Description

Technical Field

[0001] This invention relates to the field of industrial production technology, and in particular to an automatic steel-burning control device for a hot-rolled stainless steel strip heating furnace. Background Technology

[0002] Steel rolling refers to the process of changing the shape of a steel billet by applying pressure between rotating rolls. The purpose of steel rolling, like other pressure processing, is to obtain the desired shape and to improve the internal quality of the steel. For example, hot-rolled stainless steel strip is produced by heating and extruding steel billets. A heating furnace is required in the process of heating the steel billets.

[0003] A search revealed a Chinese invention patent, publication number CN115823879B, entitled "A Steel Rolling Heating Furnace." This invention utilizes the coordination of a heating furnace tapping machine, a rough steel billet, and a pusher to achieve repeated feeding, heating, removal, and cooling of the rough steel billet. By introducing water into the inlet pipe, heat is exchanged with the high-temperature flue gas. Through the conduction of the heat exchange concave tube, the heat is transferred to the water source, thus realizing the recovery of waste heat.

[0004] However, in actual use, the above and similar technical solutions still have some problems:

[0005] 1. In the process of conveying steel billets to the heating furnace by means of a rotating roller conveyor, because the conveyor is located outside the heating furnace, it is difficult to completely feed the steel billets into the furnace. If the end of the billet is placed inside the furnace, it will have to withstand continuous high temperature, which will have an adverse effect on the service life of the equipment.

[0006] 2. When heat exchange is used to recover and utilize the heat from flue gas, the heat from the flue gas is stored by heating water and is not directly applied to the equipment itself. During the process of multiple heat conversions, a large amount of loss is likely to occur, which affects the energy utilization efficiency.

[0007] 3. The flue gas contains a lot of dust particles. When it is transported through pipelines for heat exchange, these particles tend to adhere to the inner wall of the pipeline. As the accumulated thickness increases, it will hinder heat transfer. There is a lack of effective cleaning mechanisms for such heat transfer and heat exchange structures. Summary of the Invention

[0008] The purpose of this invention is to overcome the shortcomings of the prior art by proposing an automatic steel-burning control device for a hot-rolled stainless steel strip heating furnace that facilitates the conveying and removal of steel billets, allows the heat from the flue gas to be directly applied to the steel billets, and facilitates the cleaning of dust particles.

[0022] Compared with the prior art, the present invention provides an automatic steel-burning control device for a hot-rolled stainless steel strip heating furnace, which has the following beneficial effects:

[0023] 1. This automatic steel-burning control equipment for hot-rolled stainless steel strip heating furnace uses a pair of clamping rods to hold the rolled steel billet. The rims of a pair of push rollers abut against both sides of the rolled steel billet to clamp and fix it. When the slider drives the clamping rods to move, it pushes the rolled steel billet into the heating furnace. The pair of clamping rods are set at an angle, which can completely feed the rolled steel billet into the heating furnace, and at the same time facilitate the subsequent removal of the rolled steel billet, which facilitates automatic clamping, feeding and unloading.

[0024] 2. This automatic steel-burning control equipment for hot-rolled stainless steel strip heating furnace allows high-temperature flue gas generated by the furnace to enter the flue pipe and then the inner chamber, where it is heated. The heat diffuses between the inner and outer chambers, driving the drive rod to rotate. Under the action of the sprocket and chain, multiple push plates rotate. The push plates are used to support the rolled steel billet, facilitating preheating of the billet and improving the heating efficiency of the furnace. At the same time, it facilitates the utilization of waste heat from the flue gas, saving resources.

[0025] 3. In this automatic steel-burning control equipment for hot-rolled stainless steel strip heating furnace, after the hot flue gas enters the inner chamber, it is turbulent by the baffle plate, so that the heat in the flue gas can be fully released. The dust particles in the flue gas will adhere to the inner wall of the inner chamber. When the drive rod rotates, the drive rod drives the scraper to rotate. The scraper scrapes off the dust particles adhering to the inner wall of the inner chamber, causing them to fall off. Air is blown into the flue pipe, and a large amount of air rushes into the inner chamber, raising the scraped dust particles and blowing them out through the exhaust pipe, thus facilitating the cleaning of dust particles inside the inner chamber. The operation is convenient. Attached Figure Description

The pair of clamping rods 45 are opened and closed by the electric push rod 48, so as to facilitate the clamping of the rolled steel billet. The pair of clamping rods 45 are inclined towards the heating furnace 1 to facilitate the feeding of the rolled steel billet into the heating furnace 1.

