Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of converter steelmaking, and particularly relates to a converter automatic tapping device and a converter system. BACKGROUND

[0002] Converter steelmaking is a process of using hot metal, scrap steel and ferroalloy as main raw materials, without external energy, to complete the steelmaking process in a converter by means of physical heat of the molten iron and heat generated by chemical reactions between components of the molten iron. In the converter tapping process, the eyes of a swing operator are mainly relied on to observe the conditions of a large furnace mouth, a tapping hole, a chute position, a trolley position and a ladle liquid surface, and relevant equipment is operated according to the experience of the swing operator. Different swing operators are different in experience level, knowledge reserve and professional quality, which not only brings difficulties to high-quality and high-efficiency production organization, but also causes the average tapping level to be unable to break through the bottleneck.

[0003] However, the existing converter generally has the problem of inconvenient precise control of the overturning angle during the swing tapping. Because the content of impurity elements in the molten steel needs to be as low as possible. In the process of pouring the molten steel from the converter into a molten steel tank at the end of the converter steelmaking, the slag sometimes flows into the molten steel tank together with the molten steel (i.e., slagging in the converter tapping), which affects the cleanliness of the molten steel. At present, strictly controlling the tapping process is an important means to avoid slagging in the converter tapping.

[0004] In addition, when the converter is seriously aged after long-time use and cannot meet the normal production requirements, the converter needs to be updated and removed. The conventional converter removal construction method is to remove all components such as bearing seats, speed reducers and aprons, leaving only the furnace shell and the trunnion ring. After the heat insulation plates on both sides of the furnace bottom are removed, the hinge connection between the trunnion ring and the converter is disconnected, and then the components are hoisted one by one by a travelling crane. The installation process is performed in reverse. The whole dismounting and installation process needs at least 15 days, which makes the dismounting and installation efficiency of the converter low and affects the production efficiency of the steelmaking.

[0005] A patent with publication number CN112961957A discloses an auxiliary rotating device of a steelmaking converter and a use method, which comprises a support for supporting the converter and a driving mechanism; the driving mechanism comprises a first connecting rod hinged to the converter and linearly moving at the other end, and the first connecting rod is provided with a slot; a first support is arranged on one side of the first connecting rod, and the first support is provided with a sliding groove; a first sliding block is slidingly arranged in the sliding groove; a rotating rod is arranged on the first sliding block and penetrates the slot; a spring is arranged in the sliding groove and connected to the first sliding block, and the other end is connected to the bottom of the sliding groove; a first telescopic piece is arranged on the top of the first support and above the sliding groove, and the first telescopic piece has a first pushing end abutting against the first sliding block; a second telescopic piece has a second pushing end connected with the first connecting rod. The above-mentioned steelmaking converter uses a mechanical structure to control the rotation of the converter, which cannot accurately control the rotation angle of the converter, and cannot position the converter at any angle, and the installation and disassembly of the converter are not convenient, the construction period is long, and the problem proposed in the present application cannot be solved. SUMMARY

[0006] To solve the above technical problems, the present application provides a converter automatic tapping device and a converter system, which can flexibly adjust and accurately control the overturning angle of the converter, can stably position the converter at any angle, and can effectively avoid the speed of the tapping hole being too fast to discharge the steel slag, thereby improving the cleanliness of the molten steel.

[0007] To achieve the above-mentioned purposes, the technical scheme adopted by the present application to solve its technical problems is: the converter automatic tapping device comprises a supporting base, two rotating mechanisms are rotatably connected to the two sides of the supporting base, two groups of rotating mechanisms are detachably connected to the two sides of the converter body, and lifting locking mechanisms for locking the corresponding rotating mechanisms are further arranged on the two sides of the supporting base.

[0008] The supporting base is arranged in a U-shaped seat, vertical mounting plates are arranged at the two ends of the supporting base, mounting holes are oppositely arranged on the two vertical mounting plates, and the mounting holes are connected to the rotating mechanisms through bearings.

