Abstract
Description
Technical Field
[0001] The invention relates to the technical field of continuous casting slag flushing, in particular to an inclined plate mechanism for a slag flushing groove of a continuous casting machine. Background Art
[0002] During the hot transport of ingots from the mold to the casting line or during their unloading, a large amount of slag is generated. During this transport process, most of this slag falls into the continuous casting machine foundation pit, where it flows along with the slag flushing water into the slag flushing ditch. It then collects in a vortex well at one end of the slag flushing ditch, where it is scooped up by a slag scooper and transferred to the slag pool for processing. The continuous casting slag flushing ditch is located within the cement foundation pit. Due to the unevenness of the sides and bottom of the cement foundation pit caused by long-term use, the slag flushing water is no longer effective in removing iron oxide from the slag.
[0003] A Chinese patent with the announcement number CN219900168U discloses a slag flushing device for a square billet continuous casting machine foundation pit, comprising a foundation pit, wherein the bottom plate of the foundation pit is configured as a slide plate with a certain slope, which is high at both ends and low in the middle. The lower end of the slide plate is connected to the slag flushing ditch. The side walls of the foundation pit are provided with inclined supports, which are used to support the conveyor track crossbeam. By improving the foundation pit bottom plate into a slide plate with a larger inclination angle, the self-fluidity of the oxide slag is increased. At the same time, by replacing the original intermediate foundation support of the conveyor track crossbeam with double inclined supports provided on the shear wall of the foundation pit side wall, the slide plate is smooth and unobstructed, and there is no obstruction during slag flushing. There is no dead angle for slag flushing, and efficient online slag flushing can be achieved without stopping the machine for special repairs and slag cleaning, thereby improving the operating efficiency of the continuous casting machine.
[0004] In the current existing technology, the bottom end of the slide is fixedly connected to the slag flushing ditch, so the angle between the slide and the slag flushing ditch is fixed. However, if the amount of iron oxide accumulated is too large, the slide may not be able to divert the flow in time, resulting in local accumulation on the surface of the slide, or even encountering large pieces of iron oxide agglomerates, which may cause obstruction and prevent smooth slag flushing.
[0005] To this end, the present invention provides an inclined plate mechanism for a slag flushing groove of a continuous casting machine. Summary of the Invention

DETAILED DESCRIPTION
[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.
[0032] See also Figure 1 - Figure 8 The present invention provides an inclined plate mechanism for a slag ditch of a continuous casting machine, comprising a slag ditch body 1, wherein two connecting seats 12 are symmetrically fixed to the side walls of the slag ditch body 1; an inclined flow plate 21 is provided above the connecting seats 12, and two connecting blocks 121 are fixed to the bottom of the inclined flow plate 21, and the two connecting blocks 121 on the same side are rotatably connected to the connecting seat 12 through a rotating shaft; a slide rail 132 is fixed to the bottom of the inclined flow plate 21, and a slider 133 is slidably connected to the slide rail 132; a side plate 13 is fixed to the side wall of the connecting seat 12, and an oil cylinder 131 is fixed to the side plate 13, and the output end of the oil cylinder 131 is rotatably connected to the slider 133 through a pin shaft; water level gauges 11 are installed on the inner walls of both ends of the slag ditch body 1, and a cleaning mechanism is provided inside the slag ditch body 1, and the water level gauges 11 are electrically connected to the cleaning mechanisms respectively.
[0033] A large amount of slag is generated during the hot delivery of the ingot from the crystallizer to the casting line or during the delivery process. During the transportation of the ingot, most of the slag falls into the continuous casting machine foundation pit, flows into the slag flushing ditch along with the slag flushing water, and then gathers into the vortex well at one end of the slag flushing ditch. The slag is then scooped up by the slag scooper and transferred to the slag pool for treatment. The continuous casting slag flushing ditch is located in the cement foundation pit. Due to the aging of the sides and bottom of the cement foundation pit after long-term use, the slag flushing water can no longer effectively remove the iron oxide.