[0040] In this invention, a pushing mechanism 6 is connected to the clamping rod 45. The pushing mechanism 6 includes a pusher 61. The bottom end of the clamping rod 45 is rotatably connected to the pusher 61. The rim of the pusher 61 is used to abut against the side wall of the rolled steel billet. A second motor 64 is mounted on the clamping rod 45. A transmission rod 62 is rotatably connected to the clamping rod 45. The output shaft of the second motor 64 is connected to the end of the transmission rod 62 through a coupling. A second helical gear 66 is mounted on the shaft end of the pusher 61. A first helical gear 65 is mounted on the end of the transmission rod 62. The first helical gear 65 and the second helical gear 66 mesh with each other, thereby driving the transmission rod 62 to rotate through the second motor 64. The first helical gear 65 and the second helical gear 66 achieve tilting transmission, drive the pusher 61 to rotate, and drive the rolled steel billet to move.

[0041] In this invention, an auxiliary wheel 63 is rotatably connected to one end of the pusher 61, and the auxiliary wheel 63 is parallel to the axis of the pusher 61, thereby ensuring the stability of the pusher 61 in clamping the rolled steel billet.

A first motor 44 is installed on the truss 41, and the output shaft of the first motor 44 is connected to the shaft end of the lead screw 43 through a coupling, thereby facilitating the sliding of the slider 42. A guide rod is installed on the truss 41, and the slider 42 is slidably connected to the guide rod, thereby facilitating the stable sliding of the slider 42.

[0044] Example 2: Based on Example 1, an automatic steel firing control device for a hot-rolled stainless steel strip heating furnace is provided. A preheating mechanism 3 is connected to the heating furnace 1. The preheating mechanism 3 includes an outer box 36. The heating furnace 1 is equipped with an outer box 36, and an inner box 38 is connected inside the outer box 36. The inner box 38 is connected to the flue gas outlet of the heating furnace 1. A pair of drive rods 311 are rotatably connected to the outer box 36, passing through the inner box 38. Both ends of the drive rods 311 are equipped with sprockets 310. Chains 312 are wound and meshed on the pair of sprockets 310 on the same side. Multiple push plates 39 are installed between the pair of chains 312. A placement plate 34 and a discharge plate 37 connected to the interior are installed on the outside of the outer box 36. The two chains 312 rotate synchronously, thereby driving the multiple push plates 39 to rotate. The push plates 39 are used to support the rolled steel billet, so that the rolled steel billet is preheated in a closed space. After preheating, it is automatically sent out to facilitate the utilization of the waste heat of the flue gas.

[0045] In this invention, the inner box 38 is fixedly connected to a flue pipe 31 and an exhaust pipe 35 at both ends. Both the flue pipe 31 and the exhaust pipe 35 are fixedly connected to the outer box 36. The flue pipe 31 is fixedly connected to the exhaust port of the heating furnace 1. The inner box 38 is connected to the exhaust port of the heating furnace 1 through the flue pipe 31, so as to facilitate the delivery of the hot smoke discharged from the heating furnace 1 into the inner box 38.

[0046] In this invention, a drive mechanism 7 is connected to the outer casing 36. The drive mechanism 7 includes a third motor 71. The third motor 71 is installed on the outer casing 36. A second gear 72 is installed on the output shaft of the third motor 71. A third gear 73 is installed on the shaft end of one of the drive rods 311. The second gear 72 meshes with the third gear 73, thereby facilitating the rotation of the drive rod 311 and facilitating the control of the preheating time of the rolled steel billet.

[0047] In this invention, a pair of mounting rods 33 are installed at both ends of the push plate 39. The mounting rods 33 are fixedly connected to the two shaft ends of one link of the chain 312. The multiple push plates 39 are distributed at equal intervals, which facilitates the installation of the push plates 39.

[0048] In this invention, the discharge plate 37 is located on one side of the bottom end of the outer box 36 and is inclined downward. The bottom end of the discharge plate 37 extends above the conveyor 2, which facilitates the automatic discharge of the preheated rolled steel billet.

[0049] Example 3: Based on Example 2, an automatic steel burning control device for a hot-rolled stainless steel strip heating furnace is provided. Multiple scrapers 314 are fixedly connected to the drive rod 311. The scrapers 314 are located inside the inner box 38. The scrapers 314 rotate with the drive rod 311, thereby facilitating the scraping of dust particles adhering to the inner wall of the inner box 38. Multiple baffles 313 are fixedly connected inside the inner box 38, thereby allowing the heat in the flue gas to be fully released.

[0050] In this invention, the baffle 313 is located between two adjacent scrapers 314, thereby enabling the scraping of dust particles adhering to the side wall of the baffle 313. A branch pipe 32 is installed on the side wall of the flue 31, and the branch pipe 32 is connected to the flue 31. A fan 5 is installed at the end of the branch pipe 32. The branch pipe 32 is inclined away from the outer casing 36, so that when cleaning the dust particles in the inner casing 38, the fan 5 is started, and a large amount of air rushes into the inner casing 38, raising the scraped dust particles and blowing them out through the discharge pipe 35, thereby facilitating the cleaning of dust particles.

