Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, and in particular to a continuous casting billet cutting device. Background Art

[0002] Continuous casting billet cutting is a crucial step in the continuous casting process. Its primary purpose is to cut the continuously poured billets into predetermined lengths for subsequent rolling or processing. The specific process flow is as follows: molten steel continuously passes through a water-cooled crystallizer, solidifies into a hard shell, and is continuously drawn out from the bottom outlet of the crystallizer. It is then cooled by water spray and cut into billets once fully solidified.

[0003] Currently, flame cutting is the most commonly used method for cutting continuous casting slabs. Flame cutting involves a combustion reaction between metal and oxygen. The combustion of the gas heats the metal to its ignition point. Because the temperature of the continuous casting slab itself is relatively high, no excessive heat is required to heat the metal to its ignition point, thus achieving slab cutting.

[0004] After searching, the Chinese patent with patent announcement number CN114570899B is an energy-saving cutting device for cutting continuous casting billets, including an operating body, the operating body including a placement seat, a cutting device is arranged on the top of the placement seat, the placement seat is mounted with a conveying frame and a placement piece through a limit block arranged on the top thereof, the placement piece includes a recycling box, and two recycling boxes are provided and are symmetrically distributed with the conveying frame as the center.

[0005] Although the above patent can realize the slitting of continuous casting billets, it still has the following shortcomings in practical application: 1. Lack of follow-up cutting function: The aforementioned patent requires interrupting the continuous casting billet conveying process when cutting the billet, which interrupts the continuous feeding process. This intermittent feeding not only undermines the stability of the continuous casting process, potentially causing problems such as casting speed fluctuations and temperature unevenness, but also increases the equipment response time and cutting waiting period due to frequent starts and stops, affecting production cycle and production line efficiency.

[0006] 2. Lack of a mechanism to correct the continuous casting billets: After being pulled out at high temperature, the continuous casting billets enter the conveying and cutting process. They are prone to deviation during the conveying process, resulting in failure to maintain an ideal straight posture when entering the cutting station. The above patent lacks a mechanism to correct the continuous casting billets and is unable to correct the posture of the continuous casting billets, resulting in problems such as tilted cutting surface, uneven incision and even length error, which affects the cutting accuracy of the finished billets and subsequent processing and use.

[0034] See also Figure 1-Figure 2 The support mechanism includes a rotating shaft 81, a sprocket 82 and a chain 83. The top of the frame 1 is provided with an opening 01 located between the two sets of electric rollers 2. The opening 01 is rotatably connected to the left and right rotating shafts 81. The rotating shaft 81 is connected to the front and rear sprockets 82. A chain 83 is sleeved between the left and right sprockets 82. The chain 83 is located on the inner side of the gantry 3. Connecting blocks 84 are connected to the chain 83 at intervals along its motion trajectory. The two corresponding connecting blocks 84 on the front and rear of the two chains 83 are both rotatably connected. The support roller 85 is used to support the continuous casting billet. When the support roller 85 rotates to the upper position, its top height remains flush with the top of the gantry 3 and the electric roller 2, and the three are on the same horizontal plane to ensure a smooth transition of the continuous casting billet. The upper parts of the two chains 83 are connected to connecting blocks 86, and the connecting blocks 86 are connected to the inner top of the gantry 3. Two annular support plates 87 for supporting the support roller 85 are symmetrically connected in front and back in the opening 01. The annular support plate 87 is located between the two chains 83.

[0035] Before cutting, first adjust the position of the visual inspection module 15 according to the required cutting length of the billet. Control the screw motor 16 to rotate forward, which can drive the sliding block 13 to drive the cross plate 14 to move to the left, thereby driving the visual inspection module 15 to move left synchronously; control the screw motor 16 to reverse, then the sliding block 13 and the cross plate 14 can be moved to the right, thereby driving the visual inspection module 15 to adjust its position to the right to meet the cutting requirements of billets of different lengths. The continuous casting billet can be transported to the right by the electric roller 2, and the visual inspection module 15 is used to take real-time photos of the continuous casting billet, and the collected image information is transmitted to the background terminal for analysis and calculation. When the background terminal measures that the distance the continuous casting billet moves to the right reaches the preset length, the background terminal sends a signal to the controller, which is not shown in the figure. The controller is a prior art and will not be described here.

