to the broken belt at the same time to cool it down, thereby further improving the cooling efficiency.

[0039] To facilitate the easy passage of the belt through the first water spray pipe and facilitate forward movement, multiple first roller rings are provided on the first water spray pipe 3. Each first roller ring is rotatably fitted around its own axis on the outer periphery of the first water spray pipe 3. The first roller rings avoid the first limiting block 4 and the first water spray nozzle, so as not to affect the limiting function of the first limiting block 4, nor to affect the water spraying function of the first water spray nozzle.

[0040] like Figure 4 As shown, based on the above-mentioned cooling device for the broken strip of the annealing furnace, a second water spray pipe 6 can be further provided. The axis of the second water spray pipe 6 is parallel to the axis of the first water spray pipe 3. The second water spray pipe 6 is installed in the water tank 1, and is located on the side of the guide roller 5 away from the first water spray pipe 3, and is spaced apart from the guide roller 5. Relative to the plane where the opening is located, the distance between the guide roller 5 and the plane is greater than the distance between the second water spray pipe 6 and the plane. Preferably, in the vertical direction, the second water spray pipe 6 is flush with the first water spray pipe 3, which is convenient for processing and manufacturing. The second water spray pipe 6 has a tubular structure with a hollow interior. The second water spray pipe 6 is equipped with... Multiple third water spray nozzles are provided, which are connected to the hollow structure inside the second water spray pipe 6. These third nozzles spray water towards the broken strip located in the water tank. For example, the second water spray pipe 6 has multiple evenly spaced second nozzles extending along its own axis. The nozzle opening of each second nozzle constitutes a third water spray nozzle. Along the axis of the second water spray pipe, the total spray area of ​​the multiple third nozzles covers the width of the broken strip, ensuring that water can be sprayed onto the entire width of the broken strip, thus guaranteeing a cooling effect. Preferably, the second water spray pipe 6 is connected to and communicates with the first water spray pipe 3, or the second water spray pipe 6 is connected to a water supply device. The second water spray pipe 6, on the other side of the guide roller 5, works in conjunction with the first water spray pipe 3 to spray water onto the broken strip for cooling, effectively further improving the cooling efficiency and effect.

[0041] Continue to refer to Figure 4As shown, two second limiting blocks 7 are provided in the middle of the second water spray pipe 6. The two second limiting blocks 7 are distributed at intervals along the extension direction of the axis of the second water spray pipe 6. The two second limiting blocks 7 are respectively opposite to the two first limiting blocks 4 in the arrangement direction of the first water spray pipe 3 and the second water spray pipe 6. The interval between the two second limiting blocks 7 is 10 mm to 20 mm. For example, the two second limiting blocks 7 are connected to the side of the second water spray pipe 6 facing the guide roller 5, and the downward ends of the two second limiting blocks 7 are flush and protrude from the bottom side of the second water spray pipe 6. The lower end face of each second limiting block 7 is a smooth curved surface, which can avoid The steel strip is designed to prevent scratches. Each second limiting block 7 is equipped with a fourth water spray nozzle, which is connected to the second water spray pipe 6. The second limiting block 7 has a liquid flow channel inside, with one end of the channel connected to the second water spray pipe 6 and the other end connected to the fourth water spray nozzle. The water spray coverage of the fourth water spray nozzle covers at least the gap between two second limiting blocks 7. The gap between two second limiting blocks 7 is used for the passage of the wire rope. After passing under the guide roller 5, the wire rope passes under the second water spray pipe 6 and extends out of the water trough 1. The wire rope passes between the two second limiting blocks 7, which can ensure that the wire rope does not deviate when moving forward. The wire rope can also be cooled again to improve the cooling effect.

[0042] Furthermore, the second water spray pipe 6 is provided with a second rolling ring. The second rolling ring is rotatably sleeved on the outer periphery of the second water spray pipe 6 around its own axis, which facilitates the smooth forward movement of the broken belt. The second rolling ring avoids the second limiting block 7 and the third water spray nozzle, so as not to affect the water spraying and cooling function of the second water spray pipe 6.

[0043] In one possible implementation, refer to Figure 2 As shown, the bottom wall of the water tank 1 has an inclined surface. The bottom wall of the water tank 1 is set as an inclined bottom wall. The depth of the part of the water tank 1 near one of the arc-shaped hanging plates 2 is greater than the depth of the part near the other arc-shaped hanging plate 2. For example, the depth of the part of the water tank 1 near the first arc-shaped hanging plate is greater than the depth of the part near the second arc-shaped hanging plate. A drain outlet is provided at the part of the bottom wall near the first arc-shaped hanging plate to facilitate the drainage of water in the water tank 1. Alternatively, the depth of the part of the water tank 1 near the second arc-shaped hanging plate is greater than the depth of the part near the first arc-shaped hanging plate. A drain outlet is provided at the part of the bottom wall near the second arc-shaped hanging plate to facilitate the drainage of water in the water tank 1.

[0044] To better protect the support rollers under the arc-shaped support plate, especially functional rollers in the production line such as sealing rollers and rubber rollers, which require enhanced protection, a cooling channel extending along its axis can be incorporated within the arc-shaped support plate. This cooling channel allows cooling water to pass through. The cooling channel has two opposing ends along the arc-shaped axis of the support plate, forming a coolant inlet and a coolant outlet. The coolant inlet of the cooling channel can be connected to a water supply system, and the coolant outlet can be connected to a drain pipe. Alternatively, the cooling channel can be connected to other coolant circulation equipment that supplies coolant.

[0045] As one implementation of the water supply equipment, the aforementioned water supply equipment may include a water tank, a filter, and a water pump; the bottom of the water tank is connected to and communicates with the water tank; the filter is placed inside the water tank, the inlet of the water pump is connected to the water tank through the filter, and the outlet of the water pump is connected to the first spray pipe. This water supply equipment can realize the recycling of cooling water, saving water resources.

[0046] As another way of implementing water supply equipment, the water supply equipment includes a tap water supply system. The first water spray pipe is connected to the tap of the tap water supply system through a hose, and the drain outlet of the water tank can be connected to the sewage tank through a drain pipe. The setup is simple and convenient.

[0047] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model.