[0051] Working principle: When the electric push rod 48 is activated, it retracts, pulling a pair of clamping rods 45 closer to clamp the rolled steel billet on the conveyor 2. Each clamping rod 45 is equipped with a rack 47, which is driven by the first gear 46, causing the clamping rods 45 to move synchronously towards each other. This moves the rolled steel billet to the center of the conveyor 2, facilitating alignment with the heating furnace 1. The rims of a pair of push rollers 61 abut against both sides of the rolled steel billet, and simultaneously, the rims of a pair of auxiliary rollers 63 also abut against both sides of the rolled steel billet, thus clamping and fixing the billet. (Second motor) 64 is a brake motor, a power actuator that integrates a motor and a braking device. Its core function is to quickly and reliably stop the motor shaft from rotating and keep it stationary when power is off. Therefore, when the second motor 64 is not working, the push wheel 61 cannot rotate. The first motor 44 is then started, driving the lead screw 43 to rotate, which in turn drives the slider 42 to move. A guide rod is mounted on the truss 41, and the slider 42 is slidably connected to the guide rod, facilitating its sliding. When the slider 42 slides, it drives a pair of clamping rods 45 to move, which in turn drives the rollers 61 to move. The steel billet moves on the rotating rollers of conveyor 2. The clamping rod 45 tilts towards the heating furnace 1, and the pusher 61 at the end of the clamping rod 45 can extend into the heating furnace 1. After pushing the rolled steel billet into the heating furnace 1, the second motor 64 is started, driving the transmission rod 62 to rotate, which in turn drives the first helical gear 65 and the second helical gear 66 to rotate, thereby driving the rolled steel billet to move and completely enter the heating furnace 1. At the same time, it prevents the end of the rolled steel billet from completely disengaging from the pusher 61, making it easier to clamp and pull out the rolled steel billet later. After the rolled steel billet is sent into the heating furnace 1, the pusher 61 and the rolled steel billet are aligned. Separation is performed to remove the pusher 61 from the heating furnace 1 to avoid damage caused by the high temperature inside the heating furnace 1. After the steel billet is heated, the pusher 61 is inserted back into the heating furnace 1 to clamp the steel billet and pull it out, allowing it to enter the conveyor 2. The pusher 61 is driven to rotate in the opposite direction, moving it to the end of the conveyor 2 away from the heating furnace 1. The conveyor 2 is in the shape of a slide, with the end of the conveyor 2 away from the heating furnace 1 tilted downwards. The rotating roller of the conveyor 2 is concave in the middle, so that the heated steel billet automatically slides to the end of the conveyor 2, making it easy to lift it away by the overhead crane.

[0052] The high-temperature flue gas generated by the heating furnace 1 enters the flue pipe 31 and then enters the inner box 38, heating the inner box 38. The heat diffuses between the inner box 38 and the outer box 36. The steel billet to be heated is placed on the placement plate 34. The third motor 71 is started, driving the second gear 72 and the third gear 73 to rotate, thereby driving the drive rod 311 to rotate. Under the action of the sprocket 310 and the chain 312, the pair of drive rods 311 are driven to rotate synchronously, thereby driving the sprocket 310 and the chain 312 at the other end to move synchronously. Through the connection of the mounting rod 33, the... Multiple push plates 39 between a pair of chains 312 rotate. The push plates 39 are used to support the rolled steel billets and push the rolled steel billets on the placement plate 34 one by one into the outer box 36, which facilitates preheating. The preheated rolled steel billets are pushed by the push plates 39 and slide out through the discharge plate 37 and fall onto the conveyor 2, which facilitates pushing them into the heating furnace 1. The operation is convenient. By heating the preheated rolled steel billets, the heating efficiency is higher. At the same time, it is convenient to utilize the waste heat of the flue gas, saving resources. The end of the discharge pipe 35 can be connected to the flue gas processor to avoid direct emission and environmental pollution.

[0053] After the hot flue gas enters the inner chamber 38, it is turbulent by the baffle 313, allowing the heat in the flue gas to be fully released. Dust particles in the flue gas will adhere to the inner wall of the inner chamber 38. When the drive rod 311 rotates, the drive rod 311 drives the scraper 314 to rotate. The scraper 314 scrapes off the dust particles adhering to the inner wall of the inner chamber 38, causing them to fall off. During regular cleaning and maintenance, the fan 5 is started. The branch pipe 32 is equipped with a one-way valve, which can restrict the flue gas inside the flue pipe 31 from entering the branch pipe 32. When the fan 5 is working, it blows air into the branch pipe 32, which enters the flue pipe 31 through the one-way valve. Due to the inclined setting of the branch pipe 32, a large amount of air rushes into the inner chamber 38, raising the scraped dust particles and blowing them out through the discharge pipe 35, thus facilitating the cleaning of dust particles inside the inner chamber 38. The operation is convenient.

[0054] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
