Description

Technical Field

[0001] This invention relates to the field of steelmaking continuous casting equipment technology, and more specifically, to a billet discharge system for a continuous casting machine compatible with irregular billets / rectangular billets. Background Technology

[0002] Baowu Maanshan Iron & Steel's Long Products Division, Zone 1, has four 50t converters. Its casting system includes one 4-strand small shaped billet continuous casting machine, one 3-strand large shaped billet continuous casting machine, and two 6-strand square billet continuous casting machines. Baowu Maanshan Iron & Steel's Long Products Division, Zone 2, has three 120t converters, three argon blowing units, three LF furnaces, and two vacuum treatment facilities (one VD and one RH). Its casting system includes one 2-strand heavy H-beam shaped billet continuous casting machine, one 6-strand small square billet continuous casting machine, and two CSP production lines.

[0003] According to the overall production development plan, after the new special steel project for capacity replacement is finally completed and put into operation, the steelmaking workshop of Zone 1 of the Long Products Business Division will be shut down, while the existing smelting system of Zone 2 will be retained. The existing supply of materials for large and small H-beams and medium-sized steel sections will be changed from the steelmaking workshop of Zone 1 of the Long Products Business Division to the supply of materials from Zone 2.

[0004] According to the requirements of Phase I of the plan, two converters in the steelmaking workshop of Zone 1 of the Long Products Division will be shut down, and one 4-strand small irregular billet continuous casting machine and the No. 2 6-strand square billet continuous casting machine in the casting system will be shut down accordingly. In order to solve the billet source for the two rolling production lines of small H-beams and medium-sized sections after the shutdown of the continuous casting machine in Zone 1 of the Long Products Division, it is urgent to design a new type of irregular billet / rectangular billet compatible continuous casting machine. Zone 2 of the Long Products Division is required to form a capacity to supply 1.13 million tons / year of continuous casting billets for small H-beams and medium-sized sections of the Long Products Division. Among them, 610,000 tons of small square billets (165×165mm) and rectangular billets (165×225mm) will be supplied to the medium-sized section production line, and 520,000 tons of irregular billets (430×300×90mm and 320×220×85mm) will be supplied to the small H-beam production line.

[0005] In production practice, due to factory renovations, the above-mentioned situations often arise. It is necessary to meet the production capacity requirements, but the limited factory space and the current equipment status restrict the arbitrary distribution of multiple sets of equipment and make it impossible to arbitrarily add new production lines or large equipment. How to make breakthroughs and modifications to the existing equipment to adapt to the existing factory space environment and production requirements poses a new challenge to production.

[0006] For example, patent CN112122570B discloses a method for using a compact layout system for the billet discharge area of ​​a billet continuous casting machine. This design addresses the problem of limited plant space in the billet discharge area of ​​traditional billet continuous casting machines, where equipment such as cooling beds and steel transfer machines cannot be arranged. It increases the cooling time of the billet on the cooling bed without increasing the length of the cooling bed, which can effectively reduce the space required. This design is also based on the optimization and adjustment of equipment according to the limitations of plant space distribution, but it can only optimize the spatial layout and cannot be applied to the compatibility issues of irregular billets and square billets mentioned above. Summary of the Invention

[0007] 1. The technical problem that the invention aims to solve

[0008] This invention aims to provide a billet output system for a continuous casting machine that is compatible with irregular billets / rectangular billets, in order to adapt to the needs of production transformation. It modifies the original independent square billet production line and irregular billet production line to achieve compatible production of square billets and irregular billets, and effectively reduces the overall space occupied, so as to meet the production capacity requirements within a limited layout space.

[0009] 2. Technical Solution

[0010] To achieve the above objectives, the technical solution provided by the present invention is as follows:

[0011] The present invention provides a billet discharge system for a continuous casting machine compatible with irregular billets / rectangular billets, comprising an irregular billet discharge assembly and a rectangular billet discharge assembly, wherein the irregular billet discharge assembly and the rectangular billet discharge assembly have at least partially shared transmission components.

[0012] At the end of the shared transmission component, there are first rectangular billet cooling beds and rectangular billet collection platforms, followed by irregular billet cooling beds and irregular billet collection platforms. The rectangular billets transmitted by the shared transmission component enter the rectangular billet cooling beds and rectangular billet collection platforms; the irregular billets are then conveyed forward until they enter the irregular billet cooling beds and irregular billet collection platforms.