[0009] The rotating mechanism comprises a rotating disc assembly rotatably connected to one side of the supporting base, one end of the rotating disc assembly is detachably connected to the converter body, and the other end of the rotating disc assembly is connected to a power mechanism.

[0010] The power mechanism comprises a first motor fixed to the outer side of the supporting base, and the first motor is connected to the outer end of the rotating disc assembly through a speed reduction gear mechanism.

[0011] The first motor is provided with one, and the speed reduction gear mechanism comprises a driving gear fixedly connected to the output shaft of the first motor and a driven gear engaged with the driving gear.

[0012] The first motor is provided in two and symmetrically arranged on both sides of the turntable assembly. The reduction gear mechanism includes a driving gear fixedly connected to the output shafts of the two first motors and a driven gear meshing with the two driving gears.

[0013] The outer diameter of the driving gear is smaller than the outer diameter of the driven gear, and the driven gear is fixedly connected to the outer end of the turntable assembly via a disk.

[0014] The lifting and locking mechanism includes an electric slide rail installed on one side of the support base. A vertical plate is fixed on the slider of the electric slide rail, and an arc-shaped locking plate that is engaged with the driven gear is fixed on the top of the vertical plate.

[0015] The turntable assembly includes a turntable body connected to the power mechanism and a guide sliding assembly slidably connected thereto. The outer end of the guide sliding assembly is detachably connected to one side of the converter body.

[0016] The turntable body includes a connecting shaft section rotatably connected to one side of the support base. An annular mounting section integrally formed with the connecting shaft section is provided on the outer periphery of the middle part. Multiple guide cylinders are evenly distributed along the annular mounting section. A threaded hole is provided at the end of the connecting shaft section away from the power mechanism.

[0017] The guide sliding assembly includes a limiting slide plate, and multiple slide rods are evenly distributed along the circumference of the limiting slide plate. The multiple slide rods are guided and slidably connected in corresponding guide cylinders. A mounting post extending into the threaded hole is provided in the middle of the limiting slide plate. A second motor is embedded in the mounting post. An external threaded disc is installed on the output shaft of the second motor. The external threaded disc is threadedly connected to the threaded hole.

[0018] An anti-rotation sleeve is provided at one end of the guide sliding assembly away from the turntable body. Anti-rotation blocks are respectively provided on both sides of the converter body and are connected to the corresponding anti-rotation sleeves. The anti-rotation sleeves are fixedly connected to the anti-rotation blocks by multiple bolt assemblies.

[0019] A converter system includes the aforementioned automatic steel tapping device and a control panel, which is connected to the rotating mechanism and the lifting and locking mechanism via a PLC.

[0020] The beneficial effects of this invention are:

[0021] 1. This invention provides an automatic steel tapping device for a converter. The converter body is driven to rotate by two sets of rotating mechanisms. The rotating mechanisms are locked by a lifting and locking mechanism. The rotating mechanisms can flexibly adjust and precisely control the flipping angle of the converter. The lifting and locking mechanism can make the converter stably positioned at any angle. This can effectively prevent the steel tapping speed from being too fast and causing steel slag to be discharged, thus improving the cleanliness of the molten steel.

[0022] 2. The rotating mechanism of this invention includes a turntable assembly rotatably connected to one side of the support base. In this turntable assembly, one end of the turntable body is guided and slidably connected to a limiting slide plate. A second motor is embedded in the mounting post of the limiting slide plate that extends into the threaded hole of the turntable body. When the two second motors on both sides of the support base are activated, they drive the external threaded disc to rotate, thereby causing the external threaded disc to move axially along the threaded hole. This causes multiple sliding rods of the limiting slide plate to slide along the guide cylinder of the turntable body, allowing the two limiting slide plates to move relative to or towards each other. This allows the anti-rotation sleeves on the two limiting slide plates to engage or disengage with the anti-rotation blocks on the converter body, making the disassembly and installation of the converter quicker and more convenient, and improving the production efficiency of steelmaking.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] The existing technology has the following problems: First, during the process of pouring molten steel from the converter into the ladle, due to the inability to strictly control the converter angle, slag sometimes flows into the ladle along with the molten steel (i.e., slag is added during converter tapping), affecting the cleanliness of the molten steel. Second, after prolonged use, the converter needs to be disassembled and replaced due to equipment aging and other reasons. The entire disassembly and installation process of the converter takes at least 15 days, resulting in low disassembly and installation efficiency and affecting the production efficiency of steelmaking. To address the above problems, this invention provides an automatic converter tapping device and converter system, which will be described in detail in the following embodiments.

