Description

A portable oxygen-fired casting equipment Technical Field

[0001] This invention relates to the field of metallurgical casting technology, and in particular to a portable oxygen-fired casting device. Background Technology

[0002] In the continuous casting process of iron and steel metallurgy, due to improper control of molten steel temperature, excessively long casting intervals, or poor condition of the nozzle itself, the molten steel in the ladle nozzle often condenses and freezes, causing nozzle blockage and preventing the steel flow from being smoothly opened. At this time, it is necessary to use oxygen to deal with the problem, that is, to use the huge heat generated by the combustion of the oxygen blowing pipe at high temperature to melt the cold steel frozen in the nozzle. However, in the current technology, when performing oxygen blowing to start casting, the operator must stand directly under the ladle, hold a hollow metal oxygen blowing pipe several meters long at close range, align one end with and press it against the frozen nozzle, and connect the other end to the high-pressure oxygen pipeline. Moreover, because the tip of the oxygen blowing pipe will burn violently and continuously consume oxygen when it comes into contact with the high-temperature cold steel in the pure oxygen environment, the operator needs to push it forward continuously to maintain the oxygen blowing effect.

[0003] However, the operators are directly exposed to the high-temperature area below the ladle. Once oxygen combustion is successful, the high-temperature steel flow will be instantaneous, which can easily cause splashing or falling, and safety cannot be guaranteed. In addition, the length of a single oxygen blowing pipe is limited. When the sprue is frozen to a large depth, a single oxygen blowing pipe cannot reach the bottom and must be replaced during combustion. This will cause discontinuity in the operation, resulting in serious heat loss in the sprue area, which seriously affects the success rate of oxygen combustion and the overall operation efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a portable oxygen-fired water casting device, which solves the technical problems of low safety and low success rate during oxygen-fired water casting. It features automatic continuous pipe feeding and effective self-protection, thus significantly improving safety and success rate.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a portable oxygen-fired casting equipment, comprising a quick-installation mechanism that can be detachably installed on the outside of a ladle assembly, an automatic feeding mechanism below the quick-installation mechanism, and a protective shielding mechanism at the upper end of the automatic feeding mechanism. The quick-installation mechanism is used to quickly fix the equipment to the ladle assembly, the automatic feeding mechanism is used to uniformly convey the oxygen blowing pipe, and the protective shielding mechanism is used to protect the automatic feeding mechanism and prevent molten steel from falling onto it. The automatic feeding mechanism includes a mounting frame, with a fixed base and a movable base symmetrically arranged on the inner side of the mounting frame. The fixed base is fixedly connected to the mounting frame, and a miniature push rod is provided between the movable base and the mounting frame. Feeding wheels are movably installed on the fixed base and the movable base, respectively. A feeding motor that drives the feeding wheels is provided on the outer side of the fixed base, and an oxygen blowing pipe is provided between the two feeding wheels. When the feeding wheels rotate under the action of the feeding motor, the oxygen blowing pipe moves up or down, thereby achieving automatic feeding.

[0006] Preferably, the feeding wheel is fixedly equipped with an anti-slip rubber sleeve, which can effectively increase the friction between the feeding wheel and the oxygen blowing pipe and avoid slippage during the feeding process.

[0007] Preferably, the quick installation mechanism includes a telescopic straight plate fixedly connected to the installation circular frame, a support plate fixedly installed at the end of the telescopic straight plate, a fixing ball provided at the upper end of the support plate, an installation clamp detachably installed on the outside of the ladle assembly, a fixing protrusion provided on the outside of the installation clamp, a limiting circular groove provided at the lower end of the fixing protrusion, the number of fixing protrusions being the same as the number of support plates, and the fixing ball being able to be inserted into the interior of the limiting circular groove.

[0008] Preferably, a groove is provided on the side wall of the limiting circular groove, a wedge block is movably installed in the groove, a spring is fixedly installed between the wedge block and the groove, and an electromagnet is fixedly installed in the groove. Initially, the wedge block will extend into the limiting circular groove under the action of the spring. When the fixed ball is inserted into the limiting circular groove, the wedge block will limit the fixed ball.