[0013] Furthermore, the rectangular billet unloading assembly adopts a bidirectional unloading design. The end of the shared transmission assembly is provided with an unloading roller conveyor. On each side of the unloading roller conveyor, there is a set of rectangular billet unloading cooling beds and a rectangular billet collection platform, and the unloading directions on both sides are opposite.

[0014] Furthermore, the billet unloading assembly adopts a bidirectional unloading design. The end of the billet unloading roller table one is provided with billet unloading roller table two. On each side of billet unloading roller table two, there is a set of billet unloading cooling bed and billet collection platform, and the unloading directions on both sides are opposite.

[0015] Furthermore, the rectangular billet unloading assembly also includes a transverse transfer device, which is located above the unloading roller conveyor. This device pushes the rectangular billet onto the rectangular billet unloading cooling bed, and reciprocates towards both sides of the cooling bed. During this reciprocating motion, adjacent batches of rectangular billets are transferred to the cooling beds on both sides, achieving bidirectional transfer. Correspondingly,

[0016] The shaped billet unloading assembly also includes a steel scooping device, which is located on the upper part of the billet unloading roller conveyor. The steel scooping device reciprocates towards the shaped billet unloading cooling beds on both sides. During the reciprocating process, adjacent batches of shaped billet castings are transferred to the cooling beds on both sides, realizing bidirectional transfer.

[0017] Furthermore, the shared transmission components sequentially include a despindle removal device, an intermediate roller conveyor, a swing roller conveyor, a fire cutting machine and dust removal components, a cutting slag collection components, and a fixed-weight weighing roller conveyor;

[0018] The ingot removal device receives the dummy bar and billet from the straightening machine and is used to remove the dummy bar, i.e., separate the billet from the dummy bar; the intermediate roller conveyor receives and conveys the billet from the straightening machine; the oscillating roller conveyor receives and supports the billet conveyed by the intermediate roller conveyor; the fire cutting machine and dust removal assembly are used to cut the billet to length and collect cutting fumes; the cutting slag collection assembly is used to collect cutting slag and the cut-off ends; and the fixed-weight weighing roller conveyor is used to convey and support the billet and to weigh the fixed-length billet online.

[0019] At the end of the fixed-weight weighing roller conveyor, there are two billet discharge roller conveyors in sequence: billet discharge roller conveyor one and billet discharge roller conveyor two. Billet discharge roller conveyor one is used to support and transport irregularly shaped billet castings and rectangular billet castings, while billet discharge roller conveyor two is used to support and transport irregularly shaped billet castings.

[0020] Furthermore, the intermediate roller conveyor includes a billet measuring roller for measuring the billet length and determining the billet size, which is calculated using an encoder; the oscillating roller conveyor uses hydraulic oscillation and an independently driven water-cooled roller conveyor to prevent flame cutting of the roller body.

[0021] Furthermore, the rectangular billet unloading assembly also includes a steel-turning device and a transition platform. Both the steel-turning device and the transition platform are located on the side of the billet unloading roller table one. The function of the steel-turning device is to turn the rectangular billet on the billet unloading roller table one onto the slide for steel transfer. The transition platform is located at the front end of the rectangular billet unloading cooling bed and is used to buffer the rhythm when the billet is loaded onto the bed.

[0022] Furthermore, the end of the fixed-weight weighing roller conveyor is equipped with a lifting baffle, and the end of the billet discharge roller conveyor is equipped with a fixed baffle. The lifting baffle is used to stop the billet casting and control the running rhythm of the billet casting, while the fixed baffle is used to stop the billet alignment.

[0023] Furthermore, an online storage device for the guillotine bar is provided in front of the billet discharge roller conveyor. This device is used to store the guillotine bar online, thus shortening the online replacement time of the guillotine bar.

[0024] Furthermore, it also includes an infrared cluster assembly and a marking machine; the infrared cluster assembly is used for billet tracking; and the marking machine is used for marking the billet.

[0037] The present invention will be further described below with reference to embodiments.