[0032] Example 1

[0033] like Figs. 1-3 As shown, this invention provides an automatic steel tapping device for a converter, including a support base 1. Rotating mechanisms 2 are rotatably connected to both sides of the support base 1. The two sets of rotating mechanisms 2 are detachably connected to both sides of the converter body 3. Lifting and locking mechanisms 4 are also provided on both sides of the support base 1 to lock the corresponding rotating mechanisms 2. This invention drives the converter body 3 to rotate through the two sets of rotating mechanisms 2, and locks the rotating mechanisms 2 through the lifting and locking mechanisms 4. The rotating mechanisms 2 allow for flexible adjustment and precise control of the converter's tilting angle, while the lifting and locking mechanisms 4 allow the converter to be stably positioned at any angle. This effectively prevents excessively fast steel tapping from the tapping spout, thus avoiding slag discharge and improving the cleanliness of the molten steel.

[0034] Specifically, the support base 1 is configured as a U-shaped base, and vertical mounting plates 11 are respectively provided at both ends of the support base 1. Mounting holes 12 are respectively provided on the two vertical mounting plates 11. The mounting holes 12 are connected to the rotating mechanism 2 through bearings, which ensures that the rotating mechanism 2 drives the converter body 3 to rotate smoothly.

[0035] Specifically, the rotating mechanism 2 includes a turntable assembly rotatably connected to one side of the support base 1. One end of the turntable assembly is detachably connected to the converter body 3, and the other end of the turntable assembly is connected to the power mechanism 23. The power mechanism 23 drives the turntable assembly to rotate, thereby driving the converter body 3 connected to the turntable assembly to rotate synchronously.

[0036] The power mechanism 23 includes a first motor 231 fixed to the outside of the support base 1. The first motor 231 is connected to the outer end of the turntable assembly through a reduction gear mechanism.

[0037] One first motor 231 can be provided. The reduction gear mechanism includes a driving gear 232 fixedly connected to the output shaft of the first motor 231 and a driven gear 233 meshing with it. The outer diameter of the driving gear 232 is smaller than the outer diameter of the driven gear 233. The driven gear 233 is fixedly connected to the outer end of the turntable assembly through a disc 234. When the first motor 231 is activated, it drives the driving gear 232 to rotate, thereby driving the turntable assembly to rotate through the driven gear 233, and the turntable assembly drives the converter body 3 to rotate. To further improve the driving force, two first motors 231 can be provided and symmetrically arranged on both sides of the turntable assembly. The reduction gear mechanism includes driving gears 232 fixedly connected to the output shafts of the two first motors 231 respectively and driven gears 233 meshing with the two driving gears 232. The two first motors 231 operate synchronously, driving the driven gears 233 to rotate through the two driving gears 232, thereby driving the converter body 3 to rotate through the turntable assembly. In both of the above cases, the outer diameter of the driving gear 232 is smaller than the outer diameter of the driven gear 233, which can reduce the rotation of the converter body 3 and achieve stable rotation of the converter body 3 so as to accurately control the rotation angle of the converter body 3.

[0038] Specifically, the lifting and locking mechanism 4 includes an electric slide rail 41 installed on one side of the support base 1. A vertical plate 43 is fixed on the slider 42 of the electric slide rail 41, and an arc-shaped locking plate 44 that engages with the driven gear 233 is fixed on the top of the vertical plate 43. When the converter body 3 rotates to the set angle, the converter body 3 stops rotating. At the same time, the electric slide rail 41 moves, causing the slider 42 to drive the vertical plate 43 to move upward, so that the arc-shaped locking plate 44 engages with the driven gear 233, which can further limit and fix the driven gear 233, and lock the turntable assembly, thereby ensuring that the converter body 3 is stably locked at any angle.

