Description

Technical Field

[0001] This utility model belongs to the field of billet deburring technology, specifically an online deburring trolley device for a continuous casting workshop in a steel plant. Background Technology

[0002] During the flame cutting process, the molten slag produced by the high-temperature flame melting the metal will flow naturally along the hot cut surface if it is not blown away from the cutting area in time by the cutting oxygen. As the temperature of the billet gradually decreases, this flowing slag will solidify and form irregular burrs along the lower edge of the cut surface. In actual production scenarios, when the billet occasionally deforms due to uneven temperature distribution and uneven stress, causing the cutting surface to deviate from the standard trajectory, the morphology and attachment position of the burrs become more complex. In addition, when the burr roller is nearing the end of its service life, the matching burr blades may become dull and have angular deviations due to long-term wear, which will cause some burrs to be unable to be effectively removed. If these residual burrs are not treated before entering the next rolling process, on the one hand, during the rolling process, the burrs will have violent friction and collision with the surface of the rolls, which will not only leave defects such as indentations and scratches on the product surface, affecting the appearance quality and dimensional accuracy of the product, but in severe cases, it may even lead to structural damage such as cracks in the product, reducing the mechanical properties of the product; on the other hand, the abnormal wear of the rolls by the burrs will significantly shorten the service life of the rolls, increase equipment maintenance costs and downtime for maintenance, and affect the continuity and stability of production. The current method involves having a designated person inspect each cut surface of the billet after it has been cut. If burrs are found, the billet is flipped to an angle suitable for operation using a flapper, and then manually removed with a hand scraper. However, this manual method is unsuitable for billet thicknesses, the scraper wears out quickly, increasing product costs, and the labor intensity is high, resulting in low efficiency. Furthermore, the removal effectiveness is greatly affected by the operator's experience and sense of responsibility, posing certain quality risks. Utility Model Content

[0022] Please see Figures 1 to 4 This utility model relates to an online deburring trolley device for a continuous casting workshop in a steel plant. It includes a mobile trolley body 1, a lifting and adjusting mechanism, a quick-change pipe clamp device, and an oxy-fuel cutting torch assembly 2. A winch 20 is connected to each end of the mobile trolley body 1 in its running direction. The lifting and adjusting mechanism includes a threaded rod 4 and a guide sleeve 5. The guide sleeve 5 is mounted on the mobile trolley body 1, and the threaded rod 4 is threadedly connected to the guide sleeve 5. The quick-change pipe clamp device includes an adjusting arc plate 6, a fixed arc plate 7, and an adjusting groove. The adjusting groove is located at the top of the threaded rod 4, and an adjusting shaft is provided on the adjusting groove. A fixing frame 9 is provided between the adjusting shaft and the fixed arc plate 7. A threaded fastening mechanism and a guiding mechanism are provided between the adjusting arc plate 6 and the fixed arc plate 7. A first threaded hole is provided between one side of the adjusting groove and one side of the threaded rod 4, and a screw 10 is provided in the first threaded hole. The oxy-fuel cutting torch assembly 2 is located between the adjusting arc plate 6 and the fixed arc plate 7.

[0023] Specifically, in this embodiment, a winch 20 is connected to each end of the moving trolley body 1 in the direction of travel. The operation of the winches 20 controls the reciprocating motion of the moving trolley body 1, driving the gas cutting torch assembly 2 to move reciprocally, thereby achieving secondary deburring. The gas cutting torch assembly 2 is moved between the adjusting arc plate 6 and the fixed arc plate 7. Then, by using the threaded fastening mechanism and the guide mechanism, the adjusting arc plate 6 and the fixed arc plate 7 can clamp the gas cutting torch assembly 2. By rotating the threaded rod 4 in the guide sleeve 5, the height of the gas cutting torch assembly 2 can be adjusted within a specified range by rotating one or more times. The height of the gas cutting torch assembly 2 can be adjusted by raising and lowering. The guide sleeve 5 and the rotating threaded rod 4 are matched with M20×1.5 fine threads. The rotating threaded rod 4 is marked with a scale in 5mm increments. The thickness of the billet can be adaptively adjusted by the rotating threaded rod 4 with the scale markings. Then, by rotating the fixing frame 9 through the adjusting shaft 8 in the adjusting groove, the angle of the fixing arc plate 7 is adjusted, thereby adjusting the horizontal angle of the gas cutting gun assembly 2, which facilitates the adjustment of the orientation of the gas cutting gun assembly 2 and facilitates the gas cutting of the billet burrs on one side of the moving trolley body 1. Then, by rotating the screw 10 in the first screw hole, one end of the screw 10 can be fixed on the fixing frame 9, thereby fixing the angle of the adjusting shaft 8 and fixing the angle of the gas cutting gun assembly 2.

[0024] Furthermore, the online deburring trolley device for a continuous casting workshop in a steel plant according to this utility model also includes an electrical control module. The electrical control module is electrically connected to the winch 20 and adopts a PLC + frequency converter. Through the gas cutting spray gun assembly 2, the device can automatically perform gas cutting deburring operations on the cast billet. The combination of the deburring winch 20 with the electrical control module PLC + frequency converter is a common and well-known technique in the prior art, and will not be described in detail here.