[0036] After receiving the signal, the controller first controls Motor 1 73 to rotate screw 71, thereby driving nut 72 to move gantry 1 3 rightward. The speed of gantry 1 3 is kept consistent with the conveying speed of the continuous casting billet, ensuring that gantry 1 3 and its components move synchronously with the continuous casting billet. Motor 2 96 is then controlled to rotate gear 97. The meshing action of gear 97 and rack 95 causes the front and rear gears 97 to approach each other, thereby bringing the front and rear sliders 93 closer together. This, in turn, drives the front and rear push rods 94 closer together, pushing the continuous casting billet to center and align, achieving automatic centering correction of the continuous casting billet. This ensures that the continuous casting billet maintains an ideal straight line at the cutting station, ensuring a smooth cut surface, reducing cutting errors, and improving billet cutting accuracy. Then, the control cylinder 91 drives the guide rail 92 to move downward to press the continuous casting billet and fix it on the top of the gantry 3 to prevent the continuous casting billet from jumping up and down due to continuous transportation during the cutting process, further ensuring the flatness of the cutting surface, further reducing the cutting error, and further improving the cutting accuracy of the billet.

[0037] Then the XY axis moving platform 5 is controlled to drive the flame cutting head 6 to move backward to flame cut the continuous casting billet. When the next cutting cycle begins, the XY axis moving platform 5 drives the flame cutting head 6 to move forward to perform the next cutting operation. At the same time, before each cutting, the visual inspection module 15 captures the slit between two adjacent billets and transmits the image information to the background terminal for analysis and measurement. The controller controls the cutting according to the measurement results, thereby ensuring that the length of the billet cut each time is consistent, and further improving the cutting accuracy. Since the gantry 3 and its upper components can synchronously follow the movement of the continuous casting billet and perform the cutting operation, the follow-up cutting function is realized. The cutting operation can be completed without interrupting the continuous conveying of the continuous casting billet, effectively ensuring the continuous feeding of the continuous casting billet and maintaining the stability of the feeding process. It not only avoids the destruction of the stability of the continuous casting billet due to frequent start and stop, but also significantly reduces the risks of drawing speed fluctuations and temperature unevenness. At the same time, it shortens the response time of the continuous casting equipment and the cutting waiting cycle, thereby improving the overall production rhythm and production line operation efficiency.

[0038] When gantry-3 moves rightward, the connecting block 86 drives the chain 83 to rotate, which in turn drives the connecting block 84 to rotate the support roller 85. This prevents the support roller 85 from obstructing the movement of gantry-3, ensuring smooth and unimpeded movement. At the same time, the support roller 85 provides effective support for the continuous casting billet, ensuring smooth transportation and cutting. After completing a cutting operation, motor 2 96 is first controlled to drive gear 97 in reverse rotation, thereby driving the front and rear push rods 94 away from each other, loosening the continuous casting billet. Simultaneously, cylinder 91 is controlled to drive guide rail 92 upward to loosen the continuous casting billet. Then, motor 1 73 is controlled to drive screw 71 in reverse rotation, driving nut 72 to move gantry-3 leftward to reset. The leftward movement speed of gantry-3 is set to exceed the conveying speed of the continuous casting billet, preparing for the next cutting operation.