[0009] Preferably, the mounting clamp is provided with fastening bolts. By tightening the fastening bolts, the circumference of the mounting clamp can be adjusted within a certain range to accommodate steel ladle assemblies of different sizes.

[0010] Preferably, the protective shielding mechanism includes an elastic strut, the lower end of which is fixedly connected to the mounting circular frame, and a rubber ball fixedly installed on the upper end of the elastic strut. A circular baffle is provided above the elastic strut, and a limiting sleeve is fixedly installed on the lower end of the circular baffle. The inner diameter of the limiting sleeve is larger than the diameter of the elastic strut. An clearance groove is provided in the middle of the circular baffle. The upper end of the elastic strut is located inside the limiting sleeve. The elastic strut and the circular baffle are in contact through the rubber ball, thereby ensuring that the circular baffle will not fall off the elastic strut and that the circular baffle can tilt to a certain extent.

[0011] Preferably, the diameter of the clearance channel is larger than the diameter of the oxygen blowing pipe. A fireproof cloth assembly is fixedly installed at the upper end of the clearance channel. An elastic rope is provided inside the upper edge of the fireproof cloth assembly. When the oxygen blowing pipe passes through the clearance channel, it will push the fireproof cloth assembly upward. Moreover, as the oxygen blowing pipe moves upward, the fireproof cloth assembly will always be in an arched state, thereby preventing molten steel from falling downward through the clearance channel.

[0012] Preferably, an annular barrier is fixedly installed at the upper end of the circular baffle, and a discharge notch is provided on the annular barrier. Molten steel that falls after the cold steel melts will fall onto the circular baffle, causing the circular baffle to tilt. Subsequently, the molten steel will be discharged through the discharge notch.

[0013] By means of the above technical solution, the present invention provides a portable oxygen blowing and pouring equipment, which has at least the following beneficial effects: 1. The present invention, by setting an automatic feeding mechanism and adopting a symmetrically arranged fixed base and movable base, can flexibly adjust the clamping force. In addition, the surface of the feeding wheel is provided with an anti-slip rubber sleeve, which can further enhance the friction and effectively ensure that the oxygen blowing pipe does not slip or deviate during the conveying process. The structure is simple and reliable, and can be used for a long time in high-temperature and dusty industrial environments, which can fundamentally reduce the safety risks of manual operation.

[0014] 2. This invention, by setting up an automatic feeding mechanism, utilizes the cooperation between the feeding motor and the feeding wheel to deliver oxygen blowing pipes at a uniform speed and stably. This not only overcomes the problems of discontinuous feeding, fatigue, and poor centering accuracy of traditional manual pipe feeding, but also allows for continuous pipe feeding even when the nozzle is deeply frozen. It can effectively avoid heat interruption and nozzle re-condensation caused by pipe replacement in the middle, significantly improving the success rate of oxygen blowing and casting on the first attempt, and providing a guarantee for continuous production.

[0015] 3. This invention, by setting up a quick installation mechanism, can adapt to steel ladle components of different sizes by installing clamps and fastening bolts, and the telescopic straight plate can synchronously adjust the position of the equipment, which can ensure that the oxygen blowing pipe is aligned with the water inlet. This design does not require modification of the existing steel ladle component structure, and the installation process is simple and quick, which can significantly reduce equipment deployment time and labor costs.

[0016] 4. By setting up a quick installation mechanism, the present invention utilizes the cooperation between the wedge block and the electromagnet to automatically lock and fix the ball during installation, which can effectively improve the stability of the equipment in a vibration environment. Furthermore, during disassembly, the wedge block is released by energizing the electromagnet, which can realize remote unlocking and avoid personnel staying in the high-temperature area of ​​the ladle assembly for a long time, further improving the safety and intelligence of the operation.

[0017] 5. By setting up a protective shielding mechanism, the circular baffle will naturally tilt under the action of gravity when the molten steel falls, so that the molten steel is discharged to the side along the discharge gap. This can effectively prevent the molten steel from contacting the automatic feeding mechanism. At the same time, a fireproof cloth assembly with elastic rope is set at the avoidance channel, which can automatically form a dynamic seal as the oxygen blowing pipe rises, which can effectively prevent the molten steel from seeping down through the avoidance channel, thus achieving all-round protection for the core components.

