Description

Technical Field

[0001] This invention relates to the field of metallurgical equipment technology, and in particular to a hot repair machine for slag removal from a liquid metal transfer ladle. Background Technology

[0002] In the liquid metal production process of the metallurgical industry, after the molten steel or iron is poured, the transfer ladle (such as a steel ladle or iron ladle) must be cleaned of slag and its lining repaired to ensure its safe reuse and extend its service life. Currently, such operations mostly rely on manual labor in conjunction with simple tilting devices, typically using robotic arms or articulated supports to achieve tilting operations at limited angles. However, existing technologies have revealed many shortcomings in practical applications: First, it is difficult to continuously and precisely adjust the attitude of the transfer bag during the flipping process, and there is a lack of a reliable arbitrary angle locking mechanism, resulting in low precision in controlling the amount of slag residue. At the same time, the bag is prone to shaking during hot repair operations, which seriously affects the stability and quality of the repair operation. Second, the work area generally lacks effective physical isolation measures, and the splashing of high-temperature slag and the accompanying flue gas are difficult to effectively contain, which not only poses a safety threat to operators but also pollutes the work environment. Third, slag dumping and hot repair are usually completed by two independent sets of equipment, requiring multiple transfers and repositioning of the transfer bag, which significantly prolongs the operation cycle and reduces overall efficiency. In addition, existing equipment is difficult to adjust in terms of high adaptability and positioning accuracy when facing transfer bags of different specifications, and has poor versatility, making it difficult to meet the needs of modern metallurgical production for efficient, flexible, and safe operations.

[0003] A search revealed a patent, CN102538473B, for an air-cooled transfer chute for an oxidation pellet chain grate machine. This patent relates to a chute structure for transferring high-temperature materials, which improves the chute's service life under high-temperature conditions by using a cooling air box and heat-resistant steel bolt connections. Although this design optimizes structural strength and heat resistance, it is only a fixed chute structure and lacks the functions of actively tilting, emptying slag, or performing hot repairs on the container. It cannot achieve multi-angle attitude adjustment and stable support for liquid metal transfer packages, nor does it integrate a hot repair operation platform. Therefore, it cannot meet the core requirement of integrated slag emptying and hot repair operations.

[0004] A search revealed a fully automated roller-type heat treatment production line for large steel cylinders, patent number CN114657339B. This patent discloses a segmented continuous heat treatment production line that uses a transverse transfer cart to automatically transfer workpieces between the quenching furnace and the tempering furnace, and employs independent roller groups to reduce heat loss. Although the system achieves automated transfer and heat treatment of high-temperature containers, its core function focuses on the heat treatment process itself, rather than on slag removal and lining repair in the empty state. The production line lacks a tilting mechanism, making it unable to tilt and remove slag at large angles, and it does not integrate the positioning, support, and protective structures required for heat repair operations. Therefore, its applicability in the maintenance of liquid metal transfer containers is limited.

[0005] The aforementioned problems indicate that existing technologies lack a dedicated device that integrates efficient slag removal, stable hot repair, safety protection, and flexible adaptability. Therefore, this invention provides a liquid metal transfer ladle slag removal and hot repair machine. It aims to address the shortcomings of existing technologies in terms of functional integration, operational safety, and work efficiency through a large-angle stepless tilting mechanism, an arbitrary position locking device, an integrated hot repair platform, and a slag and dust isolation system. This provides the metallurgical industry with an efficient, intelligent, and safe transfer ladle maintenance solution. Summary of the Invention

[0006] This invention provides a liquid metal transfer bag slag removal and hot repair machine, which overcomes the shortcomings of existing technologies in terms of stability, compatibility and operating efficiency.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] This invention provides a hot repair machine for slag removal from a liquid metal transfer ladle, comprising a conveying system, a tilting system, a collection system, and a protective system. The conveying system carries and positions the transfer ladle to the tilting station; the tilting system drives the transfer ladle to continuously tilt within a range of 0° to 180°, and supports stopping and locking at any angle; the collection system receives the dumped high-temperature slag; and the protective system isolates high-temperature splashes and discharges fumes and dust generated during the operation.