[0025] Furthermore, this device also includes a visual inspection closed loop, comprising an industrial camera electrically connected to an electrical control module. A surface inspection system based on the industrial camera and a PLC form a PID control loop to achieve real-time feedback on deburring quality. If the surface inspection system indicates that burrs have not been removed, the trolley must automatically slow down and retreat to repeat the operation. The surface inspection system includes several surface inspection feedback units, each comprising a 2-megapixel industrial camera and a burr recognition algorithm.

[0026] Furthermore, this device achieves precise removal of burrs from cast billets through the synergistic effect of the thread-adjustable gas cutting torch assembly 2 and the vision inspection system. Compared with existing technologies, it has advantages such as strong adaptability (supporting thicknesses of 200-400mm), high operating efficiency, and controllable quality, making it particularly suitable for high-paced continuous casting production lines.

[0027] To facilitate flexible assembly or disassembly of the gas cutting spray gun assembly 2, the threaded fastening mechanism in this design includes an adjusting plate 11 and a locking plate 12. The adjusting plate 11 is installed at the top of the adjusting arc plate 6, and the locking plate 12 is installed at the top of the fixed arc plate 7. The adjusting arc plate 6 has an adjusting hole, and the locking plate 12 has a second threaded hole. A bolt 13 is installed in the second threaded hole. One end of the bolt 13 passes through the adjusting hole and is fitted with a nut. The bolt 13 is tightened through the adjusting hole and the second threaded hole. Pressure is applied through the nut to clamp the spray gun between the adjusting arc plate 6 and the fixed arc plate 7. When the bolt 13 is loosened, the adjusting arc plate 6 can move along the adjusting hole, thus enabling quick assembly and disassembly of the gas cutting spray gun assembly 2.

[0028] To improve the service life of this device, four omnidirectional high-temperature resistant rollers 3 are symmetrically arranged at the bottom of the mobile trolley body 1. A slide rail is located below each of the omnidirectional high-temperature resistant rollers 3 on the working surface. The mobile trolley body 1 slides along the slide rail via the omnidirectional high-temperature resistant rollers 3, achieving automatic movement at speeds of 0.5m / min to 2m / min. The high-temperature resistant rollers improve the service life of the device, while the slide rail makes the movement trajectory more reliable and the removal of burrs more precise. The omnidirectional high-temperature resistant rollers 3 are made of cast iron with a high-temperature resistant ceramic coating. The cast iron body provides high strength, and the ceramic coating forms a high-temperature resistant and wear-resistant layer, enabling stable operation in environments up to 400℃.

[0029] To improve the linear movement stability of the adjusting arc plate 6, in this scheme, the guiding mechanism includes a guide plate 14 and a guide post 15. The guide post 15 is installed on one side of the fixed frame 9, and the guide plate 14 is installed at the bottom of the adjusting arc plate 6. The guide plate 14 has a guide hole, and the guide post 15 passes through the guide hole. When the adjusting arc plate 6 moves, the guide post 15 restricts its radial displacement, ensuring that the adjusting arc plate 6 moves smoothly along the axial direction.

[0030] To adapt to the high-temperature environment of the continuous casting workshop, the mobile trolley body 1 in this design adopts a metal frame structure, welded from high-temperature resistant steel. The frame is made of Q345B high-temperature resistant steel, which maintains high strength even at 600℃, and the welded structure ensures frame rigidity. Adapting to the high-temperature environment of the continuous casting workshop, the frame is not easily deformed, extending the equipment's service life.

[0031] To accommodate castings of different sizes, the lifting stroke range of the threaded rod 4 and guide sleeve 5 in this design is 50-300mm. It can accommodate castings of different sizes from 100mm×100mm to 400mm×400mm, requires no manual disassembly of the equipment, has a short adjustment time, and is easy to use.

[0032] To prevent the mobile trolley body 1 from shifting, the anti-shift positioning mechanism in this design includes a magnetic positioning block 16 and a positioning plate 17. The magnetic positioning block 16 is installed on one side of the top of the mobile trolley, and the positioning plate 17 is installed on one side of the bottom of the mobile trolley. The positioning plate 17 has a third screw hole with a positioning pin 18 for positioning with the edge of the billet. The magnetic positioning block 16 uses permanent magnet attraction to adhere to the upper surface of the billet, and the positioning pin 18 is inserted into the positioning groove at the edge of the billet, achieving dual positioning through magnetic force and mechanical locking. To prevent lateral shifting during trolley movement, the anti-shift angle mechanism ensures that the mobile trolley body 1 moves along the edge of the billet, maintaining a stable distance between the spray gun and the burr area, and avoiding incomplete deburring due to shifting.

[0033] To ensure the overall positioning accuracy of the trolley, in this design, anti-deviation positioning mechanisms are installed on both sides of the moving trolley body 1, with two mechanisms on each side to evenly bear the reaction force of the billet on the trolley. This enhances positioning stability, ensuring the overall positioning accuracy of the trolley even if local deviation occurs due to thermal deformation of the billet.