[0038] Example

[0039] The billet discharge system of the shaped billet / rectangular billet compatible continuous casting machine in this embodiment includes a shaped billet discharge assembly and a rectangular billet discharge assembly, and the shaped billet discharge assembly and the rectangular billet discharge assembly have at least a portion of a shared transmission assembly; at the end of the shared transmission assembly, a rectangular billet discharge cooling bed 11 and a rectangular billet collection platform 12 are first provided, and then a shaped billet discharge cooling bed 15 and a shaped billet collection platform 16 are distributed. The rectangular billets transmitted by the shared transmission assembly enter the rectangular billet discharge cooling bed 11 and the rectangular billet collection platform 12; the transmitted shaped billets continue to be conveyed forward until they enter the shaped billet discharge cooling bed 15 and the shaped billet collection platform 16.

[0040] Specifically, the rectangular billet unloading assembly adopts a bidirectional unloading design. The end of the shared conveyor assembly is equipped with an unloading roller conveyor 7. On each side of the unloading roller conveyor 7, there is a set of rectangular billet unloading cooling beds 11 and rectangular billet collecting platforms 12, with the unloading directions on both sides facing each other. Similarly, the irregular-shaped billet unloading assembly adopts a bidirectional unloading design. The end of the unloading roller conveyor 7 is equipped with an unloading roller conveyor 13. On each side of the unloading roller conveyor 13, there is a set of irregular-shaped billet unloading cooling beds 15 and irregular-shaped billet collecting platforms 16, with the unloading directions on both sides facing each other.

[0041] In practice, the rectangular billet unloading assembly also includes a transverse transfer device 9, which is located above the unloading roller conveyor 7. This device pushes the rectangular billet casting onto the rectangular billet unloading cooling bed 11. The transverse transfer device 9 reciprocates towards both sides of the rectangular billet unloading cooling bed 11, transferring adjacent batches of rectangular billets to the cooling beds on both sides during the reciprocating motion, thus achieving bidirectional transfer. Correspondingly, the irregular billet unloading assembly also includes a steel-collecting device 14, which is located at... Above the billet discharge roller conveyor 13, the steel scooping device 14 reciprocates towards the shaped billet discharge cooling beds 15 on both sides. During the reciprocating process, adjacent batches of shaped billet castings are transferred to the cooling beds on both sides, realizing bidirectional transfer. Specifically, the steel scooping device 14 adopts a double transverse trolley for steel scooping, which can scoop two castings at a time and realize bidirectional steel transfer. The transverse movement and steel scooping lifting of the steel scooping device 14 are precisely controlled by an encoder, so that the castings can be directly transferred to the shaped billet discharge cooling bed 15 in both directions.

[0042] Specifically, the shared transmission components sequentially include a billet removal device 1, an intermediate roller conveyor 2, a swing roller conveyor 3, a fire-cutting machine and dust removal assembly 4, a cutting slag collection assembly 5, and a constant-weight weighing roller conveyor 6. The billet removal device 1 receives the dummy bar and billet from the straightening machine, and is used for dummy bar removal, i.e., separation of the billet from the dummy bar. The intermediate roller conveyor 2 receives and transports the billet from the straightening machine. It also includes a billet centering device for centering the dummy bar and billet. The intermediate roller conveyor 2 includes a billet measuring roller for measuring the billet length and determining the billet's fixed length. An encoder is used to measure and calculate the billet's running length, primarily for determining the starting position of the continuous casting machine's fire-cutting machine. The swing roller conveyor 3 receives and supports the billet transported by the intermediate roller conveyor 2. The swing roller conveyor 3 uses hydraulic swing and independent drive water-cooled rollers to prevent billet deformation and ensure billet stability. The quality of the cut surface; the use of the swing roller conveyor 3 can optimize and shorten the tail billet length, and improve the metal yield of the continuous casting machine; it also realizes the swing of the roller body and avoids flame cutting of the roller body; the fire cutter and dust removal component 4 is used to cut the billet to length and collect the cutting dust to improve the production environment; the cutting slag collection component 5 is used to collect the cutting slag and the material head and tail of the cut; the fixed weight weighing roller conveyor 6 is used to transport and support the billet and to weigh the fixed length billet online. The fixed weight is optimized according to the fixed weight requirements of steel rolling. The end of the fixed weight weighing roller conveyor 6 is equipped with a lifting baffle 17; at the end of the fixed weight weighing roller conveyor 6, the billet discharge roller conveyor 1 7 and the billet discharge roller conveyor 2 13 are set in sequence. The billet discharge roller conveyor 1 7 is used to support and transport the irregular billet and the square and rectangular billet. The billet discharge roller conveyor 2 13 is used to support and transport the irregular billet. The end of the billet discharge roller conveyor 1 7 is also equipped with a lifting baffle 17. The end of the billet discharge roller conveyor 2 13 is equipped with a fixed baffle 18. The function of the lifting baffle 17 is to stop the casting of the billet and control the running rhythm of the billet, while the function of the fixed baffle 18 is to stop the alignment of the billet. An online ingot dummy bar storage device 20 is also provided in front of the billet discharge roller conveyor 7. The online ingot dummy bar storage device 20 is used for online storage of the ingot dummy bar, shortening the online replacement time of the ingot dummy bar and improving production efficiency.