[0039] See also Figure 5-Figure 7A smoke and dust collecting mechanism is provided on the outer wall of the gantry 3, and the smoke and dust collecting mechanism includes a collecting box 101 installed on the outer wall of the front side of the gantry 3, a material taking port is provided at the front lower part of the collecting box 101, and a blocking block 102 is plugged in the material taking port, an air pump 103 is installed below the collecting box 101 on the outer wall of the front side of the gantry 3, a cylinder 104 is installed at the rear side of the collecting box 101 on the outer wall of the front side of the gantry 3, a feeding channel 105 is connected between the front upper part of the cylinder 104 and the top of the collecting box 101, and a square air intake hood 108 is connected to the side where the two guide rails 92 are close to each other, and the air intake hood 108 is connected to the cylinder 104 through an exhaust hose 107. A filter cartridge 109 for filtering gas and particulate matter is connected inside 104, and the filter cartridge 109 is connected to the air pump 103 through the exhaust pipe 106. A conveying assembly is provided on the cylinder 104 for conveying particulate matter adhering to the outer wall of the filter cartridge 109 upward, and the conveying assembly includes a motor three 1010 installed on the top of the cylinder 104, and the output shaft of the motor three 1010 is connected to a circular plate 1011 located in the cylinder 104, and the circular plate 1011 is located on the upper side of the filter cartridge 109. A spiral blade 1012 is connected to the bottom of the circular plate 1011, and the spiral blade 1012 is slidably mounted on the outer wall of the filter cartridge 109 and contacts the outer wall of the filter cartridge 109 and the inner wall of the cylinder 104.

[0040] Controlling the operation of air pump 103 draws the gas within cylinder 104 through exhaust pipe 106, creating a negative pressure environment within cylinder 104. This draws smoke and molten metal waste generated during the cutting process into cylinder 104 via air intake hood 108 and exhaust hose 107. Gas and particulate matter are filtered by filter cartridge 109. The gas enters filter cartridge 109 and is then drawn outward by exhaust pipe 106 and discharged to a suitable location, while the molten metal waste is trapped outside filter cartridge 109. Simultaneously, controlling motor 3 1010 drives circular plate 1011, which rotates spiral blade 1012, thereby conveying the molten metal waste adhered to the outer wall of filter cartridge 109 upward and directing it through feeding channel 105 into collection box 101 for centralized collection. This device effectively collects smoke and molten metal waste generated during the cutting process, preventing smoke diffusion and waste splashing, thereby improving the safety and cleanliness of the working environment.

[0041] See also Figure 5-Figure 6 A telescopic plate 11 is connected between the top of the guide rail 92 and the inner top of the gantry 2 4, and a telescopic plate 2 12 is connected between the push rod 94 and the inner wall of the gantry 2 4. The telescopic plate 2 12 is located on the inner side of the guide rail 92 on the same side thereof.

[0042] When the guide rail 92 moves downward, it pulls the telescopic plate 11 to extend. When the front and rear push rods 94 move closer to each other, the telescopic plate 2 12 is pulled to extend. The coordinated cooperation between the telescopic plates 11 and 12 can seal the cutting area, preventing the molten metal waste generated during the cutting process from splashing and harming the workers, thereby improving safety and facilitating the extraction of cutting smoke and dust into the barrel 104. When the guide rail 92 moves upward, it pushes the telescopic plate 11 to retract. When the front and rear push rods 94 move away from each other, the telescopic plate 2 12 is pushed to retract.

A liquid infusion hose 18 is connected to the rear side of the nozzle 17. The liquid infusion hose 18 extends to the rear side of the gantry 3. A drainage hose 19 is connected to the right rear side of the collection frame 32. The drainage hose 19 extends to the rear side of the gantry 3. The bottom of the collection frame 32 is designed to be high in the front and low in the back, so that the liquid can automatically flow to the rear and be discharged through the drainage hose 19.

[0044] The high-temperature molten metal scraps generated during the flame cutting of the continuous casting billet will fall into the collection frame 32 for collection. The infusion hose 18 is connected to an external infusion device, and the infusion device is controlled to inject water into the nozzle 17 through the infusion hose 18. The nozzle 17 then sprays the water obliquely downward into the collection frame 32. The water and the high-temperature molten metal scraps are discharged outward through the drainage hose 19 to a suitable location for secondary treatment, so as to prevent the high-temperature molten metal scraps from solidifying and adhering to the collection frame 32 and being difficult to clean.