[0034] To improve the heat insulation performance of the mobile trolley body 1, a heat insulation layer 19 structure is provided on the top of the mobile trolley body 1 in this design. The heat insulation layer 19 is composed of a ceramic fiber blanket and a metal protective plate, which is used to isolate the high temperature generated by gas cutting operations. The ceramic fiber blanket blocks high temperature radiation, and the metal protective plate prevents wear on the fiber blanket. The combination of the two forms a 50mm thick heat insulation layer 19, which improves the high temperature resistance of this structure.

[0035] During the preparation phase, the threaded rod 4 rotates within the guide sleeve 5, achieving precise positioning and adjustment of the lifting mechanism with an accuracy of ±0.1mm via threaded transmission. The gas cutting spray gun assembly 2 is placed between the adjusting arc plate 6 and the fixed arc plate 7, and the spray gun is clamped by the threaded fastening mechanism. The adjusting shaft in the adjusting groove is rotated, driving the fixing frame 9 to adjust the horizontal angle of the spray gun. Subsequently, the screw 10 in the first screw hole is tightened to fix the adjusting shaft, ensuring the stability of the spray gun angle. The traction device is a type JM-3 winch, which pulls the moving trolley via a wire rope. The PLC + frequency converter control module controls the movement according to the connection... The casting machine's pulling speed is 0.5-2 m / min, and the trolley's traveling speed is automatically adjusted to ensure synchronization with the billet conveying. The oxygen and acetylene pressures of the gas cutting torch are adjusted to 0.5-0.8 MPa and 0.02-0.05 MPa respectively. After ignition, the burrs on the edge of the billet are cut. Then, the threaded fastening mechanism completes the disassembly of the gas cutting torch assembly 2 and the installation of the new torch. The guiding mechanism ensures that the torch axis position remains unchanged during the replacement process. After the operation is completed, the winch 20 pulls the trolley back to the initial position, the magnetic positioning block 16 is de-energized, and the positioning pin 18 retracts, awaiting the processing of the next billet. The mobile trolley body 1 and frame are made of Q345B high-temperature resistant steel. In continuous casting workshops where the ambient temperature reaches up to 600℃, Q345B steel maintains its structural strength and weldability even at high temperatures, meeting the frame's rigidity requirements. The universal high-temperature resistant rollers 3 have a cast iron body with a ceramic coating, 0.3mm thick. The cast iron provides the basic load-bearing capacity, while the ceramic coating can withstand temperatures up to 400℃, ensuring stable movement of the trolley in high-temperature, dusty environments. The threaded rod 4 is made of 40Cr quenched steel with a hardness of HRC48-52, and the guide sleeve 5 is made of 20# steel with a hard chrome plating thickness of 0. The 0.05mm, 40Cr high strength and wear resistance meet the needs of frequent lifting. The hard chrome plating reduces the coefficient of friction and ensures the smoothness of lifting. The adjusting arc plate 6 and the fixed arc plate 7 are made of 45 steel quenched and the inner surface is inlaid with polytetrafluoroethylene wear-resistant sheets. The quenched steel has high hardness and anti-deformation ability. The polytetrafluoroethylene sheets reduce the wear of the spray gun clamp and extend the service life of the gas cutting spray gun assembly 2. The heat insulation layer 19 is a ceramic fiber blanket plus a stainless steel protective plate. The ceramic fiber blanket effectively blocks high temperature radiation and has a heat insulation efficiency of ≥80%. The stainless steel plate prevents the fiber blanket from wearing and keeps the temperature of the top of the trolley below 60℃, protecting the electrical components.

[0036] Deburring precision: For 200mm×200mm Q235B billets cut to a surface temperature of 800℃, deburring operation was performed. The average residual burr height was 0.25mm (industry standard ≤ 0.5mm), positioning deviation ≤ 0.3mm, and the first-pass deburring pass rate was 99.2%, compared to only 85% for traditional equipment. With a continuous casting machine speed of 2.8m / min and a billet length of 12m, the deburring time for a single billet was 2 minutes and 15 seconds (compared to 7 minutes and 30 seconds for traditional equipment). Daily processing capacity increased from 120 billets to 320 billets, increasing annual capacity by approximately 80,000 tons. Spray gun replacement time was reduced from 1.5 hours to 5 minutes, and annual downtime was significantly reduced. The machine maintenance time is reduced by 105 hours, maintenance costs are reduced by 60%, and annual cost savings are approximately 350,000 yuan. The equipment can operate continuously for 8,000 hours without failure in an environment of 400℃, while the average for traditional equipment is 500 hours. The energy consumption per unit casting billet is 0.8 kW•h / t, while that of traditional equipment is 1.5 kW•h / t, resulting in annual electricity savings of approximately 350,000 kWh. When adjusting from 150mm×150mm to 300mm×300mm, the adjustment time is ≤3 minutes, while that of traditional equipment is 2.5 hours. When the casting billet shifts laterally by 10mm, the anti-deviation positioning mechanism can automatically correct, ensuring that the distance fluctuation between the spray gun and the burr is ≤0.5mm.

[0037] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