[0043] Specifically, the rectangular billet unloading assembly also includes a steel-turning device 8 and a transition platform 10, which still adopt the traditional steel-turning design. The function of the steel-turning device is to turn the rectangular billet on the unloading roller table 1 to the slide for steel transfer. The steel-turning device 8 and the transition platform 10 are both located on the side of the unloading roller table 7. The transition platform 10 is located at the front end of the rectangular billet unloading cooling bed 11 and is used to buffer the rhythm when the billet is loaded onto the bed.

[0044] The billet unloading system in this embodiment also includes an infrared cluster component and a marking machine 19. The infrared cluster component is used for billet tracking to realize intelligent control of the billet unloading system. The marking machine 19 is set at the collection platform and is used for marking the billet. The descaling and marking separation design of the marking machine 19 improves the descaling effect of the billet and increases the marking efficiency.

[0045] The following will elaborate further based on practical production experience.

[0046] According to the requirements of Phase I of the plan, considering the converter capacity, on-site facilities, and actual logistics conditions in Zone 2, the newly built continuous casting machine in Zone 2 must be controlled within a width of 105m in the casting flow direction. Based on the design technology and equipment configuration requirements of the continuous casting machine, only one continuous casting machine can be designed. Therefore, the continuous casting machine design must be able to accommodate four cross-sections: 430×300×90mm and 320×220×85mm for irregular billets, 165×165mm for small square billets, and 165×225mm for rectangular billets, thus enabling the production of both irregular and rectangular billets. Based on the furnace-machine matching requirements of the continuous casting machine, and considering the design requirements for the flow field, superheat, continuous casting, and service life of the tundish, a new 6-machine, 6-ton continuous casting machine is required. This continuous casting machine is compatible with both shaped and rectangular billets, with a flow spacing of 1800mm and a basic arc radius of R12000mm. The maximum casting speed for square billets is 3.50m / min, and for shaped billets, it is 2.05m / min. The standard length for square billets is 6-11m, and for shaped billets, it is 6-12m. The fastest billet exit time is 17.5s for square billets and 39.3s for shaped billets. The billet exit system requires a cutting span of 28m and an exit span of 31m (39m span overall, considering a logistics transport width of nearly 8m). Within a compact 61.5m x 105m plant space, designing a billet exit system using current methods is simply impossible. This embodiment's billet exit system is a breakthrough design based on this specific situation.

[0047] Because rectangular billets require tumbling for cooling and straightening during unloading, while irregularly shaped billets are not suitable for this method, the unloading cooling and collection system of the continuous casting machine needs to employ different unloading production processes. This requires the design and configuration of independent unloading cooling and collection equipment. In this embodiment, considering the billet temperature requirements during tumbling for cooling and straightening of rectangular billets, the unloading production process prioritizes the arrangement of unloading cooling and collection equipment for rectangular billets. The unloading cooling and collection process for rectangular billets adopts a "turning steel—pushing steel—separating steel walking cooling bed—collecting platform" process, while the unloading of irregularly shaped billets adopts a "scooping steel—separating steel walking cooling bed—collecting platform" design for the continuous casting machine unloading system.