[0009] Furthermore, the conveying system includes a flatcar and a smaller flatcar housed inside the flatcar. The flatcar serves as the support base for the entire machine, with an equipment base fixed to its upper surface. The equipment base is used to mount the gear frame of the tilting system. The bottom of the flatcar is equipped with a set of wheels, allowing it to move on a track. One end of the flatcar has an opening through which the smaller flatcar is inserted and moves horizontally. The smaller flatcar carries the transfer package to be processed, and its travel is limited by a flatcar reinforcement located inside the flatcar opening to ensure that the transfer package is accurately conveyed to the tilting station. The function of the flatcar reinforcement is to limit the travel of the smaller flatcar, ensuring that the transfer package is accurately conveyed to the tilting station, while also enhancing the structural strength of the flatcar opening to prevent local deformation caused by the weight of the transfer package or tilting vibration. The flatcar is also equipped with a height adjustment mechanism, which specifically uses four sets of hydraulic lifting cylinders symmetrically arranged at the four corners of the flatcar, powered by an integrated hydraulic pump station. The working principle is as follows: the PLC controls the electro-hydraulic proportional valve to adjust the oil intake of the four sets of lifting cylinders, and the magnetostrictive displacement sensor on the cylinder body provides real-time feedback of height data to achieve synchronous lifting of the four cylinders. It can adapt to various transfer bags with trunnion height within this range, so that the trunnion of the transfer bag is precisely aligned with the hook locking part in the flipping system.

[0010] Furthermore, the tilting system is a core functional module, including a drive unit fixed to the flatcar, a first gear set and a second gear set symmetrically arranged on the left and right sides of the flatcar with identical structures, and a tilting frame. The drive unit is a reducer, whose output shaft is connected to the drive gear; each gear set includes a drive gear, a first driven gear, a second driven gear, a third driven gear, and a ring gear; the transmission path is as follows: the reducer drives the drive gear to rotate, the drive gear meshes with the first driven gear, the first driven gear meshes with one side of the ring gear's tooth surface, the second driven gear meshes with the other side of the ring gear's tooth surface, and the second driven gear then meshes with the third driven gear, forming a multi-stage reduction transmission chain; the ring gear has a ring-shaped structure, its inner side is rigidly connected to the tilting frame by flange or welding, and its outer tooth surface simultaneously meshes with the first driven gear, the second driven gear, and the third driven gear, forming a multi-stage reduction transmission chain; the ring gear has a ring-shaped structure, its inner side is rigidly connected to the tilting frame by flange or welding, and its outer tooth surface simultaneously meshes with the first driven gear, the second driven gear, and the third driven gear. The gear and the third driven gear mesh to form a three-point meshing support structure, thereby driving the tilting frame to make continuous circular motion around the horizontal axis within the range of 0° to 180° under the action of the drive device, and achieving reliable locking at any angle through the self-locking of the reducer or an additional brake. Specifically, the drive device adopts a worm gear reducer, which uses its reverse self-locking characteristic to prevent the tilting frame from rotating when there is no power input; at the same time, an electro-disc brake is configured and installed at the output shaft end of the reducer. When the control system receives the angle locking command, the brake coil is energized to generate magnetic force to attract the friction disc, thereby achieving rapid braking and ensuring a stable and reliable locking state.

[0011] Specifically, the tilting frame is a frame-type steel structure, with a hook fixing component and a hydraulic cylinder fixing component on its inner side; the hook locking component is hinged to the hook fixing component by a pin, and its front end profile matches the structure of the transfer bag ear, used to lock the transfer bag trunnion; one end of the hook cylinder is fixed to the hydraulic cylinder fixing component by a pin, and the other end is hinged to the middle of the hook locking component by a pin; when the hook cylinder extends, it pushes the hook locking component to rotate upward around its hinge point, so that the front end of the hook engages with the transfer bag ear, completing the locking; when the hook cylinder retracts, the hook locking component rotates downward under the action of gravity or a return spring, releasing the transfer bag ear, realizing automatic unlocking.

[0012] Furthermore, to improve the synchronicity and structural rigidity of the flipping process, the first gear set and the second gear set are rigidly connected by a bracket connector, so that the gear sets on both sides move synchronously under the action of the drive device, avoiding uneven loading or twisting caused by unilateral force. At the same time, a guide groove is provided on the equipment base, which is arranged along the rotation trajectory of the ring gear. A guide plate is fixedly provided on the outer edge of the ring gear, which is embedded in the guide groove and can slide along the arc path of the guide groove. The guide groove applies radial and axial constraints to the guide plate to prevent the ring gear from swaying, axial movement, or radial runout during rotation, thereby ensuring the stability of the flipping frame operation and the repeatability of angle control.