[0034] When the inclined flow plate 21 and the slag flushing ditch body 1 provided by the present invention are used, the inclined flow plate 21 is installed above the slag flushing ditch body 1 and is provided with a certain slope to ensure that after the iron oxide falls on the inclined flow plate 21, it is flushed into the slag flushing ditch body 1 in the middle of the inclined flow plate 21 by the secondary cold water in production. Since slopes are provided on both sides and a groove-shaped arc surface is provided on the bottom, the impact area of the slag flushing water is reduced, the water column is concentrated, and the impact force is increased. In addition, the inclined flow plates 21 on both sides are welded and polished to make the surface smooth and not easy to accumulate iron oxide, which can ensure that the iron oxide is washed clean and reduce the iron oxide. The cleaning difficulty is improved, and the cost of cleaning iron oxide is reduced. The secondary cold water used in production is used to directly flush and clean the iron oxide, which not only can directly enter the slag flushing groove body 1 for cleaning, but also helps to cool the area above the inclined flow plate 21, thereby extending the service life of the inclined flow plate 21. When the slag oxide is large or accumulated on the inclined flow plate 21, it is necessary to open the oil cylinder 131, and the output end of the oil cylinder 131 drives the slider 133 to move. During the movement, the slider 133 slides on the slide rail 132, thereby pushing the inclined flow plate 21 to rotate upward around the rotating axis.
[0035] The water level meter 11 is used to monitor whether there is obvious water level change at both ends of the slag flushing ditch body 1. If the difference between the two water level meters 11 is higher than the set threshold, the cleaning mechanism is controlled to open through the control program to clean the oxidized slag in the slag flushing ditch body 1.
[0036] Further, if Figure 2 As shown, the bottom of the slag flushing ditch body 1 is set as a groove-shaped arc surface, and arc plates are fixed to the tops of both ends of the slag flushing ditch body 1, and the arc plates are bent toward the inside of the slag flushing ditch body 1.
[0037] When the slag flushing ditch body 1 provided by the present invention is in use, the bottom of the slag flushing ditch body 1 is set to a groove-shaped arc surface, so that the impact area of the slag flushing water is reduced, the water column is concentrated, and the impact force is increased; arc plates are fixedly connected to the tops of both ends of the slag flushing ditch body 1, and the arc plates are bent toward the inside of the slag flushing ditch body 1 to prevent oxidized slag from splashing out from the gap between the inclined flow plate 21 and the slag flushing ditch body 1 during the slag flushing process.
[0038] Further, if Figure 2 and Figure 3 As shown, the top of the inclined flow plate 21 is fixedly connected with a protective plate 2, and the protective plate 2 is made of refractory material; the inclined flow plate 21 is made of metal; one end of the inclined flow plate 21 is provided with a slot 22; the other end of the inclined flow plate 21 is fixedly connected with an insert plate 23, and the insert plate 23 is plugged into the slot 22.
[0039] When the inclined flow plate 21 provided by the present invention is in use, it is welded and polished to make the surface smooth and not easy to accumulate iron oxide, which can ensure that the iron oxide is rinsed clean and reduce the difficulty of cleaning the iron oxide; the protective plate 2 is made of refractory material, and the inclined flow plate 21 is made of metal material to improve the thermal shock resistance and impact resistance.
[0040] Further, if Figure 1 and Figure 4 As shown, cold water tanks 3 are provided on both sides of the slag flushing ditch body 1, and two fixed plates 31 are fixedly connected to the top of the cold water tank 3. A reciprocating screw rod 312 is rotatably connected between the two fixed plates 31 through bearings, and a movable seat 313 is threadedly connected to the reciprocating screw rod 312; two guide rods 311 are fixed between the two fixed plates 31, and the movable seat 313 is slidably connected to the two guide rods 311; an exhaust hood 314 is installed at one end of the movable seat 313 close to the slag flushing ditch body 1, and an exhaust fan 315 is installed in the exhaust hood 314; a first motor 316 is provided at one end of the reciprocating screw rod 312.
[0041] When the exhaust fan 315 provided by the present invention is in use, high-temperature iron oxide falls on the protective plate 2, and a large amount of white smoke is generated by flushing with cold water. The white smoke is mainly water vapor and may contain trace iron oxide particles or dust, but no toxic gas. However, the accumulation of steam may cause excessive humidity, accelerate equipment corrosion or affect the surrounding environment. A large amount of steam may affect the operating field of view and increase the risk of slipping; therefore, it is necessary to turn on the first motor 316, and drive the reciprocating screw 312 to rotate through the output shaft of the first motor 316. The reciprocating screw 312 drives the movable seat 313 to move during the rotation process. The movable seat 313 drives the exhaust hood 314 and the exhaust fan 315 to move during the movement, which is used to accelerate the discharge of water vapor and maintain the humidity conditions in the workshop.
[0042] Further, if Figure 4 and Figure 5 As shown, the cleaning mechanism includes a cross bar 32 fixed between two movable seats 313, and a scraper 321 is slidably connected to the cross bar 32, and the bottom of the scraper 321 is in contact with the bottom of the slag flushing ditch body 1; the bottom of the scraper 321 is provided with a lifting mechanism.
