Description

Technical Field

[0001] This utility model belongs to the field of casting technology, specifically relating to a quick-change tundish slag discharge hopper device for continuous casting. Background Technology

[0002] During the continuous casting process, a single tundish line needs to pour multiple heats of molten steel. Generally, in the later stages of tundish line use, the slag layer floating on the surface of the molten steel in the tundish may reach a thickness of more than 200mm. In the later stages of continuous casting, the steel slag produced by the ladle will flow into the tundish along with the molten steel, causing contamination of the molten steel. In order to ensure continuous production of the continuous casting machine and to ensure the quality of molten steel pouring, slag removal operation is required in the tundish during the pouring process.

[0003] Currently, in continuous casting, the quick-change tundish slag discharge hopper device faces several challenges. When production abnormalities occur or slag discharge is required, the slag discharge hopper cannot be changed quickly during production. Replacement can only be done by using a crane after the casting machine is stopped. The inability to change the slag discharge hopper in a timely manner prevents impurities in the tundish from being discharged quickly, affecting normal slag discharge during production and reducing equipment efficiency. Furthermore, changing the slag discharge hopper during casting machine production breaks increases the workload for operators. Utility Model Content

[0004] The purpose of this invention is to provide a quick-change tundish slag discharge hopper device for continuous casting, so as to solve the problem mentioned in the background art that the slag discharge hopper cannot be quickly changed when different slag discharge requirements are encountered, and the transport track must be adjusted when the operator changes it.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A quick-change tundish slag discharge hopper device for continuous casting includes a base plate, a disassembly assembly inside the base plate, a conveying hopper connected to the top of the base plate via the disassembly assembly, a moving assembly at the bottom of the base plate, a track slidably connected to the base plate via the moving assembly, and an operation box on one outer wall of the base plate.

[0007] Furthermore, the disassembly assembly includes a sliding groove, two of which are formed on the upper surface of the base plate. The bottom inner wall of the sliding groove is provided with an inclined block. The two ends of the inner side wall of the sliding groove are respectively provided with a first slot and a second slot. A first insert rod is inserted into the first slot, and a second insert rod is inserted into the second slot. Several limiting blocks are provided on opposite sides of the outer wall of the base plate. Each limiting block is provided with a limiting rod, and the limiting rod is inserted into one outer end of the first insert rod and the second insert rod respectively.

[0008] Furthermore, the moving component includes a fixed block, which is fixedly connected to the bottom of the base plate. A rotary motor is fixedly connected inside the fixed block. A first connecting plate is fixedly connected to the transmission end of the rotary motor. A belt is movably connected to the side surface of the first connecting plate. A second connecting plate is movably connected to the side of the belt away from the first connecting plate.

[0009] Furthermore, a rotating shaft is fixedly connected inside the second connecting plate, and a power wheel is fixedly connected to both ends of the rotating shaft. An auxiliary wheel is fixedly connected to the bottom of the base plate at the other end of the power wheel. A fixed tube is fixedly connected to the side surface of the rotating shaft, and a rotating shaft is fixedly connected to the top of the fixed tube. The other end of the rotating shaft is movably connected to the base plate.

[0010] Furthermore, each of the two sides of the bucket is equipped with a traction hook, and each traction hook is connected to a manual crank via a rope. The manual crank is located on both sides of the base plate.

[0011] Furthermore, two sliders are fixedly connected to the bottom of the bucket. The sliders are slidably disposed in the groove. Two matching holes are opened inside the sliders, and the first and second insert rods are respectively inserted into the matching holes.

[0012] The beneficial effects of this utility model are:

[0013] 1. By adding a disassembly assembly, the bucket is connected to the base plate via a slider and a matching hole. An inclined block within the chute forms a ramp that prevents lateral movement of the bucket after the slider is installed. The first insert rod is inserted into the first slot and the matching hole, and the second insert rod is inserted into the second slot and the matching hole to fix the bucket's front and rear. A limiting rod is then inserted into the outer end of the second and first insert rods. The limiting block prevents the limiting rod from rotating. The ramp and two insert rods not only fix the bucket but also facilitate disassembly, allowing for the replacement of buckets of different sizes. This solves the problem of complex disassembly work for operators when replacing slag discharge buckets.

[0014] 2. By adding a moving component and a fixed block to protect the rotating motor, the rotating motor drives the first connecting plate to rotate. The first connecting plate drives the second connecting plate to rotate via a belt. The second connecting plate drives the power wheel connected to the rotating shaft to rotate. The fixed tube restricts the power wheel, and the rotating shaft helps the power wheel to rotate within the limits of the track. The auxiliary wheel provides stability, and the driving force is improved by hinged rotation. This solves the problem of not being able to quickly change the slag discharge bucket when encountering different slag discharge requirements. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] like Figure 1-5 As shown, a quick-change tundish slag discharge hopper device for continuous casting includes a base plate 1, a disassembly assembly 2 is provided inside the base plate 1, a conveying hopper 4 is connected to the top of the base plate 1 through the disassembly assembly 2, a moving assembly 3 is provided at the bottom of the base plate 1, a track 6 is slidably connected to the base plate 1 through the moving assembly 3, and an operation box 7 is provided on one outer wall of the base plate 1.