[0013] Furthermore, the collection system includes a slag basin located at the front end of the flipping system. The slag basin is an open-top heat-resistant container with its opening facing the vertical projection area of ​​the slag falling when the transfer bag is flipped to 180°. The bottom of the slag basin is provided with a slag discharge port or a removable bottom plate to facilitate the periodic cleaning of accumulated steel slag or iron slag. The slag basin is made of high-temperature resistant cast iron or a composite structure of refractory materials to withstand the direct impact and heat radiation of high-temperature slag.

[0014] Furthermore, the protective system includes a flue gas collection hood surrounding the overturning operation area and a flue gas recovery pipe connected to the top of the flue gas collection hood; the flue gas collection hood is a semi-enclosed steel structure, made of 10mm thick high-temperature resistant steel plate Q345R, with a 50mm thick aluminum silicate fiber insulation layer on the inner wall; it has a transfer bag inlet / outlet channel on the front side, and the other three sides and the top are enclosed to block high-temperature slag splashes, limit heat radiation diffusion, and form a local negative pressure space; the flue gas recovery pipe is made of seamless steel pipe. The flue gas recovery pipe is connected to the pre-reserved interface on the top of the flue gas collection hood via a flange. The flange gasket is made of high-temperature resistant graphite composite gasket. A butterfly valve is installed between the flue gas recovery pipe and the external dust removal system for flow regulation to ensure that a local negative pressure environment of -50Pa to -100Pa is formed inside the flue gas collection hood. The lower end of the flue gas recovery pipe is connected to the internal cavity of the flue gas collection hood, and the upper end is connected to the external dust removal system or induced draft fan to extract the flue gas, dust and volatile gases generated during slag dumping and hot repair to the treatment device to prevent the deterioration of the working environment.

[0015] Specifically, the drive device of the flipping system adopts a geared motor with a brake. Its output torque is transmitted to the ring gear after being reduced by multiple gears, achieving low-speed, high-torque output. The reduction ratio is set according to the maximum load of the transfer bag and the flipping speed requirements to ensure a smooth and shock-free flipping process. The module, pressure angle, and tooth width of the ring gear and each driven gear are designed for heavy-load conditions, and the tooth surface is carburized and quenched to improve wear resistance and fatigue strength. The gear frame consists of four independent supports, which are used to install the driving gear, the first driven gear, the second driven gear, and the third driven gear, respectively. Each gear is supported in the corresponding gear frame by bearings, and the gear axes are parallel and coplanar to ensure meshing accuracy.

[0016] Furthermore, the flatcars are equipped with positioning pins or electromagnetic locking mechanisms to automatically lock the flatcar position after the transport package is in place, preventing displacement due to vibration during the flipping process; the height adjustment mechanism of the flatcar includes four sets of synchronous lifting hydraulic cylinders, which are respectively arranged at the four corners of the flatcar, and the height can be finely adjusted by proportional valve control, with an adjustment range covering 800mm to 1200mm to accommodate transport packages with different trunnion heights; the flatcar reinforcement is a detachable stop block, the position of which can be replaced or adjusted according to the travel requirements of the flatcar.

[0017] Furthermore, the hook locking component is forged from high-strength alloy steel, and its working surface is provided with anti-slip teeth or grooves to enhance the friction with the ears of the transport bag; the oil cylinder is a double-acting hydraulic cylinder, equipped with a pressure sensor and a displacement sensor, used to monitor the locking force and hook position in real time, and feed the signal back to the control system to realize closed-loop control; when it is detected that the locking is not in place or the transport bag is loose, the system automatically pauses the flipping action and issues an alarm.

[0018] Furthermore, a reinforcing rib is provided at the connection between the tilting frame and the ring gear to improve the overall rigidity; an auxiliary support roller is also provided on the inner side of the tilting frame, which contacts the bottom of the transfer bag when the transfer bag is tilted to nearly 180° to share part of the load and prevent the risk of overturning caused by the shift of the center of gravity; a slag flow guide plate is provided above the collection box to guide the slag material to fall into the central area of ​​the collection box and avoid scattering to other parts of the equipment.

[0019] Through the above structural design, the present invention achieves the following technical effects:

[0020] 1. This invention utilizes a multi-stage gear transmission and a three-point meshing structure of a ring gear to enable the tilting frame to continuously tilt within the range of 0° to 180°, and to achieve mechanical locking at any angle through self-locking of the reducer or braking device, thus meeting the requirements for thorough slag removal and multi-position hot repair.