[0043] When the cleaning mechanism provided by the present invention is in use, when cleaning is required, the scraper 321 is lowered by the lifting mechanism to fit the bottom of the slag flushing ditch body 1; then during the movement of the movable seat 313, the movable seat 313 drives the cross bar 32 to move, and the cross bar 32 drives the scraper 321 to move, and the scraper 321 is used to push out the oxidized slag in the slag flushing ditch body 1 for cleaning.
[0044] Further, if Figure 5As shown, the lifting mechanism includes a lifting plate 322 fixedly connected to the top of the scraper 321; the top of the cross bar 32 is fixedly connected to a fixed seat 323, and a threaded rod 325 is rotatably connected between the fixed seat 323 and the cross plate through a bearing; the threaded rod 325 is threadedly connected to the lifting plate 322, and two sliding rods 326 are fixedly connected between the fixed seat 323 and the cross plate; the lifting plate 322 is slidably connected to the two sliding rods 326; the top of the fixed seat 323 is fixedly connected to a second motor 324, and the output shaft of the second motor 324 is fixedly connected to the top of the threaded rod 325.
[0045] When the lifting mechanism provided by the present invention is in use, the water level gauge 11 is used to monitor whether there is an obvious water level change at both ends of the slag flushing ditch body 1. If the difference between the two water level gauges 11 is higher than the set threshold value, the second motor 324 is controlled by the control program, and the threaded rod 325 is driven to rotate by the second motor 324, and the lifting plate 322 is driven to move up and down by the threaded rod 325, and the scraper 321 is driven to move up and down by the lifting plate 322. When cleaning is required, the scraper 321 is driven to descend and fit into the bottom inner wall of the slag flushing ditch body 1; when cleaning is not required, the scraper 321 is driven to rise away from the slag flushing ditch body 1, thereby reducing the wear of the scraper 321.
[0046] Further, if Figure 5 and Figure 6 As shown, two protective boxes 33 are symmetrically fixed to the bottom of the crossbar 32, the top inner walls of the protective boxes 33 are fixed with electric telescopic rods 335, and the output ends of the electric telescopic rods 335 are fixed with probes 336; a blocking mechanism is provided at the bottom of the protective box 33.
[0047] When in use, the probe 336 provided by the present invention is used to monitor the wear thickness of the surface of the protective plate 2 to prevent perforation or local failure. When monitoring is required, the blockage of the bottom of the protective box 33 is released by opening the blocking mechanism, and then the electric telescopic rod 335 is turned on. The electric telescopic rod 335 drives the probe 336 downward through the output end, which is convenient for observing the wear condition of the surface of the protective plate 2 and timely feeding back the wear condition to the control program, so that the control program can issue an alarm reminder.
[0048] Further, if Figure 5 As shown, the blocking mechanism includes two blocking plates 331 slidably connected to the bottom of the protective box 33; a connecting frame 332 is fixedly connected to the outer walls of the two blocking plates 331; an L-shaped plate 333 is slidably connected to one side of the scraper 321, and a first electric push rod 334 is fixedly connected to the top of the L-shaped plate 333; the output end of the first electric push rod 334 is fixedly connected to the connecting frame 332.
[0049] When the sealing mechanism provided by the present invention is in use and sealing is required, the first electric push rod 334 is turned on, and the connecting frame 332 is driven to move through the output end of the first electric push rod 334, and the sealing plate 331 is driven to move through the connecting frame 332, and the sealing plate 331 slides on the bottom of the protective box 33 and seals the protective box 33 tightly, reducing the impact of water vapor on the probe 336. When detection is required, the connecting frame 332 is driven to move outward through the output end of the first electric push rod 334, and the sealing plate 331 is driven to move outward through the connecting frame 332, and the sealing plate 331 leaves the protective box 33 to release the blockage.
[0050] Further, if Figure 7 As shown, the cold water tank 3 is connected to a plurality of water spray pipes 34 on one side close to the slag flushing ditch body 1, and the water spray pipes 34 are rotatably connected to a rotating nozzle 341; the water spray pipes 34 are installed with a water pressure gauge 342 and a flow meter 343; the water spray pipes 34 are corrugated pipes.
[0051] When in use, the water spray pipe 34 provided by the present invention is used to spray the water in the cold water tank 3 through the rotating nozzle 341, wherein the pipe diameter is changed to a pipe diameter of 28 to 35 mm, so that the pressure of the slag flushing water is increased and the spray is concentrated, and the bellows are selected for easy bending; a low-pressure swirl type rotating nozzle 341 is adopted, which uses the kinetic energy of the water flow itself to rotate, reducing dependence on external water pressure; the water pressure is monitored by a water pressure gauge 342, and the backup water pump is automatically started when it is lower than the set threshold; the water flow in the water spray pipe 34 is monitored by a flow meter 343, and an alarm is triggered when the deviation exceeds 10%, indicating that the nozzle is blocked or the pipeline is leaking.
