The top of the main frame 1 is fixedly installed with a casting device 2, and the top of the main frame 1 is rotatably connected with a ladle 11 for feeding the casting device 2; the bottom of the main frame 1 is rotatably connected with a rotating platform 3, and the bottom of the main frame 1 is fixedly installed with a chain conveyor 12, and the chain conveyor 12 is arranged on the lower side of the rotating platform 3; in this embodiment, the chain conveyor 12 is arranged under the rotating platform 3 and aligned with the outlet of the crystallizer 33, and is used to transport the casting to the outside. By setting the main frame 1, a variety of casting equipment can be integrated into the interior of the main frame 1 to achieve integration, and a single device can be easily repaired and replaced when the equipment is damaged. By setting the rotating platform 3, a variety of crystallizers 33 of different specifications can be selected, and the specifications of the castings can be flexibly adjusted during production. At the same time, other crystallizers 33 can be replaced and repaired during the production process, shortening the maintenance time of the equipment. By setting up the casting equipment 2, the liquid metal in the ladle 11 can accurately enter the crystallizer 33 on the top of the rotating platform 3 through the casting equipment 2, avoiding the safety hazard caused by the direct dumping of the ladle 11. At the same time, the required crystallizer 33 can be flexibly selected during the production process, so that one crystallizer 33 can work while the other crystallizer 33 dissipates heat, thereby improving the production efficiency in continuous casting.

[0024] like Figure 1 , Figure 3 , Figure 4 As shown, the casting device 2 includes a sliding frame 21, a casting bin 22, a sliding column 23, a screw 24 and a second servo motor 25; the sliding frame 21 is fixedly installed on the top of the main frame 1 by bolts, the second servo motor 25 is fixedly installed on the outer wall of the sliding frame 21 by bolts, two sliding columns 23 are fixedly installed inside the sliding frame 21, the casting bin 22 is slidably connected to the inside of the sliding frame 21 by the two sliding columns 23, and a threaded hole penetrating the casting bin 22 is opened on the side wall of the casting bin 22, and the threaded hole The internal thread is connected with a screw rod 24, one end of which is rotatably connected to the inner wall of the sliding frame 21 through a bearing, and the other end of the screw rod 24 passes through the side wall of the sliding frame 21 and is fixedly connected to the output end of the second servo motor 25 through a coupling; in this embodiment, through holes are opened on both sides of the side wall of the casting bin 22, and the casting bin 22 is slidably connected to the surface of the sliding column 23 through two through holes, and the horizontal heights of the two sliding columns 23 are the same, and the threaded hole is in a vertical relationship with one of the through holes and is at a different horizontal height from the through hole. The specific structure of the casting bin 22 is as follows Figure 1 , Figure 3As shown, a feeding port for docking with the ladle 11 is provided on the top of the casting bin 22. The feeding port is an inverted trapezoidal structure, which is larger at the top and smaller at the bottom. A discharge pipe for feeding the crystallizer 33 is integrally formed at the lower opening. When in use, the second servo motor 25 is started, and the screw rod 24 connected thereto rotates accordingly. The casting bin 22 threadedly connected to the screw rod 24 moves horizontally in the sliding frame 21. When the casting bin 22 is aligned with the crystallizer 33 to be cast, the liquid metal in the ladle 11 is poured into the casting bin 22 for casting. It is worth noting that when the length of the upper opening of the casting bin 22 is at least twice the distance between the center points of the inlets of the crystallizers 33 in the same group, the distance between the pouring port of the ladle 11 and the inlets of the two crystallizers 33 in the same group is equal. At this time, no matter which crystallizer 33 in the same group the casting bin 22 is aligned with, the ladle 11 only needs to be poured at a fixed position to ensure that the liquid metal enters the crystallizer 33 aligned with the casting bin 22.