[0021] 2. This invention uses a hydraulically driven hook locking component to automatically lock with the ear of the transfer bag, and combines the guide groove and guide plate to limit the radial and axial movement of the ring gear, ensuring that the transfer bag has no relative displacement and runs smoothly during the flipping process;

[0022] 3. This invention achieves rapid adaptation and precise positioning of transport packages of different specifications through a height-adjustable flatcar and a small flatcar with limiters;

[0023] 4. This invention effectively isolates high-temperature splashes and discharges smoke and dust through a semi-enclosed negative pressure working space formed by a protective cover and an exhaust pipe, thereby improving the working environment;

[0024] 5. This invention integrates slag dumping and hot repair functions into the same equipment, eliminating intermediate transfer links, shortening the operation cycle, and improving equipment utilization.

[0025] The coordinated operation of the above systems gives the present invention the technical advantages of compact structure, reliable operation, strong compatibility, safety and environmental protection, making it suitable for slag dumping and hot repair maintenance of various liquid metal transfer packages in the metallurgical industry.

[0033] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Figure 1-5 As shown, the present invention provides a liquid metal transfer ladle slag removal and hot repair machine, the overall structure of which includes four major functional modules: a conveying system, a tilting system, a collection system, and a protection system. The conveying system mainly consists of a flatcar 1 and a small flatcar 2; the tilting system includes a drive unit, a first gear set 3, a second gear set 4, a tilting frame 5, and related connecting and locking mechanisms; the collection system mainly includes a slag basin 14 located at the front end of the tilting path; and the protection system consists of a flue gas collection hood 21 and a flue gas recovery pipe 22.

[0034] In actual operation, the steel ladle or iron ladle (collectively referred to as transfer bag 23) after the casting operation is completed is first placed on the flatcar 2. The flatcar 2 is a movable carrying platform with rollers at the bottom, which can slide horizontally inside the flatcar 1. The flatcar 1 has an opening at one end, through which the flatcar 2 is inserted into the flatcar 1 and precisely positioned under the constraint of its flatcar reinforcement 20. The function of the flatcar reinforcement 20 is to limit the movement of the flatcar, ensure that the transfer bag is accurately transported to the turning station, and at the same time enhance the structural strength of the opening of the flatcar to prevent local deformation caused by the weight of the transfer bag or the vibration of the turning. The flatcar reinforcement 20 is a detachable structure, and its installation position can be adjusted according to the length of the transfer bag of different specifications, thereby ensuring that the ears of the transfer bag 23 are accurately aligned with the hook locking part 13 in the turning system. Meanwhile, the flatcar 1 is equipped with a height adjustment mechanism (not shown in the figure), which specifically adopts four sets of hydraulic lifting cylinders symmetrically arranged at the four corners of the flatcar. Each set of lifting cylinders has a cylinder diameter of 125mm and a stroke of 400mm, and is powered by an integrated hydraulic pump station. The oil intake of the four sets of lifting cylinders is adjusted by the electro-hydraulic proportional valve controlled by the PLC. Combined with the real-time feedback of height data by the magnetostrictive displacement sensor on the cylinder body, the four cylinders can be raised and lowered synchronously. The adjustment range covers 800mm to 1200mm, which can be adapted to various transfer bags with trunnion height within this range, ensuring that the center line of the trunnion of the transfer bag 23 and the locking position of the hook locking part 13 are on the same horizontal plane.

[0035] Once the transfer bag 23 is in place, the equipment control system is activated, and the hook cylinder 24 begins to operate. One end of the hook cylinder 24 is fixed to the cylinder fixing member 12 inside the tilting frame 5, and the other end is hinged to the middle of the hook locking member 13. When the hook cylinder 24 extends, it pushes the hook locking member 13 to rotate upward around the hinge point between itself and the hook fixing member 11, causing its front end profile to engage with the ear of the transfer bag 23, completing the automatic locking. The hook locking member 13 is forged from high-strength alloy steel, and its working surface has anti-slip teeth to enhance friction and prevent slippage. At the same time, the hook cylinder 24 is equipped with a pressure sensor and a displacement sensor to provide real-time feedback on the locking status. If incomplete locking is detected, the system will automatically pause subsequent tilting operations and issue an alarm signal.

[0036] After the transfer package 23 is locked, the flipping system drive device (not shown in the figure) is activated. This drive device is a reducer with a brake, and its output shaft is connected to the drive gear 6. The drive gear 6 meshes with the first driven gear 7, which in turn meshes with one side of the outer tooth surface of the ring gear 10. Simultaneously, the other side of the outer tooth surface of the ring gear 10 meshes with the second driven gear 8, which in turn meshes with the third driven gear 9, forming a multi-stage reduction transmission chain. This transmission path allows power to be output from the reducer and then sequentially pass through the drive gear → the first driven gear → the ring gear. At the same time, the second and third driven gears directly mesh with the ring gear, forming a three-point support structure. Since the inner side of the ring gear 10 is rigidly connected to the flipping frame 5, the flipping frame 5 moves in a circular motion around the horizontal axis along with the ring gear 10, achieving continuous flipping within the range of 0° to 180°.

