Description

Technical Field

[0001] This utility model relates to the field of steelmaking equipment technology, and in particular to a combined adjustable mold device for tying the ladle opening in a steelmaking plant. Background Technology

[0002] In the steel smelting process, the steel ladle is a key piece of equipment for carrying, transferring and refining molten steel, and its service life and safety stability directly affect production efficiency and operational safety.

[0003] Traditional ladle knotting operations typically use fixed molds, whose size and shape are customized according to specific ladle models. However, in actual production, steel plants usually have a variety of ladles with different specifications (such as capacity, ladle opening diameter, tilt angle, etc.) to adapt to different smelting processes and production capacity requirements. This results in a fixed mold only being compatible with one type of ladle, leading to extremely poor versatility. When knotting operations are required for ladles of different specifications, companies need to stock multiple sets of molds, which not only increases equipment procurement costs and storage space but also necessitates frequent mold changes, extending preparation time and reducing production efficiency.

[0004] To improve production efficiency, we propose a combined adjustable mold device for knotting the ladle opening in steelmaking plants. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a combined adjustable mold device for tying the ladle opening in a steelmaking plant.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A combined adjustable mold device for knotting the ladle opening in a steelmaking plant includes a mold assembly, a ladle opening docking mold assembly, and an infrared remote controller. The ladle opening docking mold assembly includes an electric lifting rod, a fixed disc fixedly mounted on the upper side of the output end of the electric lifting rod, a control circuit board and a drive motor fixedly mounted on the upper side of the fixed disc, a rotating column rotatably mounted at the center position of the upper side of the fixed disc, a large gear fixedly mounted on the outer wall of the rotating column, a fixed block fixedly mounted on the upper end of the rotating column, and telescopic rods fixedly mounted around the fixed block. An electric telescopic rod is fixedly connected between the side wall of the fixed block and the side wall of the telescopic rod, and a ladle opening docking cone is fixedly connected to the outer end of the telescopic rod.

[0008] Furthermore, the curvature of each of the aforementioned conical joints is different.

[0009] Furthermore, a standard insert is fixedly connected to the lower side of the cone-shaped fitting at the opening of the package.

[0010] Furthermore, a power interface is fixedly installed at the bottom of the fixed disc, and an infrared remote control receiver is fixedly installed on the lower side of the power interface.

[0011] Furthermore, a gear is fixedly installed on the upper side of the output end of the drive motor, the gear meshes with the large gear, and a heat insulation protective cover is screwed onto the outer side of the fixed disc, through which the rotating column rotates.

[0012] Furthermore, the mold assembly includes two semi-cylindrical mold slots, with a mating plate fixedly connected to the side of each semi-cylindrical mold slot. The two mating plates are screwed together. An mounting plate is fixedly installed on the side wall of the electric lifting rod, and the mounting plate is screwed onto the side wall of the semi-cylindrical mold slot.

[0013] Furthermore, a pouring port is provided on the upper side of the semi-cylinder mold groove, and a ceramic sealing ring is fixedly installed inside the pouring port.

[0014] Compared with related technologies, the combined adjustable mold device for tying the ladle opening in a steel plant proposed in this utility model has the following advantages:

[0015] This invention relates to a combined adjustable mold device for knotting the ladle opening in a steel plant. The device comprises a ladle opening docking mold assembly with four different ladle opening docking cones. This allows for switching between different ladle opening docking cones and the pouring opening, thus accommodating ladles of different specifications. It offers strong versatility. Switching between different specifications of ladle opening docking cones is electrically adjustable, ensuring rapid switching and improving production efficiency. Furthermore, the entire adjustment process is remotely controlled by an infrared remote controller, avoiding the risk of burns from high temperatures during pouring and enhancing safety.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Reference Figures 1-5 A combined adjustable mold device for knotting the ladle opening in a steelmaking plant includes a mold assembly 1, a ladle opening docking mold assembly 2, and an infrared remote controller 3. The ladle opening docking mold assembly 2 includes an electric lifting rod 22, a fixed disc 23 fixedly installed on the upper side of the output end of the electric lifting rod 22, a control circuit board 24 and a drive motor 25 fixedly installed on the upper side of the fixed disc 23, a rotating column 26 rotatably installed at the center position of the upper side of the fixed disc 23, a large gear 27 fixedly installed on the outer wall of the rotating column 26, a fixed block 28 fixedly installed on the upper end of the rotating column 26, telescopic rods 29 fixedly installed around the fixed block 28, an electric telescopic rod 210 fixedly connected between the side wall of the fixed block 28 and the side wall of the telescopic rod 29, and a ladle opening docking cone 211 fixedly connected to the outer end of the telescopic rod 29.

