Description

Technical Field

[0001] This utility model belongs to the field of metallurgical slag resource utilization technology, specifically relating to a continuous casting machine for molten metallurgical slag, which is suitable for efficient continuous casting and molding of various metallurgical slags. Background Technology

[0002] With rapid industrial development, the amount of slag produced is increasing daily. As a byproduct of industrial production, slag, if not properly utilized, will not only waste resources but also place a heavy burden on the environment. In the casting process, the common gravity casting method is inefficient in the context of large-scale industrial production and cannot meet the market's large demand for castings. Meanwhile, traditional metallurgical slag casting equipment has low mold replacement efficiency, typically employing an integral structure. When mold replacement is needed, the entire mold assembly must be disassembled and the machine stopped. Furthermore, due to the high temperatures and mechanical stresses experienced during long-term use, bolt jamming and component deformation may occur, further increasing the difficulty of disassembly. This seriously affects the continuity of production in industrial settings, resulting in significant waste of time and labor costs, and reducing equipment utilization and production efficiency. In addition, because ordinary molds are made of common steel or ceramic, they are prone to high-temperature oxidation or thermal fatigue, leading to short lifespans and poor resistance to thermal fatigue. During repeated heating and cooling processes, cracks or even breakage can easily occur.

[0003] Patent CN200610043667.5 describes the preparation of ultrathin microcrystalline glass using roller compaction technology, primarily focusing on process optimization for thin-plate forming. This patent, however, is specifically designed for continuous casting of large-size plates with metallurgical slag, utilizing heat-resistant stainless steel, cast iron, or graphite molds adapted to the characteristics of high-temperature slag.

[0004] Patent CN222221084U optimizes the smoothness of equipment operation during track changes through the coordinated design of the trolley track and lateral movement device. Its core innovation lies in the improvement of track layout and transmission structure. This patent, on the other hand, adopts a modular mold assembly and a rotary drive mechanism, focusing on the coordinated control of rapid mold replacement and continuous casting.

[0005] Patent CN222036788U achieves automatic mold loading and unloading through a 90° layout of the conveyor and cooling water tank, with its technological highlights being improved space utilization and automated operation. In contrast, this patent uses a PID algorithm to control the casting speed and mold rotation speed in conjunction with a residual material coating to improve demolding efficiency, further enhancing demolding accuracy and temperature management efficiency. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this utility model provides a continuous casting machine for molten metallurgical slag, which solves the problems of cumbersome mold replacement, low demolding accuracy, and uneven cooling in existing metallurgical slag casting equipment.

[0007] The technical solution provided by this utility model is as follows:

[0008] This utility model provides a continuous casting machine for molten metallurgical slag, including a multi-layered frame structure arranged concentrically. The multi-layered frame structure includes a main frame, a running frame, and a central drive frame connected sequentially from the outside to the inside. Both the running frame and the central drive frame are regular polygonal. A rotary drive mechanism is arranged at the bottom of the central drive frame. A rotary support system is provided below the running frame. The rotary support system includes a circular guide rail arranged concentrically with the main frame. A guide wheel fixedly connected to the running frame is embedded in the circular guide rail. The main frame includes an outer frame and an inner frame connected together. A number of molds are evenly distributed circumferentially between the outer frame and the inner frame. A casting bucket for pouring casting liquid into the mold is provided above the main frame. A flipping mechanism for demolding and resetting the mold is installed on the outer periphery of the outer frame.

[0009] Furthermore, the outer frame and the inner frame are respectively provided with an outer bearing seat and an inner bearing seat. The flipping shafts on both sides of the mold are respectively snapped to the outer bearing seat and the inner bearing seat. A Z-shaped rotating rod that cooperates with the flipping mechanism is also installed on the flipping shaft near the outer frame.

[0010] Furthermore, the flipping mechanism is mounted on the outer edge of the outer frame of the main frame via a support frame. The flipping mechanism has two parts: one for resetting the mold and the other for demolding, which is located near the casting barrel. The height of the support frame for the flipping mechanism for resetting the mold is greater than the height of the support frame for the flipping mechanism for demolding.

[0011] Furthermore, the flipping mechanism includes a base plate located above the support frame. A slide rail is fixedly installed on one side of the top of the base plate. A rack is installed on the surface of the slide rail. A meshing gear is provided on the surface of the rack. A rotating rod fixedly connected to one side of the gear is fixedly mounted on the frame plate. A mounting plate passes through the rotating rod. A U-shaped strip that cooperates with the Z-shaped rotating rod is provided on the mounting plate. A hydraulic push rod is provided on the other side of the top of the base plate opposite to the slide rail. A movable plate is fixedly connected to one end of the hydraulic push rod. A mounting frame is fixedly connected to one side of the movable plate. The inner side of the mounting frame is fixedly connected to the rack.

[0012] Furthermore, the bottom surface of the central drive frame is provided with a support plate, and a rotating shaft is mounted on the support plate. The rotating drive mechanism includes a rotary motor, a drive gear, and a driven gear. The output shaft of the rotary motor is fixedly mounted with the drive gear, and the rotating shaft is fixedly mounted with the driven gear. The driven gear is meshed with the drive gear.

[0013] Furthermore, the rotating shaft is provided with a plurality of triangular reinforcing ribs mounted on the support plate in the circumferential direction.

[0014] Furthermore, a mounting plate is installed below the central drive frame via a boom, and a rotary motor is fixed below the mounting plate.

[0015] Furthermore, the rotary support system also includes a circular support base, the circular guide rail is disposed close to the outer edge of the circular support base, and a plurality of support feet are provided below the circular support base.

[0016] Furthermore, the outer and inner frames of the main frame are also equipped with several spray devices.

[0017] Furthermore, the main frame is a circular frame, and several radial beams are uniformly welded circumferentially between the outer frame and the inner frame of the main frame. A mold installation station is formed between two adjacent radial beams. Both the running frame and the central drive frame adopt a regular octagonal frame structure. The eight vertices of the running frame and the central drive frame are axially connected through radial beams. Each vertex of the central drive frame is circumferentially connected to the inner frame of the main frame through a radial beam. A guide wheel is fixedly connected below each vertex of the central drive frame.

[0018] Beneficial effects

[0019] This utility model effectively improves the stability and continuity of equipment operation through a concentric multi-layer frame structure design. The cooperation between the regular polygonal running frame and the central drive frame enhances the power transmission efficiency. The combination of circular guide rails and guide wheels in the rotating support system ensures the smooth rotation of the running frame and reduces mechanical wear. The circumferentially distributed mold layout combined with the automatic casting barrel achieves uniform slag casting and efficient molding. The outer flipping mechanism simplifies the demolding process, avoids the risk of manual intervention, and promotes rapid mold reset to improve production efficiency. The overall structure optimizes the metallurgical slag processing process, reduces energy consumption and maintenance costs, and meets the needs of continuous production.

[0020] This invention employs a bearing seat snap-fit ​​connection method, making mold installation convenient and stable, facilitating mold flipping operations, and enabling easy disassembly in case of damage to a single mold. By setting two flipping mechanisms for demolding and resetting respectively, the continuity and efficiency of the casting operation are improved. The design of support frames at different heights allows demolding and resetting operations to be performed in a reasonable sequence, avoiding operational conflicts and ensuring the smooth progress of the casting process.