[0048] Given that the fastest billet discharge rhythm on a continuous casting machine is 17.5 seconds, if traditional unidirectional steel discharge is used, the running rhythm of the steel-separating walking cooling bed should be less than 17.5 seconds. An excessively fast cooling bed running rhythm makes it difficult to guarantee equipment reliability and safety. Simultaneously, to ensure billet cooling, the length of the steel-separating walking cooling bed would be too long, and the plant space would not meet the requirements for process layout and billet off-line production. Furthermore, using unidirectional steel discharge with a steel-separating walking cooling bed and collection platform results in a large equipment load and a fast rhythm, increasing investment costs for the hydraulic control system. Therefore, this embodiment adopts a bidirectional steel discharge process: steel turning—bidirectional steel pushing—two sets of steel-separating walking cooling beds—two sets of collection platforms. The hydraulic lifting and other actions of the two sets of steel-separating walking cooling beds and collection platforms are differentially staggered, simultaneously reducing the running rhythm of the steel-separating walking cooling beds and collection platforms, thereby reducing hydraulic control investment costs and better meeting production process requirements and improving equipment reliability and safety.

[0049] Since the fastest billet output rhythm of irregularly shaped billets in continuous casting machines is 39.3 seconds, if traditional unidirectional steel output is used, although the billet output method of the steel-separating walking cooling bed-collecting platform meets the process requirements, even if the steel scooping device can scoop two strands and two billets at a time, the complexity of the steel scooping process still makes it difficult to meet the process production rhythm requirements. This embodiment adopts bidirectional steel output, that is: a steel scooping device with two cars - bidirectional steel transfer - two sets of steel-separating walking cooling beds - two sets of collecting platforms process design configuration; the hydraulic lifting and other actions of the two sets of steel-separating walking cooling beds - collecting platforms adopt differential staggered control, and the hydraulic power station is shared with the square and rectangular billets; at the same time, the operating rhythm of the steel-separating walking cooling bed - collecting platform is reduced, thereby effectively reducing the investment cost of hydraulic control, and can also better meet the production process requirements and improve the reliability and safety performance of equipment operation. In practice, the steel scooping device adopts a dual-car steel scooping system, with each car capable of scooping two streams and two billets at a time, and each car responsible for scooping three streams. Since the stream spacing is 1800mm, the two cars are controlled by encoders and interlocked. When one car is scooping the third or fourth stream, the other car must not scoop the fourth or third stream.

[0050] In this embodiment, the continuous casting machine adopts bidirectional billet discharge, which not only reduces the billet discharge rate but also better ensures the reliability of descaling and marking of the billet. Furthermore, the rectangular billet discharge cooling bed 11, with its hydraulically driven lifting and stepping cooling bed toothed plate, optimizes the tooth pitch and tooth shape, as well as the hydraulically driven lifting and stepping parameters, according to the cross-sectional dimensions of the rectangular billet. This effectively improves the cooling effect and automatic tumbling and straightening of the billet, and optimizes the length of the cooling bed to meet existing layout space requirements. The irregular billet discharge cooling bed 15, with its hydraulically driven lifting and stepping cooling bed, uses a flat toothed plate. Based on the cross-sectional dimensions of the irregular billet, the hydraulically driven lifting and stepping parameters are optimized accordingly, effectively improving the cooling effect and quality of the billet, and optimizing the length of the cooling bed to meet existing layout space requirements.

[0051] This embodiment optimizes the design of a continuous casting machine's billet discharge system in a confined space, ensuring compatibility with irregularly shaped / rectangular billets. Both irregularly shaped and rectangular billets utilize bidirectional discharge, meeting the high-paced production requirements of the continuous casting machine and reducing investment costs while guaranteeing safe and reliable operation. Furthermore, it enables automated interlocking control of all equipment in the discharge system, improving the machine's production safety and intelligence, and significantly reducing labor costs. Simultaneously, it enhances equipment safety and reliability, increases production efficiency, and provides innovative design concepts for multi-section compatible continuous casting machines. In particular, it offers a successful example for the efficient, intelligent, and high-efficiency upgrading and transformation of continuous casting machines.

[0052] The present invention and its embodiments have been described above illustratively. This description is not restrictive and is merely one embodiment of the present invention, and is not actually limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