[0018] 6. By setting up a protective shielding mechanism, the invention utilizes the cooperation between the elastic support rod and the limiting sleeve to enable the circular baffle to have a certain floating ability. This allows it to adaptively tilt and discharge slag when impacted by molten steel, and to return to a horizontal state when there is no load. It does not affect the normal entry and exit of the oxygen blowing pipe and combustion. While ensuring equipment safety, it also takes into account the continuity and stability of oxygen burning operation. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] In the prior art, during oxygen-fired casting, operators are directly exposed to the high-temperature area below the ladle. Once oxygen combustion is successful, the high-temperature steel flow is instantaneous, which can easily cause splashing or falling, compromising safety. Furthermore, the length of a single oxygen blowing pipe 5 is limited. When the nozzle freezes to a large depth, a single oxygen blowing pipe 5 cannot reach the bottom and must be replaced midway through combustion, causing discontinuous operation and resulting in severe heat loss in the nozzle area. This seriously affects the success rate of oxygen-fired casting and the overall operational efficiency. To address this technical deficiency in the existing technology, as shown in Figures 1 and 2, this embodiment proposes a portable oxygen-blowing casting device, which can fundamentally reduce the safety risks of manual operation. The device includes a quick-installation mechanism 2 that can be detachably installed on the outside of the ladle assembly 4. An automatic feeding mechanism 1 is provided below the quick-installation mechanism 2, and a protective shielding mechanism 3 is provided at the upper end of the automatic feeding mechanism 1. The quick-installation mechanism 2 is used to quickly fix the device to the ladle assembly 4. The automatic feeding mechanism 1 is used to uniformly convey the oxygen blowing pipe 5. The protective shielding mechanism 3 is used to protect the automatic feeding mechanism 1 and prevent molten steel from falling onto the automatic feeding mechanism 1.

[0023] Specifically, the automatic feeding mechanism 1 includes a mounting frame 101. A fixed base 102 and a movable base 103 are symmetrically arranged on the inner side of the mounting frame 101. The fixed base 102 is fixedly connected to the mounting frame 101. A miniature push rod 106 is arranged between the movable base 103 and the mounting frame 101. Feeding wheels 104 are movably mounted on the fixed base 102 and the movable base 103, respectively. A feeding motor 105 for driving the feeding wheels 104 is provided on the outer side of the fixed base 102. An oxygen blowing pipe 5 is arranged between the two feeding wheels 104. When the feeding wheels 104 rotate under the action of the feeding motor 105, the oxygen blowing pipe 5 will move up or down, thereby realizing automatic feeding. An anti-slip rubber sleeve 107 is fixedly installed on the feeding wheels 104, which can effectively increase the friction between the feeding wheels 104 and the oxygen blowing pipe 5 and avoid slippage during the feeding process.

[0024] As can be seen from the above, when using this equipment to melt the cold steel in the sprue, the workers will first use the quick installation mechanism 2 to fix the equipment to the ladle assembly 4 and make the installation frame 101 coaxial with the sprue of the ladle assembly 4.

[0025] Next, as shown in Figure 1, the upper end of the oxygen blowing pipe 5 is passed between the two feeding rollers 104, and the lower end of the oxygen blowing pipe 5 is connected to the oxygen supply pipe 6. At the same time, the movable base 103 will move towards the fixed base 102 under the action of the micro push rod 106, so that the feeding rollers 104 and the oxygen blowing pipe 5 are in close contact.

[0026] Subsequently, the feeding impeller 104 will rotate under the action of the feeding motor 105, thereby extending the upper end of the oxygen blowing pipe 5 into the interior of the sprue. At the same time, the high-pressure oxygen in the oxygen supply pipe 6 will be sprayed out from the upper end of the oxygen blowing pipe 5 and come into contact with the cold steel in the sprue. Then, the end of the oxygen blowing pipe 5 will burn violently in the high temperature and pure oxygen environment, generating extremely high oxidation heat, thereby rapidly melting the cold steel in the sprue.