[0024] In this method, the mold assembly 1 includes two semi-cylindrical mold slots 11, and a docking plate 12 is fixedly connected to the side of the semi-cylindrical mold slot 11. The two docking plates 12 are screwed together. An installation plate 21 is fixedly installed on the side wall of the electric lifting rod 22. The installation plate 21 is screwed onto the side wall of the semi-cylindrical mold slot 11. A pouring port 13 is opened on the upper side of the semi-cylindrical mold slot 11. A ceramic sealing ring 14 is fixedly installed inside the pouring port 13. A standard insert 212 is fixedly connected to the lower side of the mouth docking cone 211.

[0025] With the above setup, when it is necessary to switch the sprue-connecting cone 211, the electric lifting rod 22 is activated to extend, causing the standard insert 212 originally inserted inside the pouring opening 13 to exit the insertion range. Subsequently, the drive motor 25 is activated to drive the rotating column 26 to rotate, which in turn drives the fixing block 28 to rotate, rotating the corresponding sprue-connecting cone 211 to the upper side of the pouring opening 13. Then, the electric telescopic rod 210 on the rear side of the sprue-connecting cone 211 is telescopically adjusted, so that the telescopic rod 29 drives the sprue-connecting cone 211 to be aligned directly above the pouring opening 13. Subsequently, the electric lifting rod 22 retracts, causing the standard insert 212 on the lower side of the sprue-connecting cone 211 to be inserted inside the pouring opening 13, which facilitates the subsequent introduction of molten metal into the mold assembly 1.

[0026] In this method, the curvature of the cone 211 connecting to each package opening is different.

[0027] The above setup facilitates the connection of bag openings of different specifications.

[0028] In this method, a power interface 213 is fixedly installed at the bottom of the fixed disc 23, and an infrared remote control receiver 214 is fixedly installed on the lower side of the power interface 213.

[0029] With the above configuration, the infrared remote control receiver 214 receives the operation signal from the infrared remote control 3 and transmits it to the control circuit board 24. The control circuit board 24 controls the various electrical components to coordinate and adjust according to the operation command.

[0030] In this configuration, a gear is fixedly mounted on the upper side of the output end of the drive motor 25, and the gear meshes with the large gear 27. A heat insulation protective cover 215 is screwed onto the outer side of the fixed disc 23, and the rotating column 26 rotates through the heat insulation protective cover 215.

[0031] Through the above-described configuration, the heat insulation cover 215 provides protection for the internal components, preventing them from being affected by the high temperature of the pouring process.

[0032] The working principle of the combined adjustable mold device for tying the ladle opening in a steelmaking plant provided by this utility model is as follows:

[0033] In use, when a specific specification of steel ladle needs to be knotted at the ladle opening, the operator uses an infrared remote control 3 to issue a command. The infrared remote control receiver 214 receives the signal and transmits it to the control circuit board 24. The control circuit board 24 first controls the extension of the electric lifting rod 22, causing the standard insert 212, which might have been inserted into the pouring opening 13, to retract. Subsequently, the drive motor 25 is started, and the gear at its output end drives the large gear 27 to rotate, which in turn causes the rotating column 26 to rotate. The fixing block 28 rotates with the rotating column 26, moving the ladle opening docking cone 211 of the corresponding specification (with matching curvature) above the pouring opening 13. Then, the control circuit board 24 controls the extension and retraction of the electric telescopic rod 210 corresponding to the ladle opening docking cone 211. The position of the ladle opening docking cone 211 is adjusted by the telescopic rod 29 to precisely align it above the pouring opening 13. After adjustment, the electric lifting rod 22 retracts, causing the standard insert 212 to be inserted into the inside of the pouring opening 13 and make tight contact with the ceramic sealing ring 14, completing the docking.

[0034] At this time, molten metal can be poured into the mold assembly 1 through the cone 211. The molten metal enters the cavity formed by the half-cylinder mold groove 11 through the pouring port 13. During operation, the heat insulation cover 215 provides heat insulation protection for components such as the control circuit board 24 and drive motor 25 on the fixed disc 23.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
