Description

Technical Field

[0001] This invention relates to the field of liquid metal casting technology, specifically to a tilting device for liquid metal casting. Background Technology

[0002] Currently, the casting process for ferroalloys or industrial silicon involves pouring liquid material at a uniform speed through a steel ladle into a chute, which then flows onto the surface of the ingot mold for cooling and solidification. The traditional method of tipping over the ladle to dispose of the liquid material involves using a crane's main lifting hook to hoist the ladle filled with high-temperature liquid material to the casting position, and then using an auxiliary lifting hook to lift the bottom of the ladle, causing it to tip over for casting. Using this method, the ladle sways during transport and casting with the crane's movement, posing a significant safety risk. Furthermore, inaccurate control of the tipping angle and the flow rate of the liquid material during casting can lead to flow rate fluctuations or excessive tipping angles that result in slag being poured into the ingot mold, reducing product quality.

[0040] The connecting mechanism 6 includes a connecting frame 63 and a bidirectional threaded rod 64. The connecting frame 63 is fixedly installed inside the bottom of the connecting box 61 by bolts, on the side away from the connecting motor 62. The connecting frame 63 is located above the middle of the two flip-hanging lugs 36. The bottom of the connecting box 61 has equal-length moving grooves on both sides of the connecting frame 63.

Moving blocks are threadedly installed at symmetrical positions at both ends of the bidirectional threaded rod 64, and both moving blocks are slidably connected to the moving groove. The connecting pin 67 is welded to the bottom end of one of the moving blocks near the worm gear 65, and the connecting hole 68 is opened at the bottom end of the other moving block near the worm gear 65. The cross-sectional diameter of the connecting pin 67 is less than or equal to the cross-sectional diameter of the connecting hole 68. By simultaneously bringing the connecting pin 67 and the connecting hole 68 together, the connecting pin 67 is inserted into the connecting hole 68, thereby connecting the rear lug 35 and the flip lug 36.

[0043] Working Principle: In use, this invention first contains high-temperature liquid iron alloy or industrial silicon in a ladle 33. Then, a crane moves the ladle 33 to the support beam at the top center of the support base 1. The two front lugs 34 on the ladle 33 are hung on the crossbar, and the rear lug 35 is aligned with the flip lug 36. The hydraulic cylinder 32 controls the flipping frame 31, causing it to rotate around the connection point with the fixed frame 2. The flipping frame 31 moves the flip lug 36 to the rear lug 35, aligning the center of the rear lug 35 with the center of the flip lug 36. Then, the connecting motor 62 in the connecting box 61 is remotely activated. The connecting motor 62 drives the worm gear 66 to rotate, which in turn drives the worm wheel 65. This causes the bidirectional threaded rod 64 to rotate along with the worm wheel 65. When the bidirectional threaded rod 64 rotates, the moving slot limits the movement of the moving block, thus... Two movable blocks move simultaneously toward the connecting frame 63, each carrying a connecting pin 67 and a connecting hole 68. This allows the connecting pin 67 to insert into the rear hanging ear 35 and the flip hanging ear 36, and then into the connecting hole 68, thus stably connecting the rear hanging ear 35 and the flip hanging ear 36. The connecting mechanism 6 automatically controls the insertion of the connecting pin 67 into the connecting hole 68, automatically connecting the rear hanging ear 35 and the flip hanging ear 36 on the ladle 33. This saves the operator the step of approaching the device and manually inserting the connecting pin 67 into the rear hanging ear 35 and the flip hanging ear 36, avoiding the risk of the operator being burned by the high temperature of the ladle 33. Then, the hydraulic cylinder 32 pushes the flipping frame 31 according to the speed set in the program, causing the ladle 33 to flip upward. When the ladle 33 tilts at a certain angle, the high-temperature liquid material flows out from the ladle nozzle and into the chute 51, realizing the pouring operation.

[0044] During the liquid metal casting process, when the ladle 33 is flipped, because the density of the slag is greater than that of the finished product, the slag is at the bottom of the ladle 33. When the ladle 33 is flipped to a certain angle, the image recognition function of the external video monitoring system detects that the slag is about to reach the ladle nozzle position. The signal is transmitted to the control system of the hydraulic cylinder 32, causing the hydraulic cylinder 32 to stop working and the flipping frame 31 to automatically reset to the horizontal state of the ladle 33.

[0045] During the pouring process, the piston rod of the hydraulic cylinder 32 is in a reciprocating motion. When the piston rod of the hydraulic cylinder 32 extends and retracts in the cylinder body, it drives the cylinder protective cover 41 to move, so that the nylon slider 43 moves in the slide groove 42, thereby ensuring that the gap between the cylinder protective cover 41 and the piston rod of the hydraulic cylinder 32 remains unchanged, and ensuring that the exposed piston rod of the hydraulic cylinder 32 is not burned by high temperature materials while the hydraulic cylinder 32 is working normally.

[0046] After the liquid metal in the ladle 33 is poured into the chute 51, the swing motor 56 is started. The swing motor 56 drives the turntable to rotate, which in turn drives the connecting rod 57 to reciprocate on the turntable. This causes the support roller 55 to reciprocate on the support platform 52. The lower end of the chute 51 is driven to swing back and forth with the support column 53 as the fulcrum. Through the movable connection of the swing cylinder 54 on the support column 53, the chute 51 is made to swing back and forth, so that the liquid metal in the chute 51 can flow out quickly. In addition, the use of the chute swing mechanism 5 can effectively prevent the liquid metal from impacting a certain position of the casting mold, thereby improving the service life of the casting mold and significantly reducing application and maintenance costs.