[0027] This embodiment, by setting up an automatic feeding mechanism 1 and using symmetrically arranged fixed base 102 and movable base 103, can flexibly adjust the clamping force. In addition, the surface of the feeding wheel 104 is provided with an anti-slip rubber sleeve 107, which can further enhance the friction and effectively ensure that the oxygen blowing pipe 5 does not slip or deviate during the conveying process. The structure is simple and reliable and can be used for a long time in high-temperature and dusty industrial environments, which can fundamentally reduce the safety risks of manual operation. Moreover, by setting up an automatic feeding mechanism 1, this embodiment can convey the oxygen blowing pipe 5 at a uniform speed and stably by cooperating with the feeding motor 105 and the feeding wheel 104. This not only overcomes the problems of discontinuous, easy fatigue, and poor centering accuracy of traditional manual pipe feeding, but also allows for continuous pipe feeding when the nozzle is frozen deeply. It can effectively avoid heat interruption and nozzle re-condensation caused by pipe replacement in the middle, which significantly improves the first-time success rate of oxygen firing and casting, and provides a guarantee for continuous production.

[0028] Example 2: To minimize equipment deployment time and labor costs, based on Example 1, as shown in Figures 1-5, this example includes a quick-installation mechanism 2. Specifically, the quick-installation mechanism 2 includes a telescopic straight plate 201 fixedly connected to the mounting frame 101. A support plate 202 is fixedly installed at the end of the telescopic straight plate 201. A fixing ball 203 is provided at the upper end of the support plate 202. An installation clamp 204 is detachably installed on the outside of the steel ladle assembly 4. A fixing protrusion 205 is provided on the outer side of the installation clamp 204. A limit groove 206 is provided at the lower end of the fixing protrusion 205. The number of fixing protrusions 205 is the same as that of the support plate. The number of 202 is the same. The fixed ball 203 can be inserted into the interior of the limiting circular groove 206. A groove is opened on the side wall of the limiting circular groove 206. A wedge block is movably installed in the groove. A spring is fixedly installed between the wedge block and the groove. An electromagnet is fixedly installed in the groove. Initially, the wedge block will extend into the limiting circular groove 206 under the action of the spring. When the fixed ball 203 is inserted into the limiting circular groove 206, the wedge block will limit the fixed ball 203. The mounting clamp 204 is provided with a fastening bolt 207. By tightening the fastening bolt 207, the circumference of the mounting clamp 204 can be adjusted within a certain range to adapt to steel ladle components 4 of different sizes.

[0029] As can be seen from the above, when installing this equipment, the workers will first wrap the mounting clamp 204 around the outside of the ladle assembly 4, and then use the fastening bolts 207 to fix and tighten the mounting clamp 204, thereby fixing the mounting clamp 204 to the outside of the ladle assembly 4.

[0030] Next, manually adjust the telescopic straight plate 201 so that the support plate 202 is below the fixed protrusion 205. Then push the fixed ball 203 on the support plate 202 into the interior of the limiting groove 206. Subsequently, the wedge block will extend under the action of the spring to limit the fixed ball 203, thereby fixing the mounting frame 101 below the steel ladle assembly 4.

[0031] Subsequently, the automatic feeding mechanism 1 will automatically melt the cold steel in the sprue. After melting, the wedge block will first retract into the groove under the magnetic attraction of the electromagnet. Then, the staff will separate the support plate 202 from the mounting clamp 204, and finally remove the mounting clamp 204 from the ladle assembly 4.

[0032] This embodiment, by setting up a quick installation mechanism 2, can accommodate ladle components 4 of different sizes by using the mounting clamp 204 and fastening bolts 207. Furthermore, the telescopic straight plate 201 allows for synchronous adjustment of the equipment position, ensuring alignment of the oxygen blowing pipe 5 with the water inlet. This design eliminates the need to modify the existing structure of the ladle component 4, making installation simple and quick, significantly reducing equipment deployment time and labor costs. Moreover, by using the quick installation mechanism 2, the wedge block and electromagnet work together to automatically lock the fixing ball 203 during installation, effectively improving the stability of the equipment in vibration environments. During disassembly, the wedge block is released by energizing the electromagnet, enabling remote unlocking and preventing personnel from prolonged stays in the high-temperature area of ​​the ladle component 4, further enhancing operational safety and intelligence.