[0023] Specifically, the disassembly assembly 2 includes a slide 201. Two slides 201 are formed on the upper surface of the base plate 1. An inclined block 202 is provided on the bottom inner wall of the slide 201 to prevent the bucket 4 from moving laterally. A first slot 203 and a second slot 204 are respectively formed at both ends of the inner side wall of the slide 201. A first insert rod 205 is inserted into the first slot 203, and a second insert rod 206 is inserted into the second slot 204. Several limiting blocks 207 are provided on the opposite sides of the outer wall of the base plate 1. Each limiting block 207 is provided with a limiting rod 208. The limiting block 7 can prevent the limiting rod 8 from rotating, and the limiting rod 208 is respectively inserted into one outer end of the first insert rod 205 and the second insert rod 206.

[0024] Specifically, the moving component 3 includes a fixed block 301, which is fixedly connected to the bottom of the base plate 1. A rotary motor 302 is fixedly connected inside the fixed block 301. A first connecting plate 303 is fixedly connected to the transmission end of the rotary motor 302. A belt 304 is movably connected to the side surface of the first connecting plate 303. A second connecting plate 305 is movably connected to the side of the belt 304 away from the first connecting plate 303.

[0025] Specifically, a rotating shaft 306 is fixedly connected inside the second connecting plate 305. Both ends of the rotating shaft 306 are fixedly connected to a power wheel 307. An auxiliary wheel 310 is fixedly connected to the bottom of the base plate 1 at the other end of the power wheel 307. The auxiliary wheel 310 provides stability. A fixing tube 308 is fixedly connected to the side surface of the rotating shaft 306. The fixing tube 308 restricts the power wheel 307. A rotating shaft 309 is fixedly connected to the top of the fixing tube 308. The other end of the rotating shaft 309 is movably connected to the base plate 1. The rotating shaft 309 can help the power wheel 307 rotate in a limited manner on the track 6.

[0026] Specifically, each of the two sides of the bucket 4 is equipped with a traction hook 5, and each traction hook 5 is connected to a manual crank 11 by a rope. The manual crank 11 is placed on both sides of the base plate 1. When the rotary motor 302 malfunctions, the device can be manually driven by the manual crank 11 to reduce the risk.

[0027] Specifically, the bottom of the bucket 4 is fixedly connected with two sliders 209. The sliders 209 are slidably disposed in the slide groove 201. Two holes 210 are opened inside the sliders 209. The first insertion rod 205 and the second insertion rod 206 are respectively inserted into the holes 210.

[0028] In practical application, firstly, the bottom slider 209 of the bucket 4 is aligned with the groove 201 on the top of the base plate 1 and pushed longitudinally along the groove 201. When the slider 209 moves to the end of the groove 201, the ramp structure formed by the bottom inclined block 202 restricts the lateral displacement of the slider 209, ensuring the initial positioning of the bucket 4. The first insertion rod 205 and the second insertion rod 206 are respectively inserted into the first slot 203, the second slot 204 and the matching hole 210. The limiting rod 208 passes through the outer ends of the first insertion rod 205 and the second insertion rod 206 and is locked by the limiting block 207, forming a secondary fixation of the bucket 4.

[0029] During continuous casting, when slag is poured into the tundish 8 along with molten steel, the tundish pours the molten steel into the bottom intermediate tank 9. The intermediate tank 9 discharges the slag through the funnel 10 fixedly connected to its side. At this time, the device starts the rotary motor 302 through the operation box 7, which further drives the first connecting plate 303 to rotate. The rotation is transmitted to the second connecting plate 305 through the belt 304, which further drives the power wheels 307 at both ends of the rotating shaft 306 to move along the track 6. The fixed pipe 308 and the rotating shaft 309 constrain the direction of the power wheels 307. The auxiliary wheel 310 provides balance support, so that the device moves along the track 6 to the funnel 10, specifically with the hopper 4 below the funnel 10, and then the slag discharge begins.

[0030] When it is necessary to replace the hopper 4, pull out the limit bar 208, and pull out the first insert rod 205 and the second insert rod 206 respectively, so that the slider 209 exits along the slide groove 201; the new hopper 4 can be reinstalled according to the above steps. During the replacement process, there is no need to adjust the moving component 3, the track 6 or the operation box 7, which achieves the technical effect of quickly replacing the slag discharge hopper 4.

[0031] Furthermore, if the rotary motor 302 malfunctions, the rope can be attached to the traction hooks 5 on both sides of the bucket 4, and the bucket can be moved along the track 6 by manually cranking the lever 11, thus achieving the same technical effect.