[0052] Further, if Figure 8 As shown, both ends of the side walls of the cold water tank 3 are fixed with mounting plates 345, and a rotating frame 344 is rotatably connected between the two mounting plates 345 through a connecting shaft 346, and the water spray pipes 34 are inserted in the rotating frame 344; one end of the connecting shaft 346 is fixed with a gear 347; a second electric push rod 349 is fixed to the mounting plate 345, and the output end of the second electric push rod 349 is fixed with a rack 348, and the racks 348 are respectively engaged with adjacent gears 347, and the racks 348 are slidably connected to the mounting plate 345.
[0053] When the gear 347 and rack 348 provided by the present invention are in use and the water spraying range needs to be expanded, the second electric push rod 349 is turned on, and the rack 348 is driven to move by the output end of the second electric push rod 349, and the gear 347 is driven to rotate back and forth by the rack 348, and the connecting shaft 346 is driven to rotate by the gear 347, and the rotating frame 344 is driven to rotate by the connecting shaft 346, and the water spray pipe 34 is driven to rotate by the rotating frame 344, thereby adjusting the water spraying angle of the water spray pipe 34 and improving the flushing effect.
[0054] Working principle: By installing the inclined flow plate 21 above the slag flushing ditch body 1 and setting a certain slope, it is ensured that after the iron oxide falls on the inclined flow plate 21, it is flushed into the slag flushing ditch body 1 in the middle of the inclined flow plate 21 by the secondary cold water in production. Since slopes are set on both sides and a groove-shaped arc surface is set on the bottom, the impact area of the slag flushing water is reduced, the water column is concentrated, and the impact force is increased. In addition, the inclined flow plates 21 on both sides are welded and polished to make the surface smooth and not easy to accumulate iron oxide, which can ensure that the iron oxide is flushed clean, reduce the difficulty of iron oxide cleaning, and reduce the cost of iron oxide cleaning. The secondary cold water in production is used to directly flush and clean the iron oxide, which can not only directly enter the slag flushing ditch body 1 for cleaning, but also help to cool down the area above the inclined flow plate 21, thereby extending the service life of the inclined flow plate 21. ; When the oxidized slag is large or accumulates on the diagonal flow plate 21, it is necessary to open the oil cylinder 131, and drive the slider 133 to move through the output end of the oil cylinder 131. During the movement of the slider 133, the slider 133 slides on the slide rail 132, thereby pushing the diagonal flow plate 21 to rotate upward around the rotating axis; when it is necessary to expand the water spraying range, the second electric push rod 349 is opened, and the output end of the second electric push rod 349 is used to drive the rack 348 to move, and the rack 348 drives the gear 347 to rotate back and forth, and the gear 347 drives the connecting shaft 346 to rotate, and the connecting shaft 346 drives the rotating frame 344 to rotate, and the rotating frame 344 drives the water pipe 34 to rotate, thereby adjusting the water spraying angle of the water pipe 34 and improving the flushing effect.
[0055] The water level gauge 11 is used to monitor whether there is obvious water level change at both ends of the slag flushing ditch body 1. If the difference between the two water level gauges 11 is higher than the set threshold value, the second motor 324 is controlled by the control program, and the threaded rod 325 is driven to rotate by the second motor 324, and the lifting plate 322 is driven to move up and down by the threaded rod 325, and the scraper 321 is driven to move up and down by the lifting plate 322. When cleaning is required, the scraper 321 is driven to descend and fit the bottom inner wall of the slag flushing ditch body 1; then the reciprocating screw rod 312 is driven to rotate by the output shaft of the first motor 316, and the reciprocating screw rod 312 drives the moving seat 313 to move during the rotation process, and the moving seat 313 drives the scraper 321 to move during the movement, and the oxidized slag in the slag flushing ditch body 1 is pushed out and cleaned by the scraper 321; the moving seat 313 drives the exhaust hood 314 and the exhaust fan 315 to move during the movement, so as to accelerate the discharge of water vapor and maintain the humidity conditions in the workshop;
[0056] When inspection is required, the output end of the first electric push rod 334 drives the connecting frame 332 to move outward, and the connecting frame 332 drives the blocking plate 331 to move outward. The blocking plate 331 leaves the protective box 33 and releases the blockage. Then the electric telescopic rod 335 is opened, and the electric telescopic rod 335 drives the probe 336 to move downward through the output end, so as to facilitate observation of the wear condition of the surface of the protective plate 2 and timely feedback of the wear condition to the control program, so that the control program can issue an alarm reminder.