[0037] To ensure synchronized flipping on both sides and avoid uneven loading, the first gear set 3 and the second gear set 4 are rigidly connected by a bracket connector 15. Furthermore, a guide groove 18 is provided on the equipment base 16, and a guide plate 19 is fixedly connected to the outer edge of the ring gear 10. The guide plate 19 is embedded in the guide groove 18 and can slide along its arc-shaped trajectory. The guide groove 18 applies radial and axial constraints to the guide plate 19, effectively preventing the ring gear 10 from wobbling, axial movement, or radial runout during rotation, thereby ensuring the smoothness of the flipping process and the accuracy of angle control. Each gear is mounted on an independent gear carrier 17, which is fixed to the equipment base 16, ensuring that the gear axes are parallel and coplanar, improving meshing accuracy. All gear tooth surfaces are carburized and quenched to meet the requirements of wear resistance and fatigue strength under heavy-load conditions.

[0038] During the slag dumping operation, the tilting frame 5 rotates the transfer bag 23 180°, so that the bag opening faces downwards. The remaining slag is then poured into the slag basin 14 located directly below the tilting path under gravity. The slag basin 14 is an open-top heat-resistant container made of high-temperature cast iron or a composite structure of refractory materials, capable of withstanding direct impact from high-temperature slag. A slag flow guide plate is installed above the slag basin 14 to guide the slag to fall into its central area, preventing splashing and scattering. The bottom of the slag basin 14 has a slag discharge port or a removable bottom plate for easy periodic cleaning of accumulated slag.

[0039] During hot repair operations, operators can stop the tilting frame 5 at any angle (such as 45°, 90°, etc.) using the control system, according to the required viewing angle of the repaired area. At this position, mechanical locking is achieved through the reverse self-locking characteristic of the worm gear reducer and the electro-disc brake at the output shaft end; the brake ensures the stability of the transport package 23 without shaking during hot repair. The inner side of the tilting frame 5 is also equipped with auxiliary support rollers, which contact the bottom of the transport package 23 when approaching the 180° tilting position, sharing some of the load and preventing the risk of equipment tipping over due to a shift in the center of gravity.

[0040] Throughout the entire operation, the protective system operates synchronously. The flue gas collection hood 21 is located around the outer perimeter of the turning operation area. It is made of 10mm thick high-temperature resistant steel plate Q345R, with a 50mm thick aluminum silicate fiber insulation layer on the inner wall, forming a semi-enclosed working space, with only a front passage for the transfer bag 23 to enter and exit. The flue gas collection hood 21 has an IP54 protection rating, effectively blocking high-temperature slag splashes and limiting heat radiation diffusion. The flue gas recovery pipe 22 is made of seamless steel pipe and connects to the pre-reserved interface at the top of the flue gas collection hood 21 via a flange (the flange gasket is a high-temperature resistant graphite composite gasket). The upper end of the flue gas recovery pipe connects to an external dust removal system, ensuring a local negative pressure environment of -50Pa to -100Pa within the flue gas collection hood. This extracts the flue gas, dust, and volatile gases generated during slag dumping and hot repair to the treatment device, preventing pollution of the working environment.

[0041] Furthermore, a positioning pin or electromagnetic locking mechanism is provided between the flatcar 2 and the flatcar 1, which automatically locks the position of the flatcar 2 after the transfer package 23 is in place, preventing displacement due to vibration during the flipping process. The control system integrates a PLC and a human-machine interface, supports manual / automatic mode switching, and allows operators to set the flipping angle, speed, and dwell time via the touch screen to achieve intelligent control.

[0042] In summary, this invention, through its structural design and operational process, achieves integrated and efficient operation of slag removal and hot repair of liquid metal transfer ladles. The equipment features a large-angle tilting capability, arbitrary angle locking function, automatic locking mechanism, height-adjustable conveying platform, and a comprehensive dust isolation system. It solves the problems of low tilting accuracy, poor safety, functional separation, and insufficient versatility in existing technologies, significantly improving the safety, efficiency, and automation level of transfer ladle maintenance operations in the metallurgical industry.

Moreover, these devices have been widely used in various fields, and those skilled in the art are familiar with their usage methods, so there is no technical threshold.

Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