[0033] Example 3: To prevent molten steel from contacting the automatic feeding mechanism 1 and to achieve all-round protection of the core components, based on the above examples, as shown in Figures 1, 2, 6, and 7, this example includes a protective shielding mechanism 3. Specifically, the protective shielding mechanism 3 includes an elastic support rod 301. The lower end of the elastic support rod 301 is fixedly connected to the mounting circular frame 101, and a rubber ball 302 is fixedly installed on the upper end of the elastic support rod 301. A circular baffle 303 is provided above the elastic support rod 301, and a limiting sleeve 304 is fixedly installed on the lower end of the circular baffle 303. The inner diameter of the limiting sleeve 304 is larger than the diameter of the elastic support rod 301. An avoidance groove 305 is provided in the middle of the circular baffle 303. The upper end of the elastic support rod 301 is located inside the limiting sleeve 304. The elastic support rod 301 and the circular baffle 303 are in contact through the rubber ball 302, thereby ensuring both the protection of the molten steel and the protection of the core components. The circular baffle 303 will not fall off the elastic support rod 301, and can also ensure that the circular baffle 303 can tilt to a certain extent. The diameter of the clearance channel 305 is larger than the diameter of the oxygen blowing pipe 5. A fireproof cloth assembly 306 is fixedly installed at the upper end of the clearance channel 305. An elastic rope is set inside the upper edge of the fireproof cloth assembly 306. When the oxygen blowing pipe 5 passes through the clearance channel 305, it will push the fireproof cloth assembly 306 upward. Moreover, as the oxygen blowing pipe 5 moves upward, the fireproof cloth assembly 306 will always be in an arched state, thereby preventing molten steel from falling downward through the clearance channel 305. An annular barrier 307 is fixedly installed at the upper end of the circular baffle 303. A discharge notch 308 is opened on the annular barrier 307. Molten steel that falls after the cold steel melts will fall onto the circular baffle 303, thereby causing the circular baffle 303 to tilt. Subsequently, the molten steel will be discharged through the discharge notch 308.

[0034] As shown in Figure 4, after the oxygen blowing pipe 5 passes between the two feeding rollers 104, it will then pass through the clearance groove 305. During this process, the elastic rope inside the fireproof cloth assembly 306 will rub against the outside of the oxygen blowing pipe 5, causing the fireproof cloth assembly 306 to arch upwards and block the clearance groove 305.

[0035] When the cold steel is melted and after it is completely melted, the falling molten steel will come into contact with the circular baffle 303. Subsequently, the circular baffle 303 will tilt to a certain extent under the gravity of the molten steel, so that the molten steel will be discharged to the outside through the discharge gap 308. This can effectively prevent the molten steel from coming into contact with the automatic feeding mechanism 1 and causing damage to the core components of the equipment.

[0036] Moreover, the fireproof cloth assembly 306 will always block the clearance channel 305, thereby preventing molten steel from falling down through the clearance channel 305, which also improves safety.

[0037] In this embodiment, by setting up a protective shielding mechanism 3, the circular baffle 303 will naturally tilt under the action of gravity when the molten steel falls, so that the molten steel is discharged to the side along the discharge gap 308, which can effectively prevent the molten steel from contacting the automatic feeding mechanism 1. At the same time, a fireproof cloth assembly 306 with elastic rope is set at the avoidance channel 305, which can automatically form a dynamic seal as the oxygen blowing pipe 5 rises, which can effectively prevent the molten steel from seeping down through the avoidance channel 305, thus achieving all-round protection for the core components. Moreover, by setting up a protective shielding mechanism 3, this embodiment utilizes the cooperation between the elastic support rod 301 and the limiting sleeve 304 to give the circular baffle 303 a certain floating ability, so that it can adaptively tilt to discharge slag when the molten steel impacts, and can return to a horizontal state when there is no load, without affecting the normal entry and exit and combustion of the oxygen blowing pipe 5. While ensuring equipment safety, it also takes into account the continuity and stability of oxygen burning operation.

The power supply is also common knowledge in the art.