[0039] The working principle of the rotating mechanism 2 and the lifting and locking mechanism 4 in the above-mentioned automatic steel tapping device of the converter is as follows: The first motor 231 on both sides of the support base 1 is activated, driving the drive gear 232 to rotate, which in turn drives the turntable assembly through the driven gear 233, and the turntable assembly drives the converter body 3 to rotate. When the converter body 3 rotates to the set angle, the converter body 3 stops rotating. At the same time, the electric slide rail 41 is activated, causing the slider 42 to drive the vertical plate 43 to move upward, so that the arc-shaped clamping plate 44 meshes and engages with the driven gear 233, limiting and fixing the driven gear 233, and locking the turntable assembly, thereby ensuring that the converter body 3 is stably locked at any angle.

[0040] Example 2

[0041] like Figs. 1-3 As shown, based on Embodiment 1, the present invention provides a structure that facilitates the disassembly and installation of the converter body. Specifically, the turntable assembly includes a turntable body 21 connected to the power mechanism 23 and a guide sliding assembly 22 slidably connected thereto. The turntable body 21 and the guide sliding assembly 22 are anti-rotationally connected, and the outer end of the guide sliding assembly 22 is detachably connected to one side of the converter body 3. When the power mechanism 23 is activated, it drives the turntable body 21 to rotate, thereby driving the guide sliding assembly 22 to move synchronously, causing the guide sliding assembly 22 to drive the converter body 3 to rotate, ensuring the smooth rotation of the converter body 3. In addition, the guide sliding assembly 22 can slide along the turntable body 21 to move closer to or further away from the converter body 3, facilitating the disassembly and installation of the converter body 3.

[0042] Specifically, the turntable body 21 includes a connecting shaft section 211 rotatably connected to one side of the support base 1. An annular mounting section 212, integrally formed with the connecting shaft section 211, is provided on the outer periphery of its central portion. Multiple guide cylinders 213 are evenly distributed along the circumference of the annular mounting section 212. A threaded hole 214 is provided at the end of the connecting shaft section 211 furthest from the power mechanism 23. The guide sliding assembly 22 includes a limiting slide plate 221. Multiple slide rods 222 are evenly distributed along the circumference of the limiting slide plate 221, and the slide rods 222 are slidably connected to corresponding guide cylinders 213. A mounting post 223 extending into the threaded hole 214 is provided in the central portion of the limiting slide plate 221. A second motor 224 is embedded in the mounting post 223. An external threaded disc 225 is mounted on the output shaft of the second motor 224, and the external threaded disc 225 is threadedly connected to the threaded hole 214. The second motor 224 drives the external threaded disc 225 to rotate, causing the external threaded disc 225 to move along the axis of the threaded hole 214. This causes the second motor 224, together with the limiting slide 221, to move along the axis of the threaded hole 214. Multiple sliding rods 222 along the axis of the limiting slide 221 slide along their corresponding guide cylinders 213, guiding and limiting the sliding of the limiting slide 221. This allows for simultaneous control of the two limiting slides 221 to move closer together and connect to both sides of the converter body 3, which can then be secured with bolts. Similarly, the two limiting slides 221 can be simultaneously controlled to move further apart, facilitating the disassembly of the converter body 3.

[0043] Specifically, the guide sliding component 22 is fixed with an anti-rotation sleeve 226 at one end away from the turntable body 21. The anti-rotation sleeve 226 can be set as a polygonal sleeve or an irregular sleeve, etc. Its shape includes rectangle, square, irregular shape with multiple protrusions, etc. Anti-rotation blocks 31 are respectively arranged on both sides of the converter body 3 and connected to the corresponding anti-rotation sleeves 226. The anti-rotation sleeve 226 is fixedly connected to the anti-rotation block 31 by multiple bolt assemblies, which not only ensures that the power of the rotating mechanism 2 is reliably transmitted to the converter body 3, but also makes the installation and disassembly of the converter body 3 and the rotating mechanism 2 more convenient and quick.

[0044] The installation method of the converter body 3 is as follows: First, the converter body 3 is moved between the two rotating mechanisms 2 using hoisting equipment, so that the anti-rotation blocks 31 on both sides of the converter body 3 are opposite to the anti-rotation sleeves 226 on the two rotating mechanisms 2; then, the two second motors 224 on both sides of the support base 1 move in opposite directions synchronously, driving the corresponding external threaded discs 225 to rotate, thereby causing the external threaded discs 225 to move along the axial direction of the threaded hole 214, causing the second motors 224 together with the limiting slides 221 to move along the axial direction of the threaded hole 214, causing the multiple slide rods 222 of the limiting slides 221 to slide along the corresponding guide cylinders 213, synchronously controlling the two limiting slides 221 to move closer to each other; finally, the two anti-rotation sleeves 226 are sleeved and connected to the corresponding anti-rotation blocks 31, and the corresponding anti-rotation blocks 31 and anti-rotation sleeves 226 are fastened together by bolt assemblies.

[0045] Example 3

[0046] Based on Embodiment 1 and Embodiment 2, the present invention also provides a converter system, including the above-mentioned automatic steel tapping device for converter, and a control panel. The control panel is connected to the rotating mechanism 2 and the lifting and locking mechanism 4 via a PLC, thereby realizing automatic steel tapping of converter and quick assembly and disassembly of converter.

[0047] When steel needs to be tapped, the speed and rotation angle of the first motor 231 in the two rotating mechanisms 2 and the stroke of the electric slide rail 41 in the lifting and locking mechanism 4 are input to the control panel. The PLC controls the first motor 231 to move, driving the drive gear 232 to rotate, which in turn drives the turntable assembly through the driven gear 233. The turntable assembly drives the converter body 3 to rotate. When the converter body 3 rotates to the set angle, the converter body 3 stops rotating. At the same time, the electric slide rail 41 moves, causing the slider 42 to drive the vertical plate 43 to move upward by the set stroke, so that the arc-shaped clamping plate 44 meshes and engages with the driven gear 233, limiting and fixing the driven gear 233, and realizing the locking and positioning of the converter body 3.

[0048] When it is necessary to disassemble the converter body 3, after the bolt assembly is removed, the rotation speed and rotation time of the two second motors 224 in the two rotating mechanisms 2 are input to the control panel. The PLC controls the two second motors 224 to move, so that the second motors 224 drive the external threaded disc 225 to move along the axis of the threaded hole 214, and at the same time, the limit slide 221 moves along the axis of the threaded hole 214, so that the two limit slides 221 move away from each other until the set running time is reached. Then the anti-rotation block 31 on the converter body 3 is disengaged from the anti-rotation sleeve 226 of the turntable assembly, and the converter body 3 can be removed by the hoisting equipment. Similarly, when it is necessary to install the converter body 3, the rotation speed and rotation time of the two second motors 224 in the two rotating mechanisms 2 are input to the control panel. The PLC controls the two second motors 224 to move, so that the two limit slides 221 move closer to each other. After the set running time, the anti-rotation block 31 on the converter body 3 is fitted into the anti-rotation sleeve 226 of the replaced converter body 3, and the anti-rotation block 31 is connected to the anti-rotation sleeve 226 by bolt assembly.

[0049] In summary, this invention allows for flexible adjustment and precise control of the converter's tilting angle, enabling the converter to be stably positioned at any angle. It effectively prevents excessively fast tapping of steel from causing slag discharge, thus improving the cleanliness of the molten steel. Furthermore, it makes the disassembly and installation of the converter quicker and more convenient, thereby increasing the production efficiency of steelmaking.

[0050] The above description is merely an illustration of some principles of the present invention. This specification is not intended to limit the present invention to the specific structures and applicable scope shown. Therefore, all possible modifications and equivalents that may be used fall within the scope of the patent application of this invention.
